Atypical Stunned Myocardium Caused by Severe Pulmonary Dysfunction

Abstract

We present the case of a 71‐year‐old Japanese man suffering from severe dyspnea who showed abnormal left ventricular motion in cardiac echogram with ST‐T elevation in electrocardiogram, which at first was misdiagnosed as an acute myocardial infarction. Coronary angiography showed neither coronary obstructions nor spasms. The symptoms were transient and the patient soon recovered. We speculate that it is a specific type of atypical stunned myocardium caused by the great stress of severe pulmonary dysfunction.
