| Popis: | Background Peak oxygen uptake (peak VO2) and heart rate reserve (HRR) are independent prognostic markers of cardiovascular disease. However, the impact of peak VO2 and HRR on long‐term prognosis after off‐pump coronary artery bypass grafting (OP‐CABG) remains unclear. Hypothesis To determine the prognostic impact of peak VO2 and HRR in patients after OP‐CABG. Results We enrolled 327 patients (mean age, 65.1 ± 9.3 years; male, 80%) who underwent OP‐CABG and participated in early phase II cardiac rehabilitation. All participants underwent cardiopulmonary exercise testing (CPET) at the beginning of such rehabilitation. Overall, 48 (14.6%) patients died during the median follow‐up period of 103 months. The non‐survivor had significantly lower levels of peak VO2 (10.6 ± 0.5 vs. 13.7 ± 0.2 ml/kg/min, p |
