Adherence
The wear time of WCD was comparable in males with 21.1±4.3 and female
group with 21.5±4.4 hours/days, the rate of compliance was revealed in
77% of male and 84.5% of female participants, there were no
significant differences in this regard. One observational study has
presented a similar adherence rate with daily use of 23 h per day in
6043 patients [19]. The wear time in the VEST trial was 18 h, also
less than the wear time in our patients [8]. Most cases of death
occurred in patients who were not using the WCD [8]. In this regard,
one important and possible cause for death was non-compliance in wearing
the WCD. However, suffering from cardiac arrest during the index MI, and
an increase of creatinine were independent predictors for a high WCD
wearing time [20]. In addition, the indication for WCD in one large
cohort was equivalent in accordance with our study concerning the
different number of cases including ICM or DCM, genetic or congenital
disease, ICD explanations, or myocarditis [19]. In our quartile age
analysis, adherence was more observed in older as compared to adult
patients. In this regard, the WEARIT-France study showed that younger
age was associated with lower compliance [21].
