Key result
Pedometer scores of customary activity correlated with quality of life (r=0.47, P=0.04) and limb blood flow, whereas maximal treadmill and corridor walk tests did not.
Why the study?
Do different tests of exercise capacity correlate with quality of life and hemodynamics in patients with stable symptomatic heart failure?
Population
36 patients with mild-moderate chronic heart failure

Pedometer activity associated with QoL and hemodynamics unlike lab tests; hypothesis-generating and should not yet change practice in HF.

Do different tests of exercise capacity correlate with quality of life and hemodynamics in patients with stable symptomatic heart failure?
Effect estimate: r(S) 0.47
p-value: p=0.04
Pedometer-assessed customary activity may better reflect quality of life and hemodynamics in heart failure patients than traditional laboratory-based exercise tests.
Houghton et al. (2002) conducted a cross-sectional in mild-moderate chronic heart failure (n=36). Pedometer-assessed customary activity vs. Laboratory-based maximal treadmill and corridor walk tests was evaluated on Correlation between pedometer scores and quality of life questionnaire scores (r(S) 0.47, p=0.04). Pedometer scores of customary activity correlated with quality of life (r=0.47, P=0.04) and limb blood flow, whereas maximal treadmill and corridor walk tests did not.
