Multicenter Study Comparative Study Clinical TrialCreation of a model comparing 6-minute walk test to metabolic equivalent in evaluating treatment effects in pulmonary arterial hypertension.
The 6-minute walk test (6MWT) is the current standard to assess exercise capacity in pulmonary arterial hypertension (PAH). We compared the Naughton-Balke treadmill test reported in exercise metabolic equivalents (METs) with the 6MWT to evaluate whether MET could be a useful tool to assess exercise capacity. ⋯ MET appears to be a reliable measure of exercise capacity in PAH, and correlates with 6MWT. MET can be used in clinical assessment and is helpful in demonstrating improvements in exercise capacity in less sick patients.
