Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults diagnosed with non-ST elevation acute coronary syndrome who are at moderate to high risk for contrast-induced nephropathy.

Probably not a fit

Patients with persistent ST segment elevation acute coronary syndrome or those on dialysis may not benefit from this study.

What this trial studies

This study aims to evaluate the effectiveness of beetroot juice supplementation in preventing contrast-induced nephropathy in patients hospitalized for non-ST elevation acute coronary syndrome who are at high risk for kidney injury. Participants will be divided into two groups: one receiving beetroot juice along with standard care, and the other receiving standard care alone. The intervention involves consuming 500 mL of beetroot juice daily for seven days or until discharge, while both groups will receive additional therapies to prevent kidney damage if needed. The study seeks to determine if the inorganic nitrates in beetroot juice can protect kidney function during cardiac catheterizations.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of kidney damage in patients undergoing heart procedures.

How similar studies have gone: Previous studies have shown promising results with inorganic nitrates in preventing contrast-induced nephropathy, but this specific approach using beetroot juice is novel.
