AI Article Synopsis

  • The study investigates the link between educational levels and arterial stiffness in Japanese men and women, focusing on data over a five-year period.
  • Among the 1381 participants, results showed no significant difference in baseline arterial stiffness based on education, but older women (≥ 65 years) with higher education had less increase in arterial stiffness over five years.
  • The findings suggest that education may influence arterial stiffness differently based on age and sex, particularly highlighting its impact on older women.

Article Abstract

Aim: Previous studies have shown that higher educational levels are associated with slower progression of arterial stiffness; however, evidence from Asian countries is lacking. We aimed to examine the association between educational level and arterial stiffness measured using the cardio-ankle vascular index (CAVI) over time in a sample of Japanese men and women.

Methods: A total of 1381 participants (453 men and 928 women) were included in the present study. Arterial stiffness was measured using the CAVI at baseline (2009-2012) and 5 years later (2014-2018). The educational level was divided into two groups (junior or senior high school vs. junior college, professional school, college, or higher) based on a self-administered questionnaire. A mixed-effects model was used to analyze the association between education and the CAVI at baseline and its change over 5 years. The participants were stratified by sex and age (<65 vs. ≥ 65 years).

Results: The CAVI at baseline did not differ significantly according to education in any of the four subgroups accorded to age and sex. However, among women of ≥ 65 years of age, the change in the CAVI over 5 years was significantly smaller in the higher education group (p=0.04). No such association was found in women of <65 years of age or men.

Conclusions: Education is a factor that affects arterial stiffness in women of ≥ 65 years of age. These results suggest that educational level affects arterial stiffness, depending on sex and age.

Impact of SGLT2 Inhibitors on Lipoproteins in Type 2 Diabetes.

Purpose Of Review: This article explores the cardiovascular effects of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in patients with type 2 diabetes mellitus (T2DM), with a particular focus on their impact on lipid profiles. As evidence grows of the cardiovascular benefits of SGLT2i beyond glucose control, it is essential to better understand their effects on lipoproteins and their impact on cardiovascular disease.

Recent Findings: SGLT2i have shown significant cardiovascular benefits in patients with type 2 diabetes mellitus, beyond their role in lowering blood glucose.

Deep Learning Analysis of White Matter Hyperintensity and its Association with Comprehensive Vascular Factors in Two Large General Populations.

Although the relationships between basic clinical parameters and white matter hyperintensity (WMH) have been studied, the associations between vascular factors and WMH volume in general populations remain unclear. We investigated the associations between clinical parameters including comprehensive vascular factors and WMH in two large general populations. This retrospective, cross-sectional study involved two populations: individuals who underwent general health examinations at the Asan Medical Center (AMC) and participants from a regional cohort, the Korean Genome and Epidemiology Study (KoGES).

Runx2-NLRP3 Axis Orchestrates Matrix Stiffness-evoked Vascular Smooth Muscle Cell Inflammation.

Arterial stiffening is a hallmark of chronic kidney disease (CKD) related cardiovascular events and is primarily attributed to the elevated matrix stiffness. Stiffened arteries are accompanied by low-grade inflammation, but the causal effects of matrix stiffness on inflammation remain unknown. For analysis of the relationship between arterial stiffness and vascular inflammation, pulse wave velocity (PWV) and aortic inflammatory markers were analyzed in an adenine-induced mouse model of CKD in chronological order.

Although often overlooked sleep apnea has emerged as a significant public health concern. Obstructive sleep apnea (OSA) and diabetes commonly co-exist with a vicious cycle worsening the incidence and severity of both conditions. OSA has many implications including cardiometabolic disorders and impaired cardiovascular (CV) prognosis.

Chicken essence (CE) is known for its antihypertensive properties. However, few studies have investigated the effects of CE in prehypertensive individuals. Here, we conducted a randomized crossover clinical trial on prehypertensive offspring of hypertensive parents to evaluate the effects of preworkout CE consumption (CEC) on post-exercise hypotension (PEH) and cardiac autonomic and vascular responses.
