Myocardial Infarction and Development of Heart Failure
Acute myocardial infarction suddenly occurs by total occlusion of coronary artery and the myocardium where oxygen is supplied by the occluded coronary artery gets necrosis. The infarcted necrotic cardiac tissue is then replaced by the scar tissue and the necrotic myocardial wall thickness becomes thin and the LV cavity diameter becomes enlarged, which is called LV remodeling, and then heart failure is accelerated.
