Study typeTreatment
Scientific titleThe role of angioplasty after selecting patients according to the doppler resistive index: a randomised controlled trial
Study objectivesMedical treatment and renal angioplasty in renovascular hypertension
Ethics approval(s)Comite d'ethique de la recherche, Hopital Notre Dame, Centre Hospitalier de L'universite de Montreal (CHUM), Montreal, Québec approved on 14th May 2002.
Health condition(s) or problem(s) studiedRenovascular hypertension
InterventionAdded 25/02/2009: the study was terminated early due to recruitment issue.

Inclusion of patients presenting a controlled hypertension with 2 or 3 antihypertensive drugs and risk factors for renovascular hypertension. Selection on Doppler inclusion criteria (Resistive index less than 0.75) and renal angiography renal artery stenosis of more than 60% in diameter.

Group 1: Medical treatment (duration: 12 months)
Group 2: Renal angioplasty

Follow up for one year following angioplasty.

Trial details received: 12 Sept 2005
Intervention typeOther
Primary outcome measureSystolic and diastolic blood pressure 12 months post-randomisation
Secondary outcome measures1. Blood pressure at 1 and 6 months post-randomisation
2. Clinical success on blood pressure control at 12 months
3. Serum creatine clearance when off antihypertensive drugs during 12 months? Does it mean that you have no control over those?
4. Morbidity related to cardiovascular events during follow-up
5. Incidence of renal artery restenosis
