Introduction
Top Take-Home Messages
- Treat dyslipidemia earlier to reduce lifelong risk of prolonged exposure to atherogenic lipoproteins. Health behavior counseling to support lifestyle optimization should start in youth, with early consideration of pharmacotherapy in youth with familial hypercholesterolemia (FH) and in young adulthood in individuals with low-density lipoprotein-cholesterol (LDL-C) ≥160 mg/dL or a strong family history of premature atherosclerotic cardiovascular disease (ASCVD).
- Use the more contemporary American Heart Association Predicting Risk of cardiovascular disease EVENTs (PREVENT™) equations instead of the older Pooled Cohort Equations (PCE) for 10- and 30-year risk assessment to guide lipid-lowering therapy (LLT) in primary prevention in adults aged 30 to 79 years. Use the “CPR” Model:
- Calculate 10-year ASCVD risk;
- Personalize the estimated risk to the specific patient by considering factors not included in PREVENT-ASCVD equations; and
- possibly Reclassify with selective use of coronary artery calcium (CAC) and Reassess treatment recommendations.
- LDL-lowering therapy can be considered in adults for primary prevention of ASCVD with a 10-year PREVENT-ASCVD risk estimate of 3% to <5% (borderline risk) and should be considered for those at 5% to <10% (intermediate risk) 10-year risk after a clinician-patient discussion.
- LDL-C and non–HDL-C treatment goals are back to guide LLT. Percentage reduction in LDL-C remains a priority for all individuals as well, with goal for % reduction depending on the level of ASCVD risk.
- Apolipoprotein B (ApoB) testing can be useful to improve risk assessment and guide therapy once LDL-C and non–HDL-C goals are met, particularly in those with elevated triglycerides (TG) (>200 mg/dL), diabetes, or low achieved LDL-C (<70 mg/dL). ApoB measurement helps identify adults with residual elevated lipoprotein-related risk that may be underestimated by the standard lipid profile alone and may be useful in the diagnosis of specific lipid and lipoprotein disorders.
- Lipoprotein(a) [Lp(a)] should be measured at least once to identify those individuals at higher risk of ASCVD. It is considered as a risk-enhancing factor at levels ≥125 nmol/L (50 mg/dL), which is associated with about a 1.4-fold increased ASCVD risk, and values ≥250 nmol/L (100 mg/dL) are associated with ≥2-fold higher estimated risk. The presence of elevated Lp(a) should be an indication for more intensified LDL-C lowering and management of other risk factors.
- Coronary artery calcium (CAC) scoring in men at least 40 years of age and women at least 45 years of age can improve risk assessment and guide LDL-C and non–HDL-C goals. Both the absolute amount of CAC and the corresponding standardized percentile (currently based on age, sex, and race) have prognostic importance and help to reclassify risk in adults.
- LDL-lowering therapy is recommended for primary prevention in adults aged 40 to 75 years with diabetes, chronic kidney disease stage 3 or 4, or human immunodeficiency virus, regardless of LDL-C level. After age 75 years, LDL-C–lowering pharmacotherapy can be considered in conjunction with lifestyle interventions to reduce ASCVD risk.
- In secondary prevention, a goal of LDL-C <55 mg/dL (1.4 mmol/L) and non–HDL-C <85 mg/dL (2.2 mmol/L) is recommended for those at very high risk of ASCVD events. Although a smaller number of patients with ASCVD not at very high risk have an LDL-C goal of at least <70 mg/dL, the majority of those with a history of ASCVD events will likely qualify for an LDL-C goal of <55 mg/dL.
- In patients with persistently elevated TG, statin therapy remains the foundation of pharmacotherapy as an adjunct to lifestyle intervention to reduce ASCVD risk. Treatment for prevention of pancreatitis may also include TG-lowering therapies, especially in individuals with TG levels ≥1000 mg/dL (11.3 mmol/L).
Definitions and Classifications
Note: The numbering of the following tables and figures may differ from that of the Clinical Practice Guideline.
Colors in tables and figures correspond to Class of Recommendations and Level of Evidence tables on pages 104–105.
2.1. Definitions
- Cardiovascular-kidney-metabolic syndrome: The common characteristics of the cardiovascular-kidney-metabolic (CKM) syndrome include abdominal obesity (high body mass index [BMI] and/or large waist circumference), insulin-resistant glucose metabolism (hyperinsulinemia, impaired fasting glucose, impaired glucose tolerance, type 2 diabetes), dyslipidemia (high serum TG and low serum high-density lipoprotein cholesterol [HDL-C] concentrations), increased blood pressure, and sometimes microalbuminuria, proteinuria, or chronic kidney disease (CKD).
- Children: In this guideline, children are defined as age 18 years or younger.
- Clinical ASCVD: ASCVD includes history of acute coronary syndromes (ACS), myocardial infarction (MI), stable or unstable angina, coronary or other arterial revascularization, stroke, transient ischemic attack (TIA), or peripheral artery disease (PAD). ASCVD at very high risk is defined as ≥2 major ASCVD events (ACS within the past 12 months, history of MI [other than recent ACS], history of ischemic stroke, symptomatic PAD) or with 1 major ASCVD event and ≥2 high-risk features (age ≥65 years, coronary bypass or percutaneous intervention, current smoker, diabetes, history of heart failure [HF], hypertension, LDL-C ≥100 mg/dL [2.6 mmol/L] despite maximally tolerated statin plus ezetimibe).
- Dyslipidemias: Dyslipidemias considered in this guideline include elevated blood cholesterol, hypertriglyceridemia, and elevated Lp(a).
- Lifestyle management: Lifestyle management encompasses an assessment of each individual's baseline behavioral habits and counseling regarding healthy lifestyle habits. It includes information regarding heart-healthy eating patterns, regular physical activity, avoidance of all nicotine-delivery products, healthy sleep habits, and maintaining a healthy weight. This includes the lifestyle elements of the AHA’s Life’s Essential 8™ in addition to stress management.
- Subclinical atherosclerosis: Subclinical atherosclerosis is identified by the presence of atheromatous disease in ≥1 arterial territories before there are any signs, symptoms, or events attributable to clinically manifest atherosclerotic disease in those territories.
Evaluation and Diagnosis
3.1. Screening in Children and Adults
1. In adults, screening with a lipid profile is recommended beginning at age 19 years and at least every 5 years thereafter to identify treatable ASCVD risk, with frequent screening recommended for individuals with additional ASCVD risk factors. ( 1, B-NR )
2. In children 9 to 11 years of age not previously tested, it is recommended to screen with a lipid profile to identify familial hypercholesterolemia (FH) and other significant lipid disorders. ( 1, B-NR )
3. In individuals with first- or second-degree relatives with premature ASCVD, severe hypercholesterolemia, or FH, it is reasonable to perform screening with a single lipid profile (eg, cascade screening) starting at ≥2 years of age to identify FH. ( 2a, B-NR )
3.2. Measurement of TC, LDL-C, HDL-C, Triglycerides, and Non–HDL-C
1. In adults and children, a standard nonfasting or fasting lipid profile is recommended to document baseline lipid levels, estimate ASCVD risk, and guide initiation of LLT. ( 1, B-NR )
2. In adults and children with a family history of dyslipidemia or premature ASCVD, a personally known or suspected disorder in TG metabolism, or whose nonfasting lipid profile reveals a TG level ≥400 mg/dL (≥4.5 mmol/L), a fasting lipid profile should be performed to more accurately estimate the LDL-C level. ( 1, B-NR )
3. In adults and children who have undergone a standard lipid profile, use of either the Martin/Hopkins equation or the Sampson/National Institutes of Health (NIH) equation is preferred over calculation by the Friedewald equation to estimate LDL-C. ( 1, B-NR )
4. In adults and children who have undergone a standard lipid profile, use of either the Martin/Hopkins equation or Sampson/NIH equation is preferred over direct LDL-C measurement (other than by beta-quantification) to estimate LDL-C. ( 1, B-NR )
5. In adults and children who have undergone a standard lipid profile, reporting of non–HDL-C is recommended for ASCVD risk assessment and to guide initiation and monitoring of LLT. ( 1, B-NR )
6. In adults and children, routine advanced lipoprotein testing (eg, gradient gel electrophoresis, density gradient ultracentrifugation, nuclear magnetic resonance spectroscopy, ion mobility analysis) to assess lipoprotein subclasses and parameters such as LDL particle size is not recommended to estimate ASCVD risk and guide initiation of LLT. ( 3 - No Benefit, B-NR )
3.3. Measurement of Apolipoprotein B
1. In adults on LLT, particularly those with ASCVD, CKM syndrome, type 2 diabetes, and/or elevated TG, measurement of apoB is reasonable to guide decisions regarding further therapeutic intensification once LDL-C and/or non–HDL-C goals are achieved. ( 2a, B-NR )
2. In adults not on LLT, measurement of apoB may be reasonable to enhance ASCVD risk assessment, guide decisions about initiation of LLT, and characterize inherited lipid disorders. ( 2b, B-NR )
3.4. Measurement of Lipoprotein (a)
1. In all adults, measurement of Lp(a) concentration is recommended at least once for ASCVD risk assessment. ( 1, B-NR )
2. In individuals with FH, premature ASCVD, or high Lp(a), cascade testing of first-degree family members for high Lp(a) concentration is recommended to identify those at increased ASCVD risk. ( 1, B-NR )
3. For individuals undergoing measurement of Lp(a), use of laboratories employing assays that are insensitive to apo(a) isoforms and traceable to official reference standard materials is recommended to more accurately measure Lp(a) and characterize ASCVD risk. ( 1, B-NR )
Table 4. ASCVD Risk Related to Lp(a) Concentrations*
* Lp(a) concentrations in this threshold range may be considered for repeat testing.
Data in the table are derived from the UK Biobank Study, are intended as a general guide and may differ in other populations. For example, relative risk of 2-fold has been observed for levels of 200 nmol/L in some populations. Equivalence of levels between nmol/L and mg/ dL is approximate. An Lp(a) level of 50 mg/dL (125 nmol/L, ~80th percentile) is associated with an ~40% relative risk increase in ASCVD compared with 7 mg/dL (20 nmol/L, median in a reference population). An Lp(a) level of 100 mg/dL (≥250 nmol/L, ~95th percentile) approximately doubles the ASCVD risk. An Lp(a) level of 180 mg/dL (≥430 nmol/L, ~99th percentile) increases the ASCVD risk by ~4-fold, similar to the risk of heterozygous familial hypercholesterolemia.
ASCVD indicates atherosclerotic cardiovascular disease; and Lp(a), lipoprotein (a).
3.5. Monitoring and Follow-Up
1. In individuals on LLT, clinicians should perform a lipid profile 4 to 12 weeks after initiation or dose adjustment and every 6 to 12 months thereafter to assess efficacy and adherence to LLTs. ( 1, A )

