The purpose of this study is to compare the incidence of contrast-induced nephropathy (CIN) following percutaneous coronary intervention (PCI) in patients on sodium-glucose cotransporter-2 (SGLT-2) inhibitors prior to the procedure with a matched cohort of patients not receiving sodium-glucose cotransporter-2 inhibitor therapy.

In this retrospective observational study, patients were eligible for inclusion if they underwent PCI at any of the included study centers within the study time period. Patients were assigned to either the SGLT-2 inhibitor group or control group depending on the documentation of receiving any SGLT-2 inhibitors within 24 h prior to PCI. Propensity matching was utilized to determine the final subjects to include for comparison. The primary outcome was the incidence of CIN.

A total of 192 patients (96 in each group) were matched after exclusion criteria were applied. The incidence of contrast-induced nephropathy was similar between groups, occurring in 8 (8.3%) patients in the SGLT-2 inhibitor group and 6 (6.3%) patients in the comparator group (p = 0.58). There was also no difference between groups in the change in serum creatinine following PCI.

Based on our analysis, we did not identify any risk of CIN associated with SGLT-2 inhibitor use prior to PCI. Based on these results and in conjunction with previously published literature, the use of SGLT-2 inhibitors appears safe prior to PCI. These results still warrant further investigation with prospective adequately powered studies to evaluate the incidence of CIN with SGLT-2 inhibitor use in the setting of PCI.
