…imperfect predictor of future myocardial infarction or sudden death. Lesions causing only mild obstruction may rupture, thrombose and occlude. Many acute myocardial infarctions arise from…

…that compresses the true lumen. The resulting reduction in coronary blood flow may produce myocardial ischaemia, acute coronary syndrome (ACS), myocardial infarction (MI), or, rarely…

…myocardial ischaemia caused by an acute coronary process. Myocardial injury leads to release of cardiac troponin, but troponin elevation is not specific for myocardial infarction…
