Baseline and Follow-Up 6-Min Walk Distance and Brain Natriuretic Peptide Predict 2-Year Mortality in Pulmonary Arterial Hypertension

Study Questions:

What is the individual and additive ability of pretreatment and post-treatment 6-minute walk distance (6MWD) and B-type natriuretic peptide (BNP) to discriminate 2-year survival in patients with pulmonary arterial hypertension (PAH)?
