Using remote ischemic preconditioning to prevent kidney injury during coronary angiograms

Effectiveness of Remote Ischemic Preconditioning for Prevention of Contrast Induced Acute Kidney Injury in Patients Undergoing Coronary Angiograms.

Not applicable Interventional The University of Texas Medical Branch, Galveston · NCT05147831

This study is testing if a simple treatment called remote ischemic preconditioning can help protect the kidneys from injury during coronary angiograms in patients who are at risk.

What this trial studies

This study investigates the effectiveness of remote ischemic preconditioning (RIPC) as a preventive measure against contrast-induced acute kidney injury (CI-AKI) in patients undergoing coronary angiograms. CI-AKI is a significant risk associated with the use of contrast media during imaging procedures, leading to serious health complications. The study aims to determine if RIPC can reduce the rise in creatinine levels and the incidence of renal replacement therapy in moderate to high-risk patients. By employing a non-invasive and low-cost approach, the research seeks to establish a safe method to mitigate the risks of CI-AKI.

Who should consider this trial

Good fit: Ideal candidates include patients with renal clearance below 60 ml/min who are undergoing interventional or diagnostic procedures involving contrast media.

Not a fit: Patients on dialysis, those under 18 years old, or those with certain medical conditions that prevent RIPC will not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly reduce the incidence of kidney injury in patients undergoing coronary angiograms.

How similar studies have performed: While the concept of remote ischemic preconditioning is promising, further randomized controlled trials are needed to confirm its effectiveness in preventing CI-AKI.
