Comparison of cardiovascular outcomes of new antihyperglycemic agents in Type 2 Diabetes Mellitus: a meta‐analysis

Abstract

Aims

The study aims to provide comprehensive evidence for the selection of agents in type 2 diabetes mellitus (T2DM) patients with cardiovascular risk and summarize the lasted evidence for the cardiovascular effects of sodium glucose cotransporter‐2 inhibitor (SGLT2i) in patients with heart failure (HF).

Methods and results

Several online databases were searched. All studies that explored the cardiovascular effects of SGLT2i or glucagon‐like peptide 1 receptor agonist (GLP1‐RA) were screened and reviewed. A total of 38 studies were included. Compared with GLP1‐RA, the use of SGLT2i significantly reduced the risk of cardiovascular death [risk ratio (RR) = 0.59; 95% confidence interval (CI), 0.44–0.58], hospitalization of heart failure (HHF) (RR = 0.77; 95% CI, 0.74–0.80), death from any cause (RR = 0.64; 95% CI, 0.60–0.68), and myocardial infarction (MI) (RR = 0.81; 95% CI, 0.76–0.87). However, SGLT2i significantly increased the risk of stroke (RR = 1.10; 95% CI, 1.04–1.17). Compared with the control group, SGLT2i treatment reduced the risk of cardiovascular death by 14% (RR = 0.86; 95% CI, 0.79–0.94), HHF by 25%, and death from any cause by 9% in patients with HF, regardless of diabetes status.

Conclusions

SGLT2i is associated with a lower risk of cardiovascular death, HHF, death from any cause, and MI in patients with T2DM compared with GLP1‐RA. In addition, SGLT2i brought more benefits with respect to the effects of cardiovascular death, HHF, and death from any cause in patients with HF, regardless of diabetes status.
