Short-Term Variability of Both Brachial and Aortic Blood Pressure is Increased in Patients with Immune-mediated Chronic Inflammation. High Blood Press Cardiovasc Prev 2024:10.1007/s40292-024-00651-3. [PMID: 38819777 DOI: 10.1007/s40292-024-00651-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Accepted: 05/14/2024] [Indexed: 06/01/2024] Open
Abstract
INTRODUCTION Blood pressure (BP) variability (BPV) has emerged as an indicator of subclinical organ damage and an independent predictor of cardiovascular disease (CVD) morbidity and mortality in high-risk populations. AIM We aimed to assess short-term variability of both brachial and aortic BP in psoriasis, a common immune-mediated inflammatory disorder characterized by increased CVD risk. METHODS Psoriasis patients and non-psoriasis individuals had their BP assessed throughout a 24 h period (Mobil-O-Graph device). Brachial and aortic BPV during the 24 h and the respective daytime and nighttime periods was calculated from relevant ambulatory BP profiles. In-house software was applied to automatically calculate average real variability (ARV) of brachial and aortic systolic (bSBP, aSBP) and diastolic BP (bDPB, aDBP), and the weighted standard deviation (wSD) of 24 h bSBP/aSBP. 24 h pulse wave velocity (PWV) and augmentation index (AIx) were used as widely applied markers of arterial stiffness. RESULTS Psoriasis patients (n = 74) presented increased ARV of 24 h and daytime bSBP/aSBP, and increased ARV of 24 h and daytime bDBP/aDBP, compared to controls (n = 40). PWV and AIx correlated with ARV of 24 h bSBP/aSBP, daytime bSBP/aSBP, while PWV further correlated with ARV of nighttime aSBP. The observed associations with PWV, yet not AIx, with indices of BPV remained significant after adjusting for CVD risk factors. CONCLUSIONS This is the first study reporting increased 24 h variability of both brachial and aortic BP in psoriasis. The association of short-term BPV with arterial stiffness implies a potential role of BPV in terms of CVD risk stratification in patients with chronic immune-mediated inflammation.

Abstract
We aimed at investigating the association of personal and work-related burnout with blood pressure and hypertension among working adults in Chile. We conducted a cross-sectional study among 1872 working adults attending the Hospital del Trabajador in Santiago, Chile, between September 2015 and February 2018. The Copenhagen Burnout Inventory was used to assess personal and work-related burnout. Blood pressure was measured by medical practitioners. Multivariable linear and logistic regressions were used to estimate the association of burnout status with systolic blood pressure (SBP), diastolic blood pressure (DBP), and hypertension. After adjusting for confounders, participants with both types of burnout had a 1.66 (95% confidence interval [CI]: 0.02-3.30) mmHg higher mean DBP than those without burnout. The odds of isolated diastolic hypertension among the participants with only personal burnout and both types of burnout were 2.00-fold (odds ratio [OR] = 2.00; 95% CI: 1.21-3.31) and 2.08-fold (OR = 2.08; 95% CI: 1.15-3.78) higher than those without burnout. The odds of combined systolic/diastolic hypertension among the participants with only work-related burnout increased by 59% (OR = 1.59; 95% CI: 1.01-2.50) compared with those without burnout. Both work-related and personal burnouts were associated with increased DBP and odds of diastolic hypertension among working adults in Chile.

Diabetol Metab Syndr 2022; 14:161. [PMID: 36309720 PMCID: PMC9617408 DOI: 10.1186/s13098-022-00927-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Accepted: 10/07/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Insulin resistance (IR) is an important contributor to the development of hypertension (HTN), and the triglyceride-glucose (TyG) index has been proposed as a simple, reliable marker of IR. This study investigated the association between the TyG index and blood pressure (BP) elevation in a large general population. METHODS The study enrolled 15,721 adults with no history of cardiometabolic diseases from the 2016-2019 Korea National Health and Nutrition Examination Survey. Participants were classified into quartiles based on the TyG index and BP was categorized as normal BP, elevated BP, pre-HTN, and HTN. The associations of the TyG index with BP categories were assessed using multivariate multinomial logistic regression models with normal BP as the reference group. RESULTS The mean systolic/diastolic BP and prevalence of HTN increased with the TyG index (P for trend < 0.001). The continuous TyG index had a strong dose-response relationship with increased odds of elevated BP, pre-HTN, and HTN. Compared with the lowest TyG index quartile, the highest TyG index quartile was significantly associated with higher odds of having elevated BP (odds ratio [OR], 1.52; 95% confidence interval [CI], 1.24-1.87; P for trend < 0.001), pre-HTN (OR, 2.22; 95% CI, 1.95-2.53; P for trend < 0.001), and HTN (OR, 4.24; 95% CI, 3.49-5.16; P for trend < 0.001). CONCLUSION We found that a higher TyG index was positively associated with the risk of increased BP in normal healthy individuals. This study suggests that the TyG index might serve as a potential predictor of HTN. However, further studies with larger sample sizes and various target populations in longitudinal designs are needed.

