Behind the Science: Central, Hematological and Peripheral Effects of Sotatercept | JACC

In this episode of Behind the Science, Dr. Yogesh Reddy joins to explore how sotatercept improves outcomes in pulmonary arterial hypertension (PAH) and why its effects go beyond traditional vasodilation. Using detailed invasive hemodynamic testing, exercise protocols, and skeletal muscle assessment, the study highlights key mechanisms, including reductions in pulmonary vascular resistance, improved right ventricular efficiency, increased hemoglobin, and enhanced oxygen extraction at the muscle level. These findings provide new insight into sotatercept's multi-system effects and help explain the significant improvements in exercise capacity seen in clinical trials—offering important implications for future PAH therapies. #Cardiology #PulmonaryHypertension #PAH #Sotatercept #ACC #JACC #MedicalResearch #HeartHealth
