What this Trial Is About

African American adults in the United States have the highest prevalence rate of high blood pressure (hypertension) and heart failure in the world.

This trial will test if administration of the xanthine oxidase inhibitor - Allopurinol (commonly used in the treatment of gout), given over a period of 8 weeks, will improve heart function, exercise ability and quality of life in African American Veterans with resistant hypertension.
