Abstract
BACKGROUND: The wearable cardioverter defibrillator (WCD) is a life-saving therapy in patients with high risk of arrhythmic death. We aimed to evaluate ventricular arrhythmia (VA) occurrence rate and compliance with the WCD during the first 90 days following myocardial revascularisation with percutaneous coronary intervention (PCI) in patients with left ventricular ejection fraction (LVEF) <30%. METHODS: From September 2015 to November 2016, clinical characteristics, WCD recordings and compliance data of the aforementioned subset of patients were prospectively collected. RESULTS: Twenty-four patients (men=20, 80%) were included in this analysis. Mean age was 56±10 years and mean LVEF at enrolment was 26.6±4.3%. During a mean wearing period of 3.0±1.3 months, two episodes of VA occurred in two patients (8.3%): one successfully treated with WCD shock and one with spontaneous termination. The mean and median daily use of the WCD was 21.5hours and 23.5hours a day, respectively. Eighteen patients (75%) wore the WCD more than 22hours a day. CONCLUSIONS: The rate of VA, during the WCD period use after myocardial revascularisation with PCI, was high in our study. Otherwise it underlined that patient compliance is critical during the WCD period use. Remote monitoring and patient education are keys to achieve good compliance.
