Abstract: Purpose: Advanced age is associated with increased mortality and morbidity in patients undergoing coronary artery bypass grafting (CABG), which may be a consequence of cardiopulmonary bypass. Thus, off-pump surgery may have an increased benefit in elderly patients. We aim to evaluate cardiac events and long-term clinical outcomes in elderly patients with stable coronary artery disease and preserved left ventricular ejection fraction undergoing off-pump and on-pump CABG. Methods: The MASS III was a single-center randomized trial that evaluate 308 patients with stable coronary artery disease and preserved ventricular function assigned for off-pump (n=155) or on-pump (n=153) CABG. Of this, 176 (58,3%) patients had 60 years or older at the time of randomization (of-pump=90 and on-pump=86). Primary composite end points were death, myocardial infarction, further revascularization (surgery or angioplasty), or stroke. Results: The two randomized groups were well-matched for baseline demographic, clinical, and angiographic characteristics. The mean age was 67,2 ( ± 5,0) years. After 5-year follow-up, there were no significant differences between on- pump and off-pump groups in the composite end points: 27,9% vs 21,1% (hazard ratio 1.17, 95% CI 0.87 to 1.59; P=0.29) Figure 1. Six patients (7.0%) died in the on-pump group compared with 10 (11.1%) in the of-pump group (hazard ratio 0.78, 95% CI 0.47 to 1.29; p=0.33). On-pump patients had a higher incidence of postoperative stroke or myocardial infarction: 13 (15.1%) vs 5 (5,6%); p=0,036. Conclusions: Patients undergoing off-pump surgery had a lower incidence of in hospital stroke or myocardial infarction. This finding did not add benefit in clinical outcomes at 5-years follow-up.
