Follow-Up
At baseline, the mean LVEF was comparable in both groups (29.5%±10.98% in males vs. 30.2%±12.2% in females; p=0.55). At follow-up, the mean LVEF increased during 3-6 months to 37.1%±12.1% in males and 37.95%±12.1% in females; p=0.49. The improvement of LVEF was numerically observed in both groups, more in females as compared to males (51.9% vs. 44.7%; p=0.16). The incidence of device implantation was comparable in both groups (35.1% in males vs. 31.8% in females; p=0.37). The wear time of WCD was similar in both groups, 21.1±4.3 hours/days in males as compared to 21.5±4.4 hours/days in females; p=0.27, and documented in days 62.6±44.3 days in males in comparison to 56.5±39 days in females; p=0.15. The rate of appropriate shocks was similar in both groups, 2.4% in the male and 3.9% in the female group; p=0.07, with a higher tendency in females, table 1. In addition, the rate of mortality was comparable in both groups (6.8% in males vs. 9.7% in females; p=0.55)
