Abstract

Background and objectives:  Six-minute walk test (6MWT) was widely used to assess the patient’s status after cardiac surgery due to its feasibility. But the 6MWD studied in Thailand trended to have shorter lengths than of western countries. It could not be applied to Thais. And the data regarding 6MWD after surgery of the elderly patients in Thailand was lacking. This study aimed to evaluate the average distance of 6MWT in cardiac-surgery elderly to assess the patient’s capability and follow up.

Methods: The data included the age, gender, types of surgery, risk stratification, and 6MWD of cardiac-surgery elderly who visited the rehabilitation department were collected. Then the mean value of 6MWD was calculated, and the correlation of 6MWD among each factor were analyzed.

Results: 98 patients with mean age of 67 years were included in the study, 55 patients underwent CABG, and 43 patients underwent valvular surgery. The overall mean 6MWD was 209.7±78.9 meters. 6MWD was significantly different in sex [95%CI (-65.4)-(-0.5), p=0.047] and type of surgery [5.6-67.8, p=0.021]. 

Conclusion: The normal 6MWD in Thai cardiac surgery elderly patients was 194-225 meters. This number could be used to represent the patient’s capability and further cardiac rehabilitation program.
