What are the risks associated with low high-density lipoprotein (HDL) levels?

Generally, low high-density lipoprotein (HDL) cholesterol levels may increase the risk of coronary artery atherosclerotic heart disease, stroke, and cerebral infarction.

1. Coronary Artery Atherosclerotic Heart Disease

Low HDL cholesterol levels may contribute to the development of coronary artery atherosclerotic heart disease. When low HDL is not promptly addressed, it can lead to increased blood viscosity, thereby promoting the progression of coronary artery atherosclerotic heart disease. Common symptoms include chest pain and tightness.

2. Stroke

If coronary heart disease induced by low HDL cholesterol remains untreated, arterial plaques may form. Should these plaques rupture or detach, they can obstruct cerebral blood vessels, triggering a stroke—potentially leading to severe complications, including brain death.

3. Cerebral Infarction

Patients with low HDL cholesterol often experience dyslipidemia. As the condition progresses, it may precipitate cerebral infarction, posing a serious threat to the patient’s life.

Therefore, numerous factors can cause low HDL cholesterol levels. Patients are advised to seek timely medical evaluation to identify the underlying cause and receive appropriate treatment under the guidance of a healthcare professional.
