Millions of people are affected by high blood pressure (hypertension), a condition in which blood travels through the body's arteries at a pressure too high for good health. High blood pressure in the arteries that supply the lungs is called pulmonary hypertension (PHT). The blood pressure measured by cuff on your arm isn't directly related to the pressure in your lungs. The blood vessels that supply the lungs constrict and their walls thicken, so they can't carry as much blood. As in a kinked garden hose, pressure builds up and backs up. Although the terms primary pulmonary hypertension (meaning of unknown cause) and secondary pulmonary hypertension (meaning due to another medical condition) still persist in materials disseminated to patients and the general public, these terms have largely been abandoned in the medical literature. This change has occurred because the older dichotomous classification did not reflect pathophysiology or outcome.The heart works harder, trying to force the blood through. Nearly 50 million Americans have high blood pressure (also known as hypertension). It occurs when blood travels through the body's arteries at a pressure too high for good health.It is most commonly found in women between ages 20 and 40. However, men and women in all age ranges as well as very young children can develop PPH. There are two main kinds of pulmonary hypertension. One runs in families or appears for no known reason. The other kind is related to another condition, usually heart or lung disease. The most common cause of pulmonary hypertension is left heart failure leading to pulmonary venous hypertension (WHO Group II). This may be due to systolic or diastolic malfunction of the left ventricle or due to valvular dysfunction such as mitral regurgitation, mitral stenosis, aortic stenosis, or aortic regurgitation. It usually manifests as pulmonary edema or pleural effusions.Treatment is determined by whether the PH is arterial, venous, hypoxic, or miscellaneous.What are the signs of pulmonary hypertension?Common signs of pulmonary hypertension are getting short of breath with activity, feeling tired, fainting and having chest pain. Symptoms usually limit a person's ability to exercise and do other activities.What is the treatment?The first priority is to raise the oxygen level in the blood with oxygen therapy. Children who respond to pulmonary vasodilators, which are medications that relax the muscles in the blood vessel walls and cause the blood vessels to widen, are treated with calcium channel blockers. Calcium channel blockers help the heart to pump blood by relaxing the smooth muscle in the walls of the heart. Patients who dont respond to a vasodilator are treated with prostacyclin, which is another drug that dilates the blood vessels. The child may also be given additional medications to treat heart failure, if present. In secondary pulmonary hypertension, surgery may be necessary to correct any known cause. Patients who do not respond to any treatment may need a lung transplant.
