Coronary Artery Stenosis

Coronary artery stenosis is a medical condition characterized by the narrowing of one or more of the coronary arteries that supply blood to the heart muscle. This narrowing occurs due to the accumulation of fatty deposits, cholesterol, and other substances, collectively known as plaque, on the inner walls of the arteries. As the plaque builds up, it can restrict blood flow to the heart, leading to a reduction in oxygen and nutrients reaching the cardiac muscles. This diminished blood supply may result in chest pain or angina, and in severe cases, it can lead to a heart attack. Coronary artery stenosis is often associated with atherosclerosis, a chronic inflammatory condition that affects the arteries throughout the body. Lifestyle factors such as a poor diet, lack of physical activity, and smoking, as well as genetic predispositions, contribute to the development of this condition. Management of coronary artery stenosis typically involves lifestyle modifications, medications, and, in some cases, surgical interventions such as angioplasty or coronary artery bypass grafting to restore blood flow to the heart muscle. Early detection and intervention are crucial for preventing complications and preserving heart health.
