Echouffo-Tcheugui JB, et al. - Following cardiac resynchronization therapy with defibrillator (CRT-D) implantation, researchers evaluated the connection between BMI and heart failure (HF) outcomes. They followed up with 18,922 Medicare beneficiaries with HF (aged ≥ 65 years) having first-time CRT-D between 2010 and 2013 in the National Cardiovascular Data Registry (NCDR) Implantable Cardioverter-Defibrillator Registry for 3 years after implantation. According to the findings, most elderly patients were overweight or obese who had HF receiving CRT-D. Being underweight was linked with a higher risk of death and hospitalization, but patients who were overweight and obese had a lower risk of death following CRT-D. No differences in rates of device-related complications within 90 days across BMI categories were found.
