All-cause mortality
The occurrence of all-cause death in ICM group was higher than in DCM group, while SCD and other cardiogenic deaths (including death due to malignant arrhythmia such as ventricular tachycardia, ventricular fibrillation, etc.) were not statistically different between the two groups. Kaplan-Meier multivariate Cox regression analysis showed that ICM group had higher cardiovascular mortality than DCM group, but there was no significant difference of the incidence of cardiopulmonary resuscitation or sustained ventricular tachycardia (VT).