Management
4.1. Lifestyle Management
4.1.1. Primordial Prevention of Dyslipidemia: Childhood Through Adulthood
1. In children and healthy adults, healthy dietary patterns, regular physical activity, maintenance of a healthy weight, healthy sleep, stress management, and avoidance of tobacco products should be promoted and reinforced lifelong to reduce the risk for dyslipidemia and ASCVD. ( 1, A )
4.1.2. Dietary Approaches in Dyslipidemia
4.1.2.1. Dietary Management of LDL-C Disorders
1. In adults and children with or without ASCVD, a diet emphasizing intake of fruits, vegetables, nuts, legumes, whole grains, and fiber, while replacing saturated and trans-fat with dietary monounsaturated and polyunsaturated fat, is recommended to decrease LDL-C levels and reduce ASCVD risk. ( 1, B-NR )
4.1.2.2. Lifestyle Management of Hypertriglyceridemia
1. In adults with fasting TG levels of 150 to 499 mg/dL (1.7–5.6 mmol/L), a diet that is low in added sugar, refined carbohydrates, and saturated fat, and that minimizes alcohol (Figure 2) is beneficial to reduce TG and ASCVD risk. ( 1, A )
2. In adults with fasting TG levels of 500 to 999 mg/dL (5.7–11.3 mmol/L), a diet that is low in added sugar, refined carbohydrates, and saturated fat, with no alcohol and individualized limitation of total fat (Figure 2) is beneficial to reduce TG for the reduction of ASCVD risk and risk of pancreatitis. ( 1, B-NR )
3. In adults with fasting TG levels of ≥1000 mg/dL (11.3 mmol/L), a diet that is very low in total fat and refined carbohydrates, with elimination of alcohol and added sugars (Figure 2) is beneficial to reduce TG and risk for pancreatitis. ( 1, B-NR )
4. In adults with fasting TG levels ≥150 mg/dL (1.7 mmol/L) or nonfasting TG levels ≥175 mg/dL (2 mmol/L), improvement in lifestyle factors related to overweight/obesity and CKM syndrome, weight loss of 5% to 10%, moderate-to-vigorous intensity physical activity of ≥150 minutes a week, and upper and lower body resistance exercise 2 days/week (Figure 2) are beneficial to reduce TG. ( 1, B-NR )
4.1.3. Attainment and Maintenance of Healthy Weight in People With Dyslipidemia
1. In individuals with overweight or obesity and dyslipidemia, counseling and treatment to achieve weight reduction and maintenance of a healthy weight are recommended to improve dyslipidemia. ( 1, B-NR )
4.1.4. Physical Activity
1. In individuals with dyslipidemia, regular physical activity that includes moderate-to-vigorous intensity aerobic exercise for ≥150 minutes a week, along with upper and lower body resistance exercise 2 days/week should be recommended as part of a program to improve blood lipids and cardiovascular health. ( 1, B-R )
4.1.5. Dietary Supplements
1. In individuals with dyslipidemia, the use of dietary supplements is not recommended to lower LDL-C or TG based on limited and inconsistent data and/or limited benefits in lipid-lowering and reduction in ASCVD risk. ( 3 - No Benefit, B-R )
4.1.6. When to Refer to a Registered Dietitian Nutritionist
1. In individuals with fasting TG ≥1000 mg/dL (11.3 mmol/L), referral to an RDN is recommended to create an individualized treatment plan aimed at reducing TG and the risk of pancreatitis. ( 1, B-NR )
2. In individuals with fasting TG ≥150 to 999 mg/dL (≥1.7–11.3 mmol/L) and features of the CKM syndrome, referral to an RDN to provide counseling on evidence-based dietary patterns can be beneficial to improve lipoprotein levels and reduce the risk of pancreatitis. ( 2a, B-NR )
Figure 2. Health Behavior Interventions in Patients With Hypertriglyceridemia
* Referral to an RDN and lipid specialist advised.
† Referral to an RDN necessary.
‡ Clinicians may opt to reduce total fat as a percent of calories in some patients to 10% to 15% (examples include those with a history of pancreatitis or those at the higher end of this range).
§ Limitation of total fat to 10% to 15% of total daily intake, with guidance from an RDN is essential for patients with FCS.
¶ For those with TG disorders outside of FCS, individually tailored total fat limitation under the guidance of an RDN can be beneficial due to variable response to diet.
|| Although clinicians should aim for a patient to achieve the guideline-directed amount of physical activity, any physical activity is likely beneficial in sedentary individuals and should be encouraged to reduce cardiometabolic risk.
FCS indicates familial chylomicronemia syndrome; RDN, registered dietician nutritionist; and TG, triglycerides.

