Blood Pressure Lowered By Kidney Stenting In Patients With Severe Hypertension

Patients with uncontrolled renovascular hypertension saw a significant improvement in their blood pressure with renal artery stent deployment. The multicenter HERCULES trial, evaluating the safety and effectiveness of the RX Herculink Elite Stent, found that patients with higher blood pressure levels at baseline had the most dramatic reduction in blood pressure following intervention. Trial details appear inCatheterization and Cardiovascular Interventions, a journal published by Wiley on behalf of the Society for Cardiovascular Angiography and Interventions (SCAI). 


Narrowing of the arteries to the kidney - known as renal artery stenosis (RAS) - is mainly caused by the build-up of fat and cholesterol (atherosclerosis) along the artery walls. The plaque build-up can cause high blood pressure and kidney damage. While kidney artery stenting is considered a safe procedure, the efficacy of the procedure for lowering blood pressure and preventing injury that leads to end-stage renal disease remains unclear, particularly when compared to medicines alone.
