Chest Pain, Sickle Cell Anemia
Effects of Nitric Oxide and Nitroglycerin in Patients With Sickle Cell Anemia
Sickle cell anemia is the most common genetic disease affecting African-Americans. About 1 in every 1000 African-Americans has the disease and 1 in every 12 carry the genes that could be passed on to their children.
