A 30-year-old man was admitted with severe chest pain and electrocardiographic evidence of myocardial infarction. Subsequent angiography revealed myocardial bridging of the middle third of the left anterior descending coronary artery and no evidence of coronary atherosclerosis. In the absence of other risk factors, circumstantial evidence points to a possible etiological role of myocardial bridging in the ischemic event in our patient.
