A Case of Non-Q Myocardial Infaction in a Patient with Myocardial Bridging

Abstract

Myocardial bridging is defined as segmental engulfment of a major epicardial coronary artery by myocardial fibers, causing a systolic narrowing or milking effect of the coronary arterial segment. During systole, the intramuscular part of coronary artery is compressed by contraction of overbridging ventricular muscle, therefore blood flow distal to the lesion is impaired and angina pectoris or acute myocardial infarction may occur. We experienced a case of Non-Q myocardial infarction in a 42 years-old female patient with myocardial bridge at the proximal and middle part of left anterior descending coronary artery.
