Advanced endothelial dysfunction in diabetic patients with multiple risk factors; importance of insulin resistance

AIM: Endothelial dysfunction is considered an early event in the development of atherosclerosis. The present study was undertaken to determine whether the accumulation of cardiovascular risk factors and insulin resistance are associated with endothelial function in diabetic patients.METHODS: 101 patients with type 2 diabetes without macroangiopathy stratified by the number of cardiovascular risk factors (dyslipidemia, hypertension, obesity) and 9 normal control subjects were studied for vascular endothelial functions by measuring flow-mediated vasodilation (FMD) using a high-resolution ultrasound method, brachial-ankle pulse wave velocity (baPWV), carotid intima-media thickness (IMT), and the ankle-brachial index (ABI).RESULTS: FMD negatively correlated with baPWV and carotid IMT, and positively correlated with ABI. FMD was significantly lower in diabetic patients associated with 3 other risk factors than in those with diabetes alone. In subjects with fasting plasma glucose < or = 140mg/dL, FMD showed significant negative correlations with fasting insulin levels and homeostasis model assessment (HOMA)-R. Multivariate analysis revealed that insulin resistance as represented by HOMA-R and systolic blood pressure showed a significant association with impaired FMD.CONCLUSION: The present results suggest that the accumulation of cardiovascular risk factors is associated with endothelial dysfunction in diabetic patients, and that insulin resistance as well as high blood pressure could play a pathogenic role in the development of endothelial dysfunction.     

The relationship between flow-mediated dilatation and left ventricular function in type 2 diabetic patients with microalbuminuria

Objective The aim of this study was to assess the relationship between flow-mediated dilatation (FMD) and left ventricular (LV) systolic and diastolic function in type 2 diabetic patients with or without microalbuminuria. Research Design and Methods We prospectively evaluated 68 consecutive patients (36 women, 32 men; mean age 57±11 yr) with type 2 diabetes mellitus (DM). Patients were divided into two groups according to whether or not they had microalbuminuria: group 1 (n=29, mean age 58±10 yr) with microalbuminuria and group 2 (n=39, mean age 56±10 yr) without microalbuminuria. LV function was assessed by classical methods and Doppler tissue imaging (DTI). Left ventricular ejection fraction (EF), interventricular (IVS) and posterior wall (PW) thickness, peak early (E) and late (A) transmitral filling velocities, their ratio (E/A) and deceleration time of the mitral E wave (DT), LV isovolumetric relaxation time (IVRT), flow propagation of velocity (Vp), and E/Vp were evaluated by conventional echocardiography. Early diastolic (Em), late diastolic (Am), and peak systolic (Sm) mitral annular velocities were measured. Em/Am and the ratio of early diastolic mitral inflow velocity to Em (E/Em), which is a reasonably good index for predicting elevated LV filling pressure, were calculated by DTI. Endothelial function, measured as flow-mediated dilatation of the brachial artery using ultrasound, was calculated in two groups. Results FMD was lower in those with microalbuminuria than those without (8.8±6.44% vs 12.6±7.24%, p=0.03). Group 1 had longer DT (223±39 ms vs 199±37 ms, p=0.01) and longer IVRT (109±13 ms vs 100 ±13 ms, p=0.03) than that of group 2 with conventional echocardiography. Group 1 had significantly lower Em/Am (0.79±0.27 cm/s vs 1.02±0.44 cm/s, p=0.01), lower Vp (40.4±9.98 vs 50.4±19.01 cm/s, p=0.01) than that of group 2. Group 1 had significantly higher serum creatinine (1±0.33 mg/dL vs 0.7±0.19, p=0.001). In logistic regression analysis, FMD was the only variable independently related to microalbuminuria. FMD was positively correlated with EF (r=0.43, p=0.02) and E/A (r=0.40, p=0.03), and negatively correlated with E/Em (r=0.41, p=0.04) and E/Vp (r=0.41), p=0.04) only in patients with microalbuminuria. Conclusion It was found that left ventricular diastolic function and FMD are impaired in type 2 diabetic patients with microalbuminuria. FMD may be related to LV diastolic dysfunction only in patients with microalbuminuria.

