Association of BMI with adherence and outcome in heart failure patients treated with wearable cardioverter defibrillator

CONCLUSIONS: Obese patients exhibited significantly greater improvement in LVEF, which was associated with reduced mortality. Adherence to WCD therapy was excellent across all BMI groups. ICD implantation occurred in 40.3% of patients, with similar WCD shock rates and arrhythmic events across BMI groups. An obesity paradox was observed, with obese patients demonstrating significantly lower rehospitalization rates due to cardiovascular causes and reduced mortality at …
