Injectable GLP-1 receptor agonists reduce major adverse cardiovascular events. Yet for many individuals, injection hesitancy remains a significant barrier to long-term adherence. Orforglipron is a novel once-daily oral non-peptide GLP-1 receptor agonist designed to provide comprehensive cardiometabolic risk reduction. METHODS: PRISMA-compliant systematic review and meta-analysis (PROSPERO CRD420251229397) of placebo-controlled phase 2 and phase 3 trials of orforglipron. Random-effects models were used to pool mean differences (MD) and risk ratios (RR) with 95% confidence intervals. RESULTS: Across four large trials, orforglipron produced dose-dependent, clinically meaningful improvements in major modifiable cardiovascular risk factor compared with placebo: body weight − 6.08% (95% CI − 7.68 to − 4.47; up to − 9.31% at higher doses), HbA1c − 0.85% (95% CI − 1.53 to − 0.18; up to − 1.36%), systolic blood pressure − 4.32 mmHg (95% CI − 5.61 to − 3.03; up to − 5.78 mmHg at 45 mg), LDL-cholesterol − 4.14% (95% CI − 6.38 to − 1.91), triglycerides − 10.90% (95% CI − 14.36 to − 7.43), VLDL-cholesterol − 10.81% (95% CI − 14.10 to − 7.51), and HDL-cholesterol + 3.31% (95% CI + 1.66 to + 4.97). Notably, heterogeneity was very low to absent (I² = 0%) for systolic blood pressure and all lipid outcomes. Gastrointestinal side effects were common but typical of the GLP-1 class (nausea RR 5.22, vomiting RR 3.24, eructation RR 6.80). CONCLUSION: Orforglipron provides highly consistent reductions across the full spectrum of ASCVD risk factors, with effect sizes on lipids and blood pressure comparable to those linked to MACE reduction in trials of injectable GLP-1 receptor agonists. As a novel small-molecule GLP-1 agonist in its class, Orforglipron offers a transformative option for comprehensive cardiometabolic risk reduction and ASCVD prevention in patients with obesity and type 2 diabetes. </p>","PeriodicalId":521069,"journal":{"name":"Cardiovascular diabetology.

The presence of cardiac autonomic neuropathy (CAN) may contribute to CVD, but CAN is reversible, and it may improve following weight loss. Semaglutide, a GLP-1 receptor agonist (GLP-1RA), induces weight loss and improves cardio-metabolic risk factors. Therefore, this study evaluated the impact of semaglutide on CAN in individuals with schizophrenia. METHODS: We conducted a double-blind, randomized, placebo-controlled trial with 154 adults (18–60 years, BMI ≥27 kg/m2) who were receiving treatment with second-generation antipsychotics (SGAs) for schizophrenia and prediabetes (HbA1c: 39–47 mmol/mol). Participants were randomized (1:1) to receive once-weekly semaglutide or placebo (titrated to 1.0 mg or maximally tolerated dose) for 30 weeks. RESULTS: A total of 141 participants completed the trial (semaglutide: 74; placebo: 67). CAN prevalence was high (84%), with 50% of the participants showing definite CAN. CAN prevalence increased with obesity: the risk of having definite CAN increased significantly from BMI 30–35 kg/m2 and to BMI > 35 kg/m2 (p < 0.001). Clozapine treatment was associated with CAN (p < 0.001). Semaglutide treatment for 30 weeks reduced BMI by 2.86 kg/m2 but did not alter CAN levels (p = 0.516). No significant changes were observed in the placebo group. INTERPRETATION: CAN is highly prevalent in patients with schizophrenia, and CAN correlates with BMI and clozapine treatment. Although semaglutide reduced BMI, CAN remained unchanged, despite its relationship with BMI. Thus, longer periods with semaglutide treatment may be required before CAN improves.

However, their prospective associations with the incidence of hypertension among middle-aged and elderly adults are insufficiently characterized. METHODS: We analysed 4,541 participants aged 45 years or older, with no history of hypertension at baseline, from the China Health and Retirement Longitudinal Study (CHARLS). Cox proportional hazards regression and restricted cubic spline (RCS) regression analyses were applied to assess the associations between the novel TyG-related indices and incident hypertension. Time-dependent ROC curves were used to assess the predictive discriminatory ability of the model at different time points over time. We used the NRI and IDI to evaluate the improvement in risk prediction capability of TyG-related indices compared to the TyG index alone and BMI. The robustness of the study findings was examined, to some extent, through subgroup and sensitivity analyses. RESULTS: In the longitudinal analysis, 1,484 participants (32.7%) experienced an new-onset hypertension. In fully adjusted models, each 1-SD increase in TyG–BRI, TyG–ABSI, TyG–WWI, and TyG–CVAI was associated with hypertension hazards of 1.21 (95% CI, 1.14–1.28), 1.09 (1.03–1.16), 1.12 (1.05–1.19), and 1.21 (1.18–1.28), respectively. RCS analysis revealed a significant positive linear association between TyG-related indices and the risk of incident hypertension. The time-dependent ROC curves demonstrated that TyG-BRI and TyG-CVAI consistently exhibited higher AUC values over time compared with TyG-ABSI and TyG-WWI, indicating better discriminatory performance, although the Delong test suggested that these differences were not statistically significant in most cases. TyG-BRI and TyG-CVAI demonstrated better predictive performance compared to the TyG index and base model, as evidenced by higher improvements in both NRI and IDI across multiple follow-up periods.

This study aimed to investigate the link between CAS and T2D by identifying novel risk factors and examining the relationship between autonomic dysfunction (via heart rate variability, HRV) and systemic inflammation. METHODS: We conducted a retrospective observational study of 232 T2D patients, categorized into three groups based on carotid ultrasound: normal arteries (n = 47), intima-media thickening (n = 49), and carotid plaques (n = 136). Differences in clinical and inflammatory markers across groups were analyzed. Independent risk factors for CAS were identified using multivariate logistic regression, and a predictive model was developed and evaluated by Receiver Operating Characteristic (ROC) curve analysis. To infer causality, a bidirectional two-sample Mendelian randomization (MR) analysis was performed using summary-level data from large-scale genome-wide association studies (GWAS). RESULTS: Significant differences were observed in age, insulin usage, and inflammatory markers (NLR, PLR, LMR) among the groups (all p < 0.05). Logistic regression identified age, SDNN (a measure of HRV), LMR, and hs-CRP as independent risk factors for CAS. The combined model integrating hs-CRP, SDNN, and LMR demonstrated exceptional predictive accuracy for CAS (AUC = 0.941; 95% CI: 0.912–0.969). MR analysis provided genetic evidence supporting a causal relationship between genetically predicted HRV reduction and increased carotid intima-media thickness.
