Background And Purpose: We investigated whether circulating microRNAs (miRNAs) is associated with arterial stiffness in patients with acute ischemic stroke.
Methods: We recruited patients with acute ischemic stroke who were admitted to a university hospital stroke center and underwent carotid-femoral pulse wave velocity (cfPWV) measurement using SphygmoCor (AtCor Medical, Sydney, Australia) and brachial-ankle PWV using a volume-plethysmography device (VP-1000, Omron Colin, Komaki, Japan). Circulating miRNAs were measured in venous blood samples stored in EDTA. We selected five miRNAs (miR-17, miR-93, miR-450, miR-629, and let-7i) related to atherosclerosis based on a literature review. Pearson's correlation analysis was applied to the correlations between miRNAs and arterial stiffness parameters. Finally, multivariable linear regression analysis was performed to identify the independent factors for cfPWV.
Results: This study included 70 patients (age=71.1±10.3 years [mean±SD], 29 females). The expression levels of miR-93 (=-0.27, =0.049) and let-7i (=-0.27, =0.039) were inversely correlated with cfPWV. Multivariable linear regression analysis including age, hypertension, and estimated glomerular filtration rate showed that let-7i was independently related with cfPWV (standardized coefficient=-0.262, =0.036). Correlation analysis indicated that let-7i was positively associated with visceral muscle Hounsfield units on computed tomography (=0.264, =0.043).
Conclusions: The expression level of let-7i was independently related to arterial stiffness in patients with cerebral infarction, suggesting that it plays a pathophysiological role in atherosclerosis.

Heart failure with preserved ejection fraction (HFpEF) accounts for nearly half of all heart failure cases and is increasing in prevalence due to aging populations and comorbidities such as hypertension and diabetes. While echocardiography remains the diagnostic cornerstone, many patients with preserved ejection fraction present with nonspecific symptoms and ambiguous diastolic indices, leading to diagnostic uncertainty and therapeutic delay. Arterial stiffness-quantified by pulse wave velocity, augmentation index, and cardio-ankle vascular index)-is emerging as a key contributor to HFpEF pathophysiology.

Background: In adults without cardiovascular disease (CVD), there is limited understanding of the association between overall cardiovascular health (CVH) and arterial health.
Methods: In 2330 Framingham Heart Study Offspring participants free of CVD (60±9 years; 57% women) with Life's Essential 8 (LE8) and applanation tonometry data (Exam 7), we calculated CVH scores per American Heart Association's LE8 guidelines. Multivariable-adjusted regression analyses examined the relations of LE8 with aortic stiffness and pressure pulsatility [negative inverse carotid-femoral pulse wave velocity (niCFPWV), central pulse pressure (CPP), respectively], and examined effect modification by age and sex.

Context: Cardiometabolic complications are increasingly recognized in congenital adrenal hyperplasia (CAH) due to 21β-hydroxylase deficiency, but adult data remain limited.
Objective: To evaluate cardiovascular and metabolic alterations in adult patients with classic CAH under glucocorticoid treatment, compared to matched controls.
Methods: A cross-sectional study was conducted on adults with classic CAH and sex- and BMI-matched controls.

Neutrophil extracellular trap (NET) formation, or NETosis, is a key innate immune response that contributes to cardiovascular diseases, including vascular inflammation, atherosclerosis, and thrombosis. In the cardiovascular system, neutrophils encounter mechanical cues such as shear stress, matrix stiffness, and cyclic stretch that influence their activation and NET release. This review examines emerging evidence linking altered mechanotransduction to dysregulated NETosis in vascular aging and cardiovascular pathology.

Background: Arterial stiffness, assessed via carotid femoral pulse wave velocity (cfPWV), is a marker of vascular aging that may contribute to cognitive decline. Serum carotenoids, with antioxidant properties, may mitigate these effects, but their role in moderating neurovascular-cognitive relationships remains unclear.
Objective: This study examined: (1) associations between cfPWV and executive function, (2) the contribution of serum carotenoids in predicting cfPWV, and (3) whether carotenoids moderate the relationship between cfPWV and executive function.