4.2.3.1. Role of the Individualized Benefit-Risk Discussion
1. In individuals with dyslipidemia, clinicians and their patients should engage in a discussion of the patient’s ASCVD risk, healthy lifestyle as the foundation of risk reduction, expected risk reduction benefits from LLT, possible harms and DDI, costs, and patient preferences to make individualized treatment decisions and/or consider additional options for evaluation to aid in decision-making.

4.2.3.2. PREVENT-ASCVD Equations
1. In adults aged 30 to 79 years without ASCVD or subclinical atherosclerosis and with an LDL-C level between 70 and 189 mg/dL (1.8–4.9 mmol/L), the PREVENT-ASCVD equations should be used to estimate 10-year ASCVD risk, with categorization as having low (<3%), borderline (3% to <5%), intermediate (5% to <10%), or high (≥10%) 10-year estimated ASCVD risk. ( 1, B-NR )
Table 11. Salient Features of the American Heart Association PREVENTTM* Equations
The PREVENT equations:
- Included a large, contemporary, representative sample of U.S. adults for derivation (N ~3.3 million) and external validation (N ~3.3 million).
- Lower limit to begin risk prediction to age 30 years (through 79 years).
- Provide sex-specific equations; race/ethnicity is not a variable that added predictive value to the equations and provides estimates adjusted for competing risk of non-CVD death.
- Provide a base model for risk prediction that includes commonly available risk factor measures: age, sex, blood pressure, total and HDL-C, diabetes status, tobacco use, kidney function (eGFR), statin use, and antihypertensive medication use (and BMI for heart failure prediction).
- Provide optional models with additional inputs, if known/measured, of hemoglobin A1c (to capture glycemic status), urinary albumin/creatinine ratio (for proteinuria and CKD), and zip code (to represent social deprivation index and acknowledge social determinants of cardiovascular risk). These factors are not necessary to generate risk estimates, but they may enhance risk prediction if available.
- Predict 10-year and 30-year outcomes.
- Predict risk for hard ASCVD† (relevant for LLT decisions), HF, and total CVD (ASCVD plus HF; relevant for blood pressure-lowering therapy decisions).
- Demonstrate similar risk discrimination (C statistics) as the pooled cohort equations for prediction of ASCVD events.
- Provide significantly and substantially more accurate risk estimates (improved calibration) for ASCVD than the pooled cohort equations, overall and in all demographic subgroups. In general, risk estimates from PREVENT-ASCVD equations tend to be 40% to 50% lower than 10-year risk estimates from the pooled cohort equations for the same risk factor profile.
* For the purposes of risk assessment in decision-making for LLT, the PREVENT-ASCVD equations version should be used to predict hard ASCVD outcomes and assist the patient-clinician risk/benefit discussion.

Figure 4. Logic for Defining the Absolute Estimated 10-Year ASCVD Risk for Consideration of LLT at ≥3% in Primary Prevention
The graphs plot the number-needed-to-treat to prevent 1
ASCVD event (NNT-benefit; y-axis) as a function of the observed 10-year
ASCVD event rate (x-axis) from primary prevention RCTs of
statin therapy. The red curves show the number-needed-to-treat to prevent 1
ASCVD event (NNT-benefit) with initiation of (A) moderate-intensity or (B) high-intensity
statin, assuming a 35%
RRR with moderate-intensity and 45%
RRR with high-intensity
statin, as has been observed in meta-regression of
statin trials. The horizontal black lines represent the number-needed-to-treat to cause 1 case of incident diabetes (NND) over 10 years with (A) moderate-intensity or (B) high-intensity
statin. The risk of incident diabetes is higher for high-intensity than lower-intensity statins. Individuals with baseline normoglycemia rarely develop elevations in glucose sufficient to cause a new diagnosis of diabetes. Individuals who develop
statin-attributed diabetes almost universally have documented prediabetes and are already near the threshold for diagnosis of diabetes.
The points where the red curves and the horizontal black lines cross (blue circle; ~3% 10-year event rates for moderate-intensity and ~7% for high-intensity
statin) represent the points at which the NNT-benefit and the NND are equal. Therefore, at risk levels higher than indicated by the dashed lines, there is expected net clinical benefit (potential benefit>potential harm) for initiation of
LLT in primary prevention.
Given that the PREVENT-ASCVD equations accurately predict ASCVD risk, the threshold for consideration of LLT in primary prevention was set at a 10-year PREVENT-ASCVD 10-year risk estimate of ≥3%.

Table 12. Crosswalk Between 10-Year Risk ASCVD Estimates From PCE and PREVENT-ASCVD Equations
* The PREVENT-ASCVD equations generally provide 10-year risk estimates that are 40% to 50% lower than the PCE estimates because the PCE calculator often overestimated the risk for adults.
ASCVD denotes atherosclerotic cardiovascular disease; and PCE, pooled cohort equations.

4.2.3.3. Risk Enhancers
1. In adults without ASCVD with a borderline 10-year ASCVD risk estimate (3% to <5%) by the PREVENT-ASCVD equations, consideration of risk enhancers is reasonable to personalize risk assessment and the potential benefit of initiating LLT as an adjunct to lifestyle management to reduce ASCVD risk (Table 13). ( 2a, B-NR )
2. In adults without
ASCVD with a borderline 10-year
ASCVD risk estimate (3% to <5%) by the
PREVENT-
ASCVD equations, if high-sensitivity C-reactive protein (
hsCRP) is measured and is ≥2 mg/L on 2 successive occasions with no identifiable underlying cause of
hsCRP elevation, high-intensity
statin therapy can be useful to reduce the risk of
ASCVD events.
( 2a, B-R ) Table 13. Risk-Enhancers
Risk-Enhancers
- History of premature ASCVD in a parent or sibling (onset age <55 y for men, <65 y for women)
- Higher risk ancestry (eg, South Asian, Filipino)
- High polygenic risk (if measured) (Section 4.2.3.5, “Polygenic Risk Scores”)
- Chronic inflammatory diseases (eg, systemic lupus, rheumatoid arthritis, advanced psoriasis, inflammatory arthritis)
- Lp(a) ≥125 nmol/L or ≥50 mg/dL
- hsCRP ≥2 mg/L on >1 occasion (if measured)
- TG persistently ≥175 mg/dL (2 mmol/L) (if nonfasting) and ≥150 mg/dL (1.7 mmol/L) (if fasting)
- CKM syndrome
- LDL-C persistently ≥160–189 mg/dL (4.1–4.9 mmol/L), non–HDL-C≥190–219 mg/dL or apoB ≥120 mg/dL*
- Reproductive risk markers (premature menopause, preeclampsia, gestational diabetes, gestational hypertension, preterm delivery; Section 4.2.3.4, “Reproductive Risk Marker”)
Note that all available information should be included in risk estimates derived from the PREVENT-ASCVD equations, including albuminuria, HbA1c, and zip code for assessment of neighborhood-level social determinants of health. Given the recent publication of the PREVENT-ASCVD equations, it remains to be demonstrated for most risk-enhancers that risk is incremental to the PREVENT-ASCVD equations.
* Although LDL-C is not included in the PREVENT-ASCVD equations (total cholesterol and HDL-C are included), it is included here because persistent elevation of LDL-C may be a useful factor to include in risk-benefit discussions about LDL-C–lowering therapy, given that it is the target of that therapy. See Section 4.2.3.4, “Reproductive Risk Marker,” for more detail regarding reproductive risk factors.
ApoB indicates apolipoprotein B; ASCVD, atherosclerotic cardiovascular disease; CKM, cardiovascular-kidney-metabolic; HbA1c, hemoglobin A1c; HDL-C, high-density lipoprotein-cholesterol; hsCRP, high-sensitivity C-reactive protein; LDL-C, low-density lipoprotein-cholesterol; Lp(a), lipoprotein (a); and TG, triglycerides.

