The Relationship

Abstract Background To investigate the difference of carotid structural abnormality and stiffness, and the relationship between carotid structural abnormality and stiffness in prehypertensive and normotensive subjects. Methods A total of 581 participants (270 with prehypertension, 311 normotensive control subjects) from the First Affiliated Hospital of Fujian Medical University were enrolled from January 2017 to March 2019. Body height/weight, resting heart rate, and blood pressure were recorded. Blood biochemical indexes and carotid–femoral pulse wave velocity were determined, and carotid ultrasonography was performed. Carotid intima–media thickness ≥1.0 mm and carotid–femoral pulse wave velocity ≥10.0 m/s were defined as carotid structural abnormality and arterial stiffness, respectively. Results The percentage of patients with carotid structural abnormality (60.7% vs. 51.4%), carotid–femoral pulse wave velocity [(8.78 ± 1.48) vs. (7.92 ± 1.30) m/s], and the percentage of patients with arterial stiffness (13.7% vs. 5.8%) were increased in the prehypertension group compared with the control group (all P < 0.05). In the prehypertension group, the percentage of patients with arterial stiffness in the abnormal carotid structure subgroup (n = 164) was higher than that in the normal carotid structure subgroup (n = 106) (20.1% vs. 3.8%, χ2 = 14.551, P < 0.001). Furthermore, carotid structural abnormality, age, diabetes mellitus, resting heart rate, systolic blood pressure, fasting blood glucose, glycosylated hemoglobin A1c, and hypoglycemic therapy were all correlated with arterial stiffness (all P < 0.05). After adjusting for other cardiovascular risk factors, multiple logistic regression analysis showed that carotid structural abnormality, age, diabetes mellitus, and resting heart rate were independently correlated with arterial stiffness, and patients with carotid structural abnormality had 5.25-fold higher risk of arterial stiffness than those with a normal carotid arterial structure (odds ratio = 5.250, 95% confidence interval 1.580–17.448, P = 0.007). However, in the normotensive group, no such relationships were observed between carotid artery structural abnormality and stiffness. Conclusions In prehypertensives but not normotensives, carotid artery structural abnormalities and stiffness are common, and independently correlated.

The Relationship

Background increased arterial stiffness is a predictor of cardiovascular events. The stroke volume (SV) to pulse pressure (PP) ratio is an estimate of arterial capacitance. Pulse wave velocity (PWV) is a measure of arterial stiffness. This study evaluated the effect of left ventricular (LV) SV on the SV/PP–PWV relationship. Methods 97 patients had applanation tonometry and echocardiography to measure arterial capacitance (SV/PP), PWV, and central aortic pressure. Results 50 patients had normal SV and 47 had low SV. For all patients, PWV inversely correlated with SV/PP. PWV and SV/PP correlated more strongly in the normal SV group than in the low SV group. Aortic PP was significantly correlated with PWV in all patients, in the normal SV group, and in the low SV group. Conclusion effective arterial capacitance correlates with PWV. The presence of decreased SV weakens the relationship.

The Relationship

Abstract Background: Association of arterial stiffness and osteoporosis has been investigated in Chinese population. However, the relationship between arterial stiffness and osteoporosis by measuring brachial-ankle pulse wave velocity (baPWV) and the Osteoporosis Self‐assessment Tool for Asia (OSTA) index is not established. The object of this study was to evaluate possible associations between baPWV and the risk of osteoporosis and bone fracture among a population of Chinese. Whether baPWV can be used as a predictor of osteoporosis on OSTA was further assessed. Methods: This study was cross-sectional in design. Of 3,984 adults aged 40 years and older in the Yunyan district of Guiyang (Guizhou, China) who underwent both OSTA and baPWV measurements within one month , 1,407 were deemed eligible for inclusion (women: 1,088, men: 319) . Results: The mean baPWV was 1,475 ± 302 cm/s (range,766-3,459cm/s). baPWV in 110 individuals with high risk of osteoporosis (OSTA index < -4) was higher than that of individuals with non-high risk (1,733 ± 461 cm/s versus 1,447 ± 304 cm/s, P<0.001). OSTA index was negatively correlated with baPWV（ρ = -0.296，P < 0.001）after adjusting for age, sex, body mass index, waist circumference, diastolic blood pressure and creatinine clearance rate. baPWV was an independent predictor for the presence of high risk of osteoporosis (β = -0.001, P < 0.001) and the optimal baPWV cut-off value for predicting the presence of high risk of osteoporosis and fracture was 1,693 cm/s. The AUC was 0.722 (95% confidence interval [CI], 0.667‐0.777; P < 0.001). Conclusions: We conclude that arterial stiffness measured by baPWV is well correlated with the severity of osteoporosis evaluated by OSTA. baPWV index may be a valuable tool for identifying individuals with risk of developing osteoporosis.

Abstract Introduction: Increasing arterial stiffness is a feature of vascular aging that is accelerated by conditions that enhance cardiovascular risk, including diabetes mellitus. Multiple studies demonstrate divergence of carotid-femoral pulse wave velocity and augmentation index in persons with diabetes mellitus, though mechanisms responsible for this are unclear.Materials and Methods: We tested the effect of acutely and independently increasing plasma glucose, plasma insulin, or both on hemodynamic function and markers of arterial stiffness (including carotid-femoral pulse wave velocity, augmentation index, forward and backward wave reflection amplitude, and wave reflection magnitude) in a four-arm, randomized study of healthy young adults.Results: Carotid-femoral pulse wave velocity increased only during hyperglycemic-hyperinsulinemia (+0.36 m/s; p=0.032), while other markers of arterial stiffness did not change (all p>0.05). Heart rate (+3.62 bpm; p=0.009), mean arterial pressure (+4.14 mmHg; p=0.033), central diastolic blood pressure (+4.16 mmHg; p=0.038), and peripheral diastolic blood pressure (+4.09 mmHg; p=0.044) also significantly increased during hyperglycemic-hyperinsulinemia.Conclusions: We conclude that the acute combination of moderate hyperglycemia and hyperinsulinemia preferentially stiffens central elastic arteries. This effect may be due to increased sympathetic activity. (ClinicalTrials.gov number NCT03520569; registered 9 May 2018).

