…coronary artery (LMCA) occlusion is a rare but catastrophic manifestation of acute coronary syndromes. The LMCA supplies a large myocardial territory through the left anterior…

…cardiologists – particularly interventional cardiologists – this knowledge is of critical importance as they must be able to directly pinpoint where the coronary artery occlusion is located…

…spasm may account for the ischaemia. STEMI usually results from rapid thrombotic occlusion of a previously atherosclerotic coronary artery. Slowly progressive severe stenoses are less…