4.2.3.4. Reproductive Risk Markers
1. In adults without ASCVD, consideration of reproductive risk markers, such as early menopause (<45 years) and history of adverse pregnancy outcomes (gestational hypertension, preeclampsia, gestational diabetes, preterm delivery) is reasonable to personalize ASCVD risk assessment when considering the potential benefit of initiating LLT as an adjunct to lifestyle management for primary ASCVD prevention. ( 2a, B-NR )
Table 14. Reproductive Risk Markers Associated With ASCVD Events
Adverse Pregnancy Outcomes* That Have a Stronger Association With ASCVD Events
- Hypertensive disorders of pregnancy (preeclampsia, gestational hypertension)
- Gestational diabetes
- Small-for-gestational age (birthweight below the 10th percentile)
- Preterm delivery (before 37 weeks' gestation)
- Recurrent spontaneous pregnancy loss
Other Reproductive Risk Markers
- Early menarche (<10 y old)
- Early menopause (<45 y old), especially premature menopause (<40 y old)
- Polycystic ovarian syndrome and irregular menses
* See reference for a full list of Adverse Pregnancy Outcomes.
ASCVD indicates atherosclerotic cardiovascular disease; and y, years.
4.2.3.5. Polygenic Risk Scores
4.2.3.6. Selective Imaging of Subclinical Atherosclerosis (Men ≥40 or Women ≥45 Years)
1. In adults at intermediate risk and select adults at borderline risk with no prior ASCVD, if the decision regarding LLT remains uncertain, a CAC score should be used for further risk stratification and to guide the decision to withhold, postpone, or initiate therapy. ( 1, B-R )
2. In adults at intermediate risk or select adults at borderline risk who undergo CAC testing, if the CAC score is 0 Agatston units (AU), and there is preference to avoid LLT and focus on lifestyle management, and no higher risk conditions (FH or severe hypercholesterolemia >190 mg/dL, diabetes and age >40 years, current cigarette smoking, strong family history of premature ASCVD) are present, it is reasonable to defer therapy and reassess with repeat CAC testing in 3 to 7 years to personalize management. ( 2a, B-NR )
3. In adults at intermediate risk and select adults at borderline risk, if the CAC score is >0 AU, it is recommended to initiate LLT, particularly if the CAC score is ≥100 AU or ≥75th standardized percentile to reduce ASCVD risk. ( 1, B-NR )
4. In adults at intermediate or high risk with no prior ASCVD, if there is uncertainty about the intensity of LLT, a CAC score can be useful to refine treatment goals and decide whether to intensify LLT. ( 2a, B-NR )
5. In adults with no prior ASCVD, if incidental CAC is identified on noncardiac computed tomography (CT) scans (eg, by visual estimation or a validated artificial-intelligence based algorithm), the presence of coronary atherosclerosis should be considered during decision-making about initiation or intensification of LLT to reduce ASCVD risk. ( 1, B-NR )
6. In adults with no prior ASCVD who are likely to have a high burden of noncalcified plaque (eg, inflammatory disorders, persons living with HIV, and diabetes), selective use of coronary CT selective use of coronary CT selective use of coronary CT angiography (CCTA) may be useful to inform risk assessment and guide decisions regarding treatment intensity of LLT. ( 2b, B-NR )
4.2.3.7. Primary Prevention in Adults 30 to 79 Years With LDL-C Levels 70 to 189 mg/dL (1.8–4.9 mmol/L)
1. In adults being assessed for primary prevention of ASCVD, health behavior recommendations should be provided in addition to a benefit-risk discussion for consideration of LLT1–4 (Section 4.1.2, “Dietary Approaches in Dyslipidemia”). ( 1, A )
Low (<3%) Estimated 10-Year ASCVD Risk
2. In adults aged 30 to 59 years, at low (<3%) 10-year estimated risk for ASCVD who have an LDL-C <160 mg/dL (4.1 mmol/L) and a 30-year risk estimate of <10%, counseling on health behaviors is recommended to reduce LDL-C and risk for ASCVD. ( 1, A )
3. In adults aged 30 to 59 years, at low (<3%) 10-year estimated risk for ASCVD but with an
LDL-C of 160 to 189 mg/dL (4.1–4.9 mmol/L) or a 30-year
ASCVD risk ≥10% (for those aged 30-59 years), a moderate-intensity
statin is reasonable to reduce cumulative exposure to atherogenic lipoproteins.
( 2a, C-LD )
Borderline (3% to <5%) and Intermediate (5% to <10%) 10-Year ASCVD Risk
4. In adults at borderline (3% to <5%) 10-year estimated risk for ASCVD in whom a decision is made to initiate
statin therapy for primary prevention, a moderate-intensity
statin is reasonable to achieve ≥30 to 49%
LDL-C reduction and to reduce
ASCVD risk.
( 2a, A ) 5. In adults at intermediate (5% to <10%) 10-year estimated risk for ASCVD, at least a moderate-intensity
statin is recommended to achieve ≥30 to 49%
LDL-C reduction and to reduce
ASCVD risk; for those in the higher end of this risk range, a high-intensity
statin is beneficial to further reduce
LDL-C by ≥50% and reduce
ASCVD risk.
( 1, A ) 6. In adults at borderline (3% to <5%) or intermediate (5% to <10%) 10-year estimated risk for ASCVD in whom
statin therapy is initiated, it is reasonable to treat to a goal of
LDL-C <100 mg/dL (2.6 mmol/L) and non–HDL-C <130 mg/dL (3.4 mmol/L) to reduce
ASCVD risk.
( 2a, B-NR )
High (≥10%) 10-Year Estimated ASCVD Risk
7. In adults at high (≥10%) 10-year risk for
ASCVD in whom
LLT is initiated for primary prevention, high-intensity
statin therapy is recommended to achieve an
LDL-C reduction of ≥50% to reduce the risk of
ASCVD.
( 1, A ) 8. In adults at high (≥10%) 10-year risk for
ASCVD in whom a decision to initiate
statin therapy is made, it is reasonable to treat to a goal of
LDL-C <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL (2.6 mmol/L) to reduce
ASCVD risk.
( 2a, B-R ) 9. In adults at high (≥10%) 10-year estimated risk for
ASCVD on maximally tolerated
statin, it is reasonable to add
ezetimibe if a goal
LDL-C <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL (2.6 mmol/L) is not achieved.
( 2a, B-R ) 10. In adults at high (≥10%) 10-year estimated risk for
ASCVD on maximally tolerated
statin with or without
ezetimibe, it may be reasonable to add a PCSK9 mAb or
bempedoic acid if a goal
LDL-C <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL (2.6 mmol/L) is not achieved to lower
LDL-C and reduce
ASCVD risk.
( 2b, B-NR )
Special Considerations in Primary Prevention
11. In individuals with a life expectancy of <1 year, it may be reasonable to discontinue LLT that was prescribed for primary prevention purposes to avoid unnecessary medication use or adverse medication effects. ( 2b, B-R )
12. In adults with a baseline untreated LDL-C <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL (2.6 mmol/L) and without additional ASCVD risk factors, initiation of LLT for primary prevention is unlikely to reduce ASCVD risk. ( 3 - No Benefit, B-NR )

