The pulmonary venous hypertension is one of the types of hypertension that is not so common. It is a consequence of a left heart dysfunction.
The condition is a problem commonly related to the paroxysmal nocturnal dyspnea or orthopnea, however, not an ordinary happening in the case of pulmonary arterial hypertension.
The relation with pulmonary hypertension
As indicated by WHO
group II classification, the most frequent initiating element for
causing pulmonary hypertension is pulmonary (venous) hypertension. The
leading factor is because of the fact that pulmonary venous
hypertension is integrally related with diastolic or systolic breakdown
happening at the left ventricle. It could also develop as consequence
of a valve failure similar to mitral stenosis, aortic regurgitation,
mitral regurgitation or aortic stenosis.
Most common manifestations
This type of hypertension can appear in different forms, the most frequent ways of it to appear are pleural effusions and pulmonary edema. Because when the heart is harmed it is very difficult for it to pump the blood in the rightful way, it directs a distinct pattern in the circulation process, which normally contributes to develop abnormally high pressure in the pulmonary veins. Since the pressure in the veins increases, it bounces back to the pulmonary arteries.
As described in WHO group II classification, the origin and development of this illness is quite different from the pulmonary arterial hypertension. The circulation of the blood through the lungs never gets interrupted. Rather, sending blood by the left heart affected in a dangerous way, which contributes to the abnormal blood flow that occurs in the lungs. This makes the patient to be in a potential danger for developing pleural effusions and pulmonary edema.
While both of these diseases are complications of the pulmonary hypertension, one of them is quite unusual while the other one is getting very common. The later one has a strong linkage with congestive heart failure, and a lot of research has described pulmonary venous hypertension as one of the major factors that participate in the development of congestive heart failure. As estimated in different medical journals, over 50 to 55 million Americans are suffering from pulmonary hypertension.
Some possible treatments
Since there is a strong relationship between pulmonary venous high blood pressure and congestive heart failure, the goal of the treatment is to enhance the function of the left ventricles by using beta blockers, diuretics, etc. In addition, measures can be taken by repairing or replacing the aortic valve or mitral valve. And a great amount of helpful measures have been lately introduced for successfully treating the illness.
