However, ICM was more observed in 52-72- and 73-91-years old groups as compared to 14-51 years old group, respectively (48.3% in 73-91 years old group vs. 18.6% in 14-51 years old group; p<0.001) (44.8%in 52-72 years old group vs. 18.6% in 14-51 years old group; p<0.001). On the other hand, NICM was more revealed in adult as compared to older patients (57.8% in 14-51 years old group vs. 43.7% in 52-72 years old group; p=0.003) (57.8% in 14-51 years old group vs. 36% in 73-91 years old group; p<0.001). Devices were more implanted after WCD wearing in older patients as compared to adult patients (40.7% in 73-91 years old group vs. 26.1% in 14-51 years old group; p=0.005). The compliance was observed more in older as compared to adult patients (87.8% in 73-91 years old group vs. 68.3% in 14-51 years old group; p<0.001). At 3-months follow-up, LVEF was 39.34%±14.24 in adult group and 36.24%±11.72 in older patients; p=0.03.
