BACKGROUND Fulminant myocarditis is the critical form of myocarditis that is often associated with heart failure, malignant arrhythmia, and circulatory failure. Patients with fulminant myocarditis who end up with severe multiple organic failure and death are not rare.AIM To analyze the predictors of in-hospital major adverse cardiovascular events(MACE) in patients diagnosed with fulminant myocarditis.METHODS We included a cohort of adult patients diagnosed with fulminant myocarditis who were admitted to Beijing Anzhen Hospital from January 2007 to December2017. The primary endpoint was defined as in-hospital MACE, including death,cardiac arrest, cardiac shock, and ventricular fibrillation. Baseline demographics,clinical history, characteristics of electrocardiograph and ultrasonic cardiogram,laboratory examination, and treatment were recorded. Multivariable logistic regression was used to examine risk factors for in-hospital MACE, and the variables were subsequently assessed by the area under the receiver operating characteristic curve(AUC).RESULTS The rate of in-hospital MACE was 40%. Multivariable logistic regression analysis revealed that baseline QRS duration > 120 ms was the independent risk factor for in-hospital MACE(odds ratio = 4.57, 95%CI: 1.23-16.94, P = 0.023). The AUC of QRS duration > 120 ms for predicting in-hospital MACE was 0.683(95%CI: 0.532-0.833, P = 0.03).CONCLUSION Patients with fulminant myocarditis has a poor outcome. Baseline QRS duration is the independent risk factor for poor outcome in those patients.