4.2.4.1. Role of Risk Assessment in Heterozygous Familial Hypercholesterolemia (HeFH)
1. In adults with HeFH, FH-specific risk scores may be useful in predicting short-term ASCVD risk. ( 2b, B-NR )
2. In individuals with HeFH, standard risk assessment tools developed for the general population should not be used to calculate 10-year or 30-year ASCVD risk. ( 3 - Harm, C-EO )
4.2.4.2. Genetic Testing for Familial Hypercholesterolemia
1. In adults with possible, probable, or definite FH, panel-based genetic testing for pathogenic/likely pathogenic rare variants for FH is beneficial to identify individuals at highest risk of cardiovascular events and to facilitate cascade screening. ( 1, B-NR )
2. In adults with severe hypercholesterolemia with an LDL-C ≥190 mg/dL (4.9 mmol/L) without an identified secondary cause, panel-based genetic testing for pathogenic/likely pathogenic rare variants for FH can be useful to identify those with FH who are at higher risk of ASCVD events. ( 2a, B-NR )
3. In adults with an elevated LDL-C of 160 to 189 mg/dL (4.1–4.9 mmol/L) without an identified secondary cause, panel-based genetic testing for pathogenic/likely pathogenic rare variants for FH may be considered to identify those with FH who are at higher risk of events. ( 2b, B-NR )
4.2.4.3. Severe Hypercholesterolemia With LDL-C ≥190 mg/dL (4.9 mmol/L)*
1. In adults with severe hypercholesterolemia with an LDL-C ≥190 mg/dL (4.9 mmol/L)*, secondary causes of dyslipidemia should be excluded and addressed to reduce LDL-C (Table 16). ( 1, B-NR )
* Severe hypercholesterolemia with LDL-C >190 mg/dL, non–HDL-C >220 mg/dL, and/or apoB >140 mg/dL.
2. In adults with severe hypercholesterolemia with an
LDL-C ≥190 mg/dL (4.9 mmol/L)
*, treatment with maximally tolerated
statin therapy is recommended to lower
LDL-C and reduce
ASCVD risk.

LDL-C <100 mg/dL (2.6 mmol/L) and a non–HDL-C goal of <130 mg/dL (3.4 mmol/L) and to reduce
ASCVD risk.
( 1, B-NR ) * Severe hypercholesterolemia with LDL-C >190 mg/dL, non–HDL-C >220 mg/dL, and/or apoB >140 mg/dL.

bempedoic acid to achieve a goal of
LDL-C <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL (2.6 mmol/L) is recommended to lower
LDL-C and reduce
ASCVD risk.
( 1, B-R ) * Severe hypercholesterolemia with LDL-C >190 mg/dL, non–HDL-C >220 mg/dL, and/or apoB >140 mg/dL.

* and clinical
ASCVD who are on maximally tolerated
statin therapy, the addition of
ezetimibe, a PCSK9 mAb, and/or
bempedoic acid is recommended to achieve a goal of
LDL-C <55 mg/dL (1.4 mmol/L) and non–HDL-C <85 mg/dL (2.2 mmol/L) to lower
LDL-C and reduce
ASCVD risk.
( 1, B-R ) * Severe hypercholesterolemia with LDL-C >190 mg/dL, non–HDL-C >220 mg/dL, and/or apoB >140 mg/dL.
Inclisiran in Severe Hypercholesterolemia
6. In adults with severe hypercholesterolemia, with or without clinical
ASCVD, and
LDL-C ≥100 mg/dL (2.6 mmol/L) despite maximally tolerated
statin with or without
ezetimibe therapy, treatment with inclisiran14 is reasonable to lower

4.2.5. Diabetes in Adults Without Established ASCVD
1. In adults 40 to 75 years of age with diabetes and without clinical
ASCVD, moderate-intensity
statin therapy is indicated to achieve a ≥30% to 49% reduction in
LDL-C and a goal of
LDL-C <100 mg/dL (2.6 mmol/L) and non–HDL-C <130 mg/dL (3.4 mmol/L) to reduce
ASCVD risk.
( 1, A ) 2. In adults with diabetes who have
statin-attributed side effects, initiation of
ezetimibe and/or
bempedoic acid or a PCSK9 mAb is recommended to lower
LDL-C and reduce
ASCVD risk.
( 1, B-R ) 3. In adults 40 to 75 years of age with diabetes who have multiple
ASCVD risk factors, it is reasonable to prescribe high-intensity
statin therapy to achieve a ≥50% reduction in
LDL-C and a goal of
LDL-C <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL (2.6 mmol/L) to reduce
ASCVD risk.
( 2a, B-R ) 4. In adults with diabetes without
ASCVD but with additional
ASCVD risk factor(s)
* on a
statin with an
LDL-C <100 mg/dL (2.6 mmol/L) and elevated fasting
TG (150–499 mg/dL [1.7–5.6 mmol/L]), the addition of
IPE may be considered to reduce
ASCVD risk.
( 2b, B-R ) * As per REDUCE-IT inclusion criteria, high-risk features include men ≥55 years or women ≥65 years, cigarette smoking or stopped smoking within 3 months; hypertension (blood pressure ≥140 mm Hg systolic or ≥90 mm Hg diastolic) or on antihypertensive medication; high-density lipoprotein-cholesterol ≤40 mg/dL for men or ≤50 mg/dL for women; highsensitivity C-reactive protein >3.0 mg/L (if measured); renal dysfunction: creatinine clearance >30 and <60 mL/min; retinopathy; albuminuria (≥30 μg of albumin mg creatinine); anklebrachial index <0.9 without symptoms of intermittent claudication (if measured).
5. In adults with diabetes and 10-year

