Note:
These estimates may underestimate the 10-year and
lifetime risk for persons from some race/ethnic groups,
especially American Indians, some Asian Americans (e.g., of
south Asian ancestry), and some Hispanics (e.g., Puerto Ricans),
and may overestimate the risk for others, including some
Asian Americans (e.g., of east Asian ancestry) and some
Hispanics (e.g., Mexican Americans). Because the primary use of
these risk estimates is to facilitate the very important
discussion regarding risk reduction through lifestyle change,
the imprecision introduced is small enough to justify proceeding
with lifestyle change counseling informed by these results.

Data message
Once acceptable response is achieved with lipid-lowering therapy, continue to monitor adherence to lifestyle modifications, medications, and LDL-C response to therapy. If persistent hypertriglyceridemia , refer to the ACC Hypertriglyceridemia application.
Considerations for Lowering LDL-C
It is recommended that for adults aged 20-39 years with long duration of diabetes, albuminuria, eGFR <60 ml/min/1.73 m2, retinopathy, neuropathy, or ABI <0.9, it may be reasonable to initiate statin therapy.
Once acceptable response is achieved with lipid-lowering therapy, continue to monitor adherence to lifestyle modifications, medications, and LDL-C response to therapy. If persistent hypertriglyceridemia , refer to the ACC Hypertriglyceridemia application.
Once acceptable response is achieved with lipid-lowering therapy, continue to monitor adherence to lifestyle modifications, medications, and LDL-C response to therapy. If persistent hypertriglyceridemia , refer to the ACC Hypertriglyceridemia application.
Considerations for Lowering LDL-C
It is reasonable to continue moderate- or high-intensity statin therapy in patients with diabetes after age 75 years if therapy is well-tolerated.
It may be reasonable to have a clinician patient discussion in which the potential benefits and risks of initiating statin therapy in this age group are reviewed. The decision to initiate nonstatin therapy in individuals >75 years of age should be individualized based on considerations of expected longevity, frailty, polypharmacy, susceptibility to adverse effects of treatment, and goals of care.
Once acceptable response is achieved with lipid-lowering therapy, continue to monitor adherence to lifestyle modifications, medications, and LDL-C response to therapy. If persistent hypertriglyceridemia , refer to the ACC Hypertriglyceridemia application.
Considerations for Lowering LDL-C
Patients aged <40 years without ASCVD but with ASCVD risk factors should not be considered for 10-year risk assessment
Adults <40 years of age with LDL-C values ≥160 mg/dL and/or a family history of premature cardiovascular disease may benefit from statin consideration.
In patients with a family history of premature ASCVD, measurement of lipoprotein a (Lp(a)) may help identify patients who may benefit from early statin initiation due to the high heritability of Lp(a) and its well-known association with higher ASCVD risk. For patients >32 years of age, CAC scoring has been shown to help identify those patients with traditional risk factor burden or a family history of premature cardiovascular disease. These patients may be at higher long-term absolute risks for cardiovascular disease and therefore may be more likely to experience potential benefit from statin initiation in early adult life.
Continue to monitor adherence to lifestyle modifications, medications, and LDL-C response to therapy. If persistent hypertriglyceridemia , refer to the ACC Hypertriglyceridemia application.
If lipid-lowering response is still less-than-anticipated
, it may be reasonable to consider PCSK9 mAb. Please refer to the 2018 Guideline information on PCSK9 mAb.
Once acceptable response is achieved with lipid-lowering therapy, continue to monitor adherence to lifestyle modifications, medications, and LDL-C response to therapy. If persistent hypertriglyceridemia , refer to the ACC Hypertriglyceridemia application.

Considerations for Lowering LDL-C
In primary prevention patients >75 years of age, the patient clinician discussion should consider the limited adequate RCT data to inform these decisions. The writing committee recommends consideration of ASCVD risk in the context of patient goals, competing risks for non-cardiovascular disease death, patient frailty, susceptibility to adverse effects, and polypharmacy to derive individual-level recommendations for statin initiation in this highly heterogenous groups.
When the goals of therapy in the clinician patient discussion have been achieved, it is reasonable to continue to monitor adherence to lifestyle modifications, medication, and LDL-C response to therapy. If there is persistent hypertriglyceridemia , clinicians should refer to the ACC Hypertriglyceridemia application.

Optimizing Lifestyle and Medication Therapy
Addressing adherence
Assess the number of missed statin doses per month.
Evaluate barriers to adherence. See patient tools in the Reference Section of this app for help.
