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: -Most myocardial infarctions occurred in the right coronary artery (RCA; n=92, 44%) and left anterior descending artery (LAD; n=81, 39%) (Table 2). There was 1 thrombosis each in the left main and ramus intermedius segments.
Detailed explanation-3: -A heart attack is also called a myocardial infarction (MI). It happens when one or more parts of the heart muscle don’t get enough oxygen. That occurs when blood flow to the heart muscle is blocked. If the blood and oxygen supply is cut off, muscle cells of the heart begin to suffer damage and start to die (infarct).
