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). (Table
