Effect of ACE/ARBs on Kidney Health During Heart Procedures

The Effect of Continuing or Discontinuing ACE-I/ARBs Therapy on the Incidence of Contrast-induced Nephropathy in Patients With Chronic Kidney Disease Undergoing Coronary Angiography; a Randomized Controlled Trial

NA · An-Najah National University · NCT05271448

What this trial studies

This research investigates whether continuing or withholding ACE inhibitors (ACE-I) or angiotensin receptor blockers (ARBs) affects the risk of contrast-induced nephropathy (CIN) in patients with chronic kidney disease undergoing coronary angiography. The study involves a randomized control trial design with two groups: one group continues their ACE-I/ARB therapy, while the other group has their therapy withheld 24 hours prior to the procedure. The aim is to provide evidence-based guidelines on the safety of these medications in this specific patient population.

Who should consider this trial

Good fit: Ideal candidates include patients with chronic kidney disease (GFR between 15 and 60 ml/min/1.73 m2) who have been on ACE-I or ARB therapy for at least one month and are scheduled for elective coronary angiography.

Not a fit: Patients with acute kidney failure, severe heart conditions, or those who have recently undergone similar procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for patients with chronic kidney disease undergoing heart procedures, potentially reducing the incidence of contrast-induced nephropathy.

How similar studies have performed: Previous studies have shown conflicting results regarding the use of ACE-I/ARBs in this context, making this research both relevant and necessary to clarify their role.
