    Background And AimsBoth type 2 diabetes and cardiovascular (CV) disease develops at a younger age in Asians and often have a higher risk of mortality. Both sodium-glucose co-transport-2 inhibitors (SGLT-2Is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) have shown a significant reduction in CV end-points in CV outcome trials (CVOTs). Whether similar CV benefit exists in Asians, is not yet clearly known.MethodsWe systematically searched relevant medical database up to January 31, 2020 and retrieved all the dedicated CVOTs conducted with SGLT-2Is and GLP-1RAs. Subsequently, we meta-analyzed the pooled data of hazard ratio (HR) of major adverse cardiac events (MACE) in Asians. We additionally analyzed the data of heart failure hospitalization (HHF) or CV-death with SGLT-2Is in Asians.ResultsThe meta-analysis of three CVOTs conducted with SGLT-2Is (N = 4987), did not find any significant reduction in MACE (HR, 0.88; 95% CI, 0.67 to 1.15; P = 0.35) and HHF or CV-death (HR, 0.86; 95% CI, 0.55 to 1.36; P = 0.53) in Asians, compared to the placebo. In contrast, the meta-analysis of seven CVOTs conducted with GLP-1RAs (N = 4298) demonstrated a significant reduction in MACE, compared to the placebo (HR, 0.71; 95% CI, 0.59 to 0.86; P < 0.0001).ConclusionsThis meta-analysis found a significant reduction in MACE with GLP-1RAs but not with SGLT-2Is in Asians. No significant reduction in HHF or CV-death demonstrated either with SGLT-2Is in Asians. Whether these results are related to an inadequate statistical power, or due to underrepresentation of Asians, or a true ethnic difference, remains to be established.Copyright © 2020 Diabetes India.
