Abstract

Prevalence of moderate to severe PH was similar in SSc patients with and those without ILD. In patients with ILD, a lower PaO2 was the unique independent indicator associated with PH. In some patients with severe ILD, PH was out of proportion to the degree of fibrosis. A linear correlation between DLCO and systolic pulmonary arterial pressure was observed only in patients without ILD. All these indicators should assist identification of patients with or without ILD requiring diagnostic procedures for PH before annual screening.