Addressing lifestyle
Diet
Consume a dietary pattern that emphasizes intake of vegetables, fruits, and whole grains; includes low-fat dairy products, poultry, fish, legumes, non-tropical vegetable oils, and nuts; and limits intake of sweets, sugar-sweetened beverages, and red meats.
Adapt this dietary pattern to appropriate calorie requirements, personal and cultural food preferences, and nutrition therapy for other medical conditions (including diabetes).

Patient-Clinician Discussion Points for Adding Non-Statin Therapy
Potential for additional ASCVD risk reduction from addition of nonstatin therapy to evidence-based statin therapy to lower LDL-C
Percentage LDL-C reduction achieved with evidence-based statin therapy (if <50% and not on maximally tolerated statin, should increase statin therapy first and reinforce lifestyle modifications) and whether patient is above LDL-C threshold for consideration of nonstatin therapies
Available scientific evidence of ASCVD risk reduction (and magnitude of benefit) when nonstatin therapy is added to evidence-based statin therapy
Additional desired % LDL-C lowering beyond that achieved on evidence-based statin therapy
Mean percentage LDL-C lowering expected with proposed nonstatin therapy when added to evidence-based statin therapy
Potential for clinically significant adverse events or drug-drug interactions from addition of nonstatin therapy to evidence-based statin therapy for lowering LDL-C
Potential out-of-pocket cost of therapy to the patient (e.g., insurance plan coverage, pharmacy or medical benefit, copayment, availability of assistance programs)
Patient’s perception of benefit from addition of nonstatin therapy
Convenience of nonstatin therapy (e.g., route, setting [home or medical office], frequency of administration, pill burden, storage)
Potential of nonstatin therapy to jeopardize adherence to other evidence-based therapies
Anticipated life expectancy, comorbidities, and impact of therapy on quality of life
Once acceptable response is achieved with lipid-lowering therapy, continue to monitor LDL-C level and
adherence to medications and lifestyle. If persistent hypertriglyceridemia see ACC’s Hypertriglyceridemia App
for help.
Potential for non-statin therapy to help lower LDL-C and reduce ASCVD risk
Discuss w/ patients w/o ASCVD, or with LDL-C ≥ 190:
"Your Baseline 10-year ASCVD Risk before starting statin treatment was …"
Clinician Note: 10-year risk > 20% and/or baseline LDL > 160 mg/dL are considered high risk markers for ASCVD.
(If unsure of patient’s baseline risk, use ASCVD Risk Estimator tool in this app to calculate)
Discuss w/ patients w/ ASCVD:
"Evidence shows that being on an appropriate statin has an effect on your risk of recurrent events."
Example: In the Treating New Targets trial, patients with CHD who received Atorvastatin 10 mg daily had a 5-year event rate of 10.9%, and those who received 80 mg of atorvastatin daily had a 5-year event rate of 8.7%.
Discuss with all patients:
"You also have the following high risk markers for ASCVD and comorbidities that could contribute to your risk..."
Clinician Note: Indicate which of the following risk markers and comorbidities the patient has.
10-year ASCVD risk > 20%
LDL-C > 160 mg/dL at baseline
family history of premature ASCVD with or without elevated Lp(a), or ASCVD event ( recent (<3 months) or while taking a statin
other poorly controlled major ASCVD risk factor(s) (e.g. smoking, hypertension)
elevated lipoprotein(a)
elevated hs-CRP
evidence of accelerated subclinical atherosclerosis (e.g., coronary artery calcification)
diabetes
symptomatic heart failure
CKD with or without maintenance hemodialysis
other risk-modifying conditions (e.g. HIV, chronic inflammatory disorders)
"You may help lower your ASCVD risk by addressing these risk factors."
"Evidence shows that a potentially effective way to reduce your ASCVD risk is by lowering your LDL-C."
Example: For each 40 mg/dL reduction in LDL-C using evidence based therapies, there appears to be an approximate 20% relative reduction in ASCVD risk.
"So far on your statin, we’ve been able to reduce your LDL-C by ~%
I would like to reduce it even further."
Clinician Note: If reduction is < 50% and patient not on maximally tolerated statin, should increase statin first and reinforce lifestyle modifications.
Discuss with patient if on maximally tolerated statin, and response had been inadequate:
"Adding non-statin therapy to statins had been shown to potentially help lower LDL-C and reduce ASCVD risk."
Medication-specific examples:
Ezetimibe: May lower LDL-C an additional 25% on average. IMPROVE-IT study showed 6% relative/2% absolute risk reduction in a composite ASCVD endpoint over 7 years when added to a moderate intensity statin.
PCSK9 Inhibitors: May lower LDL-C an additional 60% on average.
Bile Acid sequesterants: Data on ASCVD risk reduction are lacking for addition of BAS to statins.
