A person with pulmonary hypertension has abnormally high blood pressure in the arteries that deliver blood from the heart to the lungs. There are two main forms of pulmonary hypertension. In someone with primary pulmonary hypertension, there is no clear cause for the high blood pressure. In someone with secondary pulmonary hypertension, the high blood pressure is caused by underlying heart or lung disease. Pulmonary hypertension places abnormal stress on the heart, which can lead to congestive heart failure. Only about 1 out of 500,000 people in the US develop pulmonary hypertension each year.
