Pathways in pulmonary arterial hypertension: the future is here.

ABSTRACT: It is well established that the endothelin, nitric oxide and prostacyclin pathways play an important role in the development of pulmonary arterial hypertension (PAH). Indeed, the therapeutic options currently available for the management of PAH all act on one of these mechanistic pathways. However, this is an exciting time for both clinicians and scientists, as increased understanding of the mechanisms involved in the pathogenesis and progression of PAH has resulted in the development of a number of novel therapeutic options. This article highlights how the introduction of new compounds such as macitentan, riociguat and selexipag, which act on the endothelin, nitric oxide and prostacyclin pathways, respectively, have the potential to further improve the prognosis for patients with PAH.

Project description:Treatment patterns of pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) in Finland are unknown. Guidelines now recommend early escalation of treatment for PAH. We evaluated how well Finnish practice follows guidelines, and how treatment initiations and outcomes are related. The pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension patients in Finland cohort includes all PAH and CTEPH patients diagnosed between 2008 and 2020 in all Finnish university hospitals. Drug therapy was analysed in patients with medical/procedural history available, and changes in the 4-tier comparative, prospective registry of newly initiated therapies for pulmonary hypertension (COMPERA) 2.0 risk score were evaluated. PAH patients (n = 268) were initially treated with monotherapy (52%) or double therapy (24%). After year 2015, double therapy use increased to 39%. PAH treatment at 1 year after diagnosis included phosphodiesterase 5 inhibitors (71%), endothelin-receptor antagonist (48%), prostacyclin analogue (7%), calcium channel blocker (12%) and selexipag (1%). 35% achieved low risk at 1 year, increasing to 44% for patients diagnosed after 2015. Those remaining at intermediate-high (IH) or high risk (H) (28%) were not treated less aggressively than others but were older, had more comorbidities, and often history of smoking. CTEPH patients (n = 189) were treated with pulmonary endarterectomy (PEA) (27%), balloon pulmonary angioplasty (BPA) (11%) and medical therapy only (41%) within 1 year from diagnosis. 45% achieved low risk at 1 year. We present additional results on treatment of IH and H patients, patient characteristics preceding death, and treatment persistence. We found less treatment of PAH patients with double or triple therapies and of CTEPH patients with PEA and BPA than expected but with good results. Patients not reaching low or intermediate COMPERA 2.0 were old and had comorbidities.
