Understanding Pulmonary Arterial Hypertension (PAH)

Before delving into the specifics of Sotatercept, it’s crucial to grasp the fundamentals of Pulmonary Arterial Hypertension (PAH), a condition that significantly impacts the lives of those it affects. PAH is a type of high blood pressure that targets the arteries in the lungs and the right side of the heart, leading to symptoms such as shortness of breath, dizziness, and fatigue. Over time, these symptoms can escalate, severely limiting physical activity and diminishing the quality of life.

The progression of PAH involves the narrowing or blockage of pulmonary arteries, which increases the resistance against the heart, forcing it to work harder to pump blood through the lungs. This added strain can eventually weaken the heart, leading to heart failure, a serious complication of untreated PAH.

Given the severity of PAH and its impact on heart function, finding effective treatments is paramount. This is where Sotatercept enters the scene, offering a new avenue for therapy by directly targeting the mechanisms underlying the disease, beyond merely addressing the symptoms.
