Pulmonary hypertension, also called PH, is a life-threatening condition that occurs when a patient has high blood pressure in the arteries leading to the lungs and the right side of the heart.
Unlike regular hypertension or high blood pressure, pulmonary hypertension occurs when the arteries in the lungs become blocked or narrow, making it harder for the heart to pump blood through them. This situation raises blood pressure in the lungs and causes the heart to weaken, which may eventually lead to heart failure.
Shortness of breath, dizziness, and chest pressure are symptoms. While the condition worsens over time, medications and oxygen therapy can help lessen symptoms and improve quality of life.
