Detailed explanation-1: -Most myocardial infarctions are due to underlying coronary artery disease, the leading cause of death in the United States. With coronary artery occlusion, the myocardium is deprived of oxygen. Prolonged deprivation of oxygen supply to the myocardium can lead to myocardial cell death and necrosis.
Detailed explanation-2: -Angina, or chest pain and discomfort, is the most common symptom of CAD. Angina can happen when too much plaque builds up inside arteries, causing them to narrow. Narrowed arteries can cause chest pain because they can block blood flow to your heart muscle and the rest of your body.
Detailed explanation-3: -The heart is a muscle, and-like any other muscle-it needs oxygen-rich blood. Chronic coronary total occlusion (CTO) occurs when a buildup of plaque blocks the coronary artery for more than 90 days, starving your heart of oxygen. Left untreated, CTO can cause chest pain, unusual fatigue, and lifestyle restrictions.
