Pulmonary Hypertension (PH) is a chronic disease that causes significant structural deterioration in the right atrium and ventricle. In the past 1–2 decades, life expectancy in patients with PH has increased due to improved awareness, diagnosis and advancements in treatment.
Patients with pulmonary arterial hypertension (PAH) experience long diagnostic delays, high functional class at diagnosis and poor prognosis. We aimed to study the differentiative and predictive value of 90 inflammatory and immunomodulatory related proteins in idiopathic and hereditary PAH (IPAH/HPAH) and systemic sclerosis-associated PAH (SSc-APAH).