G894t Polymorphism

Metabolic syndrome (MS) is a clustering entity characterized by obesity, hypertension, hyperglycemia, dyslipidemia, and insulin resistance. Atherosclerotic lesions may be a complication of MS, arising from endothelial dysfunction and induced by decreased nitric oxide (NO) production. NO is synthesized by nitric oxide synthase (eNOS), encoded by the NOS3 gene, and displays anti-inflammatory, vasodilatory, and antiproliferative effects.We aimed to investigate the relationship between the G894T polymorphism of the eNOS gene and metabolic syndrome (including its components) and the association of this polymorphism with arterial function, assessed by determining pulse wave velocity and the augmentation index.The study included 100 consecutive patients, 55% with metabolic syndrome (based on IDF criteria -study group), 45% without MS (control group). Arterial stiffness was measured using TensioMedTMArteriograph. The presence of the homozygous (TT) or heterozygous (GT) state was associated, compared to subjects without the mutation (GG), with an increased prevalence of arterial hypertension, diabetes mellitus, with an increase of abdominal circumference, an increase of triglycerides, without significantly influencing the level of HDL. No significant differences were found between patients with G894T polymorphism compared to those without the mutation regarding the arterial stiffness. The eNOS gene polymorphism: 894G]T was significantly associated with the presence of MS; the polymorphism in homozygous and heterozygous state was associated with an increased risk of metabolic syndrome. G894T polymorphism did not significantly influence the values of the studied arterial parameters (pulse wave velocity, aortic and brachial augmentation index).

Introduction: Large-artery stiffness is an independent predictor of hypertension which is a leading cause of excess cardiovascular morbidity and mortality. Carotid-femoral pulse wave velocity (cf-PWV) is considered the ‘gold-standard’ measure of arterial stiffness because it measures along the aorto-iliac pathway, which makes the largest contribution to the arterial buffering function. While there is well-documented evidence on the health benefits of aerobic and resistance exercise, the information for the effect of stretching on arterial stiffness is limited. Previous studies have shown that arterial stiffness is associated with trunk flexibility. Stretching exercise targeted to improve flexibility may exert a beneficial effect on reducing arterial stiffness. Purpose: This study aimed (1) to determine the association between trunk flexibility and arterial stiffness and (2) to examine whether one bout of stretching exercise will increase trunk flexibility and decrease arterial stiffness. Methods: Thirty healthy women (mean age = 44.37 years) were instructed to follow a 20-minute DVD demonstration of whole-body stretching. Before and after stretching, cf-PWV and trunk flexibility were measured by using the SphygmoCor system and by sit-and-reach test, respectively, as well as systolic and diastolic blood pressure (SBP and DBP) and heart rate (HR) by using a Welch Allyn Monitor. All data were measured after taking a 10-minute rest in a supine position. Results: cf-PWV was not related to trunk flexibility, however, cf-PWV was significantly decreased after stretching compared with before stretching (mean difference [MD]=.63, , p=.01). Trunk flexibility was also significantly increased after stretching (MD=-3.08, p=.00). Furthermore, while SBP and DBP did not change significantly, HR was significantly reduced after stretching compared with before stretching (MD=3.12, p=.00). Conclusions: Our results showed that one bout of stretching exercise had significant effects on reducing arterial stiffness and heart rate. Further testing of long-term effects of stretching exercise is warranted for development of preventative interventions to reduce arterial stiffness, an important subclinical biomarker of cardiovascular disease.

Dickkopf 1

Background: Sclerostin and Dickkopf-1 are extracellular inhibitors of the canonical Wnt/β-catenin signalling pathway, which is implicated in the development of arterial stiffness. However, the correlation between aortic stiffness and sclerostin or Dickkopf-1 levels in patients with type 2 diabetes mellitus is unknown. Methods: Fasting blood samples were collected from 125 patients with type 2 diabetes mellitus. Aortic stiffness was measured by carotid–femoral pulse wave velocity, and high aortic stiffness was defined by a carotid–femoral pulse wave velocity of >10 m/s. The serum sclerostin and Dickkopf-1 concentrations were determined using commercially available enzyme-linked immunosorbent assays. Results: In total, 46 patients with type 2 diabetes mellitus (36.8%) had high levels of aortic stiffness. Compared to the control group without aortic stiffness, this group was significantly older, had higher systolic and diastolic blood pressures, had higher blood urea nitrogen, creatinine, urinary albumin-to-creatinine ratio and serum sclerostin levels, and had significantly lower high-density lipoprotein cholesterol levels and estimated glomerular filtration rates. After adjusting for confounders, serum sclerostin [odds ratio = 1.005 (1.002–1.007), p = 0.002] levels remained an independent predictor of aortic stiffness. Multivariate analysis showed that the serum sclerostin level ( β = 0.374, adjusted R2 change = 0.221, p < 0.001) was positively associated with carotid–femoral pulse wave velocity. Conclusion: Serum levels of sclerostin, but not Dickkopf-1, are positively correlated with carotid–femoral pulse wave velocity and independently predict aortic stiffness in patients with type 2 diabetes mellitus.
