Ankle-brachial index and brachial-ankle pulse wave velocity are associated with albuminuria in community-based Han Chinese

Background/objectives: Our study aimed to explore whether the ankle-brachial index (ABI) and brachial-ankle pulse wave velocity (baPWV) were associated with albuminuria in community-based Han Chinese. Methods: Total 2127 subjects (860 men and 1267 women) aged 60 years and over were recruited in Beijing. Albuminuria was assessed by the urinary albumin-to-creatinine ratio (UACR) of ≥30 mg/g. BaPWV was divided by quartile. The logistic regression was used to determine the odds ratio (OR) and 95% confidence intervals (CIs) of ABI and baPWV with albuminuria. Results: ABI was associated with albuminuria in the interaction model (OR 0.89, 95% CI 0.81–0.99 by every 0.1 unit increase of ABI), especially in hypertension (OR 0.82, 95% CI 0.73–0.92) and diabetes (OR 0.83, 95% CI 0.68–0.98) groups. BaPWV groups were also significantly associated with albuminuria, ORs of having albuminuria for baPWV quartile II, III, and IV were 1.02(0.65–1.52), 1.05(0.72–1.61), and 1.18(1.04–1.47) in the interaction model. For hypertension and diabetes patients, only the baPWV quartile IV group had higher OR. Conclusions: ABI and baPWV were associated with albuminuria after adjusting for other risk factors in Chinese community-based elderly Han population. The association of ABI with albuminuria was stronger in hypertension and diabetes patients.     

Associations of plasma homocysteine levels with arterial stiffness in prehypertensive individuals

Prehypertension is associated with oxidative stress and increased arterial stiffness. While plasma homocysteine levels are associated with increased pulse wave velocity in hypertensive individuals, there is no report regarding this relationship in prehypertensives. Homocysteine levels and brachial-ankle pulse wave velocity (baPWV) were investigated in 4177 prehypertensives (3178 men, mean age 53 ± 11 years) with ankle-brachial indexes (ABIs) greater than 0.95 who had visited the Kangbuk Samsung Health Promotion Center. The subjects were subdivided into two groups according to baPWV; group I (1720 subjects) was defined as subjects with a baPWV of 1366 cm/sec or lower, while group II (2457 subjects) included subjects with a baPWV greater than 1366 cm/sec. Subjects were also divided into four quartile groups depending on homocysteine level. Homocysteine levels in group II were found to be significantly higher than those in group I. There were significant differences in baPWV value among the four quartile groups (quartile I, 1411 ± 213.9 cm/sec; quartile II, 1436 ± 223.3 cm/sec; quartile III, 1460 ± 220.4 cm/sec; quartile IV, 1494 ± 251.3 cm/sec; p-value <0.001). In multivariate regression models, the increasing quartile groups of homocysteine had higher odds ratios (ORs) for increased baPWV compared to that of the lowest quartile group (OR [95% confidence interval (CI)] in the second, third, and highest quartiles: 1.41 [1.12-1.77], 1.65 [1.30-2.10], and 1.82 [1.42-2.33], respectively, p < 0.001), irrespective of confounding factors. This study indicates an independent relationship between circulating homocysteine level and arterial stiffness in prehypertensives, suggesting that circulating homocysteine level could be a useful biomarker of subclinical target organ damage in prehypertensives.     

The relationship of endothelial function and arterial stiffness with subclinical target organ damage in essential hypertension

This study aimed to explore whether brachial‐ankle pulse wave velocity (baPWV) and brachial artery flow‐mediated dilation (FMD) or the interaction of both parameters are associated with subclinical target organ damage (STOD) indices in patients with essential hypertension. A total of 4618 patients registered from January 2015 to October 2020 were included. baPWV and FMD were measured to evaluate arterial stiffness and endothelial dysfunction. Whereas left ventricular hypertrophy (LVH), urine albumin‐creatinine ratio (UACR), and carotid intima‐media thickness (CIMT) were obtained as STOD indicators. On multivariable logistic regression analysis with potential confounders, higher quartiles of baPWV and FMD were significantly associated with an increased risk of STOD. In patients <65 years of age, the odds ratio (OR) of LVH, UACR, and CIMT ≥.9 mm for the fourth versus the first quartile of baPWV were 1.765 (1.390–2.240), 2.832 (2.014–3.813), and 3.075 (2.315–4.084), respectively. In interaction analysis, an increase in baPWV shows a progressively higher risk of STOD across the quartiles of FMD. Also, the estimated absolute risks of LVH, UACR, and CIMT ≥.9 mm for the first to fourth quartile of baPWV increased from 1.88 to 2.75, 2.35 to 4.44, and 3.10 to 6.10, respectively, in patients grouped by FMD quartiles. The addition of baPWV to FMD slightly improved risk prediction for STOD. BaPWV and FMD were independently associated with an increased risk of STOD in patients with essential hypertension especially among patients <65 years of age. Patients with elevated baPWV and decreased FMD parameters are at increased risk of STOD.

