Background: Arterial stiffness is a crucial factor in the pathogenesis of cardiovascular disease, often associated with aging. However, the impact of smoking on arterial stiffness is frequently underestimated. This study aims to investigate the intricate relationship between smoking and arterial stiffness to advance our understanding of and therapeutic approaches to cardiovascular health.
Methods: A prospective analysis was conducted from January to July 2024, focusing on arterial stiffness parameters in a cohort of students from the Carol Davila University of Medicine and Pharmacy. Participants were categorized as smokers or non-smokers based on self-reported smoking status. The study endpoints included correlations between high pulse wave velocity, elevated peripheral and central systolic blood pressure, increased peripheral and central pulse pressure, and smoking status. These markers were assessed using an arteriograph device measuring the time difference between the initial forward pulse wave and the reflected pulse wave in the brachial artery to indirectly estimate the PWV using oscillometric pulsations.
Results: Our investigation, involving 102 young individuals aged 20 to 26 (69 females, 33 males), revealed that smokers exhibited significantly higher average values of arterial stiffness indicators compared to non-smokers. Current smokers had higher mean systolic blood pressure (130.65 vs. 123.05 mmHg), higher mean peripheral pulse pressure (53.19 vs. 45.64 mmHg), higher mean central pulse pressure (33.66 vs. 29.69 mmHg), and higher mean pulse wave velocity (5.27 vs. 5.03 m/s).
Conclusions: The utilization of arterial stiffness markers as predictive tools offers opportunities for personalized treatment strategies, potentially enhancing cardiovascular health outcomes.

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.

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.
