AimsTo assess whether the anthropometric index used by the American Heart Association (AHA) to evaluate cardiovascular health (CVH) status, i.e., the body mass index (BMI), could also be of value in ethnic groups phenotypically different than Whites.MethodsCVH status was evaluated in 616 Ecuadorian natives/mestizos aged ≥40 years with the seven metrics proposed by the AHA. Then, the BMI was replaced by the waist-to-hip (WtoHp) and the waist-to-height (WtoHt) ratios to estimate whether these changes modify the CVH status and the presence of ≥5 ideal metrics per person.ResultsReplacing the BMI for either the WtoHt or the WtoHp ratios reduces the percentage of persons with ≥5 ideal CVH metrics from 13%, to 8% (p < 0.004) and to 6.8% (p < 0.0003), respectively. The number of persons with a poor CVH status increased when the WtoHt ratio was used instead of the BMI (81.5% versus 69.8%, p < 0.0001).ConclusionsThese results may explain the paradox “better CVH status/similar stroke prevalence” previously found in Ecuadorian natives/mestizos, and suggest that the WtoHt ratio could be the best anthropometric index to be included in the set of metrics used to evaluate the CVH status in populations that are phenotypically different than Whites. 相似文献

ABSTRACTBackground: There is a well-established relationship between cardiorespiratory fitness (CRF) and arterial stiffness. However, it is unclear whether this relationship differs significantly between hypertensive and non-hypertensive patients.Methods: Adults without a history of ischemic heart disease or stroke and normal exercise test results who underwent health screening were included. Cardiopulmonary function test was performed using the Bruce protocol. Peak oxygen consumption (VO2peak) was measured. Arterial stiffness was evaluated using the brachial-ankle pulse wave velocity (baPWV).Results: Study subjects were 9232 participants (M:F = 71:29%) with a mean age of 53 ± 6 years. Thirty-four percent had hypertension. There was an inverse relationship between the peak oxygen consumption and baPWV (r = - 0.21, p < 0.001) This relationship persisted after adjusting for age, gender, body mass index, smoking, diabetes mellitus, hemoglobin A1c, LDL-cholesterol, mean blood pressure, and hypertension (p < 0.0001). The regression coefficient of VO2peak was significantly more negative among hypertensive subjects than it was in non-hypertensive subjects in the regression coefficient (?9.2 vs. ?4.2, p for interaction <0.001). The difference in arterial stiffness between hypertensive and non-hypertensive groups decreased as the CRF increased.Conclusion: Arterial stiffness decreased as CRF increased among participants without overt cardiovascular disease. The effect of hypertension on arterial stiffness also decreased as the CRF increased. 相似文献

BackgroundThe visceral adiposity index (VAI) is a new marker of adipose dysfunction and related with cardiometabolic risk. The aim of this study is to investigate the association of VAI with arterial stiffness in elderly Chinese population.MethodsA total of 1,707 elderly individuals over 60 years of age were recruited for this cross-sectional study. We measured body composition, anthropometrics, blood pressure, and lipid parameters. The arterial stiffness was measured by brachial-ankle pulse wave velocity (baPWV) and defined as baPWV ≥ 1400 cm/s. VAI? was calculated based on body mass index, waist circumference, triglyceride and high-density lipoprotein cholesterol. Multivariable regression analysis was performed to evaluate the association between VAI and baPWV.ResultsThere were significant differences in VAI tertiles between low-baPWV and high-baPWV group (p = 0.008). Univariate analysis demonstrated that age, history of hypertension, SBP, DBP, total cholesterol, fasting glucose, the higher VAI tertiles were correlated with the existence of high-baPWV (p < 0.05). Participants in the higher VAI tertiles had higher OR (1.0 ≤ VAI < 1.74: OR= 2.89, 95% CI [1.44, 5.80]; VAI ≥ 1.75: OR = 4.23, 95% CI [1.45, 12.37], p for trend: 0.004) comparing with the lowest VAI tertile. Non-linear relationship was detected between VAI and baPWV. VAI was positively correlated with baPWV when VAI < 2.10.ConclusionsThis study demonstrates that VAI is independently associated with the risk of arterial stiffness in elderly population. 相似文献

