Even minor weight loss is associated with worse health outcomes among patients implanted with a certain type of defibrillator known as cardiac resynchronization therapy with defibrillator (CRT-D), according to research presented at the American College of Cardiology’s 62nd Annual Scientific Session. People with symptoms of heart failure who have an implantable CRT-D device may believe that losing weight will ultimately improve their long-term health outcomes. However, in the first study to look at weight loss and subsequent health outcomes among patients with a CRT-D, researchers found the opposite may be true.
