Effect of new glucose-lowering drugs on stroke in patients with type 2 diabetes: A systematic review and Meta-analysis

Role of Residual Inflammation as a Risk Factor Across Cardiovascular-Kidney-Metabolic (CKM) Syndrome: Unpacking the Burden in People with Type 2 Diabetes

Type 2 diabetes mellitus (T2DM) is a global health crisis, with cardiovascular disease (CVD) accounting for 75% of mortality in this population. Despite advances in managing traditional risk factors, such as low-density lipoprotein cholesterol (LDL) cholesterol reduction (IMPROVE-IT, FOURIER), antithrombotic therapies (PEGASUS, COMPASS), and triglyceride-lowering agents (REDUCE-IT), a substantial residual cardiovascular risk persists, driven in part by chronic low-grade systemic inflammation. Chronic low-grade inflammation is a central driver of cardiovascular-kidney-metabolic (CKM) syndrome in T2DM, perpetuating residual cardiovascular risk despite optimal management of traditional risk factors. This narrative review synthesizes evidence on how inflammation accelerates coronary heart disease (CHD), heart failure (HF), stroke, diabetic kidney disease (DKD), and peripheral artery disease (PAD). We evaluate the anti-inflammatory mechanisms of current therapies such as statins, sodium-glucose cotransporter 2 (SGLT2) inhibitors, and glucagon-like peptide 1 (GLP-1) receptor agonists, as well as emerging agents like colchicine and interleukin (IL)-1β/IL-6 inhibitors, emphasizing their differential efficacy across CKM traits. By integrating pathophysiological insights with clinical trial data, we propose biomarker-guided strategies to target inflammation as a modifiable risk factor, offering a roadmap to bridge the gap in diabetes-related cardiovascular care.

Impact of GLP-1 Receptor Agonists on Psoriasis and Cardiovascular Comorbidities: A Narrative Review

Psoriasis is an immune-mediated skin disease known to be associated with a higher risk of cardiometabolic comorbidities such as hypertension, myocardial infarction, and stroke. GLP-1 receptor agonists (GLP-1RAs) are medications approved to treat type 2 diabetes mellitus and obesity and have been reported to improve psoriasis. As more psoriasis patients start GLP-1RAs for approved indications, it is of interest to understand the impact of GLP-1RAs on both psoriasis and associated cardiovascular risk. In this review, we examine the effect of GLP-1RAs on psoriasis and cardiovascular comorbidities-defined as hypertension, stroke, and myocardial infarction. The majority of case reports and prospective cohort studies found GLP-1RAs improved psoriasis, while two randomized controlled trials showed conflicting results. For cardiovascular disease, most studies found GLP-1RAs reduced systolic blood pressure, total stroke, and myocardial mortality. These results suggest that GLP-1RAs may be a particularly promising treatment for psoriasis patients with diabetes or obesity comorbidities, offering both cardioprotective benefits and potential improvement in psoriatic symptoms.

Geriatric Pharmacotherapy Case Series: Medications for Diabetes-A Focus on Secondary Stroke Prevention

This report addresses evidence for efficacy of diabetes medications with a focus on stroke risk reduction. The cardiovascular benefits of SGLT-2 inhibitors and GLP-1 receptor agonists have been well-established; however, clinical trials to date have examined composite cardiovascular endpoints that include, but do not specifically focus on, stroke. The purpose of this case review is to examine the evidence for the various diabetes medications in reducing the risk for stroke. This literature review was inspired by a patient seen in a geriatric day hospital program with diabetes and a history of multiple strokes. Our goal was to select a diabetes management regimen that would provide both glycemic control and stroke risk reduction. As diabetes and cerebrovascular disease commonly coexist and are important contributors to morbidity and mortality in older individuals, appropriate management must incorporate both current evidence as well as consideration for patient-specific factors that may influence the treatment plan. This patient case illustrates the importance of both.

