Abstract

BACKGROUND: Insulin resistance is a serious public health concern. The triglyceride-glucose (TyG) index is a simple, cheap, and reproducible surrogate of insulin resistance, and sodium-glucose cotransporter-2 (SGLT2) inhibitors have reshaped cardio-metabolic care beyond glycemic control. METHODS: We followed PRISMA and registered the protocol in PROSPERO (CRD420251056341). We searched PubMed, Scopus, Web of Science, EMBASE, and Cochrane from inception to May 31st, 2026, including observational studies and clinical trials reporting baseline and follow-up TyG in adults. Two reviewers screened records, a third resolved disagreements, data were extracted with a standardized form, and quality was assessed with Cochrane RoB 2.0, the Newcastle-Ottawa Scale, and the JBI checklists. The primary outcome was within-group change in TyG pooled with random-effects (Hartung-Knapp); tests were two-sided with a significance threshold of 0.05. RESULTS: Twelve studies comprising thirteen study arms were included, with a total of 1845 participants. Follow-up ranged from 12 weeks to 5 years. Across studies, SGLT2 inhibitor therapy was associated with a significant reduction in TyG index (mean difference = -0.28, 95% confidence interval [-0.41; -0.14], I2 = 99.5%). Egger's test suggested possible small-study effects, whereas Begg's test and trim-and-fill analysis did not show clear evidence of publication bias; leave-one-out analyses showed that no single study materially influenced the pooled estimate. CONCLUSION: Despite heterogeneity in populations, drug choice, and follow-up duration, SGLT2 inhibitors were associated with a significant decrease in TyG, although small-study effects cannot be excluded.

Efficacy of sodium-glucose cotransporter 2 inhibitors after acute myocardial infarction: Are the benefits limited to patients with diabetes? A systematic review and meta-analysis.

BACKGROUND: Acute myocardial infarction remains one of the leading causes of death worldwide. Recently, studies have focused on evaluating the effectiveness of SGLT2 inhibitors in this scenario. Objectives We aimed to perform a meta-analysis comparing the efficacy of SGLT2 inhibitors vs standard care. METHODS: We systematically searched PubMed, Embase, and Cochrane for randomized controlled trials (RCTs) and observational studies comparing patients with acute myocardial infarction using iSGLT2 inhibitors and standard care. Statistical analyses were conducted using R software (v 4.3.2) and a random-effects model was employed for all outcomes. RESULTS: A total of 31,378 patients were included, with 10,897 (34.7%) assigned to the SGLT2 inhibitor group. Among these studies, three were randomized controlled trials (RCTs). There was a significant difference in reduction of HF readmissions (OR 0.61; p&#xa0;<&#xa0;0.01), all-cause mortality (OR 0.62; p&#xa0;<&#xa0;0.01;) and stroke (OR 0.67; p&#xa0;<&#xa0;0.01;). However, there was no significant difference in cardiovascular death, rehospitalization for any cause and recurrence of acute MI. Meta regression and subgroup analysis showed a trend toward better outcomes in the diabetic and non-STEMI population. CONCLUSIONS: SGLT2 inhibitors were associated with lower HF rehospitalization, stroke, and all-cause mortality after acute MI, mainly in observational studies. Benefits appeared greater in diabetic and non-STEMI patients. Dedicated RCTs focusing on diabetic, particularly non-STEMI, populations are needed to confirm these findings. KEY POINTS: What is already known on this topic: SGLT2 inhibitors have demonstrated cardiovascular and renal benefits in patients with heart failure and type 2 diabetes mellitus. However, their role in the acute myocardial infarction (AMI) setting remains uncertain, particularly regarding post-AMI outcomes such as heart failure readmissions, mortality, and recurrent ischemic events, with current evidence derived from heterogeneous and predominantly observational studies. WHAT THIS STUDY ADDS: This meta-analysis, including over 31,000 patients, suggests that SGLT2 inhibitors are associated with reductions in heart failure readmissions, all-cause mortality, and stroke following AMI. These associations were more consistently observed in patients with type 2 diabetes and in non-ST-segment elevation myocardial infarction (NSTEMI) populations. However, randomized controlled trials showed neutral results, and the observed benefits were mainly driven by observational studies. Meaning: These findings should be interpreted as hypothesis-generating. While SGLT2 inhibitors may represent a potential therapeutic strategy in selected post-AMI populations, particularly patients with diabetes and NSTEMI, current evidence does not support routine early in-hospital initiation. Dedicated randomized trials specifically enrolling diabetic post-AMI patients are required to clarify optimal timing and clinical benefit.

