Treatment Thresholds for Hypertriglyceridemia

Classification and Risk Assessment

Hypertriglyceridemia is classified by severity: normal (<150 mg/dL), mild (150-199 mg/dL), moderate (200-499 mg/dL), severe (500-999 mg/dL), and very severe (≥1000 mg/dL) 1
Fasting triglyceride levels >150 mg/dL or nonfasting triglycerides >175 mg/dL are considered elevated and require attention 2
Moderate hypertriglyceridemia (150-499 mg/dL) is associated with increased cardiovascular disease risk 3
Severe hypertriglyceridemia (≥500 mg/dL) significantly increases the risk of acute pancreatitis 2, 4

For patients with triglycerides 150-499 mg/dL, the American College of Cardiology recommends addressing and treating lifestyle factors, secondary factors, and medications that raise triglycerides 2, 5
Implementing dietary changes, including weight loss and reduced alcohol consumption, is recommended for patients with triglycerides 150-499 mg/dL 2
For patients with ASCVD or other cardiovascular risk factors on a statin with managed LDL cholesterol but elevated triglycerides (150–499 mg/dL), the American College of Cardiology recommends considering adding icosapent ethyl to reduce cardiovascular risk 2

For severe hypertriglyceridemia (≥500 mg/dL), the American College of Cardiology recommends fibrates as first-line therapy to reduce the risk of pancreatitis 3, 4
For moderate hypertriglyceridemia with elevated ASCVD risk (≥7.5%), the American College of Cardiology recommends considering statin therapy 4, 5
Statin plus fibrate combination therapy is generally not recommended due to increased risk of myositis and rhabdomyolysis 2, 7

In patients with diabetes and hypertriglyceridemia, the American Diabetes Association recommends addressing glycemic control first, then re-evaluating triglyceride levels 3, 8
For patients with very severe hypertriglyceridemia (≥1000 mg/dL), extreme dietary fat restriction (<5% of total calories) may be necessary until triglycerides are <1000 mg/dL 9
Patients with fasting triglycerides ≥1000 mg/dL are at highest risk for acute pancreatitis and require aggressive intervention 4, 1