Abstract：

Objective To study the correlation between hyperinsulinemia (HIns) and arteriosclerosis in one community in Beijing. Methods Subjects who received arteriosclerosis screening in physical examination annually were studied. All subjects were received 75g oral glucose tolerance test (OGTT) to evaluate glucose metabolic level, and brachial-ankle pulse wave velocity (baPWV) examination to evaluate arteriosclerosis. The correlation between hyperinsulinemia and pulse wave velocity was analyzed. Results Among all the 1046 subjects under investigation, baPWV of subjects with HIns was higher than subjects with normoinsulinemia (NIns) in different glucose metabolism status [normal glucose tolerance, ( 1381.2 ±280. 8) cm/s vs ( 1280. 3 ±218. 7) cm/s; imparied glucose regulation, ( 1557. 5 ±319.3) cm/s vs (1474.7 ±305. 1) cm/s; diabetes, (1764.3 ±476.6) cm/s vs (1664.2 ±374.6)cm/s], especially in subjects with normal glucose tolerance ( P ＜ 0.01 ). The prevalence of cardiovascular risk factors in subjects with HIns was much higher than subjects with NIns ( P ＜ 0.01 ). Multiple logistic regression analysis showed that hyperinsulinemia was the risk factor of arteriosclerosis, and the OR (95%CI) of subjects with HIns was 1.91 (1. 169-3. 105, P ＜0.01 ) as compared to the subjects with NIns. Conclusion The subjects with HIns suffered from much more metabolic risk factors than NIns.Hyperinsulinemia that closely correlated with baPWV was a risk factor of arteriosclerosis.

High triglyceride to high‐density lipoprotein cholesterol ratio and arterial stiffness in postmenopausal Korean women

The ratio of triglyceride to high‐density lipoprotein cholesterol (TG/HDL) is positively linked to insulin resistance, and it has emerged as an independent predictor of cardiovascular disease. Menopause is characterized by various detrimental metabolic and vascular changes that may lead to high TG with low HDL cholesterol and arterial stiffness. Several epidemiological studies have reported that high TG/HDL ratio has a positive association with arterial stiffness in both adult and adolescent populations; it is not known whether TG/HDL ratio is related to brachial‐ankle PWV (baPWV) in postmenopausal women. Thus, the authors aimed to investigate the association between TG/HDL ratio and arterial stiffness as measured by baPWV in 434 postmenopausal women. The odds ratios (ORs) and 95% confidence intervals (95% CIs) for high baPWV were calculated after adjusting for confounding variables across TG/HDL ratio quartiles using multiple logistic regression analysis. The mean values of meaningful cardiometabolic variables increased with TG/HDL ratio quartiles. The adjusted baPWV (SEs) significantly increased with TG/HDL quartiles: Q1 = 1412 (22.1), Q2 = 1469 (21.4), Q3 = 1482 (21.0), and Q4 = 1505 (21.6) cm/s after adjusting for age, body mass index (BMI), and systolic blood pressure. The OR (95% CI) of the highest TG/HDL ratio quartile as compared to the lowest TG/HDL ratio quartile for high PWV was 2.77 (1.16‐6.63) after adjusting for age, BMI, smoking status, regular exercise, mean arterial pressure, fasting plasma glucose, total cholesterol level, hypertension, log‐transformed C‐reactive protein, and the use of antihypertensive and lipid‐lowering drugs. The TG/HDL ratio was positively and independently associated with arterial stiffness in postmenopausal Korean women.
