Acute Myopericarditis with Crohn's Disease Flare-up

Cardiac involvement is rare in inflammatory bowel disease (IBD) but can occur as a complication of either the disease itself or drug therapy. We describe an interesting clinical scenario of acute myopericarditis during Crohn's flare-up. A 37-year-old patient with severe Crohn's disease started having multiple bloody bowel movements associated with abdominal pain. These symptoms were attributed to Crohn's disease flare-up, prompting the addition of steroids and an increase in the dose of mesalamine without any significant relief. Two weeks later, he presented to the emergency department with pleuritic chest pain. Electrocardiogram (EKG) revealed ST segments elevation in leads I and aVL. Laboratory work revealed elevated troponin I of 1.82 ng/mL, with increased erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) of 121 mm and 180.1 mg/L, respectively. Cardiac magnetic resonance imaging (MRI) revealed early gadolinium enhancement consistent with myocarditis. The patient was started on colchicine with an increase in the dose of steroids, resulting in clinical improvement. The patient reported having similar chest pain during a previous episode of Crohn's disease flare-up, suggesting underlying IBD as the likely etiology.