BackgroundIncreased arterial stiffness is an independent risk factor for cardiovascular disease. Arterial stiffness increases in obese individuals as compared to normal weight. While weight loss by calorie-restriction alone decreases arterial stiffness in obesity, it decreases muscle mass. Resistance training is recommended treatment for this frailty, but it can also increase arterial stiffness. Whole-body vibration (WBV) has recently been indicated as an alternative for resistance training. The present study aimed to examine whether lifestyle modifications combined with WBV decrease arterial stiffness in overweight and obese women.MethodsTwelve overweight and obese women (age: 30–48 years) completed a 12-week lifestyle-modification program (1200 kcal/day diet, brisk walking for 30 min, 3 days/week) and WBV (30–35 Hz, 30 min, 3 days/week).ResultsBefore and after this program, we measured body weight and indices of arterial stiffness, i.e., carotid-femoral pulse wave velocity (cfPWV) and brachial-ankle PWV (baPWV). Body weight, cfPWV, and baPWV of the overweight and obese women significantly decreased after this intervention. The concentration of plasma pentraxin 3, which has a cardioprotective effect, significantly increased after the program.ConclusionWe recommend the addition of WBV to classical lifestyle modifications to decrease arterial stiffness, which would reduce the risk of cardiovascular disease and muscle weakness in obese individuals. 相似文献

Objective
Arterial stiffness is associated with cardiovascular risk factors and atherosclerosis. Measurement of pulse wave velocity (PWV) is one of the most representative and noninvasive techniques for assessing arterial stiffness. We investigated the association of cerebral atherosclerosis with brachial-ankle PWV (baPWV) in acute ischemic stroke patients. If present, we sought to determine whether the relationship differed between atherosclerosis in the intracranial artery and atherosclerosis in the extracranial artery.Methods
We included 801 patients with acute ischemic stroke who had undergone angiographic study and baPWV measurement between January 2007 and May 2010. Patients with cerebral artery atherosclerosis were categorized into those with intracranial atherosclerosis, those with extracranial atherosclerosis and those with both intracranial and extracranial atherosclerosis. We determined factors that were associated with baPWV.Results
Univariate and multivariate analyses showed that high baPWV was significantly associated with older age, lower body mass index, higher brachial systolic pressure, and diabetes mellitus. Increased baPWV was associated with the presence of atherosclerosis (≥50% stenosis) in the intracranial cerebral artery as well as in both the intracranial and extracranial arteries, but not with atherosclerosis in the extracranial cerebral artery. The burden of intracranial cerebral atherosclerosis, which was assessed based on the number of arteries with atherosclerosis, was also closely associated with baPWV.Conclusion
Arterial stiffness was associated with the presence and burden of intracranial cerebral atherosclerosis in stroke patients, but was not associated with the extracranial cerebral atherosclerosis. These findings suggest a potential pathophysiological association between increased arterial stiffness and intracranial cerebral atherosclerosis. 相似文献6.

Background and aimsThe brachial-ankle pulse wave velocity (baPWV) is a marker for early atherosclerotic changes. Serum total bilirubin (TB) is an effective antioxidant and has been associated with carotid intima-media thickness, cardiovascular disease, stroke and peripheral arterial disease, all of which may be caused by arteriosclerosis. This study aimed to investigate the association of TB with arterial stiffness.Methods and resultsIn this cross-sectional study, we investigated the relationship between TB and baPWV in 2207 participants (1331 men, 876 women) in a general health examination. Different metabolic parameters were compared across TB quartiles. Age-adjusted mean values of baPWV gradually decreased with TB quartiles in men (Q1 = 1348, Q2 = 1266, Q3 = 1215, and Q4 = 1154 cm/s). However, the age-adjusted means of baPWV had no significance in women according to TB quartiles. Univariate analysis showed that age, smoking status, BMI, SBP, DBP, AST, ALT, GGT, TB, TG, and HDL-C were significantly associated with baPWV in men, whereas only age, BMI, SBP, DBP, TG and FPG were significantly associated with baPWV in women. In addition, BMI, SBP, TB, age, TG, and AST were significant factors in the multivariate model with baPWV in men; only BMI and FPG were significant factors with baPWV in women.ConclusionThe findings show that serum total bilirubin concentration is negatively correlated to arterial stiffness in Chinese men. Early detection of abnormal bilirubin levels could potentially serve as an early biomarker for arterial stiffness. 相似文献

