Purpose
The RAVE study will compare renal revascularization to medical management for people with atherosclerotic renal vascular disease (ARVD) and the indication for revascularization.
| Condition | Intervention |
|---|---|
|
Hypertension, Renovascular |
Procedure: Angiographic renal revascularization |
| Study Type: | Interventional |
| Study Design: | Allocation: Randomized Endpoint Classification: Efficacy Study Intervention Model: Parallel Assignment Masking: Open Label Primary Purpose: Treatment |
- Dialysis
- Death
- Doubling of creatinine
| Estimated Enrollment: | 240 |
| Study Start Date: | January 2005 |
| Estimated Study Completion Date: | December 2006 |
It is uncertain whether patients with renal vascular disease will have renal or mortality benefits from re-establishing renal blood flow with renal revascularization procedures. Patients will be assessed for the standard nephrology research outcomes of progression to doubling of creatinine, need for dialysis, and death, as well as other cardiovascular outcomes. The investigators will also establish whether the use of a new inexpensive, simple and available ultrasound test, the renal resistance index (RRI), can identify patients with renal vascular disease who will not benefit from renal revascularization procedures.
