The diagnostic value of the six-minute corridor walk test in patients qualified to undergo vascular procedures
open access
Abstract
Material and methods: 51 patients were examined (mean age 60.5 ± 9.8). Claudication distance, maximum claudication distance and pre- as well as post-excercise heart rate, blood pressure and electrocardiogram were analysed. The results of the distance measurement were compared to the results of angiography.
Results: The walking test within the full time interval was completed by 14 patients. The patients were classified to the group I according to Ratschow classification. The remaining 37 patients finished the test before 6th minute of the test duration (group I - 8 pts., group II - 24 pts., III - 5 pts.). The results revealed that the decrease of the claudication distance correlated with the percentage of the arterial stenosis or occlusion (correlation r = –0.6945, p < 0.001). On the base of the heart rate and blood pressure changes as well as according to the EKG analysis, one patient was disqualified from the surgical treatment due to cardiological contraindications and in 6 patients significant hemodynamic changes were noticed (qualifying these patients to the high surgical risk group).
Conclusions: The six minute corridor walking test is an useful method in the cardiovascular evaluation in patients before vascular reconstructive surgery. The results of the study confirm the diagnostic value of the performed tests in PAOD patient assessment (especially for evaluation of functional capacity).
