Overview

Repeat 6MWT gains limited to higher baseline performers; leaves open optimal protocols in stable CHF.

Structured PICO

Does repeat performance of 6-minute walk tests in patients with chronic heart failure relate to between-test interval or baseline performance?

P
Population
88 participants with stable chronic heart failure entering into heart failure rehabilitation programmes, mean age 65 ± 14 years, 45 females.
I
Intervention
Second 6-minute walk test performed with randomly allocated inter-test intervals between 15 and 90 minutes.
C
Comparator
First 6-minute walk test.
O
Outcome
Change in distance walked between the first and second 6-minute walk tests.surrogate

A repeat 6-minute walk test in stable CHF patients yields a small but significant increase in distance, primarily driven by patients with better baseline performance, suggesting repeat testing may not be necessary for those with poor baseline capacity.
