Survival analysis
Kaplan-Meier survival analysis revealed that the incidence of cardiovascular death during the follow-up period in the ICM group was higher than that in the DCM group (p = 0.049; Figure 1 ). After adjusted for age, LVEF, course of heart failure, NYHA classification, and history of diabetes. Cox regression analysis showed that cardiogenic mortality in ICM group was higher than that in DCM group. (Table 3 )