The baseline and repeated measurements of DBP to assess in-hospital mortality risk among critically ill patients with acute myocardial infarction: A retrospective cohort study. Medicine (Baltimore) 2022; 101:e30980. [PMID: 36221379 PMCID: PMC9543008 DOI: 10.1097/md.0000000000030980] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Accepted: 09/06/2022] [Indexed: 01/05/2023] Open
Abstract
Changes in diastolic blood pressure (DBP) are common in patients with acute myocardial infarction (AMI). The relationship between the dynamic change of DBP and in-hospital mortality among patients with AMI remains unclear. This study aimed to explore the importance of DBP during disease development among patients with AMI. We performed a retrospective cohort study involving patients from the Medical Information Mart for Intensive Care III database, which included > 40,000 patients admitted to the intensive care unit (ICU). Overall, 3209 adult AMI admissions were identified. We extracted the clinical and laboratory information in the patients with AMI. Cox proportional hazards models were used to evaluate the prognostic values of baseline DBP. We used the generalized additive mixed model (GAMM) to compare trends in DBP over time among survivors and non-survivors, after adjusting for potential confounders. During the ICU stay, 189 patients died (mortality rate, 6.36%). The age of each non-survivor together with the variations in DBP over time from admission to the time of death is of great importance to the scientific community. Cox multivariable regression analysis displayed that after adjusting for confounding factors, ascended baseline DBP was an important hazard factor for hospital deaths (hazard ratio, 1.02; 95% confidence interval, 1.01-1.03; P = .003). Based on GAMM, DBP in the death group was markedly lower than that of the surviving group. Moreover, the difference between the two groups showed an increasing trend within 3 days after ICU admission. After adjusting for various variables, the results were stable. DBP significantly contributed to in-hospital mortality among patients with AMI. There was a nonlinear correlation between baseline DBP and in-hospital mortality among patients with AMI, and the DBP of the non-survivors decreased within the first 3 days after ICU admission. However, the causality cannot be deduced from our data.

Abstract
BACKGROUND/AIMS The optimal systolic blood pressure (SBP) goal for elderly patients with hypertension, especially to reduce cardiovascular disease (CVD) incidence and improve outcome, is unclear. This study aimed to evaluate the beneficial effects of intensive treatment for hypertension on the incidence of CVD in elderly Korean patients. METHODS The HOW to Optimize eLDerly systolic Blood Pressure (HOWOLD-BP) trial is a multicenter, parallel-design, open-label, randomized controlled trial designed to evaluate whether intensive treatment (SBP ≤ 130 mmHg) will provide more benefits in lowering the incidence and mortality associated with CVD than standard treatment (SBP ≤ 140 mmHg) in elderly patients with hypertension aged ≥ 65 years. For this study, eleven university hospitals in Korea will enroll approximately 3,176 elderly patients with hypertension between 2019 and 2022. Patients will be requested to visit the clinic every 4 months for the first year and every 6 months thereafter for 36 months. Parameters, including clinic and home blood pressure, anthropometric and laboratory findings, and frailty assessments, will be collected according to the standardized protocol. The primary outcome is a composite of CVD (acute coronary syndrome, stroke, and heart failure) incidence and cardiovascular deaths. RESULTS As of December 2021, 1,655 participants had been enrolled in the study, including 831 patients in the standard group and 824 patients in the intensive group. CONCLUSION The HOWOLD-BP trial is the first study performed in Korea to evaluate the beneficial effects of intensive blood pressure treatment on CVD in elderly patients with hypertension. The results of this study will help clarify the appropriate target SBP for this population.

Abstract
AIM: Health problems of the elderly in addition to purely medical constitute a complex and quite acute social, economic, psychological, and spiritual problem, which are growing unstoppably everywhere in the world. The main purpose of this study is to assess the general health of the elderly, to identify the most common pathologies, and to describe the role and responsibilities of the nurse in the elderly with cardiovascular, neurological, and orthopedic diseases, in all patients in geriatric clinics.
METHODS: The method used during this study was conducted through a questionnaire of the elderly in geriatric centers. The paper includes data on patients during the period April–June, 2020.
RESULTS: Data were observed on 300 elderly persons of whom 100 persons or 33% were female and 200 persons or 67% were male. The mean age of patients was 90 ± 65 years. These elderly people were given information about living conditions, social problems, diseases they had, etc. The most common pathologies of these elderly people studied were cardiovascular problems 25%, orthopedic problems 31%, and neurological problems 43%. We see that women are more predisposed to cardiovascular problems in 66% of cases compared to men in 34% of cases; most predisposed to orthopedic problems are again women in 55% of cases compared to men in 45% of cases and more predisposed to neurological problems are men in 60% of cases and women in 40% of cases, it is significant (p < 0.001).
CONCLUSIONS: From the above data, it is noticed that almost all the elderly have a concomitant disease. The role of the nurse should be to focus on the daily monitoring of the patient’s condition, to identify in time the possible risks, and to explain to the patient how to take the therapy, how long to take this therapy, what may be the side effects and how medications should be combined.