Niacin preparations: Associated with no benefit and potential for significant harms when added to statin therapy.
"I would like to try one of these additional therapies to help bring your LDL-C down the recommended amount and reduce your ASCVD risk."
Potential adverse events and drug-drug interactions from non-statin therapy
1) Colesevelam: Tablets: 6 tablets PO once daily or 3 tablets PO twice daily; take tablets with a meal and liquid. Suspension: one 3.75-gram packet PO daily, or one 1.875-gram packet PO twice daily; mixed powder with 4–8 ounces of water, fruit juice, or soft drink; take with meal. 3.75 g is equivalent to 6 tablets. 1.875 g is equivalent to 3 tablets
2) Cholestyramine: 8–16 g/day orally divided into 2 doses
3) Colestipol: 2 to 16 g/day orally given once or in divided doses
Mean % LDL reduction
Colesevelam: Monotherapy-15% (6 tablets daily); combination with low- to moderate intensity statin-additional 10-16% reduction in LDL-C (data from simvastatin 10 mg, atorvastatin 10 mg).
Cholestyramine: Monotherapy-10.4% vs placebo. Colestipol: not provided in PI. In dose-ranging RCT with monotherapy, doses of 5 g, 10 g, and 15 g resulted in 16.3%, 22.8%, and 27.2% reduction in LDL-C, respectively. (Superko HR, Greenland P, Manchester RA, et al. Am J Cardiol. 1992;70:135-40.)
Adverse effects
Constipation, dyspepsia, and nausea. Post-marketing reports with colesevelam include ↑ seizure activity or ↓ phenytoin levels in patients receiving phenytoin, ↓ INR in patients receiving warfarin, ↑ TSH in patients receiving thyroid hormone replacement therapy, bowel obstruction, dysphagia, esophageal obstruction, fecal impaction, hypertriglyceridemia, pancreatitis, and increased transaminases.
Drug-drug interactions
cyclosporine, glimepiride, glipizide, levothyroxine, olmesartan coadministered with medoxomil, oral contraceptives containing ethinyl estradiol and norethindrone, phenytoin, warfarin. Drugs with potential interaction should be taken at least 4 hours after BAS to avoid impeding their absorption.
Prescribing considerations
Pill burden; inconvenience in preparation of oral suspension preparations; GI side effects; exacerbation of hypertriglyceridemia; orally administered, colesevelam lowers HbA1c 0.5% in diabetes; CV outcomes data not available.
Food source must be low in saturated fat and cholesterol, and include one or more of the following whole oat or barley foods: 1) oat bran. 2) rolled oats. 3) whole oat flour. 4) whole grain barley or dry milled barley.
Mean % LDL reduction
With intake of 3.0-12.4 g/day, mean TC and LDL-C levels were ↓ relative to control by 9.7 and 11.6 mg/dL, respectively.
Adverse effects
Few safety concerns. If viscous fiber supplements such as fiber laxatives are used, it is critical to consume adequate fluid as directed on the product label to avoid intestinal blockage (a rare occurrence).
Drug-drug interactions
Reduced carotenoid absorption. Regular consumption of fruits and vegetables should help to counteract this potential effect.
Prescribing considerations
GI tolerability
Less than anticipated
If lipid-lowering response is still less than anticipated
Ezetimibe
Variables suggesting ezetimibe initiation:
- Goal is to lower LDL-C by up to an additional 25%
- Recent ACS <3 months
- Cost considerations with recent availability of generic ezetimibe and future cost savings
- Ease of use as oral agent with low pill burden
- Consistent with patient preferences
Variables indicating greatest likelihood of benefit from adding ezetimibe following ACS are:
- Congestive heart failure
- Hypertension
- Age >75 years
- Diabetes
- Stroke
- CABG
- PAD
- eGFR <60 mL/min per 1.73m2
- Smoking
May consider a bile acid sequesterant (BAS) as optional alternative agent if ezetimibe intolerant and triglycerides <300 mg/dL (EC). Patients who achieve <50% LDL-C reduction and triglycerides <300 mg/dL while taking maximally tolerated statin and ezetimibe, addition of BAS may be considered (IIB, B).
