A Unique Case of COVID-19-related Acute Coronary Thrombosis Complicated by Severe Hypokalemia.

We report the case of a 52-year-old white male who was recently diagnosed with symptomatic coronavirus disease-2019 (COVID-19) and presented to the hospital with ventricular tachycardia/ventricular fibrillation cardiac arrest, ST elevation myocardial infarction, and profound hypokalemia. The patient was successfully treated with primary percutaneous coronary intervention and concurrent aggressive potassium repletion. To the authors' knowledge, this is the first case of COVID-19 presenting not only with an acute coronary thrombosis but also severe hypokalemia, both of which contributed to his cardiac arrest. The association of COVID-19 with acute coronary thrombosis, including the challenges surrounding the diagnosis and management in this patient population, is discussed. Additionally, the effect of COVID-19 on the renin-angiotensin-aldosterone system is reviewed with a focus on hypokalemic presentations.
