Abstract
Purpose
Effects of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in type-2 diabetes mellitus (T2DM) with or without prior heart failure (HF) have been inconsistent across cardiovascular outcome trials. This study aimed to investigate the impact of HF history at baseline on cardiovascular effects of GLP-1 RAs in T2DM.
Methods
PubMed, Embase, Web of Science, and clinical trial registries were searched for randomized controlled trials (RCTs) or post hoc analyses (≥ 24 weeks) reporting HF hospitalizations and/or cardiovascular death (HHF/CVD), major adverse cardiovascular events (MACE) comprising of cardiovascular death, myocardial infarction, and stroke in adults with T2DM with or without HF history (PROSPERO:CRD42022367633). Hazard ratios (HRs) in GLP-1RAs versus placebo arms were pooled together using the generic inverse variance method in fixed-effects model. Subgroup analysis was performed.
Results
We identified 5 eligible studies, pooling data retrieved from six RCTs and 48,489 individuals with T2DM. On pooled analysis, GLP1RA treatment versus placebo significantly reduced risk of HHF/CVD in only T2DM without HF history (HR = 0.84; 95%CI, 0.77–0.91; I2 = 14%; p < 0.001), but not in those with HF history (HR = 0.96; 95%CI, 0.85–1.08; I2 = 14%; p = 0.4) (p-interaction < 0.1). GLP-1RAs reduced incident HHF in T2DM with or without HF history (HR = 0.89; 95%CI, 0.80–0.98; I2 = 41%; p < 0.05) (p-interaction = 0.28). Sensitivity analysis excluding REWIND trial accentuated the impact of baseline HF history on both HHF/CVD and HHF (p-interaction < 0.05). Benefits on MACE with GLP-1RAs were consistently seen in T2DM regardless of HF history (p-interaction = 0.8).
Conclusion
GLP-1RAs consistently prevented HF hospitalizations and MACE in T2DM regardless of baseline HF history, whereas significant attenuation of benefits on composite HHF/CV death were observed in those with HF history.
