Combination cardiometabolic therapy in type 2 diabetes: optimizing SGLT2 inhibitor and GLP‑1 receptor agonist use

To evaluate the evidence supporting combined sodium-glucose cotransporter 2 inhibitors (SGLT2is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) in type 2 diabetes, focusing on cardiometabolic outcomes and practical treatment approaches. Cardiovascular outcomes trials and real-world studies indicate that SGLT2is and GLP-1RAs confer complementary, non-redundant cardiovascular, kidney, and metabolic benefits. SGLT2is primarily reduce hospitalization for heart failure and slow kidney disease progression, while GLP-1RAs more effectively reduce atherosclerotic events, particularly stroke; dedicated kidney-outcome and heart-failure trials of GLP-1RAs in chronic kidney disease and obesity-related heart failure with preserved ejection fraction have further broadened their role. Randomized data show that each class retains its benefit irrespective of background use of the other, supporting independent mechanisms; whether this translates into reductions in hard outcomes is being tested prospectively. Emerging evidence supports a phenotype-guided approach that aligns therapy with dominant comorbidities such as atherosclerotic cardiovascular disease, heart failure, chronic kidney disease, and obesity. Despite advances in pharmacotherapy, substantial cardiometabolic risk remains in type 2 diabetes. Combined SGLT2i and GLP-1RA therapy addresses multiple risk domains through complementary mechanisms and may be most effective within a phenotype-guided framework. This framework prioritizes therapy according to predominant comorbidity and reserves combination treatment for individuals with overlapping high-risk phenotypes.
