Effect of SLGT2 Inhibitors on Patients with Atrial Fibrillation.

backgroundSodium glucose cotransporter 2 (SGLT2) inhibitors have been associated with various cardiovascular benefits. There is limited data examining the effect of these medications on atrial fibrillation (AF) associated clinical outcomes. We compared ischemic stroke, acute coronary syndrome (ACS), cardioversion, and all-cause mortality outcomes in AF patients on SGLT2 inhibitors to propensity matched controls. MATERIALS AND

methodsWe conducted a retrospective study with a global medical research network database. AF patients were identified via ICD codes that must have been present for at least one month. Patients on SGLT2 inhibitors were identified as those on dapagliflozin, empagliflozin, or canagliflozin for at least one month. AF patients on SGLT2 inhibitors were propensity matched to those not on SGLT2 inhibitors based on age, race, ethnicity, cardiovascular comorbidities, valvular disease, pulmonary disease, urinary diseases, cardiovascular procedures, cardiovascular medications, and anticoagulants. We examined incidence of ischemic stroke, at least one ACS episode, cardioversion, and all-cause mortality.

resultsIn 26,269 AF patients, SGLT2 inhibitors were associated with lower risk of cardioversion (HR 0.921, 95% CI 0.841 - 0.999, p = 0.0245) and all-cause mortality (HR 0.676, 95% CI 0.635 - 0.721, p < 0.0001). However, there was an association with increased risk for ischemic stroke (HR 1.081, 95% CI 1.012 - 1.154, p 0.0201). There was no clear association with ACS events.

conclusionsIn patients with AF, use of SGLT2 inhibitors was associated with a lower risk of cardioversion and all-cause mortality and higher probability of survival based on Kaplan-Meier analysis.
