Abstract: Objective: To compare the risk of composite peripheral artery disease (PAD) surgical outcome, including peripheral revascularization and amputation procedures, between new users of sodium-glucose cotransporter 2 inhibitors (SGLT2is) and dipeptidyl peptidase 4 inhibitors (DPP-4is). Research desing and methods: This retrospective cohort study of U.S. veterans age ≥18 years with diabetes who received care from the Veterans Health Administration was performed from 1 October 2000 to 31 December 2021. Data were linked to Medicare, Medicaid, and the National Death Index. New use of SGLT2i or DPP-4i medications as an add-on to metformin, sulfonylurea, or insulin treatment alone or in combination was evaluated for an association with PAD surgical procedure for peripheral revascularization and amputation. A Cox proportional hazards model for time-to-PAD event analysis compared the risk of a PAD event between SGLT2is and DPP-4is in a propensity score-weighted cohort with a competing risk of death and allowance for events to occur up to 90 days or 360 days after stopping SGLT2is. Results: The weighted cohort included 76,072 SGLT2i vs. 75,833 DPP-4i use episodes. The median age was 69 years, HbA1c was 8.4% (interquartile range [IQR] 7.5-9.4%), and the median diabetes duration was 10.1 (IQR 6.6-14.6) years. There were 874 and 780 PAD events among SGLT2i and DPP-4i users, respectively, for an event rate of 11.2 (95% CI 10.5-11.9) and 10.0 (9.4-10.6) per 1,000 person-years (adjusted hazard ratio [aHR] 1.18 [95% CI 1.08-1.29]). When PAD events were allowed for 360 days after SGLT2i use ended, the aHR was 1.16 (95% CI 1.06-1.26). Conclusions: SGLT2i as an add-on diabetes therapy was associated with an increased cause-specific hazard of PAD surgeries compared with DPP-4i.
