MON-LB029 The Influence of SGLT-2 Inhibitors and Other Glucose-Lowering Therapies on All-Cause Mortality Risk and Cardiovascular Outcomes in Older Patients with Newly Treated Type 2 Diabetes: A Population-Based Cohort Study

Background: SGLT-2 inhibitors (SGLT-2i) have been associated with decreased all-cause mortality and cardiovascular (CV) morbidity in patients with type 2 diabetes (T2DM) and established CV disease in randomized trials. The objective of this study was to evaluate exposure time to SGLT-2i and other di...

description Background: SGLT-2 inhibitors (SGLT-2i) have been associated with decreased all-cause mortality and cardiovascular (CV) morbidity in patients with type 2 diabetes (T2DM) and established CV disease in randomized trials. The objective of this study was to evaluate exposure time to SGLT-2i and other diabetic therapies on all-cause mortality and cardiovascular outcomes in elderly patients with newly diagnosed T2DM. Methods: We conducted a retrospective analysis of patients > 67 years of age who were started on a glucose lowering drug (GLD) between August 1, 2015 and January 1, 2017 using population-based health administrative data. The primary outcome was time to death from any cause. Exposure to all drugs was captured as time-dependent covariates. Secondary outcomes included time to admission to hospital for a cardiovascular outcome. Results: During the study, 36,021 individuals started an GLD. The prevalence of MI and CHF at baseline were low (6.4% vs 9.2% respectively). SGLT-2i were first-line treatment in 3.5% of patients and 7.1% of patients were exposed at any time during the study period. The SGLT-2i group was younger (71.9+/-4.6 yrs vs 74.7+/- 6.2 yrs) with a higher prevalence of MI at baseline. In contrast to other GLDs, death risk decreased as the proportion of observation exposed to SGLT-2i and biguanides increased. The association between individual drug exposures and cardiovascular outcomes was similar. Discussion: In contrast to previous cohort studies, this study examined the independent influence of both SGLT-2i and all other possible GLD individually on mortality and CV risk and based on exposure time. This study suggests that SGLT-2i and biguanides are associated with a decreased risk of all-cause mortality and CV outcomes in patients newly diagnosed with T2DM. Further research is needed to elucidate the mechanism by which SGLT-2i improves mortality and CV outcomes.

Abstracts presented at a news conference are embargoed until the date and time of the news conference.
