Use of Flozins (Empagliflozin/Dapagliflozin) for Prevention of AKI (FLORENCE)

November 14, 2025 updated by: Jacek Kubica, Collegium Medicum w Bydgoszczy

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

All consecutive patients hospitalized from 01.01.2020 to 30.09.2025 who underwent coronary angiography or PCI will be eligible for inclusion.

The final analysis will be limited to individuals in whom the volume of ICM administered during the index procedure was between 50 and 500 mL and for whom both pre- and post-procedure serum creatinine measurements were available.

The primary objective of the study is the effect of short-term and long-term SGLT2i therapy on the occurrence of CI-AKI in patients undergoing diagnostic or therapeutic procedures with ICM.

Study Overview

Detailed Description

The use of radiological imaging methods requiring iodine-based contrast media (ICM) has been steadily increasing in recent years. Contrast-induced acute kidney injury (CI-AKI), formerly referred to as contrast-induced nephropathy (CIN), is one of the most common causes of acute kidney injury in patients undergoing diagnostic or therapeutic procedures involving ICM.

The study was designed as a retrospective, single-centre, cross-sectional, cohort, case-control study. All consecutive patients hospitalized from 01.01.2020 to 30.09.2025 who underwent coronary angiography or PCI will be eligible for inclusion. The final analysis will be limited to individuals in whom the volume of ICM administered during the index procedure was between 50 and 500 mL and for whom both pre- and post-procedure serum creatinine measurements were available.

The primary objective of the study is the effect of short-term and long-term SGLT2i therapy on the occurrence of CI-AKI in patients undergoing diagnostic or therapeutic procedures with ICM.

The analysis of the baseline characteristics of the study population is planned.

Based on the results of the study, a meta-analysis combining the results of previously published studies with those of the present study will be performed.

Key variables to be analyzed: type and volume of ICM; serum creatinine concentration at baseline, 24 h, 48 h, and 72 h after the procedure; eGFR at baseline, 24 h, 48 h, and 72 h; use of SGLT2i within 3 days prior to the procedure; long-term use of SGLT2i; type of SGLT2i administered.
