Borderline Pulmonary Arterial Pressure Is Associated with Decreased Exercise Capacity in Scleroderma

Abstract

MPAP and resistance in the upper normal range at rest and moderate exercise are associated with decreased exercise capacity and may indicate early pulmonary vasculopathy in patients with systemic sclerosis. Investigations on the prognostic and therapeutic implications of such borderline findings are warranted. Clinical trial registered with http://www.clinicaltrials.gov (NCT00609349).
