Abstract
Objective: To investigate the relationship among metabolic equivalents of an exercise stress test (METs of EST), demographic parameters (age, body weight, height, BMI), peak oxygen consumption (VO2 peak), and six-minute walk distances (6MWD) determined from a six-minute walk test (6MWT).
Material and Method: Exercise capacity was estimated by a 6MWT and EST at the sixth week post operation in post coronary artery bypass graft (post CABG, n = 17) and post percutaneous coronary intervention (post PCI, n = 13) patients.
Results: METs of EST showed: high correlation (p < 0.01) with VO2 peak of 6MWT (r = 0.94), 6MWD (r = 0.92); muscle
strength (r = 0.78), moderate correlation (p < 0.01) with height (r = 0.53); negative correlation with age (r = -0.50). Low
correlation was found (p < 0.05) with step length (r = 0.43), and weight (r = 0.38). No correlation was found among METs of EST and rating perceived exertion (RPE) of EST and 6MWT. The multiple linear regression equation for explaining METs of EST is as follows: METs of EST = -2.94+0.02 (6MWD), (r = 0.923, R2 = 0.85, p < 0.001).
Conclusion: The 6MWT may possibly be used as an alternative choice for estimating energy expenditure to design exercise programs for these post operation groups.