PCSK9 Inhibitors
Recommendations from recent 2018 ACC/AHA Cholesterol Guideline:
- In patients 30 to 75 years of age with heterozygous FH and with an LDL-C level of 100 mg/dL (≥2.6 mmol/L) or higher while taking maximally tolerated statin and ezetimibe therapy, the addition of a PCSK9 inhibitor may be considered. (IIb, B)
- In patients 40 to 75 years of age with a baseline LDL-C level of 220 mg/dL (≥5.7 mmol/L) or higher and who achieve an on-treatment LDL-C level of 130 mg/dL (≥3.4 mmol/L) or higher while receiving maximally tolerated statin and ezetimibe therapy, the addition of a PCSK9 inhibitor may be considered. (IIb, C)
- In patients with clinical ASCVD, who are judged to be very high-risk and considered for PCSK9 therapy, maximally tolerated LDL-C lowering therapy should include maximally tolerated statin therapy and ezetimibe. (I,B)
- In patients with clinical ASCVD, who are judged to be very high-risk and who are on maximally tolerated LDL-C lowering therapy with LDL-C ≥70 mg/dL or non-HDL-C ≥100 mg/dL, it is reasonable to add a PCSK9 inhibitor following a clinician-patient discussion about the net benefit, safety, and cost. (IIa, A)
- Patients with clinical ASCVD who are judged to be very high risk include those with a history of multiple major ASCVD events or one major ASCVD event and multiple high-risk conditions
Additional suggestions:
- Please see section 7 of the 2018 ACC/AHA Cholesterol Guideline for a full discussion of cost and value considerations for PCSK9 inhibitors.
- May be preferred in addition to ezetimibe if patient requires >25% additional LDL-C lowering.
- Strongly consider if fully statin intolerant and attempts to lower LDL-C with ezetimibe or BAS result in persistent <50% LDL-C reduction (or may consider LDL-C ≥ 70 mg/dL or non-HDL-C ≥ 100 mg/dL).
- It is reasonable to engage in a clinician-patient discussion with consideration of
Net risk reduction benefit of a PCSK9 inhibitor
Cost
Administration by subcutaneous injection
Every 14-day or monthly dosing schedule
Storage requirements (refrigeration)
Clinicians should preferentially prescribe drugs that have been shown in RCT's to provide ASCVD risk-reduction benefits that outweigh the potential for adverse effects and drug-drug interactions, and consider patient preferences.
If lipid-lowering response is still less than anticipated after non-statin agent(s)
Referral to a lipid specialist and registered dietician nutritionist recommended.
Hypertriglyceridemia
Having fasting triglycerides ≥ 150 mg/dL
FH Diagnostic Categories
ICD-10 Category
Clinical Criteria
With Genetic Testing Performed
Heterozygous FH
LDL-C ≥160 mg/dL (4 mmol/L) for children and ≥190 mg/dL (5 mmol/L) for adults and with 1 first-degree relative similarly affected or with premature CAD or with positive genetic testing for a LDL-C–raising gene defect (LDL receptor, apoB, or PCSK9)
Presence of 1 abnormal LDL-C–raising gene defect (LDL receptor, apoB, or PCSK9). Diagnosed as heterozygous FH if LDL-C–raising defect positive and LDL-C <160 mg/dL (4 mmol/L). Occasionally, heterozygotes will have LDL-C >400 mg/dL (10 mmol/L); they should be treated similarly to homozygotes. Presence of both abnormal LDL-C–raising gene defects (LDL receptor, apoB, or PCSK9) and LDL-C–lowering gene variant(s) with LDL-C <160 mg/dL (4 mmol/L).
Homozygous FH
LDL-C ≥400 mg/dL (10 mmol/L) and 1 or both parents having clinically diagnosed FH, positive genetic testing for a LDL-C–raising gene defect (LDL receptor, apoB, or PCSK9) or autosomal-recessive FH. If LDL-C >560 mg/dL (14 mmol/L) or LDL-C >400 mg/dL (10 mmol/L) with aortic valve disease or xanthomata at <20 y of age, homozygous FH highly likely.
Presence of 2 identical (true homozygous FH) or nonidentical (compound heterozygous FH) abnormal LDL–raising gene defects (LDL receptor, apoB, or PCSK9); includes the rare autosomal-recessive type. Occasionally, homozygotes will have LDL-C <400 mg/dL (10 mmol/L).
Family history of FH
LDL-C level not a criterion; presence of a first-degree relative with confirmed FH
Genetic testing not performed
Abbrevations:
apoB = apolipoprotein B
CAD = coronary artery disease
FH = familial hypercholesterolemia

Phytosterols
Doses and administration
1-3 g PO per day consumed with meals either once daily or in divided doses
Mean % LDL reduction
Consumption of 2 g/day of phytosterols ↓ LDL-C by 5-15%. LDL-C ↓ plateaus at doses above ~3 g/day.
Adverse effects
Phytosterol esters have "generally recognized as safe" (GRAS) status in the US. Potential safety concern regarding phytosterol consumption in patients with phytosterolemia. Side effects may include mild bloating, diarrhea, or constipation.
