Detailed explanation-1: -In coronary artery disease, one or more of the heart (coronary) arteries are blocked. This is usually due to cholesterol-containing deposits called plaques. Plaques can narrow the arteries, reducing blood flow to the heart. If a plaque breaks open, it can cause a blood clot in the heart.
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: -The LAD artery is the most commonly occluded of the coronary arteries. It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system.
