Baseline Characteristics of the Patients
Baseline characteristics of the included patients in each group were shown in Table 1 .Compared with patients in DCM group, ICM group were significantly older (p < 0.001) and the prevalence of hypertension (p<0.001) and diabetes (p = 0.033) in the ICM group was significantly higher than that in DCM group. LVEF (p = 0.002) were significantly higher than that of DCM patients and diastolic blood pressure (DBP, p = 0.015) were significantly lower than that of DCM patients. Other demographic variables were comparable between the two groups. NYHA classification, B-type natriuretic peptide (BNP) and systolic blood pressure (SBP) had no statistically significant difference. More percentage of people in the DCM group received CRT (37.7% vs. 12%, p = 0.009; Table 1 ). The large majority of patients in both groups received heart failure medications according to the ESC Guidelines while there was no significant difference except for P2Y12 receptor inhibitors (p <0.001) and statins (p = 0.002).
