Daughter, you broke my heart: accidental thrombosis at a muscular bridge.

Abstract

We report the case of a 59-year-old trained runner, who sustained an acute myocardial infarction, with residual effort angina, following extreme exertion while experiencing severe anxiety. Coronary angiography revealed that this patient had a myocardial bridge at the mid-left anterior descending artery, and an occlusive clot had developed at the proximal end of the muscular bridge. We discuss the possible relationships between the various circumstances of this sudden event. We argue that, under exceptional conditions, myocardial bridges can lead to myocardial infarction by clot formation.
