The coronavirus disease (COVID-19 or SARS-CoV-2) pandemic has brought the global community to a halt. A return to normalcy is dependent on effective reopening strategies that encourage herd immunity through the implementation of vaccines. Cardiopulmonary inflammation has been reported in SARS-CoV-2 infection, independent of the severity, mainly amongst the juvenile population. Cardiovascular involvement following SARS-CoV-2 infection is associated with higher mortality and morbidity. Cardiovascular complications following COVID-19 vaccination have been documented as less severe, with no link between cardiovascular injury and death. This case report describes the presentation of an otherwise healthy 18-year-old male who experienced retrosternal chest pain after receiving a first dose of the mRNA-1273 vaccine. The patient had a negative polymerase chain reaction (PCR) test for COVID-19 infection. An electrocardiogram revealed diffuse ST elevation and PR segment depression, with increased inflammatory markers consistent with pericarditis. Elevation of troponin (16 ng/mL), evidence of borderline reduced ejection fraction (50-55%), and global left ventricular hypokinesis were suggestive of myopericarditis. Infectious and autoimmune studies were negative. The patient was treated mainly with non-steroidal anti-inflammatory drugs and colchicine, which resulted in a significant improvement of clinical symptoms. As the administration of emergency COVID-19 vaccines continues worldwide, it is of paramount importance to be aware of possible adverse events, including those affecting the cardiovascular system.