Drug-drug interactions
BAS administration should be separated from phytosterol use by 2-4 hours to avoid binding of the latter in the gut.
Prescribing considerations
Generally well tolerated; modest ↓ in LDL-C; CV outcomes data not available.
PCSK9 inhibitors
Doses and administration
Alirocumab—initiate 75 mg subcutaneously (SQ) every 2 weeks. If more LDL reduction needed, may ↑ dose to 150 mg every 2 weeks. Alternative starting dose is 300 mg SQ every 4 weeks.
Evolocumab—in primary hypercholesterolemia with established clinical ASCVD or HeFH, give 140 mg SQ every 2 weeks or 420 mg SQ once monthly in abdomen, thigh, or upper arm. In HoFH, give 420 mg SQ once monthly. To administer 420 mg, give 3 (140 mg) injections consecutively within 30 minutes.
Mean % LDL reduction
Alirocumab—when added to maximally tolerated statin therapy, alirocumab 75 mg and 150 SQ every 2 weeks ↓ LDL-C by an additional 43% and 47%, respectively. When added to maximally tolerated statin therapy evolocumab 140 mg every 2 weeks and 420 mg SQ every 4 weeks, ↓ LDL-C by an additional 64% and 58%, respectively.
Adverse effects
Alirocumab—nasopharyngitis, injection site reactions, influenza.
Evolocumab—nasopharyngitis, upper respiratory tract infection, influenza, back pain, and injection site reactions. No evidence of increase in cognitive adverse effects observed in FOURIER or EBBINGHAUS.
Drug-drug interactions
No clinically significant drug-drug interactions identified for alirocumab or evolocumab.
Prescribing considerations
Cost, SQ administration, robust LDL-C reduction, CV outcomes trials not completed for alirocumab, burdensome prior authorization process.
Inhibits NPC1L1 protein; reduces cholesterol absorption in small intestine.
FDA-approved indication(s):

Dose and route of administration:
Initiate 5 mg orally once daily. Titrate dose based on acceptable safety/tolerability: increase to 10 mg daily after at least 2 weeks and then, at a minimum of 4-week intervals, to 20 mg, 40 mg, up to the maximum recommended dose of 60 mg daily.
Mean % LDL reduction (per PI):
Mean and median percent changes in LDL-C from baseline when added to baseline lipid-lowering therapy were -40% and -50%, respectively.
Black box warnings:
1) May cause elevations in liver transaminases; measure ALT, AST, alkaline phosphatase, total bilirubin before initiating this medication; during treatment, adjust dose if ALT or AST ≥3 times the upper limit of normal; discontinue this medication for clinically significant liver toxicity.
2) Increases hepatic fat (hepatic steatosis) with or without concomitant increases in transaminases. Hepatic steatosis associated with lomitapide may be a risk factor for progressive liver disease, including steatohepatitis and cirrhosis. Because of the risk of hepatotoxicity, lomitapide is only available through the REMS program.
Contraindication:
1) Pregnancy
2) Concomitant use with strong/moderate CYP3A4 inhibitors.
3) moderate/severe hepatic impairment or active liver disease including unexplained persistent abnormal liver function tests.
Warnings/precautions:
1) May cause fetal toxicity; inform patients who may become pregnant of risk to fetus; obtain a pregnancy test before initiating therapy in patients who may become pregnant; advise patients who may become pregnant to use contraception during treatment and for ≥2 weeks following the last dose. Discontinue this medication if patient becomes pregnant. Clinicians should report pregnancies that occur while taking this medication (1-877-902-4099).
Adverse effects:
Diarrhea, nausea, vomiting, dyspepsia, and abdominal pain.
Use during pregnancy/lactation:
Avoid use.
Drug–drug interactions:
1. CYP3A4 inhibitors increase exposure to lomitapide. Strong/moderate CYP3A4 inhibitors are contraindicated with lomitapide. Avoid grapefruit juice.
2. Do not exceed 30 mg daily of lomitapide when used concomitantly with weak CYP3A4 inhibitors, including atorvastatin and oral contraceptives.
3. Increases plasma concentration of warfarin; monitor INR regularly, especially with lomitapide dose adjustment.
4. Increased systemic exposure to simvastatin and lovastatin exposure with lomitapide. Limit statin dose when coadministered due to myopathy risk.
