What Is Pulmonary Hypertension?


What is pulmonary hypertension?


Pulmonary hypertension is a condition in which the high blood pressure damages the arteries in the lungs and the right side of the heart. The large arteries in the lungs are pulmonary trunk, and the tiny ones are called pulmonary arterioles.

In some cases, arterioles become narrowed, blocked or destroyed, which makes the blood flow through the lungs harder. Therefore, the blood pressure in the arteries in the lungs are raised. The right ventricle, the lower right chamber of the heart, has to work harder to pump blood through the lungs. Over time, the heart begins to weaken and finally fails.

Not all cases are serious and fatal, but some of them are curable. Proper and prompt treatments are needed to lessen the symptoms and improve the quality of life.