† In adults with diabetes who have
statin-attributed side effects, initiation of
ezetimibe and/or
bempedoic acid and/or a PCSK mAb is recommended to lower
LDL-C and reduce
ASCVD risk.
4.2.6. Secondary ASCVD Prevention
Clinical ASCVD Not at Very High Risk*
1. In adults with clinical
ASCVD who are not at very high risk (Figure 10), high-intensity
statin therapy should be initiated to achieve a ≥50% reduction in
LDL-C and a goal of
LDL-C <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL to reduce the risk of recurrent
ASCVD events.
( 1, A ) 2. In adults with clinical
ASCVD who are not at very high risk and on maximally tolerated
statin therapy, it is reasonable to add
ezetimibe, a PCSK9 mAb, or
bempedoic acid (selection depending on degree of
LDL-C lowering needed and patient preference) to achieve a goal of
LDL-C <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL to reduce the risk of
ASCVD events.
( 2a, B-R ) 3. In adults with clinical
ASCVD who are not at very high risk and on maximally tolerated
statin therapy, it is reasonable to add
ezetimibe, a PCSK9 mAb, or
bempedoic acid (selection based on the degree of
LDL-C lowering needed and patient preference) to achieve a goal
LDL-C <55 mg/dL (1.4 mmol/L) and non–HDL-C <85 mg/dL (2.2 mmol/L) and to reduce the risk of
ASCVD events.
( 2a, B-R ) * The majority of patients with clinical
ASCVD are likely to be at very high risk. Very high risk includes a history of multiple major
ASCVD events (
ACS within past 12 months, history of
MI [other than
ACS above] history of ischemic stroke, symptomatic
PAD) or 1 major
ASCVD event and multiple high-risk conditions (age >65 years of age, coronary artery revascularization, current smoker, diabetes, history of heart failure, hypertension,
LDL-C >100 mg/dL despite maximally tolerated
statin +
ezetimibe).
Clinical ASCVD at Very High Risk*
4. In adults with clinical
ASCVD* who are at very high risk (Figure 10 and Figure 11), high-intensity
statin therapy should be initiated to achieve a ≥50% reduction in
LDL-C and a goal
LDL-C <55 mg/dL (1.4 mmol/L) and non–HDL-C <85 mg/dL (2.2 mmol/L) and to reduce the risk of
ASCVD events.
( 1, A ) * The majority of patients with clinical
ASCVD are likely to be at very high risk. Very high risk includes a history of multiple major
ASCVD events (
ACS within past 12 months, history of
MI [other than
ACS above] history of ischemic stroke, symptomatic
PAD) or 1 major
ASCVD event and multiple high-risk conditions (age >65 years of age, coronary artery revascularization, current smoker, diabetes, history of heart failure, hypertension,
LDL-C >100 mg/dL despite maximally tolerated
statin +
ezetimibe).
5. In adults with clinical
ASCVD who are at very high risk and on maximally tolerated
statin therapy,
ezetimibe and/ or a PCSK9 mAb should be added (selected based on the degree of
LDL-C lowering needed and patient preference) to achieve a goal of
LDL-C <55 mg/dL (1.4 mmol/L) and non–HDL-C <85 mg/dL (2.2 mmol/L) to reduce risk of
ASCVD events.
( 1, A ) 6. In adults with clinical
ASCVD who are at very high risk on maximally tolerated
statin therapy, it is reasonable to add
bempedoic acid, with or without
ezetimibe and/or PCSK9 mAb, to reach an
LDL-C goal <55 mg/dL (1.4 mmol/L) and non–HDL-C <85 mg/dL (2.2 mmol/L) to reduce the risk of
ASCVD events.
( 2a, B-R ) 7. In adults with clinical
ASCVD who are at very high risk and on maximally tolerated
statin therapy with or without
ezetimibe, it is reasonable to add inclisiran
† in those unable to tolerate or obtain evolocumab or alirocumab or have a strong preference for less frequent dosing to achieve an
LDL-C goal <55 mg/dL (1.4 mmol/L) and non–HDL-C <85 mg/dL (2.2 mmol/L).
( 2a, B-R ) † Cardiovascular outcomes trials are not completed with inclisiran. It is approved for LDL-C lowering only and is considered a second-line PCSK9i at this time.
Heart Failure With Reduced Ejection Fraction (HFrEF) Due to ASCVD
8. In adults with
HFrEF attributable to ischemic heart disease who have a reasonable life expectancy (3–5 years) and are not already on a
statin because of
ASCVD, it may be reasonable to consider initiation of moderate-intensity
statin therapy to reduce the occurrence of
ASCVD events.

4.2.7. Management of Adults With Subclinical Coronary Atherosclerosis (Men ≥40 or Women ≥45 Years)
1. In adults with a
CAC score of ≥1000
AU, treatment with
LDL-C–lowering therapies with consideration of
statin therapy as first line is recommended to achieve a ≥50% reduction in
LDL-C and a goal of
LDL-C <55 mg/dL (1.4 mmol/L) and non–HDL-C <85 mg/dL (2.2 mmol/L).
( 1, B-NR ) 2. In adults with a
CAC score of ≥300 to 999
AU, treatment with
LDL-C–lowering therapies, with consideration of
statin therapy as first line, is recommended to achieve a ≥50% lowering in
LDL-C and a goal
LDL-C <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL (2.6 mmol/L).
( 1, B-R ) 3. In adults with a
CAC score of ≥100 to 299
AU or ≥75th standardized percentile, treatment with
LLT, with consideration of
statin therapy as first-line therapy, is recommended to achieve a ≥50% reduction in
LDL-C and a goal
LDL-C <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL (2.6 mmol/L).
( 1, B-R ) 4. In adults with a
CAC score of 1 to 99
AU and <75th standardized percentile, or with an incidental finding of mild
CAC on noncardiac
CT scan, treatment with moderate-intensity
statin therapy is reasonable to achieve a ≥30% to 49% reduction in
LDL-C and a goal of
LDL-C <100 mg/dL (2.6 mmol/L) and non–HDL-C <130 mg/dL (3.4 mmol/L).
( 2a, B-R ) 5. In adults with a
CAC score of ≥300 to 999
AU, it is reasonable to intensify therapy by increasing the intensity of
statin therapy or, if needed, adding
ezetimibe, a PCSK9 mAb, or
bempedoic acid to achieve a goal of
LDL-C <55 mg/dL (1.4 mmol/L) and non–HDL-C <85 mg/dL (2.2 mmol/L).
( 2a, B-NR ) 6. Among adults with no prior
ASCVD who have moderate-to-severe incidental coronary atherosclerosis identified on noncardiac
CT scans (eg, by visual estimation or a validated artificial intelligence-based algorithm), it is reasonable to initiate high-intensity
statin therapy to achieve at least a ≥50% reduction in
LDL-C and a goal of
LDL-C <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL (2.6 mmol/L); if mild incidental
CAC, moderate-intensity
statin therapy is reasonable to achieve a ≥30% to 49% reduction in
LDL-C and a goal of
LDL-C <100 mg/dL (2.6 mmol/L) and non–HDL-C goal <130 mg/dL.
( 2a, B-NR )
4.2.8. Considerations in Patient Management
4.2.8.1. Children and Adolescents
1. In children and adolescents with lipid abnormalities, lifestyle management is recommended to improve LDL-C, TG, and non–HDL-C. ( 1, B-R )
2. In children and adolescents ≥8 years of age with an
LDL-C level persistently ≥160 mg/dL (4.1 mmol/L) and a presentation consistent with
FH who do not respond sufficiently after 3 to 6 months of lifestyle management, initiation of
statin and other
LLT as necessary is recommended to lower
LDL-C.
* ( 1, B-R ) * Children with HoFH required specialized consideration, including aggressive LLT at the time of diagnosis, including in infancy (Section 4.2.4.4, “Severe Hypercholesterolemia with Clinical or Genetic Confirmation of Homozygous Familial Hypercholesterolemia [HoFH]”).
3. In children and adolescents with a clinical presentation consistent with FH, panel-based genetic testing for pathogenic/likely pathogenic rare variants for FH can be useful to guide diagnosis, cascade testing, and treatment. ( 2a, B-NR )
Table 18. Normal and Elevated Lipid Values in Childhood*
* Values for plasma lipid and lipoprotein levels are from the National Cholesterol Education Program Expert Panel on Cholesterol Levels in Children; non–HDL-C values equivalent to LDL-C are taken from the Bogalusa Heart Study. The cutpoints for high and borderline high represent approximately the 95th and 75th percentiles, respectively. Low cutpoints for HDL-C represent approximately the 10th percentile.
Values given are in mg/dL. To convert to SI units, divide the results for TC, LDL-C, HDL-C, and non–HDL-C by 38.6; for TG, divide by 88.6.

