Key result
The 6-minute cycle test demonstrated good repeatability with a coefficient of variation of 4.2% and detected significant changes after 8 weeks of exercise.
Why the study?
Does the 6-minute cycle test provide a repeatable and useful measure of outcome changes in PCI patients undergoing cardiac rehabilitation?

Does the 6-minute cycle test provide a repeatable and useful measure of outcome changes in PCI patients undergoing cardiac rehabilitation?
The 6-minute cycle test is a repeatable and useful tool for measuring collective and individual exercise capacity outcomes in patients undergoing cardiac rehabilitation.

May support 6-minute cycle test for rehab monitoring in PCI; leaves open need for prospective validation.
Purpose: To determine the repeatability of the 6-minute cycle test (6MC), and the usability of the 6MC as a measure of outcome changes in a cardiac rehabilitation programme (CR). Method: Subjects were 49 PCI patients, aged 43–68 years, participating in a phase II CR programme. Repeatability: Each patient performed a 6MC test and retest on 2 separate days. The workload of the 6MC was determined by an incremental ergometer cycle test prior to the 6MC test. Outcome: 36 of the initial 49 patients performed the 6MC tests after 8 and 12 weeks of exercise and again 1 month after completing the CR programme. Results: The coefficient of variation (CV) was 4.2% for the 6MC. The 95% CI for the difference between test–retest were for the 6MC [− 0.185 to 0.285] km., p = 0.044. Data showed significant changes between baseline and 8 weeks of exercise, p < 0.01. Data revealed individual improvements exceeding the 95% CI of the patients. Conclusion: 6MC showed to be able to determine collective and individual outcomes in CR. Further studies are necessary to address the relation between VO2 max test and results of the 6MC test.

Villumsen et al. (2013) conducted an observational in PCI patients in cardiac rehabilitation (n=49). 6-minute cycle test (6MC) was evaluated on Difference between test-retest (95% CI -0.185 to 0.285, p=0.044). The 6-minute cycle test demonstrated good repeatability with a coefficient of variation of 4.2% and detected significant changes after 8 weeks of exercise.
