Background

In pulmonary arterial hypertension PAH, the six-minute walk test 6MWT is believed to be representative of patient-s daily life physical activities DLPA. Whether DLPA are decreased in PAH and whether the 6MWT is representative of patient-s DLPA remain unknown.

Methods

15 patients with idiopathic PAH IPAH and 10 patients with PAH associated with limited systemic sclerosis PAH-SSc were matched with 15 healthy control subjects and 10 patients with limited systemic sclerosis without PAH. Each subject completed a 6MWT. The mean number of daily steps and the mean energy expenditure and duration of physical activities >3 METs were assessed with a physical activity monitor for seven consecutive days and used as markers of DLPA.

Results

The mean number of daily steps and the mean daily energy expenditure and duration of physical activities >3 METs were all reduced in PAH patients compared to their controls all p<0.05. The mean number of daily steps correlated with the 6MWT distance for both IPAH and PAH-SSc patients r = 0.76, p<0.01 and r = 0.85, p<0.01, respectively.

Conclusion

DLPA are decreased in PAH and correlate with the 6MWT distance. Functional exercise capacity may thus be a useful surrogate of DLPA in PAH.