Abstract
BACKGROUND SBP and DBP have important associations with cardiovascular events, but are seldom considered simultaneously. OBJECTIVES This study sought to simultaneously analyze systolic blood pressure (SBP) and diastolic blood pressure (DBP) measurements on the associated risk of a primary composite outcome of all-cause mortality, myocardial infarction (MI), congestive heart failure (CHF), or stroke. METHODS This study analyzed ALLHAT (Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial) data, which randomized adults to chlorthalidone, amlodipine, or lisinopril. The authors evaluated the simultaneous association of repeated SBP and DBP measurements on the primary composite outcome, and each outcome using proportional hazards regression. The authors report hazard ratios using a "heat map" to represent high and low risk according to SBP and DBP combinations. RESULTS During a median follow-up of 4.4 years (interquartile range: 3.6-5.4 years), 33,357 participants experienced 2,636 MIs, 866 CHF events, 936 strokes, and 3,700 deaths; 8,138 patients (24.4%) had at least 1 event. For the composite outcome, all-cause mortality, MI, and CHF, a U-shaped association was observed with SBP and DBP, but the SBP and DBP associated with the lowest hazards differed for each outcome. For example, SBP/DBP of 140-155/70-80 mm Hg was associated with the lowest HR for all-cause mortality, compared with 110-120/85-90 mm Hg for MI and 125-135/70-75 mm Hg for CHF. In contrast, the association of SBP and stroke was linear. CONCLUSIONS The risk pattern of SBP and DBP differs by clinical outcomes, and the SBP and DBP associated with the lowest risk. Our results suggest individualization of blood pressure targets may depend in part on the cardiovascular event for which the patient is most at risk.

Abstract
Residential mobility is linked to higher incidence of cardiovascular disease (CVD) and mortality. A mechanism by which residential relocation may impact health is through the disruption of social networks. To examine whether moving to a new city is associated with increased CVD risk and whether the extent to which movers rebuild their social network after relocating predicts improved CVD risk and psychosocial well-being, recent movers (n = 26), and age- and sex-matched nonmovers (n = 20) were followed over 3 months. Blood pressure, C-reactive protein/albumin ratio (CRP/ALB), social network size, and psychosocial well-being were measured at intake (within 6 weeks of residential relocation for movers) and 3 months later. Multiple regression indicated higher systolic blood pressure (SBP) for movers (M = 107.42, SD = 11.39), compared with nonmovers (M = 102.37, SD = 10.03) at intake, though this trend was not statistically significant. As predicted, increases in movers' social network size over 3 months predicted decreases in SBP, even after controlling for age, sex, and waist-to-hip ratio, b = -2.04 mmHg, 95% CI [-3.35, -.73]. Associations between increases in movers' social ties and decreases in depressive symptoms and stress were in the predicted direction but did not meet the traditional cutoff for statistical significance. Residential relocation and movers' social network size were not associated with CRP/ALB in this healthy sample. This study provides preliminary evidence for increased SBP among recent movers; furthermore, it suggests that this elevation in CVD risk may decrease as individuals successfully rebuild their social network.

Impact of blood pressure control on retinal microvasculature in patients with chronic kidney disease. Sci Rep 2020; 10:14275. [PMID: 32868805 PMCID: PMC7459351 DOI: 10.1038/s41598-020-71251-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2020] [Accepted: 08/13/2020] [Indexed: 12/24/2022] Open
Abstract
Chronic kidney disease (CKD) is an emerging disease worldwide. We investigated the relationship between blood pressure (BP) control and parafoveal retinal microvascular changes in patients with CKD. This case–control study enrolled 256 patients with CKD (stage 3–5) and 70 age‐matched healthy controls. Optical coherence tomography angiography showed lower superficial vascular plexus (SVP) vessel density, lower deep vascular plexus (DVP) vessel density, and larger SVP flow void area in the CKD group. The BP parameters at enrollment and during the year before enrollment were collected in patients with CKD. Partial correlation was used to determine the relationship between BP parameters and microvascular parameters after controlling for age, sex, diabetes mellitus, axial length, and intraocular pressure. The maximum systolic blood pressure (SBP) (p = 0.003) and within-patient standard deviation (SD) of SBP (p = 0.006) in 1 year were negatively correlated with SVP vessel density. The average SBP (p = 0.040), maximum SBP (p = 0.001), within-patient SD of SBP (p < 0.001) and proportion of high BP measurement (p = 0.011) in 1 year were positively correlated with the SVP flow void area. We concluded that long-term SBP was correlated with SVP microvascular injury in patients with CKD. Superficial retinal microvascular changes may be a potential biomarker for prior long-term BP control in these patients.

