Connective Tissue Disease–associated Pulmonary Arterial Hypertension in the Modern Treatment Era

Survival of patients with SSc-PAH in the modern treatment era is better than in historical series. A significant proportion of patients with mild functional impairment or exercise-induced SSc-PAH have evidence of disease progression. Survival of patients with respiratory disease-associated pulmonary hypertension is inferior. SLE-PAH has a better prognosis than SSc-PAH.