HeFH, heterozygous familial hypercholesterolemia; HoFH, homozygous familial hypercholesterolemia; IV, intravenous; PO, per os; and SQ, subcutaneous.
4.2.8.2. Young Adults Ages 18 to 39 Years of Age
1. In young adults (18–39 years of age), dietary, physical activity, and weight optimization recommendations should be provided to reduce cumulative atherogenic lipid exposure and lifetime ASCVD risk. ( 1, B-NR )
4.2.8.3. Older Adults
1. In older adults, the benefit-risk discussion should include patient priorities, functional status, multimorbidity, frailty, polypharmacy, and life expectancy, and should not be based solely on chronological age when considering the decision to discontinue LLT. ( 1, C-EO )
2. In adults aged >75 years with an estimated life expectancy of at least 2.5 years, it may be reasonable to initiate moderate-intensity
statin therapy after a clinician-patient discussion of potential benefits and risks to reduce
ASCVD risk.
( 2b, B-NR ) 3. In patients with a life expectancy of <1 year, it may be reasonable to discontinue LDL-lowering therapy to avoid unnecessary medication use or adverse medication effects. ( 2b, B-R )
4. In adults aged >75 years with an estimated life expectancy of at least 2.5 years, and for whom the decision regarding LLT is uncertain, it may be reasonable to measure CAC to reclassify those with minimal (1-10) or no CAC to avoid LLT. ( 2b, B-NR )
4.2.8.4. Management of Dyslipidemia in Persons Planning Pregnancy, During Pregnancy, or While Lactating
1. Persons of childbearing age with hypercholesterolemia who are not at high risk for
ASCVD and plan to become pregnant should stop
statin therapy 1 to 2 months before attempting to become pregnant or as soon as pregnancy is discovered to avoid uncertain risks to the fetus.
( 1, C-LD ) 2. In pregnant or lactating individuals with HoFH, it is reasonable to undergo lipoprotein apheresis to lower LDL-C and reduce ASCVD risk. ( 2a, B-NR )
3. In pregnant individuals with severe fasting hypertriglyceridemia (TG ≥500 mg/dL [5.7 mmol/L]), the use of fibrates (after the first trimester) or high-dose omega-3 ethyl esters is reasonable as an adjunct to lifestyle management to lower TG levels and reduce the risk of pancreatitis. ( 2a, B-NR )
4. In pregnant or lactating individuals with hypercholesterolemia but without hypertriglyceridemia, the use of bile acid sequestrants is reasonable to lower LDL-C. ( 2a, C-EO )
5. In pregnant individuals with
FH or a history of clinical
ASCVD, it may be reasonable to continue
statin therapy to lower
LDL-C and
ASCVD risk following an individualized benefit-risk discussion.
* ( 2b, C-LD ) * The use of a hydrophilic
statin, such as pravastatin, should be considered if the benefit of continued
statin therapy is deemed greater than potential risk based on results from available clinical trials.

4.2.8.5. Considerations Based on Ancestry
Table 21. Considerations According to Ancestry Groups
Observed Higher Risk in Demographic Groups
- South Asian ancestry is a high-risk demographic group and considered a risk-enhancer.
- Increased prevalence of diabetes at lower BMI and waist circumferences across Asian populations.
- Increased CKM syndrome risk factors among Filipino American individuals, including hypertension, hyperlipidemia, and obesity.
Variation in Lipid Measures
- Higher levels of Lp(a) are found in non-Hispanic Black individuals, but associated increase in CVD relative risk is similar to other groups.
- Elevated Lp(a) is associated with a higher population-attributed risk for MI among South Asian and Latin American people.
- Baseline CK levels are higher in non-Hispanic Black individuals but may not portend greater risk for statin-associated adverse events.
Statin Sensitivity
- Some individuals of Chinese, Japanese, or Korean ancestry have been observed to have higher plasma concentrations of rosuvastatin, resulting in heightened sensitivity, and may benefit from starting rosuvastatin therapy at a lower dose.
BMI indicates body mass index; CK, creatine kinase; CVD, cardiovascular disease; Lp(a), lipoprotein (a); and MI, myocardial infarction.
4.2.8.6. Adults With Heart Failure
1. In adults with HFrEF who do not have clinical ASCVD or another indication for LLT, initiation of LLT is not recommended to reduce clinical events or mortality. ( 3 - No Benefit, A )
4.2.8.7. Adults With Chronic Inflammatory Diseases (CID)
4.2.8.8. Adults With Chronic Kidney Disease – Stage 3 or Higher
1. In adults 40 to 75 years of age with
CKD stage 3 or higher and an
LDL-C of 70 to 189 mg/dL (1.8–4.9 mmol/L), moderate-intensity
statin therapy or moderate-intensity
statin combined with
ezetimibe is recommended to reduce
ASCVD risk.
( 1, B-R ) 2. In adults with
CKD stage 3 or higher and clinical
ASCVD,
LLT with high-intensity
statin therapy, with or without
ezetimibe and/or a PCSK9 mAb, is recommended to achieve a ≥50% reduction in
LDL-C levels and a goal of
LDL-C <55 mg/dL (1.4 mmol/L) and non–HDL-C <85 mg/dL (2.2 mmol/L) to reduce
ASCVD risk.
( 1, B-R ) 3. In adults with
CKD who require maintenance hemodialysis, it may be reasonable to continue
statin therapy to reduce the risk of
ASCVD events. Treatment decisions should be individualized with consideration of expected survival, other comorbidities, and severity of
ASCVD.

4.2.8.9. Persons Living With Human Immunodeficiency Virus (HIV)
1. In people living with
HIV aged 40 to 75 on stable combination antiretroviral therapy,
statin therapy is recommended to reduce risk of a first
ASCVD event and reduce the rate of coronary atherosclerosis progression.
( 1, B-R )
4.2.8.10. Adults With Cancer or History of Cancer
1. Adult cancer survivors with life expectancy of at least 2 years who otherwise qualify for LLT should be treated similarly to people without history of cancer to reduce the risk of ASCVD events. ( 1, B-NR )
2. In adults with active cancer currently on
statin therapy, treatment should be continued to reduce
ASCVD risk unless there is concern for a specific drug interaction or life expectancy is <1 year.
( 1, B-NR ) 3. In adults with active cancer, initiation of
statin therapy may be considered to prevent anthracycline-induced cardiotoxicity.
( 2b, B-R )
4.2.9. Management of Hypertriglyceridemia
1. In adults with persistently elevated TG levels ≥150 mg/dL (1.7 mmol/L), after evaluation and management of secondary causes, lifestyle management (consuming a diet that consists of low added sugars, as well as reduced alcohol and saturated fat intake, routine exercise, and weight loss of 5%–10% of body weight if overweight or obese) is recommended as a first-line approach to reduce TG levels (Figure 2). ( 1, B-NR )
2. In adults with clinical
ASCVD and
LDL-C ≥55 mg/dL (1.4 mmol/L) and non–HDL-C ≥85 mg/dL on maximally tolerated
statin with persistently elevated
TG levels ≥150 to 999 mg/dL (1.7–11.3 mmol/L), intensification of
LDL-C–lowering therapy is recommended to reduce
ASCVD risk.
( 1, B-R ) 3. In adults with FCS and fasting TG ≥1000 mg/dL (11.3 mmol/L), olezarsen is recommended as an adjunct to diet to lower TG levels and reduce the risk of pancreatitis. ( 1, B-R )
4. In adults ≥50 years of age with clinical
ASCVD or with diabetes and ≥1
ASCVD risk factors, with persistently elevated
TG levels ≥150 to 499 mg/dL (1.7–5.6 mmol/L), and
LDL-C <100 mg/dL (2.6 mmol/L) on maximally tolerated
statin, the addition of
IPE may be reasonable to lower
ASCVD risk. (See Figure 9 in Section 4.2.5, “ Diabetes in Adults Without Established
ASCVD.”)
( 2b, B-R ) 5. In adults aged 40 to 75 years without a history of
ASCVD or diabetes who have persistently elevated
TG levels ≥150 to 499 mg/dL (≥1.7–5.6 mmol/L), it is recommended to estimate 10-year
ASCVD risk by the
PREVENT-
ASCVD equations to guide the benefit-risk discussion regarding further optimization of diet and lifestyle management as well as the potential initiation of
statin therapy to reduce
ASCVD risk (Figure 11.)
( 1, A ) 6. In adults with severe hypertriglyceridemia (persistently elevated TG levels ≥500–999 mg/dL [5.7 mmol/L] and especially with TG levels ≥1000 mg/dL (11.3 mmol/L) despite dietary intervention, the use of fibric acid derivatives or prescription omega-3 fatty acids is reasonable to lower TG levels and reduce the risk of pancreatitis (Figure 11.) ( 2a, B-NR )
7. In adults with hypertriglyceridemia (TG ≥150 mg/dL), measurement of non–HDL-C or apoB is preferred over LDL-C to guide clinical decision- making. ( 2a, B-NR )

