Acute myocardial infarction in a young adult with myocardial bridging and normal coronary arteries

Abstract

The authors present a case of a young adult with acute myocardialinfarction, attended at the Emergency Department of HospitalIsraelita Albert Einstein. Acute myocardial infarction caused bymyocardial bridge (intramyocardial tunneled coronary artery) is arare clinical entity. The finding of this condition in patients withnormal arteries (non-obstructed vessels) is uncommon; it isusually associated with extracardiac triggering factors. The casereported presented an acute myocardial infarction caused by amyocardial bridge as demonstrated in the clinical picture, ECGprogression, enzyme pattern (troponin, CKMB, TGO and LD) andventriculography.
