Aim. The association of pressure load with elasticity in vascular system has not been studied fully. We proposed a hypothesis whether gender could modify the association of blood pressure variability (BPV) and arterial stiffness assessed by carotid-femoral pulse wave velocity (CF-PWV) in prehypertensive patients. Methods. 24h ambulatory blood pressure monitoring (24h-ABPM) and CF-PWV were measured in 723 participants with prehypertension. Univariate and multivariate regression analyses of these clinical and biological parameters were performed in total population, male and female. Results. A total of 723 participants (mean age 59.76 ± 12.37years, male 329 and female 394) were enrolled into the study. Compared with female, body mass index (BMI), fasting plasma glucose (FPG), uric acid (UA), and homocysteine (HCY) were significantly higher (all p < 0.05). Arterial stiffness (CF-PWV, male versus female, 10.89 ± 2.50 versus 10.33 ± 2.13 m/s, p=0.004) and BPVs (male versus female, 24 h SBPV 13.2 ± 5.11 versus 13.03 ± 5.20; 24 h DBPV 10.34 ± 3.87 versus 9.64 ± 3.59; N SBPV 11.90 ± 6.60 versus 10.94 ± 4.79; N DBPV 9.64 ± 5.87 versus 8.20 ± 4.48, all p<0.05) were higher in male. Multivariable linear regression analysis showed that 24 h BPV were linearly and positively related to CF-PWV in total population (24h SBPV, B=0.033; 24 h DBPV, B=0.035, both P<0.05) and female (24h SBPV, B=0.041; 24h DBPV, B=0.067, both P<0.05) independent of traditional risk factors and medications. Conclusion. BPV was independently associated with arterial stiffness in total population and the relation was modified by gender. 24 h BPVs in prehypertensive patients were useful to identify the early arterial stiffness.

ObjectiveAlthough blood pressure (BP) is a major determinant of arterial stiffness, whether high pulse wave velocity (PWV) adversely influences cardiac parameters and cardiovascular (CV) outcome in patients without high BP remains unclear.MethodsOutpatients without high BP (n=320), defined as systolic BP ≥140 mm Hg, were enrolled in this retrospective study. At baseline, all patients underwent echocardiography and multidetector CT to determine the coronary artery calcification (CAC) score. Arterial stiffness was assessed based on brachial-ankle PWV (baPWV), from which patients were classified into two groups: those with high (≥18 m/s, n=89) and low baPWV (<18 m/s, n=231). Cardiac parameters and CV event incidence during the follow-up period were compared between these groups.ResultsIn multivariable linear regression analysis, baPWV was significantly associated with CAC score and serum N-terminal pro-brain natriuretic peptide hormone level, after adjustment for confounding factors. In multivariable logistic regression analysis, baPWV ≥18 m/s was significantly associated with CAC score ≥400 (OR 2.466, 95% CI 1.012 to 6.009, p=0.0471). Kaplan-Meier analysis showed that the high-baPWV group experienced more CV events during the 575 days of follow-up (20% vs 6%, p=0.0003).ConclusionsHigh baPWV was associated with greater CAC and a high risk of a future CV event, especially coronary artery disease, even in patients without high BP.

Abstract Background Arterial stiffness (AS) is an established and potentially modifiable risk factor for cardiovascular disease associated with chronic kidney disease (CKD). There have been few studies to evaluate the progression of AS over time or factors that contribute to this, particularly in early CKD. We therefore investigated AS over 5 years in an elderly population with CKD Stage 3 cared for in primary care. Methods A total of 1741 persons with an estimated glomerular filtration rate of 30–59 mL/min/1.73 m2 underwent detailed clinical and biochemical assessment at baseline and Years 1 and 5. Carotid to femoral pulse wave velocity (PWV) was measured to assess AS using a Vicorder device. Results 970 participants had PWV assessments at baseline and 5 years. PWV increased significantly by a mean of 1.1 m/s (from 9.7 ± 1.9 to 10.8 ± 2.1 m/s). Multivariable linear regression analysis identified the following independent determinants of ΔPWV at Year 5: baseline age, diabetes status, baseline systolic blood pressure (SBP) and diastolic blood pressure, baseline PWV, ΔPWV at 1 year, ΔSBP over 5 years and Δserum bicarbonate over 5 years (R2 = 0.38 for the equation). Conclusions We observed a clinically significant increase in PWV over 5 years in a cohort with early CKD despite reasonably well-controlled hypertension. Measures of BP were identified as the most important modifiable determinant of ΔPWV, suggesting that interventions to prevent arterial disease should focus on improved control of BP, particularly in those who evidence an early increase in PWV. These hypotheses should now be tested in prospective trials.

Objective We assessed differences and correlations between 24-hour ambulatory blood pressure (ABP) and office blood pressure (OBP) monitoring. Methods We conducted an observational study among 85 untreated patients with essential hypertension and measured 24-hour ABP, OBP, target organ damage (TOD) markers, and metabolism indexes. Variance analysis and the Pearson method were used to compare differences and correlation between the two methods. The Spearman or Pearson method was applied to compare the correlation between TOD markers, blood pressure index, and metabolism index. Linear regression analysis was applied to estimate the quantitative relationship between the blood pressure index and TOD markers. Results There were significant differences in the mean and variance of systolic blood pressure (SBP) and diastolic blood pressure and a positive correlation between ABP and OBP. Correlations between the left ventricular mass index (LVMI) and average ambulatory SBP, daytime ambulatory SBP, nighttime ambulatory SBP, and fasting blood glucose were significant. Correlations between left intima-media thickness (IMT) and average ambulatory SBP, nighttime ambulatory SBP, right IMT, and nighttime ambulatory SBP were significant. In linear regression analysis of the LVMI (y) and ambulatory SBP (x), the equation was expressed as y = 0.637*x. Conclusion Nighttime ambulatory SBP may be an optimal predictor of TOD.

Arterial Stiffness Index

Chronic kidney disease (CKD) affects approximately two million people (in a population of 20 million) in Romania. Hypertension is often associated with CKD and both (hypertension and CKD) are risk factors for cardiovascular (CV) events. Ambulatory blood pressure monitoring (ABPM) is increasingly used all around the world for the diagnosis and monitoring of BP (blood pressure) because it is proven that the ABPM is superior to office BP measurements in evaluating patients with hypertension, with or without CKD. Reduced nocturnal BP fall (non-dipping or reverse-dipping patterns) is associated with target organ damage, especially kidney disease and the proportion of non-dippers and reverse-dippers patients increases progressively with the reduction of glomerular filtration rate (GFR). Another ABPM parameter, ambulatory arterial stiffness index (AASI), is an index which was recently proposed for the evaluation of arterial stiffness (a better tool than PP). It has prognostic value for cardiac death and stroke and several studies have showed that is negatively related to eGFR and is positively related to albuminuria. Hyperbaric area index (HBI) might be considered a novel sensitive marker [independent of patterns of NBPC (nocturnal BP change)] for the reduction of kidney function. These facts suggest that ABPM offers multiple useful data with impact, not only in future CV and renal outcomes assessment, but also in the treatment and management of hypertensive patients with CKD.