5. Consider dose reduction of P-glycoprotein substrates because of possible increased absorption with lomitapide.
6. Separate lomitapide dosing with BAS by at least 4 hours.
CV Outcomes Trials:
The effect of lomitapide on CV morbidity and mortality has not been determined
Considerations in prescribing:
Cost, oral administration, requires strict adherence to low-fat diet and gradual dose escalation to reduce GI side effects, requires daily doses of specific vitamins (Vitamin E 400 IU, linoleic acid ≥200 mg, alpha-linolenic acid ≥210 mg, eicosapentaenoic acid ≥110 mg, docosahexaenoic acid ≥80 mg); requires monitoring of transaminase levels, long-term consequences of hepatic steatosis unknown, prescriber training, REMS program.
LDL Apheresis
Mechanism of action:
Selectively removes apo B-containing lipoproteins, producing an acute reduction in LDL-C.
FDA-approved indication:
Patients with FH unresponsive to pharmacologic and dietary management who are either functional homozygotes with an LDL-C >500mg/dL, functional heterozygotes with no known CV disease but an LDL-C >300mg/dL, or functional heterozygotes with known cardiovascular disease and LDL-C >200mg/dL
Dose and route of administration:
Extracorporeal technique performed weekly or biweekly
Mean % LDL-C reduction :
With weekly or biweekly treatment, average LDL-C can ↓ to ~50–60% of the original levels. LDL-C increases after each apheresis session but does not return to the original level
Adverse effects:
Problems with venous access; transient hypotension, fatigue; bleeding; hypocalcemia; iron deficiency due to regular phlebotomy for diagnostic purposes; heparin allergy; and bradykinin syndrome (especially with ACEi)
Drug–drug interactions:
ACEi should not be used with dextran sulfate method owing to risk of bradykinin syndrome.
CV Outcomes Trials:
Limited due to ethical considerations in RCTs of very high-risk patients with HoFH, but it is reasonable to assume reductions in CV disease events are proportional to the degree of LDL-C lowering.
Considerations in prescribing:
Cost, extracorporeal technique, inconvenient, locations not readily available in some regions, time-consuming, robust reduction in LDL-C.
Moderate Intensity Statin
Evaluate for statin intolerance
Evaluate for statin intolerance if unable to tolerate a moderate intensity statin . See ACC's Statin Intolerance App for help.
Nonabsorbed, lipid-lowering polymer that binds bile acids in the intestine and impedes their reabsorption. As the bile acid pool ↓, the hepatic enzyme, cholesterol 7-α-hydroxylase, is upregulated, which ↑ conversion of cholesterol to bile acids. This causes ↑ demand for cholesterol in the liver cells, resulting in the dual effect of increasing transcription and activity of the cholesterol biosynthetic enzyme HMG-CoA reductase and ↑ the number of hepatic LDL receptors. These compensatory effects result in ↑ clearance of LDL particles from the blood, in turn resulting in ↓ serum LDL-C levels. Serum TG levels may ↑ or remain unchanged.
FDA-approved indication(s):
Colesevelam: As an adjunct to diet and exercise to
1) ↓ LDL-C in adults with primary hyperlipidemia;
2) ↑ glycemic control in adults with type 2 diabetes;
3) ↓ LDL-C in boys and post-menarchal girls (10 to 17 years of age) with HeFH who are unable to reach LDL-C targets after an adequate trial of diet therapy and lifestyle modifications
Cholestyramine, colestipol: ↓ LDL-C with primary hyperlipidemia, as adjunct to diet
Dose and route of administration:
Colesevelam: Tablets: 6 tablets orally once daily or 3 tablets orally twice daily; take tablets with a meal and liquid. Suspension: one 3.75-g packet orally daily, or one 1.875-g packet orally twice daily; mix powder with 8 ounces of water, fruit juice, or soft drink; take with meal. 3.75 g is equivalent to 6 tablets. 1.875 g is equivalent to 3 tablets;
Cholestyramine: 8–16 g/day orally divided into 2 doses.
Colestipol: Complete biliary obstruction, history of serious hypersensitivity to this medication.
Mean % LDL reduction (per PI):
Colesevelam: Monotherapy—15% (6 tablets daily); in combination with low- to moderate-intensity statin therapy—additional 10%-16% reduction in LDL-C (data from simvastatin 10 mg, atorvastatin 10 mg). Cholestyramine: Monotherapy—10.4% vs placebo.
Colestipol: not provided in PI. In dose-ranging RCT with monotherapy, doses of 5, 10, and 15 g resulted in 16.3%, 22.8%, and 27.2% reductions in LDL-C, respectively
Contraindications (per PI):
Colesevelam: TG >500 mg/dL; history of hypertriglyceridemia-induced pancreatitis; bowel obstruction.
Cholestyramine: History of serious hypersensitivity to this medication.
Colestipol: Complete biliary obstruction, history of serious hypersensitivity to this medication.
