Abstract P444: Changes in Glucose-Lowering Medication Prescriptions After an Incident Cardiovascular Event Across eGFR Levels in an Integrated Health System
Introduction: Cardiovascular disease is a major complication among patients with diabetes, and may merit changes in both antihypertensive medications (e.g., to beta blockers and ACE inhibitors) and glucose-lowering medications (e.g., to sodium-glucose cotransporter 2 inhibitors [SGLT2i] and glucagon-like peptide 1 receptor agonists [GLP1 RA], medication classes with evidence of cardiovascular outcome benefit). The objective of this study was to assess how glucose-lowering medication prescriptions changed after a cardiovascular event among persons with diabetes. Hypothesis: There are changes in glucose-lowering medication prescription following a cardiovascular event. Methods: We identified adult patients with diabetes and estimated glomerular filtration rate (eGFR)≥15mL/min/1.73 m 2 who experienced a cardiovascular event (myocardial infarction, stroke, or heart failure) from 2005-2018 in the Geisinger Health System (cases). We selected control patients with diabetes but without a cardiovascular event by 1:1 matching on demographics, diabetes duration, HbA1c, eGFR, and calendar year. Results: In 15,918 matched case and control patients with diabetes (mean age 65 years, 52% female, mean HbA1c 7.55%, median diabetes duration 5.6 years, and 28% eGFR<60 mL/min/1.73 m 2 ), insulin prescriptions increased and metformin prescriptions decreased after a cardiovascular event among cases compared with controls in all eGFR categories ( Table ). There were no differences between cases and controls with respect to changes in SGLT2i, GLP1 RA, or dipeptidyl peptidase 4 inhibitors (DPP4i). Conclusions: In a real-world setting, insulin prescriptions increased and metformin prescriptions decreased, after a cardiovascular event regardless of eGFR level. Prescriptions for SGLT2i and GLP1 RA did not change following a cardiovascular event in all eGFR categories. More efforts are needed to provide optimal therapies for cardiovascular risk reduction in patients with diabetes and cardiovascular disease.
