To investigate the correlation between Short Form-36 (SF-36) and exercise capacity including: (1) metabolic equivalents measured by an exercise stress test (METs of EST), (2) peak oxygen consumption (VO2 peak), and (3) walking distances measured by a six-minute walk test (6MWT). SF-36, EST and 6MWT were estimated at the sixth week after coronary artery bypass graft (n=17) and percutaneous coronary intervention (n=13) patients. Pearson product-moment correlation was used to evaluate the relationship ofparameters. Physicalfunctioning scale ofSF-36showed moderate correlation with METs (r = 0.55, p<0.01),fair correlation with VO2 peak of 6MWT (r = 0.46, p<0.05) and walking distance (r = 0.43, p<0.05). Bodily pain showed fair correlation with METs (r = 0.40, p<0.05) and walking distance (r = 0.45, p<0.05). Socialfunctioningshowedfair correlation with METs (r = 0.38, p<0.05). Report-health transition showed fair correlation with METs (r = 0.38, p<0.05) and walking distance (r = 0.41, p<0.05). The physical domain ofSF-36 that comprised physicalfunction, role-physical, bodily pain and general health correlated with physical capacity ofthese post-operation groups (r = 0.49, p<0.001). Therefore, clinicians can use the SF-36 and 6MWTto evaluate functional capacity in addition to ESTand indirect calorimetry conveniently.
