Discussion
We present the clinical outcome including mortality rate in WCD patients divided into male and female groups up to 2 years. The main findings of the study are (1) The improvement of LVEF was revealed in both groups; (2) Mortality rate was similar in both groups; (3) The wearing time is comparable in male and female participants, but the appropriate shock rate tended to be higher in females as compared to males.
The WCD may be considered in selected patients with a high risk of SCD, if the implantation of conventional ICD is temporarily contraindicated (e.g. poor LVEF after acute myocardial infarction until LV function improves, before heart transplantation) [14]. Therefore, the American Heart Association (AHA), American College of Cardiology (ACC), Heart Rhythm Society (HRS), and European Society of Cardiology (ESC) provide class II, level of evidence C for the use of WCD in these selected patients [15, 16].