4.2.10. Approach to Patients With Elevated Lp(a)
1. In all individuals with elevated Lp(a) (≥125 nmol/L or ≥50 mg/dL), optimal early control of modifiable cardiovascular risk factors is recommended to reduce ASCVD risk. ( 1, B-NR )
2. In individuals with clinical
ASCVD and elevated
Lp(a) who have not achieved
LDL-C and non–HDL-C treatment goals on maximally tolerated
statin therapy, the addition of a PCSK9 mAb with proven cardiovascular benefit is recommended to achieve treatment goals and reduce
ASCVD risk.
( 1, B-R )
4.2.11. Management of Statin-Attributed Muscle Symptoms
1. In adults with
statin-attributed muscle symptoms, assessment should include evaluation for secondary causes (Table 24), and in those with severe myalgias or weakness, objective clinical measures of muscle strength and measurement of
CK are recommended to assess severity of the condition.
( 1, C-LD ) 2. In adults with
statin-attributed muscle symptoms, the clinician-patient discussion should acknowledge patient side effect concerns, inform the patient of the heightened
ASCVD risk associated with
statin discontinuation, and provide alternative treatment options to reduce
ASCVD risk.
( 1, B-R ) 3. In adults with clinical
ASCVD who experience
statin-attributed muscle symptoms on the recommended intensity of
statin therapy (secondary causes excluded) and are unable to achieve recommended treatment goals, use of a reduced
statin dose (if tolerable) and the addition of
bempedoic acid,
ezetimibe, or a PCSK9 mAb, alone or in combination, are recommended to lower
LDL-C and reduce
ASCVD risk.
( 1, B-R ) 4. In adults without a history of clinical
ASCVD who experience
statin-attributed muscle symptoms on the recommended intensity of
statin therapy (secondary causes excluded) and are at high
ASCVD risk based on a
PREVENT-
ASCVD equation of ≥10% or a
CAC score ≥300
AU, or women >65 years of age or men >60 years of age with diabetes, the addition of
bempedoic acid and/or
ezetimibe is/are indicated to lower
LDL-C to <70 mg/dL (1.8 mmol/L) and non–HDL-C <100 mg/dL (2.6 mmol/L) and to reduce
ASCVD risk.
( 1, B-R ) 5. In adults without a history of clinical
ASCVD who experience
statin-attributed muscle symptoms on the recommended intensity of
statin therapy (secondary causes excluded) and are at high
ASCVD risk based on a
PREVENT-
ASCVD equation of ≥10% or a
CAC score ≥300
AU or diabetes and are unable to achieve recommended treatment goals, the addition of a PCSK9 mAb is reasonable to lower
LDL-C.
( 2a, B-R ) 6. In adults with clinical
ASCVD who experience
statin-attributed muscles symptoms (secondary causes excluded) and are unable to achieve recommended treatment goals on
bempedoic acid with or without
ezetimibe, it is reasonable to add inclisiran in those unable to tolerate or obtain evolocumab or alirocumab or who have a strong preference for less frequent dosing to achieve an
LDL-C goal <55 mg/dL (1.4 mmol/L) and non–HDL-C <85 mg/dL (2.2 mmol/L).
( 2a, B-NR ) 7. In adults without a history of clinical
ASCVD who experience
statin-attributed muscle symptoms on the recommended intensity of
statin therapy (secondary causes excluded) and are at borderline to intermediate
ASCVD risk based on a
PREVENT-
ASCVD equation of 3% to <10%, and in whom the decision to treat with
ezetimibe and/or
bempedoic acid is uncertain, coronary calcium scoring may be reasonable to aid in
ASCVD risk stratification to inform decision-making about add-on therapy to reduce
ASCVD risk.
( 2b, B-R ) 8. In adults without a history of clinical
ASCVD who experience
statin-attributed muscle symptoms on the recommended intensity of
statin therapy (secondary causes excluded) and are at borderline or intermediate
ASCVD risk based on a
PREVENT-
ASCVD equation of 3% to <10%, the addition of
ezetimibe and/or
bempedoic acid may be reasonable to lower
LDL-C to <100 mg/dL (2.6 mmol/L) and non–HDL-C to <130 mg/dL (3.4 mmol/L) and reduce
ASCVD risk.

Complications of Management
5.1. Medication Safety and Therapy-Associated Side Effects
1. In adults with dyslipidemia, an individualized clinician–patient discussion prior to initiating lipid-lowering medication is recommended to review the benefits and risks of pharmacotherapy to promote patient engagement and medication adherence. ( 1, A )
2. In adults with elevated diabetes risk or new-onset diabetes, it is recommended to continue
statin therapy, with added emphasis on adherence, net clinical benefit, and lifestyle management.
( 1, A ) 3. In adults at elevated
ASCVD risk with chronic, stable liver disease (including metabolic dysfunction-associated steatotic liver disease), it is reasonable to treat with
statin therapy to reduce
ASCVD risk.
( 2a, B-R ) 4. In adults on
statin therapy, routine use of coenzyme Q10 is
not recommended to treat or prevent
statin-attributed muscle symptoms.
( 3 - No Benefit, B-R ) 5. In adults on
statin therapy who do not have severe
statin-attributed muscle symptoms, routine measurement of
CK is
not useful to assess safety.
( 3 - No Benefit, A ) 6. In adults treated with
statin therapy who do not have severe symptoms suggestive of hepatotoxicity (ie, jaundice, pruritus, fatigue, nausea and vomiting, abdominal pain), routine measurement of hepatic function is
not useful to assess safety.

statin therapy, a review of concomitant medications and assessment for potential
DDI with other cardiovascular medications is recommended to minimize the risk of
statin-associated adverse events.

Class of Recommendations and Level of Evidence
COR and LOE are determined independently (any COR may be paired with any LOE).
A recommendation with LOE C does not imply that the recommendation is weak. Many important clinical questions addressed in guidelines do not lend themselves to clinical trials. Although RCTs are unavailable, there may be a very clear clinical consensus that a particular test or therapy is useful or effective.
* The outcome or result of the intervention should be specified (an improved clinical outcome or increased diagnostic accuracy or incremental prognostic information).
† For comparative-effectiveness recommendations (COR I and IIa; LOE A and B only), studies that support the use of comparator verbs should involve direct comparisons of the treatments or strategies being evaluated.
‡ The method of assessing quality is evolving, including the application of standardized, widely used, and preferably validated evidence grading tools; and for systematic reviews, the incorporation of an Evidence Review Committee.
COR indicates Class of Recommendation; EO, expert opinion; LD, limited data; LOE, Level of Evidence; NR, nonrandomized; R, randomized; RCT, randomized controlled trial.