Background and aimsHemoglobin (Hb) concentrations are known to be related to cardiovascular diseases. This study investigated the association between Hb levels and arterial stiffness, as assessed by measurement of the brachial-ankle pulse wave velocity (baPWV).Methods and results3576 adults (2139 males and 1437 females) from the general Chinese population who had their physical check-ups in the health examination centers of Jiangmen Central Hospital were enrolled into the study. The anthropometrics and laboratory data as well as the baPWV and Hb levels were subsequently obtained. Age-adjusted partial correlation and multivariable stepwise linear regression analyses were used to evaluate the relationships between Hb and baPWV for men and women separately. In both sexes, Hb levels were positively associated with body mass index, total cholesterol, low-density lipoprotein cholesterol, triglycerides, glutamic-pyruvic transaminase, γ-glutamyltranspeptidase, uric acid and baPWV, but negatively correlated with the estimated glomerular filtration rate. Multivariable linear regression analysis showed that Hb was significantly and independently associated with arterial stiffness in men (β = 0.043, 95% CI 0.010–0.077, p < 0.05) and women (β = 0.035, 95% CI 0.001–0.069, P < 0.05), after adjustment for confounding factors.ConclusionThe data indicate that high Hb concentration significantly correlate with increased baPWV in general Chinese population. 相似文献

BackgroundArterial stiffening is central in the vascular aging process. Traditionally, vascular research has focused on atherosclerotic vascular disease, whereas arterial stiffness has not attracted similar attention.ObjectiveSThe purpose of this study was to assess lifetime trajectories of arterial stiffening in Chinese populations facing a high burden of cardiovascular disease, with a particular focus on age–sex interactions and potential determinants.MethodsThis large-scale observational study comprised 2 independent cross-sectional population samples and 1 prospective cohort totaling 80,415 healthy subjects with brachial-ankle pulse wave velocity (baPWV) measurements available. Associations with potential risk conditions were analyzed using linear regression, linear random intercepts mixed models, and L1-regularized linear models.ResultsThe dynamics of age-dependent arterial stiffening differed in sexes, with stiffer vessel observed in men from adolescence to age 58 years and in women thereafter. The steeper increase in baPWV in women after menopause is partly explained by the fact that vascular risk factors are more strongly associated with arterial stiffness in women than in men. Age and systolic blood pressures were the strongest determinants of baPWV, whereas other vascular and metabolic risk factors, except low-density lipoprotein cholesterol, showed consistent associations of moderate strength.ConclusionsThe significant age–sex interaction in arterial stiffening provides an important clue of explanation for the heightened cardiovascular disease risk in postmenopausal women. Detailed knowledge on lifetime trajectories of arterial stiffening, and its potential risk factors is a prerequisite for the development of new prevention strategies counteracting vascular aging. 相似文献

Background and aimsThe effectiveness of statins commonly used to prevent stroke may depend on adherence to treatment. We examined the association between statin adherence and stroke risk among South Korean adults with hyperlipidemia.Methods and resultsThe data of 128,052 and 129,390 participants with hyperlipidemia for the purpose of studying the risks of ischemic and hemorrhagic stroke, respectively, were collected from the Korean National Health Insurance Service-National Sample Cohort between 2002 and 2013. Participants were divided into groups according to statin adherence, calculated as the proportion of days covered (PDC; poor, moderate, good). The risk of ischemic and hemorrhagic stroke were analyzed using a Cox proportional hazards model. Individuals with poor PDC exhibited higher risks of ischemic and hemorrhagic stroke than those with good PDC (ischemic stroke: hazard ratio [HR] = 1.09, 95% confidence interval [CI] = 1.03–1.15, hemorrhagic stroke: HR = 1.37, 95% CI = 1.22–1.54). Women with poor PDC were at higher risk of ischemic stroke than those with good PDC (HR = 1.17, 95% CI = 1.09–1.26), while men with poor PDC exhibited a higher risk of hemorrhagic stroke than those with good PDC (HR = 1.55, 95% CI = 1.27–1.90). Individuals with disabilities who had poor PDC were at higher risk of ischemic stroke than those with good PDC (HR = 1.55, 95% CI = 1.24–1.93).ConclusionsWe detected a significant association between statin adherence and ischemic and hemorrhagic stroke risk. Therefore, hyperlipidemia patients should adhere to statin treatment; such interventions are required to reduce the stroke risk. 相似文献

