摘要: Objectives This study aimed to investigate the effect of both history intermittent atrial tachyarrhythmias (IAT) and in-trial IAT on risk heart failure (HF) or death comparing cardiac resynchronization therapy with defibrillator (CRT-D) implantable cardioverter-defibrillator (ICD) treatment in mildly symptomatic HF patients left bundle branch block (LBBB). Background Limited data exist regarding benefit CRT-D IAT. Methods The reducing HF/death was evaluated using multivariate Cox models incorporating presence of, respectively, a at baseline time-dependent development during follow-up 1,264 LBBB enrolled MADIT-CRT (Multicenter Automatic Defibrillator Implantation Trial With Cardiac Resynchronization Therapy) study. Results overall beneficial versus ICD not significantly different between without (HR: 0.50, p = 0.028, HR: 0.46, Conclusions In study, clinical attenuated by prior tachyarrhythmias.
