AbstractFulminant myocarditis is a severe cardiac emergency that may lead to death if effective cardiopulmonary supports are not provided. This study aimed to evaluate the prognostic predictors in patients with fulminant myocarditis.We retrospectively analyzed the clinical characteristics, complications, laboratory findings, treatments, as well as electrocardiographic and echocardiographic data of 73 consecutive subjects diagnosed with fulminant myocarditis from June 2012 to June 2016. Logistic regression analysis was used to identify the independent predictive factors of nonsurvivor fulminant myocarditis.Ten patients and 63 patients were assigned to the nonsurvivor and survivor fulminant myocarditis groups, respectively. Patients in the nonsurvivor fulminant myocarditis group had higher heart rates; were more likely to develop clinical complications and supraventricular tachycardia (SVT); and had higher serum creatinine (Scr) level, and had higher white blood cell (WBC) counts, and lower abbreviated estimated glomerular filtration rates (eGFR) than the patients in the survivor fulminant myocarditis group. Moreover, we observed larger left atrium dimension (LAd), larger left ventricular end systolic dimensions, and lower left ventricular ejection fraction in the patients from the nonsurvivor fulminant myocarditis group than in those from the other group. A logistic regression model was constructed and demonstrated that eGFR and LAd were 2 independent predictors of mortality in patients with fulminant myocarditis.Higher heart rates, higher incidences of clinical complication, SVT, higher admission levels of Scr and eGFR, higher WBC counts, higher Scr and eGFR at stage of most severe renal damage, and abnormal echocardiographic findings were associated with high risk of mortality in patients with fulminant myocarditis. The major finding was that eGFR and LAd were independent predictors for in-hospital mortality in patients with fulminant myocarditis.
