Hypertriglyceridemia is a growing concern, as it has been linked to an increased risk of both cardiovascular disease and pancreatitis. When triglyceride levels are severely elevated, the risk of pancreatitis rises, necessitating a combination of lifestyle changes and pharmacotherapy to lower these levels.
It is also important to address the underlying causes of hypertriglyceridemia. While the use of statin therapy to target low-density lipoprotein cholesterol (LDL-C) has led to improvements in atherosclerotic cardiovascular disease outcomes, residual risk remains.
In the context of this remaining risk for ASCVD, various studies have demonstrated that even mild to moderate hypertriglyceridemia serves as an independent risk factor for cardiovascular disease. However, the available data does not definitively confirm that treating hypertriglyceridemia reduces the risk of cardiovascular disease.
Epidemiology
Hypertriglyceridemia is relatively common, and its prevalence has been increasing in recent years due to changes in lifestyle and dietary habits. It affects a significant portion of the population, with varying degrees of severity. The prevalence of HTG tends to increase with age. It is more common in adults than in children and adolescents. Men are often more affected than women, but this gender difference can vary depending on the population studied.
It is often associated with other health conditions like cardiovascular disease, diabetes, and obesity. People with these comorbidities are at a higher risk of developing HTG. The prevalence can vary by geographic location and ethnicity. Specific populations may be more susceptible to HTG due to genetic predispositions or dietary practices.
Anatomy
Pathophysiology
Triglycerides are a type of fat found in the blood. They are primarily obtained from dietary fats or synthesized in the liver. Triglycerides are stored in adipose tissue and released into the bloodstream when the body needs energy between meals. Inherited genetic factors can predispose individuals to HTG. Certain gene mutations can affect the metabolism of triglycerides and increase their levels in the blood.
In cases of HTG, the liver may overproduce triglycerides, especially when influenced by dietary factors, obesity, or insulin resistance. The body may have difficulty removing triglycerides from the bloodstream due to the reduced activity of enzymes responsible for breaking down triglycerides. Elevated triglycerides are often associated with changes in lipoproteins, including very low-density lipoproteins (VLDL). VLDL particles carry triglycerides from the liver to peripheral tissues and are closely linked to HTG.
Insulin resistance, often seen in obesity and metabolic syndrome, can lead to HTG. Insulin plays a role in triglyceride metabolism, and its resistance can disrupt this process. High triglyceride levels are an established risk factor for atherosclerosis and cardiovascular disease, as they can lead to the formation of fatty deposits in blood vessels. Severely elevated triglyceride levels increase the risk of acute pancreatitis, which can be fatal.
Etiology
Genetics: In some cases, HTG has a genetic basis. Specific genetic mutations can affect the metabolism of triglycerides, leading to familial or hereditary hypertriglyceridemia. Notable examples include familial hypertriglyceridemia, familial combined hyperlipidemia, and familial dysbetalipoproteinemia.
Dietary Habits: Dietary choices can significantly impact triglyceride levels. Consuming a diet high in carbohydrates, particularly simple sugars, and unhealthy fats, such as saturated and trans fats, can increase triglyceride synthesis in the liver. Overconsumption of calories, especially in the form of high-carbohydrate and high-fat meals, contributes to HTG.
Physical Inactivity: A sedentary lifestyle can reduce the body’s ability to metabolize and remove triglycerides from the blood. Regular physical activity helps improve triglyceride metabolism.
Alcohol Consumption: Excessive alcohol intake can lead to HTG. The liver metabolizes alcohol and converts it into triglycerides, contributing to elevated levels in the bloodstream.
Pregnancy: Pregnancy can cause temporary HTG due to hormonal changes and increased fat storage for fetal development.
Genetics
Prognostic Factors
Clinical History
Healthcare providers should conduct assessments to identify potential secondary causes of hypertriglyceridemia. These causes may encompass factors like alcohol consumption, endocrine disorders, metabolic syndrome, and the use of certain medications.
In cases of primary hypertriglyceridemia, it is essential to evaluate patients for additional cardiovascular risk factors, such as hypertension, obesity, diabetes, and tobacco use. Moreover, it is important to inquire about the family history of lipid disorders, including dyslipidemia and cardiovascular disease.
Physical Examination
In patients with familial dysbetalipoproteinemia, characteristic signs include pathognomonic palmar xanthomas, which are yellow-orange deposits along the creases of the palms, as well as eruptive xanthomas on pressure sites like the elbows, buttocks, and knees.
Chylomicronemia syndrome may manifest with symptoms such as epigastric abdominal pain, eruptive xanthomas on the buttocks and upper limb extensor surfaces, hepatosplenomegaly, acute pancreatitis, temporary memory loss, lipemia retinalis, and, in rare instances, focal neurological deficits.

Treatment Paradigm
The management of hypertriglyceridemia is a multifaceted approach aimed at reducing elevated triglyceride levels and mitigating associated health risks. Lifestyle modifications play a crucial role, emphasizing dietary changes to promote a heart-healthy diet low in saturated fats and sugars, weight management to address obesity and regular physical activity.
Medications, including statins, fibrates, omega-3 fatty acids, niacin, and others, may be prescribed based on the severity of HTG and underlying causes. Treating and managing concurrent conditions like diabetes and metabolic syndrome is also important.
Regular monitoring of triglyceride levels and assessing other cardiovascular risk factors, such as obesity and diabetes, are essential components of effective HTG management. A personalized and comprehensive approach is key to reducing the risk of cardiovascular disease and pancreatitis associated with HTG while improving overall cardiovascular health.

Dietary Changes: A heart-healthy diet low in saturated fats, trans fats, and refined sugars can help lower triglyceride levels. A focus on complex carbohydrates, lean proteins, and healthy fats is essential. Reducing alcohol intake is also important, particularly for those with alcohol-induced HTG.Â
Weight Management: Weight loss, particularly for individuals who are overweight or obese, can significantly reduce triglyceride levels.Â
Physical Activity: Regular physical activity, including aerobic exercise, can help improve triglyceride metabolism. Aim for at least 150 minutes of moderate-intensity exercise per week.Â
Administration with pharmaceutical agent
Statins: Statins, primarily used to lower LDL cholesterol, can also have a moderate effect on lowering triglycerides.Â
Fibrates: Fibrate medications, such as fenofibrate and gemfibrozil, are often used to reduce triglyceride levels. They can also raise high-density lipoprotein cholesterol.Â
Omega-3 Fatty Acids: Prescription-strength omega-3 fatty acid medications, such as icosapent ethyl, can lower triglycerides, especially in patients with very high triglyceride levels.Â
