Secondary Pulmonary Hypertension in Adults With Sickle Cell Anemia

Sponsor: National Heart, Lung, and Blood Institute (NHLBI)

Summary

The purpose of this study is to determine how often people with sickle cell anemia develop pulmonary hypertension a serious disease in which blood pressure in the artery to the lungs is elevated. Men and women 18 years of age and older with sickle cell anemia may be eligible for this study. Participants will undergo an evaluation at Howard University s Comprehensive Sickle Cell Center in Washington, D.C. or at the National Institutes of Health in Bethesda, Maryland. It will include the following: * medical history * physical examination * blood collection (no more than 50 ml., or about 1/3 cup) to confirm the diagnosis of sickle cell anemia, sickle cell trait or beta-thalassemia (Some blood will be stored for future research testing on sickle cell anemia.) * echocardiogram (ultrasound test of the heart) to check the pumping action of the heart and the rate at which blood travels through the tricuspid valve. Following this evaluation, a study nurse will contact participants twice a month for 2 months and then once every 3 months for the next 3 years for a telephone interview. The interview will include questions about general health and recent health-related events, such as hospitalizations or emergency room visits. ...
