概要	Cardiac resynchronization therapy (CRT) can decrease mortality and morbidity in selected heart failure patients with impaired left ventricular (LV) function, and a wide QRS complex. However, not all patients benefit from this therapy. To improve outcomes of CRT patients, further evaluation for prognostic factors will be required. We evaluated 401 consecutive Japanese patients (mean age 60±14 years, 73% men, 19% ischemic) who underwent CRT between 2001 and 2013. During the mean follow-up of 35±31 months, 96 patients (24%) died, 23 patients (6%) received LV assist device (LVAD) and 7 patients (2%) received heart transplantation. Kaplan-Meier curves of probability of freedom from death, transplantation, or LVAD implantation after CRT implantation were shown in Figure. Multivariate analysis showed that renal dysfunction (defined as estimated glomerular filtration rate <60ml/min/1.73m2) as well as non-responder (defined as a reduction ≥15% in LV end-systolic volume) was independently associated with mortality. (Table) Prognostic factors including renal dysfunction is important to identify therapeutic targets in order to improve mortality in the real world patients with CRT.
