Abstract: BACKGRUOUND: Patients with type 2 diabetes mellitus (T2DM) and coronary ischemia face an exceptionally elevated risk, and the achievement of complete revascularization (CR) within this population could be challenging. METHODS: Patients with T2DM and coronary ischemia based on coronary angiography and retrospective angiographic fractional flow reserve analysis between 2014 and 2016 were included. The impact of the extent of revascularization on the improvement of endpoint events by sodium-glucose cotransporter 2 (SGLT2) inhibitors was analyzed. The primary study endpoint was major adverse cardiac events (MACE), while all-cause mortality served as secondary endpoints. Kaplan-Meier analysis and Cox proportional hazards regression model were adopted to assess the association between SGLT2 inhibitors and endpoint incidence. RESULTS: A total of 671 patients were identified. Among them, 206 (30.7%) were prescribed with SGLT2 inhibitors, while 484 (72.1%) achieved CR after the operation. During a mean 36-month follow-up, 100 MACE and 89 all-cause mortality were recorded. SGLT2 inhibitor users demonstrated lower rates of MACE (8.3% vs. 17.8%, P=0.002) and all-cause mortality (6.3% vs. 16.3%, P<0.001) compared to non-users. After adjusting for confounding factors in multivariable Cox analysis, the association between SGLT2 inhibitors and reduced MACE incidence remained consistent both in the CR and incomplete revascularization subgroups (hazard ratio [HR], 0.498; 95% confidence interval [CI], 0.246 to 0.938; P=0.040; and HR, 0.341; 95% CI, 0.123 to 0.805; P=0.023, respectively). CONCLUSION: SGLT2 inhibitors were found to be associated with a reduced risk of 3-year MACE and all-cause mortality in patients with T2DM and coronary ischemia, regardless of extent of revascularization.
