Severe pulmonary dysfunction linked to transient stunned myocardium mimicking AMI despite normal coronary arteries.
Case Report (n=1)
No
Severe pulmonary dysfunction can cause atypical stunned myocardium that mimics acute myocardial infarction.
Clinicians should consider pulmonary dysfunction in atypical stunned myocardium differentials; single case leaves open generalizability and causality.
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.

Kobayashi et al. (2002) conducted a case report in Stunned myocardium caused by severe pulmonary dysfunction (n=1). Severe pulmonary dysfunction was evaluated. Severe pulmonary dysfunction caused a transient, atypical stunned myocardium mimicking acute myocardial infarction in a 71-year-old man with normal coronary arteries.
