(6MWT) was widely used to assess the patient’s status
after cardiac surgery due to its feasibility. But the
Six-minute walk distance (6MWD) studies 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.
