Long‐Term Survival in Patients Treated with Cardiac Resynchronization Therapy: A 3‐Year Follow‐Up Study from the InSync/InSync ICD Italian Registry

Abstract

During long-term (3 years) follow-up after CRT, total mortality rate was 10%/year. The outcome of ischemic patients was worse mainly due to a higher rate of death from progressive heart failure. Ischemic etiology along with NYHA class IV was identified as predictors of death. Benefits of CRT in terms of clinical function and echocardiographic parameters persisted at the time of long-term follow-up.
