Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV2), emerging in Wuhan, China and developing into a pandemic with rapidly emerging cardiovascular manifestations

Mesalamine is often used in the treatment of inflammatory bowel disease (IBD). Mesalamine-induced cardiotoxicity has been reported in the literature and is a rare entity. The mechanism of cardiotoxicity remains unclear, however, it is believed to be due to a humoral-mediated hypersensitivity reaction. Patients with mesalamine-induced cardiotoxicity could present with a wide range of cardiovascular symptoms ranging from mild chest pain and shortness of breath (SOB) to cardiogenic shock secondary to left ventricular systolic dysfunction. Symptoms could be associated with elevation in cardiac biomarkers and electrocardiogram (EKG) changes including ST-segment or T-wave abnormalities. We report a case of mesalamine-induced myocarditis in a young athlete presenting with chest pain 10 days after mesalamine therapy was initiated for recently diagnosed Crohn’s disease. Workup was significant for elevated cardiac biomarkers. The diagnosis was confirmed with cardiovascular magnetic resonance imaging (CMR). Immediate cessation of the medication resulted in resolution of symptomatology and normalization of cardiac biomarkers over a 48-hour period. Mesalamine-induced cardiotoxicity is a rare, yet serious side effect that necessitates medical community awareness. CMR is the confirmatory diagnostic modality of choice.