Abstract
BACKGROUND The relationship between outpatient systolic and diastolic blood pressure and cardiovascular outcomes remains unclear and has been complicated by recently revised guidelines with two different thresholds (≥140/90 mm Hg and ≥130/80 mm Hg) for treating hypertension. METHODS Using data from 1.3 million adults in a general outpatient population, we performed a multivariable Cox survival analysis to determine the effect of the burden of systolic and diastolic hypertension on a composite outcome of myocardial infarction, ischemic stroke, or hemorrhagic stroke over a period of 8 years. The analysis controlled for demographic characteristics and coexisting conditions. RESULTS The burdens of systolic and diastolic hypertension each independently predicted adverse outcomes. In survival models, a continuous burden of systolic hypertension (≥140 mm Hg; hazard ratio per unit increase in z score, 1.18; 95% confidence interval [CI], 1.17 to 1.18) and diastolic hypertension (≥90 mm Hg; hazard ratio per unit increase in z score, 1.06; 95% CI, 1.06 to 1.07) independently predicted the composite outcome. Similar results were observed with the lower threshold of hypertension (≥130/80 mm Hg) and with systolic and diastolic blood pressures used as predictors without hypertension thresholds. A J-curve relation between diastolic blood pressure and outcomes was seen that was explained at least in part by age and other covariates and by a higher effect of systolic hypertension among persons in the lowest quartile of diastolic blood pressure. CONCLUSIONS Although systolic blood-pressure elevation had a greater effect on outcomes, both systolic and diastolic hypertension independently influenced the risk of adverse cardiovascular events, regardless of the definition of hypertension (≥140/90 mm Hg or ≥130/80 mm Hg).

Cardiovascular morbidity of severe resistant hypertension among treated uncontrolled hypertensives: a 4-year follow-up study. J Hum Hypertens 2018; 32:487-493.

Abstract
Data regarding the prognosis of resistant hypertension (RHTN) with respect to its severity is limited. We investigated the cardiovascular risk of severe RHTN in a prospective observational study. A cohort of 1700 hypertensive patient with treated uncontrolled HTN was followed for a mean period of 3.6 ± 1.8 years. At baseline, standard clinical and laboratory workup was performed, including testing for secondary causes of RHT where applicable. Three groups were identified depending on presence of RHTN (office-based uncontrolled HTN under at least three drugs including a diuretic) and levels of office systolic blood pressure (BP): 1187 patients (70%) without RHTN, 313 (18%) with not-severe RHTN (systolic BP < 160 mmHg) and 200 (12%) with severe RHTN (systolic BP ≥ 160 mmHg). Endpoint of interest was cardiovascular morbidity set as the composite of coronary heart disease and stroke. During follow-up, incidence rates of cardiovascular events per 1000 person-years were 7.1 cases in the non-RHTN group, 12.4 cases in the not-severe RHTN group and 18 cases in the severe RHTN group. Unadjusted analysis showed that compared to uncontrolled patients without RHTN, patients with not-severe RHTN exhibited a similar risk but patients with severe RHTN had a significantly higher risk, by 2.5 times (CI: 1.28-4.73, p = 0.007). Even after multivariate adjustment for established risk factors including BP levels and isolated systolic HTN, severe RHTN remained as an independent predictor of the cardiovascular outcome (OR: 2.30, CI: 1.00-5.29, p = 0.05). In conclusion, among treated yet uncontrolled hypertensive patients, severe RHTN exhibits a significantly higher cardiovascular risk indicating the need for prompt management.

Abstract
Evidence has shown that long-term sodium reduction can not only reduce blood pressure, but also provide cardiovascular benefits. To date, there is little evidence related to the effects of salt reduction on isolated systolic hypertension (ISH).A total of 126 hypertensive patients were divided into an ISH group (n = 51) and a non-ISH (NISH) group (n = 75). The members of each group were then randomly assigned to low sodium salt (LSSalt) or normal salt (NSalt) diets for 6 months. Their blood pressure was measured every 2 months. Serum plasma renin-angiotensin activity, blood biochemical assays and urinary measurements were determined at the baseline and at the end of the 6 months.At the end of the study, the mean systolic blood pressure (SBP) of the ISH LSSalt group had significantly decreased by 10.18 mm Hg (95% confidence interval (CI): 3.13 to 17.2, P = .006) compared with that of the ISH NSalt group, while the mean SBP only decreased by 5.10 mm Hg (95% CI: -2.02 to 12.2, P = .158) in the NISH LSSalt group compared with that of the NISH NSalt group. The mean diastolic blood pressure (DBP) had no significant differences in the ISH and NISH groups. No obvious renin angiotensin system activation was found after LSSalt intervention. Regarding the urinary excretion of electrolytes and blood biochemical assays, the LSSalt treatment had the same effects on the ISH group as on the NISH group.The present study showed that the SBP of ISH patients was significantly decreased with the LSSalt intervention, while neither the SBP of the NISH patients nor the DBP of either group were similarly decreased, which indicated that ISH patients were more sensitive to salt restriction.

Abstract
The increase in pulse pressure (PP) that occurs with advancing age is predominantly due to reduced arterial distensibility leading to decreased aortic compliance, particularly in the elderly, in whom high blood pressure mainly manifests as isolated systolic hypertension. Since age-related changes in stroke volume are minimal compared with changes in PP, PP is often considered a surrogate measure of arterial stiffness. However, since PP is determined by both cardiac and arterial function, a more precise and reliable means of assessment of arterial stiffness is arterial pulse wave velocity (PWV), a parameter that is only dependent on arterial properties. Arterial stiffness as measured by PWV has been found to be a powerful pressure-related indicator for cardiovascular morbidity and mortality. We analyzed PP and PWV in men and women of various age groups in healthy volunteers as well as cardiac patients with different types of diseases. The findings identified several striking sex-specific differences which demand consideration in guidelines for diagnostic procedures, for epidemiological analysis, and in evaluation of therapeutic interventions.

