Benefits of Implantable Cardioverter-Defibrillator for Secondary Prevention in Patients With Organic Heart Disease.

ABSTRACT:

Background

Implantable cardioverter-defibrillators (ICD) are first-line treatment to prevent sudden cardiac death due to recurrent ventricular tachycardia and fibrillation (VT/VF). However, some patients with organic heart disease (OHD) die without ever receiving appropriate ICD therapy. This study aimed to identify predictors of death without appropriate ICD therapy in patients with OHD who received ICD or cardiac resynchronization therapy with a defibrillator (CRT-D) for secondary prevention.

Methods

We analyzed consecutive patients who received ICD/CRT-D for secondary prevention between 2000 and 2022. Patients without OHD or those alive without appropriate ICD therapy were excluded. The "no-benefit group" included patients who died or developed severe disability without a