Background:The study aimed to estimate the prevalence, distribution, and correlates of ideal cardiovascular health (CVH) among individuals (20–69 years) in Mongolia.Method:Cross-sectional data were analyzed from 4,516 individuals (20–69 years, mean age = 42.3 years) who participated in the Mongolia STEPS survey in 2019, who had complete measurement of CVH metrics and no history of cardiovascular disease. Ideal CVH measures included non-smoking, healthy diet, physical activity, fasting blood glucose <100 mg/dL, body mass index (<23 kg/m2), total cholesterol <200 mg/dL, and blood pressure <120/<80 mmHg).Results:The prevalence of five to seven ideal CVH metrics was 27.7% in 2019. Most Mongolians had ideal total cholesterol (77.4%), ideal smoking (67.8%), ideal fasting glucose (73.8%) and ideal physical activity (66.0%), while a lower prevalence was found for ideal blood pressure (42.4%), ideal body mass index (31.4%), and ideal healthy diet (1.8%). The prevalence of poor smoking, poor fruit/vegetable intake, poor fasting glucose, poor blood pressure, and poor total cholesterol was higher in men than in women, while poor physical activity was higher in women than in men, and poor BMI did not differ by sex. In the adjusted logistic regression analysis, older age, male sex, and belonging to the Khalkh ethnic group were negatively associated, and a higher number of adult household members was positively associated with meeting the ideal 5–7 CVH metrics.Conclusions:The proportion of meeting 5–7 ideal CVH metrics was moderate among adults in Mongolia. Primary and secondary prevention programmes should be strengthened to improve CVH in Mongolia, considering identified associated factors. 相似文献

The association between arterial stiffness and decline in kidney function in patients with mild to moderate chronic kidney disease (CKD) is not well established. This study investigated whether pulse wave velocity (PWV) and pulse pressure (PP) are independently associated with glomerular filtration rate (GFR) and rapid decline in kidney function in early CKD. Carotid femoral PWV (cfPWV), brachial‐ankle PWV (baPWV), and PP were measured in a cohort of 913 patients (mean age, 63±10 years; baseline estimated GFR, 84±18 mL/min/1.73 m2). Estimated GFR was measured at baseline and at follow‐up. The renal outcome examined was rapid decline in kidney function (estimated GFR loss, >3 mL/min/1.73 m2 per year). The median follow‐up duration was 3.2 years. Multivariable adjusted linear regression model indicated that arterial PWV (both cfPWV and baPWV) and PP increased as estimated GFR declined, but neither was associated with kidney function after adjustment for various covariates. Multivariable logistic regression analysis found that cfPWV and baPWV were not associated with rapid decline in kidney function (odds ratio [OR], 1.39, 95% confidence interval [CI], 0.41–4.65; OR, 2.51, 95% CI, 0.66–9.46, respectively), but PP was (OR, 1.22, 95% CI, 1.01–1.48; P=.045). Arterial stiffness assessed using cfPWV and baPWV was not correlated with lower estimated GFR and rapid decline in kidney function after adjustment for various confounders. Thus, PP is an independent risk factor for rapid decline in kidney function in populations with relatively preserved kidney function (estimated GFR ≥30 mL/min/1.73 m2). 相似文献

