Treadmill Exercise Stress Test-Induced Takotsubo Cardiomyopathy: A Case Report and Review of Literature

Abstract

Noninvasive stress testing is routinely indicated and preferable in the diagnosis of coronary artery disease. We present the case of a patient who developed Takotsubo syndrome/cardiomyopathy (TTS) as a result of an exercise stress echocardiography, as well as a literature review of comparable cases. An abnormal stress test necessitated coronary angiography, which revealed nonobstructive coronaries with apical left ventricular ballooning and a decreased ejection fraction (EF), both of which are concerning for TTS. The patient was medically managed with metoprolol and lisinopril, with improvement in the EF on the follow-up echocardiogram.