Warnings/precautions:
May ↑ TG and cause acute pancreatitis, monitor TG, discontinue if signs and symptoms of acute pancreatitis occur; may cause GI obstruction, avoid with gastroparesis, other GI motility disorders, and history of major GI tract surgery with risk for bowel obstruction; may cause vitamin K or fat-soluble vitamin deficiencies, oral vitamins should be given ≥4 hours before this medication; may decrease absorption of other medications, other medications should be given ≥4 hours before this medication. Some products contain phenylalanine, which may be harmful to patients with phenylketonuria.
Adverse effects:
Constipation, dyspepsia, and nausea.
Use during pregnancy/lactation:
Considered safe to use
Drug–drug interactions:
In general, BAS may decrease absorption of other medications; it is a good practice for all other medications to be given ≥4 hours before BAS. Concomitant use of BAS is known to decrease absorption of cyclosporin, oral contraceptives containing ethinyl estradiol and norethindrone, olmesartan, phenytoin, sulfonylureas, thyroid replacement therapy, warfarin; give these medications ≥4 hours before BAS. For patients on warfarin, monitor INR frequently during BAS initiation and then periodically. Cholestyramine may increase exposure to metformin; monitor glycemic control.
CV Outcomes Trials:
In LRC-CPPT, 3,806 asymptomatic middle-aged men with primary hypercholesterolemia were randomized to cholestyramine resin vs placebo for an average of 7.4 years. The cholestyramine group experienced a 19% reduction in risk (P < 0.05) of the primary endpoint—definite CHD death and/or definite nonfatal MI. The effects of colesevelam and colestipol on cardiovascular morbidity and mortality have not been determined.
Considerations in prescribing:
Pill burden; inconvenience in preparation of oral suspension preparations; drug interactions, GI side effects; exacerbation of hypertriglyceridemia; orally administered, colesevelam lowers HbA1c 0.5% in diabetes; CV outcomes data not available for all products.

High-risk Conditions
Age ≥ 65 y
Heterozygous familial hypercholesterolemia
History of prior coronary artery bypass surgery or percutaneous coronary intervention outside of the major ASCVD event(s)

PAD = peripheral artery disease
Risk-Enhancing Factors for Clinician–Patient Risk Discussion
Family history of premature ASCVD (males, age < 55 y; females age <65 y)
Metabolic syndrome (increased waist circumference, elevated triglycerides [≥150 mg/dL], elevated blood pressure, elevated glucose, and low HDL-C [ <40 mg/dL in men; <50 mg/dL in women] are factors; tally of 3 makes the diagnosis
Chronic kidney disease (eGFR 15–59 mL/min/1.73 m² with or without albuminuria; not treated with dialysis or kidney transplantation)
Chronic inflammatory conditions such as psoriasis, RA, or HIV/AIDS
History of premature menopause (before age 40 y) and history of pregnancy-associated conditions that increase later ASCVD risk such as preeclampsia
High-risk race/ethnicities (e.g., South Asian ancestry)
Lipid/biomarkers: Associated with increased ASCVD risk
Elevated high-sensitivity C-reactive protein (≥2.0 mg/L)
Elevated Lp(a): A relative indication for its measurement is family history of premature ASCVD. An Lp(a) ≥50 mg/dL or ≥125 nmol/L constitutes a risk-enhancing factor especially at higher levels of Lp(a).
Administration by subcutaneous injection
Elevated apoB ≥130 mg/dL: A relative indication for its measurement would be triglyceride ≥200 mg/dL. A level ≥130 mg/dL corresponds to an LDL-C≥160 mg/dL and constitutes a risk-enhancing factor
ABI <0.9
Lipid Specialist
Approach
Consider referring patients with baseline LDL-C ≥190 mg/dL, very high risk for ASCVD, complex lipid disorders, statin intolerance or multiple lipid medication intolerances, or familial hypercholesterolemia for consultation with a lipid specialist for advanced management.
Considerations
Lipid specialists may not be easily available in some rural or remote locations.
Lomitapide
Doses and administration
Initiate 5 mg PO once daily. Titrate dose based on acceptable safety/tolerability: increase to 10 mg daily after at least 2 weeks and then, at a minimum of 4-week intervals, to 20 mg, 40 mg, and up to maximum recommended dose of 60 mg daily.
Mean % LDL reduction
Mean and median percent changes in LDL-C from baseline when added to baseline lipid-lowering therapy were -40% and -50%, respectively.
Adverse effects
Diarrhea, nausea, vomiting, dyspepsia, and abdominal pain. Increases hepatic fat (hepatic steatosis) with or without concomitant increases in transaminases. Hepatic steatosis associated with lomitapide may be a risk factor for progressive liver disease, including steatohepatitis and cirrhosis.