Background and aimsLow high-density lipoprotein cholesterol (HDL-c) is a risk factor for cardiovascular disease. Brachial-ankle pulse wave velocity (baPWV) is an indicator of arterial stiffness, which is recognized as a predictor of cardiovascular disease. The aim of this study was to investigate the association between HDL-c and baPWV among middle-aged and elderly Chinese.MethodsA total number of 1133 Chinese (430 men, 703 women) aged from 50 to 90 years old were recruited from Shanghai downtown district. The baPWV and major cardiovascular risk factors of the participants were measured.ResultsSerum HDL-c was negatively correlated with baPWV (r = ?0.143, P < 0.001) after adjustment for age and gender. Multivariate linear regression analysis demonstrated that age (P < 0.001), systolic blood pressure (P < 0.001), HDL-c (P < 0.001), smoking (P = 0.001), BMI (P = 0.002), fasting plasma glucose (P = 0.004), and white blood cell (P = 0.005) were independently associated with baPWV. After multiple adjustments, participants in the highest quartile of HDL-c had an odds ratio of 0.442 (95% CI 0.268–0.729) for developing high arterial stiffness compared with participants in the lowest quartile. The association remained significant after further adjustment for major cardiovascular risk factors.ConclusionHDL-c has an independent protective effect on arterial stiffness in middle-aged and elderly Chinese. Early detection of HDL-c level is important in high risk populations with arterial stiffness. Increasing HDL-c level may be an attractive therapeutic target for the prevention of arterial function and subsequent disease. 相似文献

Background and aimsArterial stiffness and increased intima-media wall thickness are two of the main predictors of cardiovascular disease (CVD). We evaluated whether brachial-ankle pulse wave velocity (baPWV) and common carotid artery intima-media wall thickness (CCA-IMT) are correlated with alcohol consumption in a cross-sectional study among Korean men and women aged 40 years and over.Methods and resultsAll 5539 subjects (2121 men and 3418 women) were participants in the Multi-Rural Communities cohort (MRcohort) study, a part of the Korean Genome Epidemiology Study (KoGES). The baPWV was positively correlated with alcohol consumption in men (p for trend <0.0001). Age (middle-aged versus elderly) modified the effect of alcohol consumption on PWV. On the other hand CCA-IMT decreased with alcohol consumption in men. There was no favorable zone of alcohol consumption in terms of baPWV and CCA-IMT. Adjustment for lipid profiles substantially attenuated the relationship between alcohol consumption and CCA-IMT. There was no clear relation between alcohol consumption and baPWV/CCA-IMT in women.ConclusionsAlong with a linear harmful relationship between alcohol consumption and arterial stiffness in men there may also be a beneficial relationship between alcohol consumption and carotid intima-wall thickness. The effect of alcohol on arterial stiffness may be slightly stronger in elderly men, and the effect of alcohol on CCA-IMT may be mediated by lipid factors. 相似文献

Background and aimWe assessed the Ideal Cardiovascular Health (CVH) in Brazilian adolescents according to demographics and socioeconomic characteristics.Methods and resultsThis is a cross-sectional study with data from the Study of Cardiovascular Risks in Adolescents (ERICA), with a nationwide representative sample of 36,956 Brazilian adolescents, aged 12–17 years, enrolled in public and private schools. The CVH metrics considered were body mass index (BMI), physical activity, smoking, healthy diet score, blood pressure, fasting plasma glucose, and total cholesterol. The demographics and socioeconomic characteristics analyzed were sex, age, race/skin color, and type of school attended. The study design was considered, and the significant difference determined by the non-overlapping of 95% Confidence Interval. The mean ideal CVH score was 4.0, higher for females, adolescents aged 15–17 years, and students from private schools. The prevalence of ideal fasting plasma glucose was 96%, of non-smoking 95.6%, of ideal blood pressure 75.5%, of ideal BMI 73.2%, of ideal total cholesterol 55.4%, of ideal physical activity 45.2%, and only 0.5% had an ideal diet. The prevalence of ideal CVH metrics varied according to demographics and socioeconomic characteristics.ConclusionFemales, older adolescents, and students who attended private school had a better CVH. Demographics and socioeconomic characteristics were associated with CVH metrics. The low ideal proportions found for diet and physical activity are of concern and reinforce the need for food and nutritional educational actions designed to promote healthy behaviors in adolescence to prevent the development of cardiovascular diseases. 相似文献

