Stent decisions for kidney artery narrowing in hard-to-control blood pressure
Treatments studied
Part of Heart & circulation, Kidney & urinary clinical trials.
This trial studies whether using a pressure-based test called fractional flow reserve (FFR) helps doctors choose the right kidney artery stent for people with narrowing of kidney arteries and high blood pressure. It may help improve blood pressure control while avoiding unnecessary procedures.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Your blood pressure stays high even though you take at least two types of blood pressure medicines (top number ≥140 and/or bottom number ≥90)
- You have kidney artery narrowing seen on kidney artery angiography (a special X-ray test using contrast dye)
- The angiography shows at least one main kidney artery narrowing between 50% and 90%, with the artery diameter between 4.0 and 8.0 mm
- Your current blood pressure is not extremely high (top <200 and bottom <120) at the study day/randomization
- You can follow the study plan and sign the consent form
- You do not have certain conditions that would block participation (for example: specific non-atherosclerotic causes, recent heart attack/stroke/surgery, pregnancy, or contrast/aspirin/clopidogrel allergy)

Other trials that look related to this one.
This trial compares placing a tiny mesh tube (stent) to open the narrowed kidney artery versus continuing blood pressure medicines alone. It is for people whose high blood pressure is hard to control even with multiple medications and who have a blockage in the kidney artery that can be treated.
This trial tests whether placing a stent in a narrowed kidney artery—guided by a special pressure measurement (FFR)—can help control blood pressure better than medication alone. It is for people with difficult-to-treat hypertension caused by atherosclerosis (hardening of the arteries).
This trial studies whether placing a small stent in a severely narrowed kidney artery can improve outcomes for people with high-risk, artery-hardening kidney blood-flow problems. It focuses on people whose high blood pressure or kidney function has been getting worse despite multiple medications.
This trial tests a new device that uses ultrasound to treat nerves in the kidney arteries that may be overactive and raising your blood pressure. It's for people whose blood pressure stays high despite taking at least two medications.
This trial tests a new way to decide if opening a narrowed kidney artery will help lower high blood pressure. It uses a special wire to measure pressure inside the artery before treatment.
This study tests a drug-coated balloon used during a kidney-artery procedure for people with non-atherosclerotic (non–plaque-related) narrowing. It may help improve blood flow to the kidney and better control blood pressure, while also checking safety.
