An Overview of Pulmonary Hypertension

The blood vessels in human beings distribute blood to the left and right part of the heart. The distribution of the blood from the right wing of the heart to the whole body is called systemic circulation. The circulation of blood to the lung from the right side of the heart is known as pulmonary circulation. Pulmonary hypertension occurs when there is the constriction of blood vessels supplying blood to the lungs. As a result, blood supply to the lung decreases, thus making it tough for the heart to pump blood to the other parts of the body.

It creates stress on the heart and formation of fluid in the liver and other tissues. In this condition, patients might experience short breathing and dizziness.

Causes behind the occurence of Pulmonary Hypertension
There may be different causes of pulmonary hypertension. Chronic pulmonary disease, embolism, malfunctioning of the left ventricle and some other underlying diseases may result in to pulmonary hypertension.

Low oxygen level in the blood may also cause hypertension in the pulmonary arteries.

Diagnosing Pulmonary Hypertension
There are some tests that could help you evaluate the condition of pulmonary hypertension. Ct scanning, X-ray and echocardiogram are perfect tests to diagnose pulmonary hypertension. Angiography is also very helpful in this connection.

Treatment
Although there is no direct treatment for pulmonary hypertension, the treatment of underlying diseases may help dilate the blood vessels. Some other treatments include diuretics, blood thinning medicines, supplemental oxygen and calcium blockers.

Over the counter medications like Bosentan, Traceler, and Prostacyclin are also helpful in dilating the arteries although there is no hundred percent cure for this disease. Recently Sildenafil has also found to be useful in lowering the pressure in pulmonary arteries.
