Coronary Artery Disease (CAD): Causes, Symptoms & Treatment

Coronary occlusive artery disease, also called coronary artery obstruction or simply coronary occlusion, occurs when there is a blockage of one or more of the coronary arteries, the vessels that supply oxygenated blood to the heart muscle. Plaque, an accumulation of cholesterol, fat, calcium, and other substances, slowly builds up on the inner walls of these vessels. As the plaque builds up, it narrows the arteries and restricts the flow of blood.

Depending on the location and severity of the blockage, coronary occlusive artery disease can lead to a variety of medical issues up to and including heart attacks and strokes.

Coronary occlusive artery disease is a serious medical condition that requires treatment to reduce the risk of complications such as heart attack and stroke. Treatment options include lifestyle changes, medications, and surgical interventions.
