Spironolactone for Pulmonary Arterial Hypertension

Background: \- High blood pressure in the lungs, known as pulmonary arterial hypertension (PAH), is a rare disorder. In spite of recent advances in treatment, the death rate remains unacceptably high. Lung blood vessel function can be harmed by progressive injuries, such as inflammation, leading to worsening of the disease. A drug called spironolactone has been known to improve blood vessel function and reduce inflammation. Some people with PAH take spironolactone to help treat fluid retention. However, its effect on inflammation and blood vessel function in patients with PAH is not known. Researchers want to see if spironolactone can help these conditions in people with PAH. Objectives: \- To test the effectiveness of spironolactone in treating pulmonary arterial hypertension. Eligibility: \- Individuals at least 18 years of age with pulmonary arterial hypertension. Design: * This study will last for 24 weeks. Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. * Participants will take either spironolactone or a placebo. They will take their study drug or placebo for 7 weeks. Treatment will be monitored with regular blood tests. * In Week 8, participants who have had no reaction to the treatment will receive a higher dose of the drug or placebo. * In Week 12, participants will have a study visit with heart and lung function tests. They will also have a 6-minute walk test, and provide blood and urine sample…
