Reverse takotsubo cardiomyopathy presenting as abdominal pain: An atypical presentation

Abstract

Reverse takotsubo cardiomyopathy is the rarest variant of takotsubo cardiomyopathy. We present a case of reverse takotsubo cardiomyopathy presenting as abdominal pain likely due to non-occlusive mesenteric ischemia. A 58-year-old female presented with abdominal pain, nausea, vomiting, and diarrhea for 2 days. Upon presentation, she was normotensive but tachycardic. Her lactic acid level was 2.8 mmol/L and troponin-T was 0.62 ng/ml. The electrocardiogram showed non-specific ST changes. CT scan of abdomen revealed bowel wall thickening in transverse colon and splenic flexure. Patient was started on aggressive intravenous fluid therapy for possible infectious colitis.The next day, patient started becoming progressively more dyspneic, hypoxic, and hypotensive. A chest X-ray at that time showed signs of severe congestive heart failure. Echocardiogram revealed left ventricular ejection fraction of 20% with akinesis of proximal and mid-ventricular walls. Patient was intubated for hypoxic respiratory failure and started on milrinone infusion for acutely depressed cardiac function. Inotropes were weaned off the next day, and she was successfully extubated on day 4. Subsequently, gastrointestinal symptoms resolved. Cardiac catheterization was performed later during the hospitalization that showed normal coronary arteries. Repeat echocardiogram done 3 months later showed return of cardiac function to normal.