Effects of semaglutide and empagliflozin on markers of endothelial function in persons with type 2 diabetes: A post hoc analysis of a randomized clinical trial.

AIMS: The endothelium maintains vascular health by regulating blood flow and protecting against inflammatory damage. In type 2 diabetes (T2DM), however, hyperglycemia, hypertension, and hyperlipidemia place a significant burden on the endothelium, potentially leading to atherosclerosis and cardiovascular disease (CVD). While semaglutide and empagliflozin have been shown to reduce CVD risk in T2DM, it remains unclear whether these benefits are mediated by improved endothelial function. This post-hoc analysis explores the effects of these agents on markers of endothelial function, i.e. the reactive hyperaemic index (RHI) and the endothelial-derived cell adhesion molecules (CAMs) E-Selectin, ICAM-1, P-Selectin, and VCAM-1. METHODS: This was a post-hoc analysis of a 32-week randomized trial evaluating the separate and combined effects of semaglutide and empagliflozin on cardio-renal organ damage. One hundred and twenty participants with type 2 diabetes, age&#xa0;&#x2265;&#xa0;50 were randomized to four groups (semaglutide, empagliflozin, the combination or placebo). An increase in RHI and/or a decrease in CAMs were considered beneficial. RESULTS: RHI increased compared to baseline (0.11, 95%CI [0.008;0.21], p&#xa0;=&#xa0;0.03) but not compared to placebo in the semaglutide group (0.11, 95%CI [-0.04;0.24], p&#xa0;=&#xa0;0.16). There was no effect on RHI in the empagliflozin group. Compared to placebo, E-Selectin decreased significantly in the semaglutide and combination groups (-9, 95%CI [-14.1;-5.1] p&#xa0;<&#xa0;0.01 and&#xa0;-&#xa0;9, 95%CI [-14.3; -5.2] p&#xa0;<&#xa0;0.01, respectively). VCAM-1 increased in the same groups, compared to placebo (12.3, 95%CI[2.8;20.8] p&#xa0;=&#xa0;0.01 and 16.2, 95%CI [7.2;24.3], p&#xa0;<&#xa0;0.01, respectively).P-Selectin and ICAM-1 was not significantly affected in any of the groups, compared to placebo (p&#xa0;&#x2265;&#xa0;0.11 and p&#xa0;&#x2265;&#xa0;0.09, respectively). CONCLUSION: Semaglutide improved endothelial function compared to baseline, but not significantly versus placebo, which likely is due to limited power. CAM responses were heterogeneous, suggesting distinct roles in endothelial dysfunction and atherosclerosis. ClinicalTrialsRegister.eu: EudraCT 2019-000781-38.

From pathobiology to prescribing in obesity-driven HFpEF: A systematic review and practical therapeutic framework.

Heart failure with preserved ejection fraction (HFpEF) is increasingly driven by obesity and cardiometabolic dysfunction. In this phenotype, the dominant biology extends beyond congestion alone and includes visceral and epicardial adiposity, systemic inflammation, impaired myocardial energetics, endothelial dysfunction, and exertional elevation in filling pressures. We performed a PRISMA-compliant systematic review with structured narrative evidence synthesis to evaluate pharmacological therapy in obesity-driven HFpEF, searching PubMed/MEDLINE, Scopus, Web of Science Core Collection, ClinicalTrials.gov, and WHO ICTRP through December 2025. Eighteen reports were included in the final qualitative synthesis. The available evidence supports sodium-glucose cotransporter 2 inhibitors as the pharmacological foundation because they provide the most mature outcome data across the preserved ejection fraction spectrum. Semaglutide improves symptoms, physical limitations, exercise capacity, and body weight in dedicated obesity-related HFpEF trials, whereas tirzepatide extends this signal by improving clinical status and reducing worsening heart failure events. Finerenone broadens the therapeutic platform in HF with mildly reduced or preserved ejection fraction, although obesity-specific data remain indirect. Conventional neurohormonal therapies retain a selective role, but they are not the principal biological match for this phenotype. Obesity-driven HFpEF should therefore be managed as a cardiometabolic syndrome with heart failure expression, using a phenotype-based sequence that links diagnosis, decongestion, SGLT2 inhibition, obesity-directed therapy, and selective adjunctive intensification.