Abstract
Prevalence of isolated systolic hypertension increases with age, due to progressive elevation of SBP, and is a major risk factor for cardiovascular morbidity and mortality. Extensive research has shown that lowering SBP improves cardiovascular outcomes in patients with isolated systolic hypertension, yet SBP control rates remain largely inadequate regardless of antihypertensive treatment. Arterial stiffness is a major determinant of elevated SBP resulting from structural changes in the vascular system, mediated by neurohormonal alterations that occur with vascular ageing. Clinical data have demonstrated an independent association between arterial stiffness and cardiovascular outcomes. Therefore, arterial stiffness has the potential to be an important therapeutic target in the management of isolated systolic hypertension. Current antihypertensive treatments have limited effects on arterial stiffness, so the development of new treatments addressing neurohormonal alterations central to vascular ageing is important. Such therapies may represent effective strategies in the future management of SBP.

Abstract
BACKGROUND We conducted this meta-analysis to systematically review and analyze the clinical benefits of angiotensin receptor blocker (ARB) combined with calcium channel blocker (CCB) following ineffective CCB monotherapy. METHODS PubMed was searched for articles published until August 2015. Randomized controlled trials (RCTs) evaluating the clinical benefits of ARB combined with CCB following ineffective CCB monotherapy were included. The primary efficacy endpoint of the studies was normal rate of blood pressure, the secondary efficacy endpoints were the response rate and change in blood pressure from baseline. The safety endpoint of the studies was incidence of adverse events. Differences are expressed as relative risks (RRs) with 95% confidence intervals (CIs) for dichotomous outcomes and weighted mean differences (WMDs) with 95% CIs for continuous outcomes. Heterogeneity across studies was tested by using the I(2) statistic. RESULTS Seven RCTs were included and had sample sizes ranging from 185 to 1,183 subjects (total: 3,909 subjects). The pooled analysis showed that the on-target rate of hypertension treatment was significantly higher in the amlodipine + ARB group than in the amlodipine monotherapy group (RR =1.59; 95% CI, 1.31-1.91; P<0.01). The response rate of systolic blood pressure (SBP) (RR =1.28; 95% CI, 1.04-1.58; P<0.01) and diastolic blood pressure (DBP) (RR =1.27; 95% CI, 1.12-1.44; P=0.04) were significantly higher in the amlodipine + ARB group than in the amlodipine monotherapy group. The change in SBP (RR =-3.56; 95% CI, -7.76-0.63; P=0.10) and DBP (RR =-3.03; 95% CI, -6.51-0.45; P=0.09) were higher in hypertensive patients receiving amlodipine + ARB but the difference did not reach statistical significance. ARB + amlodipine treatment carried a lower risk of adverse events relative to amlodipine monotherapy (RR =0.88; 95% CI, 0.80-0.96; P<0.01). CONCLUSIONS The results of our meta-analysis demonstrate that adding an ARB to CCB after initial ineffective CCB monotherapy, significantly improved blood pressure control and the percentage of on-target hypertension treatment with significantly reduced incidence of adverse events compared with continued CCB monotherapy.

Abstract
BACKGROUND This system review and meta-analysis was conducted to systematically review and analyze the clinical benefits of different antihypertensive agents in improving arterial stiffness in hypertensive patients. METHODS PubMed database was searched for randomized controlled trials (RCTs) evaluating the effects of angiotensin receptor blockers (ARB) or other types of antihypertensive agents on pulse wave velocity (PWV). The main indicators were the improvements of PWV and augmentation index (AI) before and after randomized treatments with antihypertensive agents. For the studies that only provided the mean and standard deviation of the indicators before and after randomization, the standardized mean difference (SMD) method was directly applied to combine the mean and standard deviation of various indicators after the treatment. For the studies provided the mean and standard deviation of the changes of the indicators, the weighted mean difference (MD) method was applied to combine the mean and standard deviation of the therapeutic effect. RESULTS Ten RCT studies were included and the sample sizes range from 40 to 201 (total: 938). Four studies provided the changes of PWV before and after randomization, the pooled analysis showed that the changes of PWV in ARB group were not significantly higher than other antihypertensive agents [MD: 125.76, 95% confidence interval (CI): -78.70 to 330.23, P=0.23]; 4 studies provided the PWV values before and after randomization, the PWV values in ARB group were not significantly superior (SMD: 0.04, 95% CI: -0.16 to 0.24, P=0.71). Three studies provided the changes of AI before and after randomization, the ability of ARB to lower the level of the AI was superior to other antihypertensive agents (MD: 8.94, 95% CI: 2.18-5.71, P=0.01); 2 studies provided the AI value after randomization, the abilities of ARB and other anti-hypertensive agents to improve the AI were similar (SMD: 0.03, 95% CI: -1.20 to 1.26, P=0.06). CONCLUSIONS The effect of ARB on the improvement of the PWV level is not superior to other types of antihypertensive agents, but ARB is superior to other types of antihypertensive agents for improving the AI level. Overall, to improve of arterial stiffness, ARB maybe is superior to other antihypertensive agents.

