Although diabetes mellitus has long been known to significantly increase the risk of cardiovascular disease (CVD), 1 traditional anti-hyperglycemic medications have failed to improve cardiovascular (CV) outcomes. 2-4 However, in the past 4 years, major breakthroughs have been made in this field. Two new classes of antihyperglycemia medications, sodium-glucose cotransporter-2 inhibitors (SGLT2is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs), have recently been shown to improve not only glycemic control but also CV outcomes in patients with type 2 diabetes mellitus (T2DM). Because the proportion of patients with T2DM undergoing coronary artery bypass grafting (CABG) and other surgeries is rapidly increasing, 5 surgeons will begin to encounter these medications with greater frequency. Here we review the essential information that surgeons need to be aware of as they participate in the teambased care of patients with T2DM and CVD. EVIDENCE OF CV BENEFITS WITH SGLT2is SGLT2is inhibit glucose reabsorption and increase glucose excretion in the kidney, thus leading to so-called sweet pee and improved glycemic control. 6 Three CV outcomes trials with SGLT2is have been published to date (Table 1), 7-13 and all have shown CV benefits. In the Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients trial, 7020 patients with T2DM and known CVD were randomized to empagliflozin or placebo. 7 After a median of 3.1 years, the primary end point of 3-point major adverse cardiovascular events (MACE) (ie, CV death, myocardial infarction [MI], or stroke) was significantly reduced with empagliflozin treatment (hazard ratio [HR], 0.86; 95% confidence interval [CI], 0.74-0.99; P<.04). This was largely driven by a reduction in CV death (HR, 0.62; 95% CI, 0.49-0.77; P <.001). Of note, significant reductions in all-cause mortality (32%) and heart failure (HF) (35%) were also observed. Canagliflozin was evaluated in the Canagliflozin Cardiovascular Assessment Study (CANVAS) program, which consisted of 2 sister trials (CANVAS and CANVAS-Renal) in primary and secondary prevention patients with T2DM. 8 Over a median follow-up of 3.6 years, 3-point MACE was significantly reduced with canagliflozin (HR, 0.86; 95% CI, 0.75-0.97; P ¼ .02). Other exploratory outcomes indicated a potential benefit for death from HF (HR, 0.78; 95% CI, 0.67-0.91) and for a composite outcome of progression of renal disease (HR, 0.60; 95% CI, 0.47-0.77). An approximately 2-fold increase in the risk for lower-leg amputations was observed with canagliflozin (HR, 1.97; 95% CI, 1.41-2.75). The final SGLT2i with published CV outcomes data is dapagliflozin, which was evaluated in the Dapagliflozin Effect on Cardiovascular Events-Thrombolysis in Myocardial Infarction 58 trial. 9 This trial differed from the others in that it enrolled a ''healthier'' population (approximately 60% were primary prevention patients, and all had an estimated creatinine clearance 60 mL/ min), and it evaluated coprimary end points of 3-point MACE and a composit...
