Materials and Methods PubMed and EMBASE were searched up to 22 August 2025 for placebo‐controlled randomized trials of oral or bolus‐type, subcutaneous GLP‐1RAs reporting major adverse cardiovascular events (MACE; a composite of cardiovascular death, myocardial infarction, and stroke) in adults with type 2 diabetes. The primary outcome was MACE; secondary outcomes included heart failure (HF) and kidney outcomes. Random‐effects meta‐analyses were followed by meta‐regression evaluating associations with HbA1c and bodyweight reduction. Results A total of 73 263 individuals were included from 10 trials (ELIXA, LEADER, SUSTAIN‐6, EXSCEL, Harmony Outcomes, PIONEER 6, REWIND, AMPLITUDE‐O, FLOW, and SOUL). GLP‐1RAs reduced MACE by 14% (hazard ratio: 0.86; 95% CI: 0.82 to 0.91; p <0.001), as well as hospitalisation for HF and the composite kidney outcome (both p <0.001). Meta‐regression showed that every 1% extra reduction in HbA1c corresponded to a 27% lower HR for MACE ( p = 0.015; R 2 = 0.61). While HbA1c reduction was not significantly associated with secondary outcomes, the directionality was consistent with MACE. Bodyweight change was not associated with any of the analysed endpoints, including MACE ( p = 0.13; R 2 = 0.21). Conclusions HbA1c reduction, not bodyweight change, was significantly and proportionally associated with MACE risk reduction. HbA1c lowering may serve as a useful surrogate for the cardiovascular improvements associated with GLP‐1RAs in type 2 diabetes. 10.1111/dom.70121 http://creativecommons.org/licenses/by-nc/4.0/ |
