Illustration of Coronary Artery Stenosis

Coronary artery stenosis is a medical condition characterized by the narrowing of the coronary arteries, which supply blood to the heart. This condition is primarily caused by atherosclerosis, a disease in which plaque builds up inside the arteries.

Causes

The primary cause of coronary artery stenosis is atherosclerosis. Other causes include coronary artery spasm, coronary artery dissection, and coronary artery aneurysm.

Symptoms

Symptoms of coronary artery stenosis can vary, but often include chest pain, shortness of breath, and fatigue. In severe cases, it can lead to heart attack or cardiac arrest.

Diagnosis

Diagnosis of coronary artery stenosis typically involves a physical examination, medical history, and various tests such as electrocardiogram, echocardiogram, and coronary angiography.

Treatment

Treatment for coronary artery stenosis can include lifestyle changes, medication, and in severe cases, coronary artery bypass surgery or percutaneous coronary intervention.