Abstract
PURPOSE Studies evaluating the response in blood pressure (BP) following high-intensity interval training (HIIT) are scant even though there has been extensive work done on the BP response following acute and chronic low- to moderate-intensity aerobic and resistance exercise in both hypertensive and normotensive individuals. The present study sought to investigate the training and detraining effects of short-term HIIT on the post-exercise hypotension (PEH) response in overweight/obese young women. METHOD Twenty young untrained women volunteered for the study. Participants performed six HIIT sessions on a treadmill within 2 weeks (week 1: 10 × 1 min and week 2: 15 × 1 min intervals at 90-95% HRmax, separated by 1 min active recovery at 70% HRmax each session) and detrained for 2 weeks. Post-exercise BP was measured for 1 h following the first and last HIIT sessions. RESULTS Participants were normotensive (SBP: 119.2 ± 5.60 mmHg; DBP: 78.8 ± 4.12 mmHg) and had a BMI greater than 25 kg m(-2). The magnitude of the systolic hypotensive response was slightly greater after the six sessions HIIT compared to pre-training (5.04 and 4.28 mmHg, respectively), and both would be considered clinically significant (>3 mmHg decrease). After 2 weeks, detraining the PEH response was not clinically significant (1.08 mmHg decrease). The magnitude of the DBP response was only clinically significant following post- and detraining (4.26 and 3.87 mmHg, respectively). CONCLUSION The findings suggest that six HIIT sessions is sufficient to affect clinically significant PEH responses in young, overweight/obese women; however, the training effects are lost within 2 weeks of detraining.

Abstract
The aim of this study was to test the association of peroxisome proliferator-activated receptor (PPAR-γ2) (Pro12Ala, C1431T) and β3-AR (Trp64Arg) polymorphisms with metabolic, nutritional, and blood pressure parameters in 271 postmenopausal women (151 hypertensive and 120 normotensive controls). The TaqMan genotyping assay and restriction fragment length polymorphism methods were used to determine the distributions of selected alleles and genotype frequencies. Nutritional status was determined by a bioimpedance method and dietary habits were assessed via 7-day dietary recall. The distribution of selected genotypes and allele frequencies did not differ between hypertensive women and normal controls after analysis by chi-square test. The postmenopausal hypertensive women were older and had higher body fat mass, serum glucose, and triglyceride levels. The cluster analysis showed that the hypertensive group with Pro12Pro genotype had highest pulse pressure and mean arterial pressure values when compared with Pro12Ala patients. In the logistic regression analysis, blood glucose (Pro12Ala polymorphism) and energy intake (C1431Tand T1431T polymorphisms) determined hypertension.

Abstract
Tyrosine kinase inhibitors (TKIs) have contributed to marked improvements in survival in patients with chronic myeloid leukaemia (CML). This article discusses the place of the second-generation TKIs dasatinib and nilotinib in the first-line treatment of CML and is based on published literature. The new agents are more potent and effective than imatinib. Data from pivotal clinical trials indicate that response to dasatinib and nilotinib is greater and more rapid than that to imatinib, resulting in a higher probability of patients achieving an optimal response to treatment. Differences between the newer agents with respect to patient groups for whom caution is advised, drug interaction potential, haematological toxicity, pulmonary toxicity, changes in the immune system and effects on laboratory parameters are discussed. With similar levels of efficacy, the choice of second-generation agents should be guided by the characteristics of the individual patient and the most suitable dosing regimen.

Abstract
BACKGROUND Hypertension and dyslipidemia have traditionally been associated with dietary sodium and fat intakes, respectively; however, they have recently been associated with the consumption of added sugars in adults and older adolescents, but there is no clear indication of how early in the life span this association manifests. OBJECTIVE This study explored the cross-sectional association between added sugar (sugars not naturally occurring in foods) consumption in children, blood pressure (BP), and fasting blood lipids [triglycerides and total, low-density lipoprotein, and high-density lipoprotein (HDL) cholesterol]. DESIGN BP, blood lipids, and dietary intakes were obtained in a multiethnic pediatric sample aged 7-12 y of 122 European American (EA), 106 African American (AA), 84 Hispanic American (HA), and 8 mixed-race children participating in the Admixture Mapping of Ethnic and Racial Insulin Complex Outcomes (AMERICO) study-a cross-sectional study conducted in the Birmingham, AL, metro area investigating the effects of racial-ethnic differences on metabolic and health outcomes. Multiple regression analyses were performed to evaluate the relations of added sugars and sodium intakes with BP and of added sugars and dietary fat intakes with blood lipids. Models were controlled for sex, race-ethnicity, socioeconomic status, Tanner pubertal status, percentage body fat, physical activity, and total energy intake. RESULTS Added sugars were positively associated with diastolic BP (P = 0.0462, β = 0.0206) and serum triglycerides (P = 0.0206, β = 0.1090). Sodium was not significantly associated with either measure of BP nor was dietary fat with blood lipids. HA children had higher triglycerides but lower added sugar consumption than did either the AA or EA children. The AA participants had higher BP and HDL but lower triglycerides than did either the EA or HA children. CONCLUSIONS These data suggest that increased consumption of added sugars may be associated with adverse cardiovascular health factors in children, specifically elevated diastolic BP and triglycerides. Identification of dietary factors influencing cardiovascular health during childhood could serve as a tool to reduce cardiovascular disease risk. This trial was registered at clinicaltrials.gov as NCT00726778.

