Primary Pulmonary Hypertension
PPH causes some of the cell lining of the lung's blood vessels to weaken and allow leakage. The leaking of blood out of the vessels causes the muscles that surround the blood vessels to constrict. This continuous constriction increases the pressure within the blood vessels. Gradually over time, this chokes off the flow of blood between the heart and lungs. The cutoff of blood will cause causing dizziness, exhaustion, fainting and may lead to heart failure. Effective treatment can allow a PPH victim to survive more than 10 years after diagnosis.
What causes Primary Pulmonary Hypertension?
Scientists do not know what exactly causes Primary Pulmonary Hypertension. Some researchers believe the blood vessels are particularly sensitive to certain internal or external factors, and constrict, or narrow, when exposed to these factors. There may be a genetic factor, an immune system factor, or sensitivity to drugs or other chemicals.
Diet drugs present a possible cause
Recently, an association between some PPH cases and the serotonin-effecting appetite suppressants fenfluramine (Pondimin) and dexfenfluramine (Redux) has been established. A long term study in Europe showed that out of 95 cases, 30 had taked one of these appetite suppressants: dexfenfluramine (Redux), fenfluramine (Pondimin), diethylpropion (Tenuate), clobenzorex, fenproporex, or phenmetrazine. Of the 30 cases, 18 had used them more than three months.

A method of detecting PPH is using a catheter. A hollow, flexible
tube for insertion into a body cavity, duct, or vessel. The tube
extends into the heart to measure blood pressure. Unlike the
echnocardiogram, which is harmless and not risky, there is some
risk associated with the catheterization. Exercising may have
the effect of increasing the ability of a cardiac catheter to
