A Myocardial Infarction Following a Mild Case of COVID-19 in a 26-Year-Old Male.

A well-known complication of COVID-19 is hypercoagulability in both the venous and arterial circulation. Most cases of hypercoagulability-related complications have been described in hospitalized patients with severe diseases and multiple comorbidities. However, this report outlines a case of myocardial infarction in a young patient with no prior medical history after only a mild course of COVID-19. His symptoms resolved after a mild 12-day illness course that did not require hospitalization or supplemental oxygen. Three days after the resolution of his symptoms (15 days after testing positive), the patient presented to the emergency department with crushing chest pain and was found to have complete thrombotic occlusion of his left anterior descending artery. Hypercoagulability in COVID-19 patients is suspected to be caused by vascular endothelial injury and cytokine storm. This has been demonstrated in the arterial and venous circulation, as seen in histopathology samples as well as increased incidence of acute limb ischemia in COVID-19 patients. Additionally, COVID-19 is known to have myocardial involvement, as demonstrated by elevations in cardiac enzymes and cardiac imaging findings that may persist months after initial infection. Those affected by COVID-19 may have dangerous cardiovascular complications that persist after the resolution of the acute viral illness.
