Myocardial bridging can cause acute anterior myocardial infarction even in the absence of significant atherosclerotic coronary artery disease, and may be successfully treated with medical management.
A 38-year-old male presented with an acute anterior myocardial infarction. Immediate cardiac catheterization revealed no evidence of angiographically significant atherosclerotic coronary artery disease, but there was a subtotal occlusion of the mid-left anterior descending coronary artery from myocardial muscle bridging. The patient did well with medical management. This review details myocardial bridging and its treatment.
Tauth et al. (1997) studied this question.