Drug-drug interactions
CYP3A4 inhibitors increase exposure to lomitapide. Strong and moderate CYP3A4 inhibitors are contraindicated with lomitapide. Avoid grapefruit juice. Do not exceed 30 mg daily of lomitapide when used concomitantly with weak CYP3A4 inhibitors, including atorvastatin and oral contraceptives. Increases plasma concentrations of warfarin; monitor INR regularly, especially with lomitapide dose adjustment. Increased systemic exposure to simvastatin and lovastatin exposure with lomitapide. Limit statin dose when co-administered due to myopathy risk. Consider dose reduction of P-gp substrate because of possible increased absorption with lomitapide. Separate lomitapide dosing with BAS by at least 4 hours. Because of the risk of hepatotoxicity, lomitapide available only through REMS program.
Prescribing considerations
Cost, oral administration, requires strict adherence to low-fat diet and gradual dose escalation to reduce GI side effects, requires monitoring of transaminase levels, long-term consequences of hepatic steatosis unknown, prescriber training, REMS program
Response to addition of mipomersen to maximally tolerated lipid-lowering medication in patients with HoFH—25%.
Adverse effects
Injection site reactions, flu-like symptoms, nausea, headache and elevations in serum transaminases, specifically ALT. Increases hepatic fat (hepatic steatosis) with or without concomitant increases in transaminases. May be a risk factor for progressive liver disease, including steatohepatitis and cirrhosis. Because of the risk of hepatotoxicity, mipomersen is available only through REMS program
Drug-drug interactions
No clinically relevant pharmacokinetic interactions were reported between mipomersen and warfarin, simvastatin, or ezetimibe.
Prescribing considerations
Cost, SQ administration, requires monitoring of transaminase levels, long-term consequences of hepatic steatosis unknown, prescriber training, REMS program
Extracorporeal technique performed weekly or biweekly.
Mean % LDL reduction
With weekly or biweekly treatment, average LDL-C can ↓ to ~50–60% of the original levels. LDL-C increases after each apheresis session but does not return to the original level
Adverse effects
Problems with venous access; transient hypotension, fatigue; bleeding; hypocalcemia; iron deficiency due to regular phlebotomy for diagnostic purposes; heparin allergy; and bradykinin syndrome (especially with ACEI).
Drug-drug interactions
ACEI should not be used with dextran sulfate method owing to risk of bradykinin syndrome.
Prescribing considerations
Cost, extracorporeal technique, inconvenient, locations not readily available in some regions, time-consuming, robust reduction in LDL-C.
Homozygous FH*
Clinical Criteria
LDL-C ≥400 mg/dL (10 mmol/L) and 1 or both parents having clinically diagnosed FH, positive genetic testing for a LDL-C raising gene defect (LDL receptor, apoB, or PCSK9) or autosomal-recessive FH
If LDL-C >560 mg/dL (14 mmol/L) or LDL-C >400 mg/dL (10 mmol/L) with aortic valve disease or xanthomata at <20 years of age, homozygous FH highly likely
With Genetic Testing Performed
Presence of 2 identical (true homozygous FH) or nonidentical (compound heterozygous FH) abnormal LDL raising gene defects (LDL receptor, apoB, or PCSK9); includes the rare autosomal-recessive type
Occasionally, homozygotes will have LDL-C <400 mg/dL (10 mmol/L)

The option to calculate risk will appear in this part of the app for patients 40 – 75 years old. This age range is determined by the studies upon which the 10-year risk score is based, as well as the Hypertriglyceridemia expert consensus content.
Diabetes-specific high-risk features include long duration (≥10 years for type 2 diabetes or ≥20 years for type 1 diabetes, albuminuria ≥30 mcg of albumin/mg creatinine, eGFR <60 mL/min/1.73 m², retinopathy, neuropathy, ankle-brachial index <0.9.
Significant atherosclerotic plaque observed in an asymptomatic patient on any of the following diagnostic studies: coronary artery calcification noted on computed tomography (CT) studies, including calcium scoring, cardiac CT coronary angiography, chest CT for ruling out pulmonary embolism, chest CT for lung cancer screening, or diagnostic chest CT; carotid plaque noted on carotid ultrasound or angiography; or abnormal ankle-brachial index or plaque noted on peripheral arterial angiography.
These are factors that may be considered within the context of individual patients, not firm triggers for adding medication.
Use clinical judgement. In general, patients should be treated first with maximally-tolerated statin intensity (in addition to lifestyle) before considering additional medications. Patients unable to tolerate even a moderate-intensity statin should be evaluated for statin intolerance.