Abstract
Objective. Patients with hypertension show deficits in cognitive function. However, the neural mechanisms underlying the preattentive information processing in hypertensive patients are poorly understood. We seek to investigate whether hypertensive patients have impairments in preattentive information processing. Methods. We compared visual mismatch negativity (vMMN) between 15 hypertensive patients and 15 age-matched healthy controls, which was elicited by the change of visual duration randomly presented in both peripheral visual fields. In addition, the global cognitive function for all participants was assessed with Mini-Mental State Examination (MMSE). Results. The vMMN in deviant-standard comparison was observed at occipital-temporal regions. Compared with normal healthy controls, the amplitude of vMMN was significantly decreased in hypertensive patients (P < 0.05). Meanwhile, the vMMN peak latency was delayed in the hypertensive group (P < 0.05). However, the MMSE scores of patients with hypertension were not significantly different from those of controls (P > 0.05), and there was no significant correlation between the mean amplitude of vMMN and SBP, DBP, and MMSE in hypertensive individuals, respectively. Conclusions. These data indicate dysfunction of automatically change detection processing in patients with hypertension. Moreover, the changes of vMMN provide a more objective and reliable assessment for cognitive impairment in hypertensive patients.

Abstract
OBJECTIVE To assess the dietary pattern associated with hypertension and pre-hypertension among Korean male and female adults. DESIGN Cross-sectional study from a representative sample of the Korean population. SETTING The Korea National Health and Nutrition Examination Survey IV, which was conducted in 2007 and 2008. SUBJECTS Males and females (n 5308) over the age of 20 years. RESULTS Scores for three major dietary patterns ('whole food', 'Western' and 'drinking') were generated using a factor analysis of thirty predefined food groups based on the food items consumed. We used polytomous logistic regression analyses to obtain odds ratios and 95% confidence intervals for pre-hypertension and hypertension. Participants with a high drinking pattern score (moderate to high alcohol intake, salted fermented seafood intake) had a significantly higher prevalence of pre-hypertension or hypertension than those with a lower drinking pattern score; odds for the top quintile v. the bottom quintile were OR = 1·56 (95% CI 1·23, 1·99; P trend = 0·001) for pre-hypertension and OR = 3·05 (95% CI 2·12, 4·40; P trend < 0·001) for hypertension. The whole food pattern was not associated with either pre-hypertension or hypertension, while the Western pattern was associated with the prevalence of hypertension only among men. CONCLUSIONS Our finding warrants further prospective studies to examine whether alcohol drinking and salty food consumption increase the risk of developing hypertension in Koreans.

Abstract
Findings of previous studies demonstrated that rs6007897 (C→T, Ala2268Thr) of the cadherin, epidermal growth factor (EGF) laminin A G-type repeats (LAG) seven-pass G-type receptor 1 gene (CELSR1) and rs9846911 (A→G) at chromosome 3q28 were significantly associated with ischemic stroke and chronic kidney disease, respectively. Given that hypertension is a risk factor for both ischemic stroke and chronic kidney disease, it was hypothesized that the association of rs6007897 with ischemic stroke or of rs9846911 with chronic kidney disease might be attributable, at least in part, to their effects on genetic susceptibility to hypertension. The purpose of the present study was to examine a possible association of rs6007897 of CELSR1 or rs9846911 at 3q28 with hypertension in community-dwelling individuals. Study subjects comprised 5,959 community-dwelling individuals (1,670 subjects with hypertension and 4,289 controls) who were recruited to a population-based cohort study. Comparisons of allele frequencies by the Chi-square test revealed that rs6007897 of CELSR1 (P=0.0280) and rs9846911 at 3q28 (P=0.0171) were significantly associated with the prevalence of hypertension. Multivariate logistic regression analysis with adjustment for age, gender, body mass index (BMI), smoking status, the serum concentration of creatinine and the prevalence of dyslipidemia and diabetes mellitus revealed that rs6007897 (P=0.0308; recessive model; odds ratio, 1.56) and rs9846911 (P=0.0353; dominant model; odds ratio, 1.22) were significantly associated with hypertension with the T allele rs6007897 and the G allele rs984691 representing risk factors for this condition. CELSR1 and 3q28 may thus be susceptibility loci for hypertension.

