Prognostic impact of peak oxygen uptake and heart rate reserve in patients after off-pump coronary artery bypass grafting.

ABSTRACT:

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 l
