When high blood pressure affects the lungs

Pulmonary hypertension—a serious illness that affects the lungs and heart—has many possible causes, including a range of diseases and underlying conditions, as well genetic mutations and exposure to certain drugs. It is challenging to diagnose and treat, but a novel experimental drug that targets one form of the disease appears promising. The drug, called sotatercept, targets one of the dysregulated pathways that causes pulmonary arterial hypertension—one specific form of the disease.
