Cardiac resynchronization therapy combined with coronary artery bypass grafting in ischaemic heart failure patients: long-term results of the RESCUE study
The authors performed a randomized control study of 178 patients with heart failure and systolic dyssynchrony who were accepted for CABG, randomizing the participants into two groups: CABG alone (n=87) and CABG + concomitant epicardial CRT (n=91). CRT was activated postoperatively. At a mean follow-up period of 55 months, the mortality rate of the CABG group was 36% and that of the CABG + CRT group was 15%. Moreover, all-cause mortality, cardiac death, and hospital readmissions were significantly lower for the CABG + CRT group.
It is known that not all patients with potential indications for CRT undergoing CABG will meet the criteria for CRT postoperatively. The question is whether performing CRT at the time of CABG in all such patients is a cost-effective strategy.
