What are causes of pulmonary hypertension?

Some common underlying causes of pulmonary hypertension include high blood pressure in the lungs’ arteries due to some types of congenital heart disease, connective tissue disease, coronary artery disease, high blood pressure, liver disease (cirrhosis), blood clots to the lungs, and chronic lung diseases like emphysema …

What is considered severe pulmonary hypertension?

The pulmonary arterial pressure was measured using the echocardiography. A value greater than or equal to 35 mm Hg is considered PAH and classified as follows: mild PAH (35–50 mm Hg), moderate PAH (50–70 mm Hg), and severe pulmonary hypertension (> 70 mm Hg) [15].

What is pulmonary hypertension due to left heart disease?

Abstract. Pulmonary hypertension (PH) due to left heart disease (LHD) is the most common type of PH and is defined as mean pulmonary artery systolic pressure of >20 mm Hg and pulmonary capillary wedge pressure >15 mm Hg during right heart catheterization.

Why does pulmonary hypertension affect the right ventricle?

As a result, the heart walls thicken and the right ventricle expands to increase the amount of blood it can hold. But these changes create more strain on the heart, and eventually the right ventricle fails. Blood clots. Having pulmonary hypertension increases the risk of blood clots in the small arteries in the lungs.

What is the best treatment for pulmonary hypertension?

Oxygen therapy. Breathing pure oxygen is sometimes recommended as a treatment for pulmonary hypertension, especially for those who live at a high altitude or have sleep apnea. Continuous oxygen therapy may be needed.