Correlation between arterial stiffness and coronary flow velocity reserve in subjects with pulse wave velocity >1400 cm/s

Brachial-ankle pulse wave velocity (ba-PWV) is an independent predictor for cardiovascular events. Coronary flow velocity reserve (CFVR) provides important information for coronary endothelial function. In the present study, we investigated the possible relationship between PWV and CFVR, especially in subjects with PWV?>?1400?cm/s. Seventy five subjects were divided into two groups based on baPWV value (baPWV?>?1400?cm/s versus baPWV?<?1400?cm/s). PWV and CFVR were measured by Colin VP-1000 apparatus and non-invasive Doppler echocardiography, respectively. Our results showed that CFVR was significantly lower in patients with baPWV?>?1400?cm/s than in patients with baPWV?<?1400?cm/s (2.57?±?0.68 versus 3.04?±?0.73, p?<?0.01). baPWV was negatively correlated with CFVR in the entire study group (r?=??0.45, p?<?0.0001) even adjusting for age, prevalence of diabetes mellitus and systolic blood pressure (r?=??0.33, p?=?0.044). Moreover, baPWV was markedly negatively correlated with CFVR in patients with baPWV?>?1400?cm/s (r?=??0.42, p?<?0.01). Multiple linear regressions showed that baPWV was independently associated with CFVR in the entire study group (β?=??0.702, p?<?0.001). Our results showed that large arterial stiffness was negatively correlated with decreased CFVR especially in subjects with baPWV?>?1400?cm/s, and baPWV was independently associated with CFVR.     

Pulse wave velocity as an indicator of atherosclerosis in obstructive sleep apnea syndrome patients

OBJECTIVE: Obstructive sleep apnea syndrome (OSAS) is associated with increased cardiovascular morbidity and mortality. We investigated the values of brachial-ankle pulse wave velocity as an indicator of atherosclerosis in obstructive sleep apnea syndrome patients. MATERIALS AND METHODS: Brachial-ankle pulse wave velocity (baPWV) was measured in 104 OSAS patients and 104 healthy control subjects matched for age, sex, and body mass index (BMI). BaPWV values were compared in both groups and investigated with respect to the number of risk factors for atherosclerosis, including hypertension, hypercholesterolemia, impaired glucose tolerance, smoking, and obesity. Comparisons were also made between 48 OSAS group cases and 90 control group cases free from hypertension, which has a major impact on baPWV. RESULTS: As compared to the control group, the OSAS group had significantly higher baPWV (1,645+/-349 cm/s vs 1,436+/-278 cm/s, p<0.0001), and values obtained for baPWV were significantly higher in the OSAS group than in the control group even in groups free from hypertension (1,453+/-216 cm/s vs 1,374+/-213 cm/s, p<0.05). In both groups, baPWV rose as the number of risk factors for atherosclerosis increased, but baPWV was higher in the OSAS group than in the control group even in a comparison of individuals entirely free from risk factors (1,400+/-200 cm/s vs 1,198+/-79 cm/s, p<0.05). CONCLUSION: The condition of OSAS itself is considered a possible risk factor for atherosclerosis. We believe that the usefulness of baPWV as an index of atherosclerosis merits further study in the frequently observed cases of OSAS complicated by cardiovascular disease.     

Improvement in Brachial Endothelial Vasomotor Function and Brachial-Ankle Pulse Wave Velocity Reduces the Residual Risk for Cardiovascular Events after Optimal Medical Treatment in Patients with Coronary Artery Disease

Aim: To examine whether improvement in flow-mediated endothelium-dependent dilatation (FMD) of the brachial artery and brachial-ankle pulse wave velocity (baPWV) has an additive effect on achieving optimal goals of traditional risk factors to reduce cardiovascular risk in patients with coronary artery disease (CAD). Methods: We assessed 323 patients with CAD and impaired vascular function, defined as an impaired FMD of the brachial artery (＜5.5%) and increased baPWV (＞1,440 cm/sec). After FMD and baPWV measurements at 24 weeks of optimal medical treatment (OMT), the study patients were followed up for ＜60 months or until a composite of cardiac death, nonfatal myocardial infarction (MI), unstable angina, or ischemic stroke occurs. Results: During the median follow-up period of 35 months, cardiovascular events occurred in 72 patients. Multivariate Cox hazards analysis showed that patients with an improvement in FMD and baPWV had the lowest probability of future cardiovascular events. In addition, the improvement in FMD and baPWV had a significant incremental effect on the predictive value of the achievement of optimal goals for blood pressure (BP), low-density lipoprotein cholesterol (LDL-C), and hemoglobin A1c (HbA1c) using net reclassification improvement (NRI) and integrated discrimination improvement (IDI). Conclusions: The improvement in FMD and baPWV had additive effects on risk reduction of the achievement of the optimal goals of traditional risk factors in patients with CAD. Thus, serial measurements of FMD and baPWV may be useful for identifying CAD patients at residual risk for adverse cardiovascular events following OMT.     

