ABSTRACT
Acute viral myocarditis is a serious complication of viral infectious diseases, including coronavirus disease 2019 (COVID-19). To better understand the pathogenesis of acute viral myocarditis, we retrospectively analyzed the incidence and prognostic significance of hypocalcemia among patients with acute myocarditis, most of whom were considered to have acute viral myocarditis. We retrospectively reviewed the demographic and clinical data of patients with clinically confirmed acute myocarditis treated in our hospital over a 13-year period from 2006 to 2019, including laboratory results, cardiac imaging findings, and clinical outcomes. These data were compared between lower, middle, and higher calcium groups depending on the minimum calcium level measured during hospitalization. Among the 288 patients with acute myocarditis included, the hypocalcemia group (lower calcium group) had poorer clinical and laboratory results, received more medications and device support, and experienced poorer outcomes, including heart failure, arrhythmias, and death. Specifically, the left ventricular ejection fraction was significantly lower, and the length of hospital stay was significantly longer in the hypocalcemia group than in the other two groups. Furthermore, the incidence rates of atrioventricular block, ventricular tachycardia/ventricular fibrillation, cardiogenic shock, and mortality were significantly higher in the hypocalcemia group. Multivariate Cox regression analysis identified hypocalcemia as an independent risk factor for 30-day mortality in patients with acute myocarditis. In conclusion, the clinical evidence provided by the present study indicates that hypocalcemia is a risk factor for poorer outcomes in patients with acute myocarditis that should be considered carefully in the diagnosis and treatment of these patients.
