Summary

Contrast-induced nephropathy (CIN) is a common complication in high-risk patients undergoing percutaneous coronary intervention (PCI) due to exposure to iodinated contrast agents. CIN is associated with increased morbidity, prolonged hospital stays, and higher healthcare costs. Current preventive strategies include adequate hydration and minimizing contrast volume; however, there is no universally effective pharmacological intervention. Recent studies suggest that inorganic nitrates can enhance renal perfusion, reduce oxidative stress, and improve endothelial function, potentially lowering the risk of CIN. This study aims to evaluate the efficacy and safety of a beet-derived inorganic nitrate-based food product for the prevention of CIN in high-risk patients undergoing PCI. This is a randomized, controlled, open-label clinical trial comparing two groups: 1. Intervention Group: Patients receiving the beet-derived inorganic nitrate-based food product for 5 days (starting 24 hours before PCI). 2. Control Group: Patients receiving standard medical care without additional nitrate supplementation. We hypothesize that the nitrate-based food product will significantly reduce the incidence of CIN compared to standard care. Additionally, we expect: 1. A lower increase in kidney injury biomarkers (NGAL, cystatin C) in the intervention group. 2. A slower decline or even improvement in eGFR at follow-up. 3. A potential reduction in MACE due to the vasoprotective effects of nitrates. 4. Improved quality of life scores (EQ-5D) in the intervention group. If successful, this study will provide new evidence supporting the use of dietary nitrates for renal protection and may contribute to the development of novel, cost-effective prevention strategies for CIN.

Conditions

• Contrast-induced Nephropathy Following Percutaneous Intervention (CIN)

Interventions

Type	Name	Description
DIETARY_SUPPLEMENT	Beet-Derived Inorganic Nitrate-Based Food Product	This intervention consists of an orally administered food product enriched with inorganic nitrates derived from beetroot. Participants in the intervention group will consume a standardized dose of 12 mmol of nitrate per day for 5 days (starting 24 hours before PCI and continuing for 4 days post-procedure). The product is designed to enhance nitric oxide bioavailability, improve renal perfusion, reduce oxidative stress, and lower the risk of contrast-induced nephropathy (CIN).
