coronary occlusion

Coronary occlusion refers to the partial or complete blockage of a coronary artery. This blockage can be caused by a thrombus (blood clot), spasm, or sclerosis (hardening of the arteries). Atherosclerosis, a condition where fats, cholesterol, and other substances build up in the inner lining of arteries, is a primary cause of coronary occlusion.12

When atherosclerosis affects the coronary arteries, it can reduce blood flow to the heart muscle, leading to chest pain (angina pectoris) or, if the occlusion is complete, a myocardial infarction (heart attack). Treatments for occlusive arterial disease aim to open or bypass the blocked vessel, including procedures like angioplasty with stenting or coronary artery bypass surgery.234
