Key result
A 6MWT does not significantly change diastolic blood pressure or oxygen saturation in heart failure.
Why the study?
Does walking for 6 minutes significantly change diastolic blood pressure and oxygen saturation in older adults with heart failure?
Population
20 older adults with heart failure in an outpatient cardiology clinic

6MWT appears safe without DBP or SpO2 shifts in older HF adults; leaves open whether SpO2 predicts functional status in prospective studies.

Does walking for 6 minutes significantly change diastolic blood pressure and oxygen saturation in older adults with heart failure?
A 6-minute walk test does not significantly change diastolic blood pressure or oxygen saturation in older adults with heart failure, though oxygen saturation correlates with functional status.
Schwarz et al. (2003) conducted a cross-sectional in Heart failure (n=20). 6-minute walk test was evaluated on Diastolic blood pressure and oxygen saturation. In adults with heart failure, diastolic blood pressure and oxygen saturation did not significantly differ after a 6-minute walk test, though functional status was related to oxygen saturation.
