Acute cholecystits leading to ischemic ECG changes in a patient with no underlying cardiac disease

Abstract

Although chest pain with ST-segment elevation is often indicative of cardiac ischemia, it has also been described with surgical conditions such as acute cholecystitis. We report the case of a 34-year-old Caucasian female who was referred with symptoms consistent with acute cholecystitis. An electrocardiogram (ECG) showed unexpected changes with inferolateral ST-segment elevation indicative of an inferolateral myocardial infarct. Further investigations and analysis of the results along with the clinical picture meant an acute cardiac event was excluded. Gallstones were seen on ultrasound and an inflamed gallbladder, consistent with acute cholecystitis, was confirmed at laparoscopic cholecystectomy. This led to the resolution of her symptoms and a return to the isoelectric baseline of the ST segments on the ECG. Five previous cases of cholecystitis induced ECG changes have been described in the literature. This case describes the youngest patient with no previous cardiac disease. We review the literature and suggest the pathophysiological mechanism to explain these findings. When the initial diagnostic interventions for chest pain with ST-segment elevation do not yield the expected results, an alternative diagnosis such as cholecystitis should be considered. © 2011 by JSLS, Journal of the Society of Laparoendoscopic Surgeons.