Background and aimsThe role of serum uric acid (SUA) in stroke remains controversial and analyses of changes in SUA and stroke are limited. The objective of the study was to investigate the associations of changes in SUA with stroke and its subtypes (ischemic and hemorrhagic stroke).Methods and resultsA total of 51 441 participants (mean age 52.69 ± 11.71 years) without history of myocardial infarction or stroke were enrolled. Participants were divided into four groups based on SUA level changes during 2006 and 2010: stable low, increasing, decreasing, and stable high. SUA score was quantified on a 3-point scale with 1 point awarded for hyperuricemia at either year 2006, 2008 or 2010. Multivariate Cox proportion models were used to calculated hazard ratios (HRs) and their 95% confidence intervals (CIs). During 7.03-year follow up, 1611 stroke (1410 ischemic stroke, 199 hemorrhagic stroke, and 47 subarachnoid hemorrhage) were identified. Participants with stable high SUA had higher risk of hemorrhagic stroke, the HR was 1.93 (95% CI: 1.06–3.51), compared to those with stable low SUA. Furthermore, cumulative high SUA exposure also increased the risk of hemorrhagic stroke, the HR (95%CI) was 2.99 (1.55–5.74), compared with cumulative low SUA exposure. However, no significant evidence indicated changes in SUA was associated with the risk of total and ischemic stroke, the HRs (95% CIs) were 0.98 (0.74–1.29) and 0.88 (0.65–1.19), respectively.ConclusionsStable high SUA was positively associated with the risk of hemorrhagic stroke, but not with total and ischemic stroke risk. 相似文献

Although brachial‐ankle pulse wave velocity (baPWV) has been widely used as an index of arterial stiffness, no consensus exists about whether baPWV can reflect central aortic stiffness. The authors investigated the association between baPWV and invasively measured aortic pulse pressure (APP) in a total of 109 consecutive patients (mean age, 62.3 ± 11.3 years; 67.9% men). Most patients (91%) had obstructive coronary artery disease, and mean baPWV and APP values were 1535 ± 303 cm/s and 66.8 ± 22.5 mm Hg, respectively. In univariate analysis, there was a significant linear correlation between baPWV and APP (r = .635, P < .001). The correlation between baPWV and APP remained significant even after controlling for potential confounders (β = 0.574, P < .001; R2 = .469). Arterial stiffness measured by baPWV showed a strong positive correlation with invasively measured APP, independent of clinical confounders. Therefore, baPWV can be a good marker of central aortic stiffness. 相似文献

ObjectivesArterial stiffness is correlated with left ventricular hypertrophy (LVH) and is susceptible to left ventricular performance. Therefore, if left ventricular systolic function is unknown, the relationship between arterial stiffness and LVH is controversial. This study was to assess the impact of the ratio of brachial pre-ejection period (bPEP) to brachial ejection time (bET), a marker of left ventricular systolic function, on the relationship between brachial-ankle pulse wave velocity (baPWV) and LVH.MethodsA total of 1146 patients were included in the study. The baPWV and bPEP/bET were measured using an ABI-form device. Patients were classified into four groups. Groups 1, 2, 3, and 4 were patients with bPEP/bET ≤ 0.38 and baPWV below the median, bPEP/bET > 0.38 but baPWV below the median, bPET/bET ≤ 0.38 but baPWV above the median, and bPET/bET > 0.38 and baPWV above the median, respectively.ResultsPatients in groups 3 and 4 (high baPWV) and patients in group 2 (low baPWV but high bPEP/bET) were associated with increased left ventricular mass index (LVMI) and LVH (all P < 0.001). In a multivariate model, baPWV was significantly associated with LVMI (P = 0.007) and LVH (P = 0.025). Further adjustment for bPEP/bET made the association between baPWV and LVMI (P = 0.150) and LVH (P = 0.173) disappear.ConclusionsThe bPEP/bET has an important impact on the relationship between baPWV and LVH. Therefore, the value of bPEP/bET obtained from the same examination should be considered while interpreting the relationship between baPWV and LVH. 相似文献

