14 Jan 2015 In most cases of AMI and in a majority of cases of SCD, the underlying pathology is acute intraluminal coronary thrombus formation within an epicardial coronary artery leading to total or near-total acute coronary occlusion. This article summarizes our current understanding of the pathophysiology of these

This formula represents the two key components of myocardial oxygen demand. The Pathogenesis of the Atherosclerotic Plaque: Atherosclerosis is the main cause of coronary artery disease.

Ischemic heart disease: a condition in which imbalance between myocardial oxygen supply and demand, most often caused by atherosclerosis of the coronary arteries, results in myocardial hypoxia and accumulation of waste metabolites.
