The Study of Novel Dual Renin Angiotensin Aldosterone System (RAAS) Blockade; Valsartan/Aliskiren in African American Patients With Hypertension and the Metabolic Syndrome

• Status: Withdrawn
• Trial end date: 2012-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Study purpose: African Americans with hypertension and markers of metabolic syndrome (small elevations in blood glucose, triglycerides and or weight) are at a high risk of cardiovascular (heart and blood vessel) problems. There is a circulating factor called angiotensin II that increases risk and may be more important in African Americans who have up to 20 times greater risk of losing kidney function and requiring dialysis. Research Investigators, including those at the University of Michigan, found one drug (Ramipril) that blocks angiotensin II effects significantly and improves kidney function in African Americans.

The purpose of The SAAVE Study is to determine whether the combination of two new blockers (Valsartan and Aliskiren) of angiotensin II, are better able to lower blood pressure, also improve some of the risk factors for cardiovascular problems and provide greater protection to the heart and kidneys.
