Background: Little is known about the characteristics of arterial stiffness in heart failure (HF). This study was performed to compare the degree of arterial stiffness and its association with left ventricular (LV) diastolic function among three groups: control subjects, patients with HF with reduced ejection fraction (HFrEF), and patients with HF with preserved ejection fraction (HFpEF).
Methods: A total of 83 patients with HFrEF, 68 patients with HFpEF, and 84 control subjects were analyzed. All HF patients had a history of hospitalization for HF treatment. Brachial-ankle pulse wave velocity (baPWV) measurement and transthoracic echocardiography were performed at the same day in a stable condition.
Results: The baPWV was significantly higher in patients with both HFrEF and HFpEF compared to control subjects (1,661 ± 390, 1,909 ± 466, and 1,477 ± 296 cm/sec, respectively; P < 0.05 for each). After adjustment of age, baPWV values were similar between patients with HFrEF and HFpEF (P = 0.948). In the multiple linear regression analysis, baPWV was significantly associated with both septal e' velocity (β = -0.360, P = 0.001) and E/e' (β = 0.344, P = 0.001). However, baPWV was not associated with either of the diastolic indices in HFrEF group. The baPWV was associated only with septal e' velocity (β = -0.429, P = 0.002) but not with E/e' in the HFpEF group in the same multivariable analysis.
Conclusions: Although arterial stiffness was increased, its association with LV diastolic function was attenuated in HF patients compared to control subjects. The degree of arterial stiffening was similar between HFrEF and HFpEF.

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.

Arterial stiffening is an independent risk factor for cardiovascular diseases, particularly affecting organs with low vascular resistance, such as the brain and kidneys. Pulse wave velocity (PWV) is the clinical gold standard for arterial stiffness assessment; however, conventional equipment requires complex setups and trained operators, limiting real-world and point-of-care monitoring. Here, we introduce a tactile-transparent wearable (TTW) sensor that preserves physicians' tactile pulse palpation abilities while providing quantitative cardiovascular risk assessment by integrating flexible Polydimethylsiloxane (PDMS) electrodes and ultrathin graphene oxide dielectric films.

Imaging photoplethysmography (iPPG) is an emerging optical technique that allows for the contactless acquisition of arterial Blood Volume Pulse (BVP) signals from video recordings of the human skin. While iPPG offers a non-contact and convenient means for physiological monitoring, the accuracy of the extracted BVP signals remains limited. This limitation hinders its potential for advanced cardiovascular assessments, such as evaluations of arterial stiffness and cardiac function.

Neutrophil extracellular traps (NETs)-web-like DNA structures extruded by neutrophils in response to various stimuli, including pathogens, sterile inflammation, and mechanical stress-play a dual role in immunity and disease. While NETs serve to trap and neutralize pathogens during host defense, excessive or dysregulated NET formation, known as NETosis, can amplify inflammation and contribute to thrombotic complications such as atherosclerosis and valve disease. Increasing evidence supports that NETosis is a regulated, signaling-driven process, and that mechanical forces-including shear stress, tensile force, and matrix stiffness-can act as noncanonical danger signals capable of inducing NETosis.

Background: Elevated pulse pressure (PP), indicative of arterial stiffness, has been implicated in cognitive impairment and Alzheimer's disease (AD) pathology. However, its role in preclinical AD and interactions with genetic risk factors like apolipoprotein E ε4 (APOE4) remain unclear.
Objectives: To investigate the association between baseline PP and AD biomarkers (amyloid-beta (Aβ) and tau) and cognitive decline, and to determine whether APOE4 carrier status moderates these relationships.
