Background and objective: The 6-minute walk test (6MWT) is a popular, practical and straightforward test that widely used to guide a cardiac rehabilitation program and assess exercise tolerance, therapeutic effect and prognosis. 6-minute walk distance (6MWD) varies with different factors. This research aimed to study the factors that affect 6MWD in post-cardiovascular surgery patients after discharge at Queen Sirikit Heart Center of the Northeast. Methods: Data and attractive factors collected from the medical records of the post-cardiovascular surgery patients during their first follow-up after discharge from Queen Sirikit Heart Center of the Northeast from May 1st, 2017 to April 30th, 2018. The statistical analysis applied to mean, standard deviation, correlation coefficient and stepwise multiple regression analysis. Results: 6MWD mean of 153 subjects was 276.05 ± 74.43 meters. The factors that relate to 6MWD are sex, height, maximum heart rate in the 6MWT, and the rate of perceived exertion before 6MWT. The shared factors in the prediction of 6MWD (r2 = 0.288, p < 0.001) are age, sex, and the rate of perceived exertion before 6MWT. Conclusions: The affected factors that could predict 6MWD in post cardiovascular surgery patients discharged from Queen Sirikit Heart Center of the Northeast are age, sex, and the rate of perceived exertion before 6MWT.
