Pulmonary Hypertension (PH) is high blood pressure in the blood vessels of the lungs. It occurs when the small blood vessels that go through the lungs become thicker, constrict tighter or become plugged. This, in turn, leads to increased pressure in those vessels making the right side of the heart work harder to pump blood through the lungs. If high pressure remains, the heart will become enlarged and weaker, pumping blood less efficiently into the lungs and eventually throughout the body. Patients develop progressive fatigue and shortness of breath, two typical symptoms of PH.
Given the complexity of some of the drugs and how they are given, it is very important that physicians who can diagnose and treat PH with the full range of treatment options evaluate patients at a pulmonary hypertension center.
Early in the disease, symptoms may be nonspecific and can mimic symptoms of other medical conditions. It is also possible that patients may experience only limited symptoms.
The following are some of the most common symptoms of PH:
While we do not yet know the causes of PH, we do know that it affects people of all ages, races and ethnic backgrounds. The World Health Organization has classified five categories of PH based on either common changes in patient's blood vessels and heart function or associated diseases. Patients with connective tissue disease, liver disease, HIV disease are at risk for PH. Likewise, patients with valvular or hypertensive heart disease, or severe lung disease can also develop different forms of PH. We have an active research program at the Brigham and Women's Hospital looking into the potential causes of PH.
At the Brigham and Women's Hospital a team of clinicians who collaborate to treat each patient's pulmonary hypertension and associated medical conditions cares for patients. We are experienced in treating all forms of pulmonary hypertension. Numerous treatment options for pulmonary hypertension are available, depending on the type of pulmonary hypertension.
Treatment for PH can lower patients' pulmonary pressure, reduce symptoms, increase exercise capacity, and prolong life expectancy. Treatments for pulmonary arterial hypertension range from medications to transplant surgery. Our researchers are also studying new treatments for PAH all the time.
Several types of medications are used to treat PAH.
Many drugs for treating pulmonary hypertension have side effects. The dosage level must be carefully set and monitored to avoid serious side effects or complications. We work with patients to find the most effective and safe doses.
Chronic thromboembolic pulmonary hypertension is a rare form of both pulmonary hypertension and blood clots that go to the lung. Our pulmonary vascular team has experience in diagnosing and in both the medical and surgical treatment of this condition. Some, but not all, patients have a history of blood clots to the lung. Correct diagnosis is important because in many cases a surgical procedure called pulmonary thromboendarterectomy can successfully treat this condition. This procedure may be recommended for people whose secondary pulmonary hypertension is due to persistent pulmonary emboli (blood clots).
We not only diagnose and treat pulmonary hypertension, we also provide long-term care and support to help patients manage their condition. Our team of physicians and nurses develop individualized treatment plans and follow up with each patient on a regular schedule. Clinicians are available to answer patients' questions as needed. Patients also can access information about research opportunities and continuing education. Close follow-up care helps physicians detect early changes that may require further treatment.
