Abstract

Myocardial injury is a recognized complication of acute pancreatitis, whereas myocarditis has only been occasionally reported and has not been systematically evaluated. We systematically reviewed PubMed literature published up to January 2024 for studies including both “myocarditis” and “pancreatitis” as keywords. Relevant data regarding patient characteristics and outcomes were collected and analyzed. A total of 31 patients from 31 independent studies were included. The etiology of pancreatitis was viral in 52%, bacterial in 20%, toxic in 16%, autoimmune in 9%, and idiopathic in 3%. 23% of patients were immunocompromised. Median high sensitivity-cardiac troponin T was 342 (IQR 73-890) ng/L and N-terminus-pro-brain natriuretic peptide was 11053 (IQR 1397-26150) pg/mL. The average left ventricular ejection fraction was 33±13%. Fulminant myocarditis, presenting with cardiogenic shock and/or malignant ventricular arrhythmias occurred in 48% of patients, more frequently in men than in women (P=0.026). Severe myocarditis occurred in 42% of edematous and 60% of necrotizing pancreatitis (P=0.56). No association was found between the severity of myocarditis and plasma levels of amylase (P=0.98) and lipase (P=0.83). The relative frequency of severe myocarditis was 80% in pancreatitis due to Leptospirosis, and 40% in pancreatitis due to viral infections. The mortality rate was 22%: 13% died during hospitalization and 9% after. Myocarditis is a potentially lethal complication of pancreatitis and is more frequently associated with viral etiology in immunocompromised individuals. Based on such findings, cardiac troponin measurements and an electrocardiogram are advisable to exclude myocardial involvement in selected patients. Confirmatory diagnosis and prognostic assessments should be based on cardiac magnetic resonance imaging.
