From the Guidelines

Hyperlipidemia is a medical condition characterized by abnormally high levels of lipids (fats) in the blood, including cholesterol and triglycerides, which increases the risk of cardiovascular diseases such as heart attacks and strokes.

Definition and Causes

Hyperlipidemia can be categorized as primary (genetic) or secondary (resulting from other conditions like diabetes, hypothyroidism, or certain medications) 1. The condition is often associated with elevated levels of low-density lipoprotein (LDL) cholesterol, reduced levels of high-density lipoprotein (HDL) cholesterol, and increased levels of triglycerides.

Diagnosis and Classification

The diagnosis of hyperlipidemia is based on fasting serum lipid levels, with cutoffs defined by various guidelines, including those from the Endocrine Society and the National Cholesterol Education Program (NCEP) 1. The classification of hyperlipidemia is based on the levels of LDL cholesterol, HDL cholesterol, and triglycerides.

Treatment and Management

Treatment of hyperlipidemia typically involves lifestyle modifications, including a heart-healthy diet low in saturated fats and trans fats, regular physical activity, weight management, and smoking cessation 1. When lifestyle changes are not sufficient, medications may be prescribed, with statins (like atorvastatin, rosuvastatin) being first-line therapy for most patients. Other medications include ezetimibe, PCSK9 inhibitors, bile acid sequestrants, and fibrates, depending on the specific lipid abnormalities and patient factors.

Key Recommendations

  • Lifestyle modifications are essential for managing hyperlipidemia, including a heart-healthy diet, regular physical activity, weight management, and smoking cessation.
  • Statins are the first-line therapy for most patients with hyperlipidemia, with other medications used depending on the specific lipid abnormalities and patient factors.
  • Regular monitoring of lipid levels is crucial to assess treatment effectiveness and adjust therapy as needed.
  • Early diagnosis and proper management of hyperlipidemia are critical for preventing serious cardiovascular complications.

From the FDA Drug Label

along with diet to reduce low density lipoprotein cholesterol (LDL-C) or bad cholesterol: in adults with primary hyperlipidemia

Hyperlipidemia is a condition characterized by high levels of cholesterol or fat in the blood.

  • It can be primary, meaning it is an inherited condition, or it can be caused by other factors such as diet or lifestyle.
  • Hyperlipidemia can increase the risk of heart disease, heart attack, and stroke.
  • Atorvastatin calcium tablets are used to treat hyperlipidemia by reducing LDL-C (bad cholesterol) in adults with primary hyperlipidemia 2

From the Research

Definition of Hyperlipidemia

  • Hyperlipidemia refers to elevated levels of blood lipids, which are a well-documented risk factor for cardiovascular disease 3.
  • It is characterized by high levels of low-density lipoprotein (LDL) cholesterol, triglycerides, and total cholesterol in the blood.

Types of Hyperlipidemia

  • Mixed hyperlipidemia is a common disorder marked by elevated very-low-density lipoprotein (VLDL) and LDL levels 4.
  • Hyperlipidemia can be primary (genetic) or secondary (caused by other factors such as diet, lifestyle, or certain medical conditions).

Diagnosis and Treatment

  • The diagnosis of hyperlipidemia is based on blood lipid profiles, which measure the levels of different types of cholesterol and triglycerides in the blood.
  • Treatment of hyperlipidemia typically involves lifestyle modifications, such as diet and exercise, as well as pharmacological interventions, including statins, ezetimibe, and other lipid-lowering medications 5, 6.
  • The choice of treatment depends on the individual's risk factors, lipid profile, and other health conditions.

Management in Special Populations

  • In older individuals, hyperlipidemia management is crucial to prevent cardiovascular disease and its complications 7.
  • Statins are the most commonly used medications for hyperlipidemia in older adults, but other options, such as ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, may be considered in certain cases.