Blood pressure (BP) changes with age. We conducted a cross-sectional study in rural Chinese adults to investigate: (1) what is the relationship between age, arterial stiffness, and BP in Chinese men and women; and (2) to what degree can the age–BP relationship be explained by arterial stiffness, controlling for other covariables.These analyses included a total of 1688 subjects (males/females: 623/1065), aged 40 to 88 years. Among them, 353 (20.9%) had hypertension (defined as systolic blood pressure (SBP) ≥140 mm Hg or diastolic blood pressure (DBP) ≥90 mm Hg). Arterial stiffness was measured by brachial–ankle pulse wave velocity (baPWV).baPWV appeared to be more strongly correlated with BP (including SBP, DBP, mean arterial pressure [MAP], pulse pressure [PP]) than age (P < 0.001 for comparisons between Spearman correlation coefficients). Furthermore, baPWV was associated with BP (including SBP, DBP, MAP, and PP) and risk of hypertension in a dose–response fashion, independent of age; in contrast, the age–BP associations were either attenuated or became negative after adjusting for baPWV.Arterial stiffness appears to be an independent contributor to hypertension, even after adjusting for age and other covariables. In contrast, age–BP associations became attenuated or negative after adjusting for baPWV. The utility of baPWV as a diagnostic, prognostic, and therapeutic indicator for hypertension warrants further investigation. 相似文献

Systemic lupus erythematosus (SLE) is associated with premature atherosclerosis. Increasing arterial stiffness is closely associated with atherosclerotic cardiovascular diseases, and pulse wave velocity (PWV) is considered to be an indicator of arterial stiffness. The objective of this study was to identify the relationship between brachial-ankle pulse wave velocity (baPWV) and cardiovascular risk factors in patients with SLE. Age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBS), plasma lipid profile, plasma homocysteine, thiobarbituric acid reactive substances (TBARS), baPWV, ankle-brachial index (ABI), and SLE-related factors were determined in a total of 83 SLE patients (12 males and 71 females). All SLE patients were further classified into two subgroups according to baPWV value (baPWV < 1400 cm/s, n=37 versus baPWV > 1400 cm/s, n=46). The mean baPWV value of studied SLE patients was 1520 +/- 381 cm/s. Age, BMI, SBP, DBP, FBS, TBARS and homocysteine levels were significantly higher in SLE patients with baPWV value > 1400cm/s than in SLE patients with baPWV value < 1400cm/s. In addition, baPWV correlated significantly with age, SBP, DBP, FBS and homocysteine. Moreover, stepwise multiple regression analysis showed that age and SBP were independently associated with baPWV. The results of this study indicate a possible link between vascular stiffness measured by baPWV and cardiovascular risk factors in patients with SLE. 相似文献

BackgroundArterial stiffness, peripheral artery disease and left ventricular systolic dysfunction contributed to left ventricular hypertrophy (LVH). Using an ABI-form device, we can obtain brachial-ankle pulse wave velocity (baPWV), ankle-brachial index (ABI) and the ratio of brachial pre-ejection period to ejection time (bPEP/bET), which are markers for arterial stiffness, peripheral artery disease and left ventricular systolic function, respectively. The aim of this study was to assess whether “BAP score” calculated from the 3 measures of baPWV, ABI and bPEP/bET is associated with LVH.MethodsA total of 1,146 patients were included in the study. BAP score was calculated based on a point system in which 1 point was assigned for baPWV above the median value of 1670 cm/s, ABI < 0.9 or $ 1.3 in either leg and bPEP/bET > 0.38.ResultsThere was a significant trend for a stepwise increase in the left atrial diameter, left ventricular mass index (LVMI) and the prevalence of LVH and a stepwise decrease in the left ventricular ejection fraction corresponding to advancement in BAP score from 0 to 3. In addition, increased BAP score is significantly associated with increased LVMI and LVH.Conclusionsour results demonstrated increased BAP score was related to increased LVMI and LVH independent of traditional risk factors such as old age, diabetes, hypertension, obesity, anemia, hyperlipidemia and chronic kidney disease. Therefore, the BAP score obtained from the same examination might be useful and convenient in identifying patients with increased LVMI and LVH. 相似文献
