Efficacy and tolerability of triple sequential combination therapies with selexipag in patients with pulmonary arterial hypertension: insights from a single-centre study
Abstract
In this single-centre study we aimed to evaluate the efficacy and tolerability of prostacyclin receptor agonist selexipag in patients with pulmonary arterial hypertension (PAH).
The study included 110 out of the 1071 patients enrolled in the Evaluation of Pulmonary Hypertension Risk factors Associated with Survival study (EUPHRATES) and treated with selexipag added on background dual PAH therapies. The ESC/ERS 2022, SPAHR, French Registry, COMPERA 2.0 and REVEAL lite 2 models were used for risk predictions.
Age (mean+SD) was 43.4+16.5 years and 84.5 % of patients were female. The PAH was idiopatic, and was associated with congenital heart disease (CHD), connective tissue disease (CTD) and drug in 47.2 %, 46.4 %, 5.5 % and 1 %, respectively. Background dual therapies, functional class (FC) was II, III and IV in 20 %, 65 %, and 15 % of patients. Six-minute walk distance (6MWD) was 314 + 134 m and serum N-terminal-pro-brain natriuretic peptide (NT-proBNP) level was 882+1732 ng/l. Tricuspid annular planary excursion (TAPSE) and tissue velocity (St), right atrial area and pulmonary arterial diameter were 2.02+0.48 cm,12.4+2.8 cm/sec,21.4+7.2 cm2 and 3.54+0.77 cm, respectively. Invasively evaluated pulmonary arterial mean pressure was 60.2±19.9 mm Hg, and pulmonary vascular resistance was 12.3±10.8 Wood units. COMPERA 2.0 1st, 2nd, 3rd and 4th risk strata were noted in 15.5 %, 31.8 %, 2.7 % and 10 %, and French Registry strata 0,1,2 and 3 were documented in 70 %, 14.5 %, 11 %, and…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 1,071 participants or records.
