What forms blood clots in an artery that supplies blood to the myocardium courseherp?

Blood clot in the coronary arteries( arteries of the heart), called Coronary thrombosis is caused mostly by deposits and build up of  low density cholesterol, fibrous tissues, and inflammatory cells. on the walls of the artery. Smoking, sedentary life style(lack of exercise),and hypertension are other causes..

Obesity is another causative condition for coronary thrombosis.

These deposits and build up coalesces in different parts  of the coronary  arteries; to form structures called  plaques. The latter may break down at this  arterial segments which leads top formation of blood clot. (thrombosis)

The clot results in the blockage of the arteries that  supplies    the affected site,  with blood containing  oxygen and nutrients. This leads to tissue hypoxia(lack of oxygen) to the cardiac muscles cells   of the myocardium  and therefore myocardial infraction.(HEART ATTACK)

In some cases  these clots are pumped out  of the heart to the cerebral arteries, due to proximity of the brain to the heart. In this case this can lead to stroke,
