Flozins to prevent contrast-related kidney injury after coronary angiography or PCI

FLOzins for pREveNtion of Contrast-inducEd Acute Kidney Injury (FLORENCE) Study

Observational Collegium Medicum w Bydgoszczy · NCT07231939

This project tests whether taking a flozin (empagliflozin or dapagliflozin), short-term or long-term, lowers the chance of contrast-induced acute kidney injury in patients having coronary angiography or PCI.

What this trial studies

This is a retrospective, single-centre cohort/case-control analysis of all consecutive patients who underwent coronary angiography or PCI at Collegium Medicum w Bydgoszczy between 01.01.2020 and 30.09.2025. The final analysis includes only procedures with iodine contrast volume between 50 and 500 mL and patients with both pre- and post-procedure serum creatinine measurements. The study compares occurrence of contrast-induced AKI among patients with short-term versus long-term SGLT2 inhibitor (empagliflozin or dapagliflozin) use and will analyze baseline characteristics, contrast type and volume, and serial creatinine/eGFR changes at 24, 48, and 72 hours. Results will be combined with previously published studies in a planned meta-analysis.

Who should consider this trial

Good fit: Ideal candidates for inclusion are patients who underwent coronary angiography or PCI at Collegium Medicum w Bydgoszczy during the study period with documented contrast volume between 50 and 500 mL and available pre- and post-procedure serum creatinine measurements.

Not a fit: Patients with contrast volumes under 50 mL or over 500 mL, or with missing creatinine data, are excluded and therefore would not benefit from this analysis.

Why it matters

Potential benefit: If successful, using flozins around the time of contrast exposure could reduce cases of contrast-induced AKI and related short-term kidney complications in patients undergoing coronary angiography or PCI.

How similar studies have performed: Some observational and mechanistic studies suggest SGLT2 inhibitors have renal protective effects, but direct evidence specifically preventing contrast-induced AKI is limited and this study adds to a relatively small body of data.