Diabetes and Stroke: Impact of Novel Therapies for the Treatment of Type 2 Diabetes Mellitus

Type 2 diabetes mellitus (T2DM) is a significant risk factor for stroke. Nevertheless, the evidence supporting stringent glycemic control to reduce macrovascular complications, particularly stroke, is not as clear as for microvascular complications. Presently, risk reduction strategies are based on controlling multiple risk factors, including hypertension, dyslipidemia, glycemia, smoking, and weight. Since 2008, new pharmacological therapies for treating T2DM have been required to undergo trials to ensure their cardiovascular safety. Remarkably, several novel therapies have exhibited protective effects against the combined endpoint of major cardiovascular events. Evidence from these trials, with stroke as a secondary endpoint, along with real-world data, suggests potential benefits in stroke prevention, particularly with glucagon-like peptide 1 receptor agonists. Conversely, the data on sodium-glucose cotransporter type 2 inhibitors remains more controversial. Dipeptidyl peptidase 4 inhibitors appear neutral in stroke prevention. More recent pharmacological therapies still lack significant data on this particular outcome. This article provides a comprehensive review of the evidence on the most recent T2DM therapies for stroke prevention and their impact on clinical practice.

Do SGLT2 inhibitors and GLP-1 receptor agonists modulate differently the risk of stroke ? Discordance between randomised controlled trials and observational studies

Stroke represents a major burden in patients with type 2 diabetes, yet this cerebrovascular complication has been less carefully investigated than the risk of cardiovascular mortality, heart failure and renal disease. Some data suggested that glucagon-like peptide-1 receptor agonists (GLP-1RAs) exert a better protection against stroke than sodium-glucose cotransporter 2 inhibitors (SGLT2is). However, this conclusion was derived from indirect comparisons in absence of any head-to-head randomised controlled trial (RCT). The present comprehensive review compares the effects of SGLT2is versus GLP-1RAs on nonfatal and fatal/nonfatal strokes in network meta-analyses of RCTs (mostly cardiovascular outcome trials) versus placebo, on the one hand, and in real-life observational cohort studies, on the other hand. Whereas network meta-analyses of placebo-controlled RCTs confirm a slight but significant (in 11 out of 13 meta-analyses) higher incidence of stroke in patients treated with SGLT2is compared with those treated with GLP-1RAs, a large majority of retrospective observational cohort studies (19 out of 21) failed to find any significant difference in the risk of stroke between the two pharmacological classes. Available, yet limited, findings suggest that SGLT2is may be more efficacious against haemorrhagic than ischaemic strokes, in patients at risk for atrial fibrillation and in patients with chronic kidney disease.

SGLT2 Inhibitors vs. GLP-1 Agonists to Treat the Heart, the Kidneys and the Brain

Sodium glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like-peptide-1 receptor (GLP-1-R) agonists are novel therapeutic agents used for the management of type 2 diabetes mellitus (T2DM). Recently, large-scale randomized clinical trials have been conducted to assess the cardiovascular safety of these medications. The findings of these trials have revealed that both SGLT2 inhibitors and GLP-1-R agonists exhibit favorable cardioprotective effects, including reduction in cardiovascular and all-cause mortality, a decreased risk of chronic kidney disease progression, a decrease in hospitalization for heart failure (HF), an effect shown by SGLT2 inhibitors, and stroke prevention, an effect shown by GLP-1-R agonists. Based on the results from above studies, the European and American Diabetes Associations have issued new recommendations strongly endorsing the use of SGLT2 inhibitors and GLP-1-R agonists in combination with metformin for patients with T2DM who have additional cardiovascular (CV) comorbidities or risk factors. The primary aim of this combined therapy is to prevent CV events. Although both medication groups offer beneficial effects, they demonstrate slightly different profiles. SGLT2 inhibitors have exhibited better effects regarding a reduced incidence of HF, whereas GLP-1-R agonists have shown a reduced risk of CV events, particularly stroke. Moreover, recent European Society of Cardiology as well as American College of Cardiology and American Heart Association guidelines of HF treatment stressed the importance of SGLT2 inhibitor administration in patients with HF regardless of T2DM. In this context, we present and discuss the outcomes of the most recent trials investigating the impact of SGLT2 inhibitors and GLP-1-R agonists on renal and cardiovascular outcomes in patients, both with and without T2DM. Additionally, we explore the synergistic effects of combining SGLT2 inhibitors and GLP-1-R agonists in patients with cardiovascular disease.
