Coronary vasospasm is an underdiagnosed cause of myocardial infarction in the absence of obstructive coronary artery disease. Systemic inflammation is one of several triggers associated with coronary vasospasm. We report the case of a 47-year woman incidentally found to be COVID-positive (RT-PCR) during evaluation of constitutional symptoms and breast cellulitis. Later in the hospitalization, she developed sudden-onset typical angina at rest;12 lead EKG showed inferolateral ST-elevations. Urgent coronary angiogram showed nitrate-responsive subtotal focal occlusions in the right coronary and circumflex arteries. In the absence of sepsis, it is difficult to attribute coronary vasospasm solely to cellulitis. Focal coronary artery spasm mimicking ST-elevation myocardial infarction successfully managed solely with intracoronary nitroglycerine in an incidentally COVID-positive patient adds to the diverse manifestations of COVID infection. The exact mechanism of focal, as opposed to diffuse coronary vasospasm is unclear. Copyright© South Dakota State Medical Association.
