Reversible Takotsubo Syndrome Complicated With Acute Thromboembolic Stroke Co-Occurring With Cola-Induced Severe Hypokalemia.

Takotsubo syndrome (TTS) is a poorly understood phenomenon that manifests as reversible myocardial damage. Despite the overall benign course of TTS, acute complications and significant mortality and morbidity are frequently encountered. However, the risk factors for developing such complications are not well determined. We present a case of reversible TTS within 48 hours after correction of cola-induced hypokalemia complicated by thromboembolic stroke. We present the patient's clinical presentation with imaging studies and discuss the case in light of related literature. A 62-year-old woman with a longstanding history of inadequate oral intake and excessively sweetened cola soft drinks consumption. Presented with progressive symmetrical quadriparesis and found to have severe hypokalemia with rhabdomyolysis, elevated troponin, and acute left ventricular dysfunction. The patient was diagnosed with TTS and hypokalemic paralysis. Her hospital course was complicated with an acute thromboembolic stroke of bilateral occipital lobes and left cerebellum. Takotsubo cardiomyopathy was reversible 48 hours after correction of severe hypokalemia. Cardiac ischemic workup was negative for any evidence of myocardial ischemia. In this presented case, TTS was revisable within 48 hours after the correction of cola-induced hypokalemia. However, patients with similar presentations might have a higher risk for in-hospital thromboembolic complications of TTS.
