UnlabelledDetermination of patient's functional status in early postoperative period is a delicate task, because of its general health status. Measures that can be used for that purpose are walk tests and functional status questionnaires.ObjectiveTo determine correlation of different functional tests administered preoperatively and two minute walk test (2MWT) done postoperatively. To detect predictors of early functional recovery measured with two minute walk test.MethodWe examined ninety eight patients hospitalized for an elective coronary artery bypass graft surgery in February and March 2008. Functional status was assessed preoperatively using Duke Activity Status Index questionnaire (DASI), generic health related quality of life questionnaire and two minute walk test. Prior to discharge from the hospital, two minute walk test was repeated along with VAS for intensity of pain. Statistical analyze was done using Pearson's correlation coefficient, T test and multivariate regression analysis.ResultsDistance walked in 2 minutes decreased significantly postoperatively (p < 0.001). There was significant correlation between DASI and SF -12 preoperatively (r = 0.6 p < 0.001) and DASI preoperatively with 2MWT postoperatively (r = 0.4 p < 0.001). 2MWT postoperatively showed good correlation with intensity of pain (r = -0.42 p < 0.001) and age (r = -0.35 p < 0.001). There were no significant correlation with comorbidity, number of bypasses or postoperative complications. Multivariate regression analysis showed that the age was the strongest independent predictor of functional recovery (beta = - 0.33 < 0.05p) and that values of DASI preoperatively had moderate importance in prediction of functional status(beta = 0.238 p < 0.06).Conclusion2MWT was sensitive to change postoperatively. Significant correlation of 2MWT postoperatively with DASI preoperatively, age and VAS, as well as prediction capacity of age and DASI, gives us possibility to utilize those parameters in early rehabilitation program in order to achieve maximal functional recovery of patients.
