Abstract
This study aimed to identify the long-term clinical outcomes and prognostic factors of patients with systemic lupus erythematosus (SLE)-associated pulmonary arterial hypertension (PAH) confirmed by right heart catheterisation.A multicentre prospective cohort of SLE-associated PAH was established. Baseline and follow-up records were collected. The primary end-point was death. The secondary exploratory end-point was treatment goal achievement (TGA), defined as an integrated outcome.In total, 310 patients were enrolled from 14 PAH centres. The 1-, 3- and 5-year survival rates were 92.1%, 84.8% and 72.9%, respectively. The 1-, 3- and 5-year TGA rates were 31.5%, 53.6% and 62.7%, respectively. Baseline serositis, 6-min walking distance >380 m and cardiac index ≥2.5 L·min-1·m-2 were identified as independent prognostic factors of TGA. Patients with baseline serositis were more likely to reach TGA after intensive immunosuppressive therapy. TGA was identified as a positive predictor of survival in patients with SLE-associated PAH.TGA was associated with long-term survival, which supports the treat-to-target strategy in SLE-associated PAH. Baseline heart function predicted both survival and treatment goal achievement in patients with SLE-associated PAH. Patients with serositis at baseline tended to benefit from intensive immunosuppressive therapy and have a better clinical outcome.