Bone Mineral Density Is Negatively Associated With Arterial Stiffness in Men With Hypertension

Hypertension (HTN) and osteoporosis are associated with the development and progress of atherosclerosis. However, little research has been conducted to examine the relationship between arterial stiffness and bone mineral density (BMD) in men with HTN. This cross‐sectional study recruited 355 men with HTN and 353 control patients without HTN. Brachial‐ankle pulse wave velocity (baPWV) and BMD measurements were performed. BMD was decreased and baPWV was elevated in patients with HTN compared with control patients (femoral neck [FN] BMD in the HTN and control groups were 0.662±0.195 g/cm² and 0.713±0.204 g/cm², respectively [P=.001], and baPWV in the HTN and control groups were 1403.3±156.8 cm/s and 1354.8±136.0 cm/s, respectively [P<.001]). Multiple linear regression analysis demonstrated that FN BMD was negatively associated with increased baPWV in HTN. Reduced FN BMD may be an independent factor for baPWV in patients with HTN.

Efficacy of γ-linolenic acid,Vitis vinifera extract,and acetyl-L-carnitine combination therapy for improving arterial stiffness in Korean adults: Real-world evidence

Atherosclerosis is associated with various cardiovascular diseases (CVDs). Measurement of arterial stiffness using pulse wave velocity (PWV) enables assessment of atherosclerosis progression in individuals. The authors screened patients with asymptomatic atherosclerosis, based on the PWV findings, to evaluate appropriate early interventions and assess the efficacy of γ-linolenic acid, Vitis vinifera extract, and acetyl-L-carnitine triple combination therapy in atherosclerosis prevention. This retrospective study analyzed the medical records of adult patients between March 2007 and April 2019, with presenting complaints of fatigue and lethargy. Among patients with vascular stiffness beyond their biological age on brachial-ankle PWV (baPWV) testing, those with ≥80% compliance for three drugs were allocated to the experimental group. Those with compliance of <80% for any one drug were allocated to the control group to assess changes in arterial stiffness, fasting plasma glucose (FPG), lipid level, and blood pressure (BP). After 1 year of triple-combination therapy, there were significant decreases in right and left baPWV (1537.16 ± 274.84 and 1519.00 ± 289.32 cm/s, respectively) as compared to baseline (1633.15 ± 271. 20 and 1598.64 ± 267.95 cm/s, respectively; p < .001). There was no difference in baPWV between sexes. Moreover, neither group showed significant changes in FPG and lipid levels. When triple-combination therapy combining γ-linolenic acid, V. vinifera extract, and acetyl-L-carnitine was administered to patients with high arterial stiffness relative to their age, as assessed by baPWV, the experimental group showed a decrease in arterial stiffness in both sexes.     

Brachial-ankle pulse wave velocity is an independent predictor of carotid artery atherosclerosis in the elderly

Objective Brachial-ankle pulse wave velocity （baPWV） is widely used as a simple noninvasive measure of arterial softness. The aim of this study was to evaluate the usefulness of baPWV as a predictor of the carotid artery atherosclerosis in the elderly. Methods A total of 721 elderly participants （mean ~ SD age, 70.3 -4- 5.6years） were enrolled in the current study. All participant underwent both baPWV measurement and B-mode ultrasound for the intima-media thickness. Carotid atherosclerosis （CAS） was defined as the present of carotid plaque or and/or intima media thickness for at least 1.1 mm. Results A multivariate logistic regression analysis reveals that age, sex, brachial-ankle pulse wave velocity, smoking and LDL-C level showed a significant correlation with the presence of CAS. The odds ratios of CAS associated with a 500cm/s increase of brachial-ankle pulse wave velocity were 2.378 [95% confidence interval, 1.36 to 4.00, P〈0.05], 3.733 [95% confidence interval, 1.729 to 8.058, P〈0.01], 4.438 [95% confidence interval, 1.659 to 11.803, P〈0.01]. The baPWV significantly correlated with IMT by bivariate correlation analysis （r=-0.39; p=0.001）. After adjusting for factors influencing, baPWV all the same correlated with IMT （r=-0.35; p=0.001）.Conclusion These results indicate that brachial-ankle PWV is an independent predictor of CAS in the elderly.It also means that the direct measurement of arterial stiffness by this simple method may be of great help for the evaluation of carotid artherosclerosis, at least in the elderly
