Article Synopsis
- * The research included over 13,000 participants from Japan who underwent annual health check-ups, using machine learning techniques to analyze their data and predict AF risk, with 80% of the data training the model and 20% testing its accuracy.
- * The model's performance showed a promising accuracy score, with age being the most significant risk factor for developing new-onset AF, along with other health indicators such as body mass index and blood pressure, potentially aiding in the early
Hyperuricemia is associated with kidney function decline (KFD), although whether hyperuricemia directly causes nephrotoxicity or is indirectly mediated by systemic arterial stiffening remains unclear. We examined the detailed relationship of serum uric acid (SUA) with KFD and potential mediation by arterial stiffness. Study population was 27,648 urban residents with an estimated glomerular filtration rate (eGFR) of ≥60 mL/min/1.

We aimed to determine the detailed relationship of baseline lipid parameters with KFD, considering the mediation of arterial stiffness.
Methods: A total of 27 864 urban residents with estimated glomerular filtration rate (eGFR) ≥60 mL/min/1.
Aim: To elucidate the mechanism by which cigarette smoking causes vascular damage, we examined the relationship between cumulative cigarette consumption and abdominal obesity, and the possible mediating effect of smoking on arterial stiffness.
Methods: Cross-sectional data from 19499 never smokers and 5406 current smokers receiving health screening was analyzed. Abdominal obesity was assessed by ABSI, and arterial stiffness by CAVI.
A body shape index (ABSI) is an abdominal obesity index developed based on epidemiological statistics and designed to correlate minimally with body mass index (BMI). We examined the approximation between ABSI and other abdominal obesity indices based on biophysical concepts. The cross-sectional data from 62,514 Japanese urban residents were analyzed.

This arterial stiffness parameter is useful for assessing the severity of cardiovascular disease (CVD) and its risk. However, compared to pulse wave velocity (PWV), the conventional gold standard of arterial stiffness parameter, there has been a concern regarding CAVI that there are fewer longitudinal studies for CVD.

This study aimed to compare the predictive ability of three arterial stiffness parameters at baseline; cardio-ankle vascular index (CAVI), heart-ankle pulse wave velocity (haPWV) and CAVI 0 , a variant of CAVI that theoretically excludes dependence on blood pressure, for renal function decline in Japanese general population.
Methods: A total of 27 864 Japanese urban residents without renal impairment at baseline who participated in two to eight consecutive (mean 3.
Aim: Physiological tests to assess systemic vascular function are not included in the risk score for atrial fibrillation (AF). We aimed to examine whether cardio-ankle vascular index (CAVI), a systemic arterial stiffness parameter, is associated with the presence of AF in Japanese general population.
Methods: A cross-sectional study (N = 47,687) and a cohort study (N = 5418, four consecutive years) in Japanese urban residents who participated in annual health screening were conducted.
Introduction: Abdominal obesity as a risk factor for diagnosing metabolic syndrome (MetS) is evaluated using waist circumference (WC), although WC does not necessarily reflect visceral adiposity. This cross-sectional study aimed to clarify whether replacing WC with "A Body Shape Index (ABSI)," an abdominal obesity index, in MetS diagnosis detects individuals with arterial stiffening assessed by cardio-ankle vascular index (CAVI).
Methods: A retrospective cross-sectional study was conducted in 46,872 Japanese urban residents (median age 40 years) who underwent health screening.
Background: Abdominal obesity as a risk factor for diagnosing metabolic syndrome (MetS) is conventionally evaluated using waist circumference (WC), although WC does not necessarily reflect visceral adiposity.
Objective: To examine whether replacing WC with "A Body Shape Index (ABSI)", an abdominal obesity index calculated by dividing WC by an allometric regression of weight and height, in MetS diagnosis is useful for predicting renal function decline.
Subjects/methods: In total, 5438 Japanese urban residents (median age 48 years) who participated in a public health screening program for 4 consecutive years were enrolled.
Increased intima-media thickness and plaque development in the extracranial carotid arteries reportedly correlate well with the prevalence of coronary artery diseases. The location of these atherosclerotic lesions in the carotid artery varies with age in patients with coronary artery atherosclerosis. Intima-media thickness, plaque, and calcification in the common carotid artery and bifurcation were assessed with high-resolution B-mode ultrasonography.
