Relation of Body Mass Index to Long-Term Survival after Cardiac Resynchronization Therapy

Obesity confers a paradoxical survival benefit among patients with heart failure (HF), but this obesity paradox has not been well established in patients undergoing cardiac resynchronization therapy with a defibrillator (CRT-D). We sought to determine the impact of body mass index (BMI) on long-term survival in patients with HF following CRT-D. We identified 113 patients implanted with CRT-D at our institution from 5/2002-11/2003. Patients were divided into three categories by pre-implant BMI (kg/m2): normal-weight (BMI
