Pulmonary Arterial Hypertension

Pulmonary arterial hypertension (PAH) is a condition characterized
by high blood pressure in the arteries that carry blood from the heart to
the lungs. This occurs when the small arteries in the lungs become
narrowed or blocked, leading to increased pressure and making the
heart work harder to pump blood through the lungs. Common symptoms
include shortness of breath, fatigue, and chest pain, and it can be
caused by various factors, including heart disease and lung disease.
Diagnosis typically involves a series of tests, and treatment options may
include medications and lifestyle changes.
