…narrowing of the left main coronary artery, which supplies the left anterior descending and left circumflex coronary territories. Because these vessels perfuse a large proportion…

…can aid in diagnosing ischemia and infarction and guide appropriate management strategies. For instance, administering nitroglycerin to alleviate ischemic chest pain may lead to hemodynamic…

…function. The abnormalities affect the myocardial area supplied by the arteries distal to the occlusion or stenosis. If the ischemia persists for 20 minutes, myocardial…

…the systemic circulation), and therefore it faces the highest workload; for the same reason, the left ventricle has the highest oxygen demand. The right ventricle…

…Consequently, the myocardium supplied by the occluded artery becomes ischemic. Ultimately this results in myocardial necrosis (death of myocytes) which can be detected by elevated…
