Treatment of pulmonary hypertension after seven world symposia

This review focuses on the advancements in the treatment of pulmonary hypertension (PH), especially after the Food and Drug Administration (FDA) approval of sotatercept and the advances in treatment recommendations after seven World Symposia on PH. PH, a complex and progressive condition defined hemodynamically by a mean pulmonary artery pressure >20 mmHg, encompasses multiple PH groups, each with distinct pathophysiological characteristics and treatment implications. Diagnosing PH can be challenging because symptoms like shortness of breath, fatigue, and chest pain are nonspecific. Contemporary treatment of pulmonary arterial hypertension aims to improve outcomes, symptoms, and overall quality of life, with a primary focus on preventing and treating right ventricular failure. Comprehensive risk stratification remains crucial, aiding in personalized therapy adjustments that improve patients’ outcomes. This review also touches upon the limited treatment options for other PH groups, like PH associated with left heart disease, parenchymal lung diseases, and chronic thromboembolic PH, underscoring the need for expanded therapeutic options. Despite advances, challenges remain: diagnostic delays, misdiagnosis, absence of head-to-head clinical trials, and the timing of introducing newer treatments such as sotatercept are discussed, emphasizing an integrated approach that transcends vasodilation to target underlying disease mechanisms. Future directions envision a comprehensive risk stratification incorporating right ventricular function and a mechanism-based treatment paradigm, encouraging a tailored therapeutic approach in PH management.
