Clinical Characteristics and Outcomes of Older Cardiac Resynchronization Therapy Recipients Using a Pacemaker versus a Defibrillator

Abstract

Higher all-cause mortality in older CRT-P versus CRT-D patients is largely explained by baseline clinical and demographic differences between the two groups, which are likely the drivers of device selection in real-world clinical practice, where the published guidelines remain ambiguous. There is a need for randomized studies to determine optimal CRT device selection.
