Metanálise em rede e emparelhada dos efeitos de novos hipoglicemiantes nos desfechos cardiorrenais em pacientes com diabetes tipo 2 e insuficiência cardíaca

Resumo original em inglês

O que aconteceu

This study aims to evaluate the cardiovascular and renal benefits of novel hypoglycemic agents, including glucagon-like peptide-1 receptor agonists (GLP-1RAs), dipeptidyl peptidase-4 inhibitors (DPP-4is), sodium-glucose cotransporter-2 inhibitors (SGLT-2is), and glucose-dependent insulinotropic polypeptide/glucagon-like peptide-1 dual receptor agonists (GIP/GLP-1RAs) in patients with type 2 diabetes mellitus (T2DM) and heart failure (HF).

Systematic literature searches were conducted in MEDLINE, Embase, ClinicalTrials.gov, and Cochrane Central Register of Controlled Trials (CENTRAL) from inception to 30 April 2026. Randomized controlled trials (RCTs) for cardiovascular outcomes (CVOTs) or post hoc analyses of CVOTs comparing SGLT-2is, DPP-4is, GLP-1RAs, or GIP/GLP-1RAs in patients with T2DM and HF were selected. Network meta-analysis was used for indirect comparisons, with results presented as hazard ratios (HRs) and 95% confidence intervals (CIs).

O que encontraram

A total of 10 RCTs and two post hoc analyses of CVOTs involving 13,886 patients were included. Compared with placebo, SGLT-2is (HR [95% CI]: 0.75 [0.68, 0.82]) and GLP-1RAs (HR [95% CI]: 0.77 [0.61, 0.97]) both significantly reduced the risk of HF-related composite endpoints in patients with T2DM and HF. No statistically significant difference was observed between SGLT-2is and GLP-1RAs (HR [95% CI]: 0.98 [0.76, 1.25]). SGLT-2is also reduced the risk of HF worsening (HR [95% CI]: 0.72 [0.53, 0.96]), HF hospitalization (HR [95% CI]: 0.74 [0.66, 0.83]), and cardiovascular (CV) death (HR [95% CI]: 0.87 [0.77, 0.98]). For all-cause death, SGLT-2is showed a trend toward reduced risk compared to placebo, but this difference did not reach statistical significance (HR [95% CI]: 0.83 [0.67, 1.02]). For the renal composite outcome, SGLT-2is did not demonstrate a statistically significant benefit (HR [95% CI]: 0.76 [0.51, 1.14]).

Por que isso importa

Optimal clinical management of T2DM requires a comprehensive assessment of cardiovascular and renal comorbidities. This network meta-analysis indicates that SGLT-2is significantly reduce the risk of HF-related composite endpoints and CV death in T2DM patients with HF, although their renoprotective effect does not reach statistical significance. GLP-1RAs also demonstrate beneficial effects on HF-related composite endpoints. These findings suggest that both SGLT-2is and GLP-1RAs are preferred glycemic control strategies for improving cardiovascular outcomes in T2DM patients with HF, while further evidence is needed to confirm their definitive renal benefits.
