Management of Hypertriglyceridemia

Initial Assessment and Risk Stratification

The American College of Cardiology recommends screening for uncontrolled diabetes mellitus, as poor glycemic control is often the primary driver of severe hypertriglyceridemia and optimizing glucose control can dramatically reduce triglycerides independent of lipid medications 2, 3
The American College of Cardiology suggests evaluating renal function, as chronic kidney disease elevates triglycerides and impacts medication dosing 2
The American College of Cardiology advises reviewing medications that raise triglycerides, such as thiazide diuretics, beta-blockers, estrogen therapy, corticosteroids, antiretrovirals, and antipsychotics, and discontinuing or substituting them if possible 3
The American College of Cardiology recommends quantifying alcohol intake, as even 1 ounce per day corresponds to 5-10% higher triglyceride levels 3
The American College of Cardiology suggests calculating 10-year ASCVD risk to determine statin intensity, as a triglyceride level of 305 mg/dL is classified as moderate hypertriglyceridemia and represents a cardiovascular risk-enhancing factor 1, 2, 3

The American College of Cardiology recommends targeting 5-10% body weight reduction, which produces a 20% decrease in triglycerides and is the single most effective lifestyle intervention 2, 3
The American College of Cardiology advises engaging in at least 150 minutes per week of moderate-intensity aerobic activity, which reduces triglycerides by approximately 11% 2, 3
The American College of Cardiology suggests restricting added sugars to <6% of total daily calories, as sugar intake directly increases hepatic triglyceride production 2, 3
The American College of Cardiology recommends limiting total fat to 30-35% of total daily calories 2, 3
The American College of Cardiology advises restricting saturated fats to <7% of total calories and eliminating trans fats completely 1, 3
The American College of Cardiology suggests increasing soluble fiber to >10 g/day and incorporating plant stanols/sterols 4, 3
The American College of Cardiology recommends consuming at least 2 servings (8+ ounces) per week of fatty fish rich in omega-3 fatty acids 4, 3
The American College of Cardiology advises limiting or completely avoiding alcohol consumption, as alcohol significantly raises triglyceride levels and can precipitate hypertriglyceridemic pancreatitis 4, 2, 3

The American College of Cardiology recommends initiating or optimizing moderate-to-high intensity statin therapy if the patient has diabetes, established ASCVD, or 10-year ASCVD risk ≥7.5% 1, 5, 2
The American College of Cardiology suggests targeting non-HDL-C <130 mg/dL as a secondary goal when triglycerides are 200-499 mg/dL 2, 3
The American College of Cardiology recommends adding prescription omega-3 fatty acids (icosapent ethyl 2-4 g/day) if triglycerides remain >200 mg/dL after 3 months of optimized lifestyle modifications and statin therapy 2, 3
The American College of Cardiology advises monitoring for increased risk of atrial fibrillation with prescription omega-3 fatty acids 2, 3

The American Geriatrics Society recommends dose selection for elderly patients based on renal function 7
The American College of Cardiology suggests continuing moderate- or high-intensity statin therapy in patients with diabetes after age 75 if therapy is well-tolerated 5

The American College of Cardiology recommends reassessing fasting lipid panel in 6-12 weeks after implementing lifestyle modifications 3
The American College of Cardiology suggests monitoring lipid levels at 4-8 week intervals after initiating or adjusting pharmacologic therapy 2, 3
The American College of Cardiology advises following up every 6-12 months once goals are achieved 3

The American College of Cardiology recommends not starting with fibrate monotherapy for moderate hypertriglyceridemia, as statins provide proven cardiovascular benefit and fibrates have not shown ASCVD outcome improvement when combined with statins 4, 2
The American College of Cardiology advises not delaying lifestyle interventions while waiting for medications to take effect, as dietary changes can be more effective than additional medications in some cases 2, 3
The American College of Cardiology suggests not overlooking glycemic control in diabetic patients, as this can be more effective than additional lipid medications for severe hypertriglyceridemia 2, 3
The American College of Cardiology recommends not using over-the-counter fish oil supplements as substitutes for prescription omega-3 formulations, as they are not equivalent 3
The American College of Cardiology advises not combining high-dose statins with fibrates without careful consideration of myopathy risk, especially in elderly patients 2, 3