Abstract
Idiopathic normal pressure hydrocephalus (INPH) is a syndrome of ventriculomegaly, gait impairment, cognitive decline and incontinence that occurs in an elderly population prone to many types of comorbidities. Identification of the comorbidities is thus an important part of the clinical management of INPH patients. In 2011, a task force was appointed by the International Society for Hydrocephalus and Cerebrospinal Fluid Disorders (ISHCSF) with the objective to compile an evidence-based expert analysis of what we know and what we need to know regarding comorbidities in INPH. This article is the final report of the task force. The expert panel conducted a comprehensive review of the literature. After weighing the evidence, the various proposals were discussed and the final document was approved by all the task force members and represents a consensus of expert opinions. Recommendations regarding the following topics are given: I. Musculoskeletal conditions; II. Urinary problems; III. Vascular disease including risk factors, Binswanger disease, and white matter hyperintensities; IV. Mild cognitive impairment and Alzheimer disease including biopsies; V. Other dementias (frontotemporal dementia, Lewy body, Parkinson); VI. Psychiatric and behavioral disorders; VII. Brain imaging; VIII. How to investigate and quantify. The task force concluded that comorbidity can be an important predictor of prognosis and post-operative outcome in INPH. Reported differences in outcomes among various INPH cohorts may be partly explained by variation in the rate and types of comorbidities at different hydrocephalus centers. Identification of comorbidities should thus be a central part of the clinical management of INPH where a detailed history, physical examination, and targeted investigations are the basis for diagnosis and grading. Future INPH research should focus on the contribution of comorbidity to overall morbidity, mortality and long-term outcomes.

Abstract
OBJECTIVE With the increasing prevalence of diseases related to obesity, metabolic syndrome and its key player adiponectin are now attracting considerable attention. Hypoadiponectinaemia is reported to be a risk factor for hypertension and associated with endothelial dysfunction, which is closely related to complications of obesity such as hypertension. As there is limited information regarding serum adiponectin levels in normotensive people, we undertook the large-scale study to determine the association of adiponectin with blood pressure (BP) in mainly normotensive people. DESIGN, PATIENTS AND MEASUREMENTS In 21 100 Japanese adults (12 363 men and 8737 women) who had no apparent diseases, we examined the relationship between the serum adiponectin concentration and BP by performing a questionnaire survey, physical measurements and measurement of laboratory parameters including the serum adiponectin level. RESULTS Subjects with hypoadiponectinaemia had higher systolic and diastolic BPs as already reported. And interestingly, subjects with higher adiponectin had lower systolic and diastolic BP. According to linear regression analysis, adiponectin showed a significant negative correlation with systolic and diastolic BP independently of the other variables. Analysis of covariance according to adiponectin quintiles showed that systolic and diastolic BP in highest adiponectin quintile was significantly lower than in other quintiles. CONCLUSIONS This study revealed that there were significant trends toward lower systolic and diastolic BP with higher adiponectin not only in hypertensive people but also in normotensive people.

Abstract
It is well known that blood pressure (BP) management reduces the incidence of cerebrovascular and cardiovascular events. However, it is unclear how many of these events occur in hypertensive patients who receive pharmacological treatment. The aim of this survey was to evaluate the occurrence rate of both types of events in patients receiving valsartan-based treatment. Of 30 366 patients treated with valsartan, 28 356 patients were observed for 2.93 years. Antihypertensive drugs other than valsartan were used in 56.8% of patients. After the administration of valsartan, the systolic and diastolic BP significantly decreased from 161.1±19.1/90.4±13.1 to 139.9±18.1/79.6±11.9 mm Hg. Cerebrovascular events were observed in 550 patients (1.94%, 9.29/1000 patient-years), and cardiac events were observed in 576 patients (2.03%, 9.73/1000 patient-years). A comparative analysis of the hazard ratios for cerebrovascular and cardiac events according to the BP level at the endpoint showed a BP-dependent reduction of risk for cerebrovascular events, and the change in risk exhibited a J-curve phenomenon in the relationship between cardiac events and systolic BP. The J-curve phenomenon was not observed in patients aged <75 years, but it was observed for the systolic BP in patients aged 75 years. Adverse drug reactions were observed in 1925 of 28 420 patients (6.77%). This post-marketing surveillance data for valsartan showed the outcomes for treated hypertensive patients in a large population in Japan who were followed for up to 3 years. These data will add important knowledge regarding the treatment of hypertension in Japan.

Abstract
Background The role of hypertension in the loss of cognitive function is controversial. Relationships between hypertension and increases in cerebral vascular resistance, diffused lesions and multiple lacunar infarcts of the white matter are well known. Thus, the objectives of this study were: to evaluate the relationship between hypertension and cognitive dysfunction (CD), identify risk factors and determine the association between early markers of vascular disease and CD in hypertensive individuals. Methods Two hundred individuals aged between 40 and 80 years old were evaluated in this cross-sectional prospective study. Fifty participants were controls (CT). The remaining 150 hypertensive patients were subdivided into two groups, those with CD (HCD) and those without CD (HNCD). All participants underwent clinical evaluations and biochemical blood tests were performed. CD was investigated using the Mini Mental State Examination (MMSE) following the guidelines for its use in Brazil. The impact of hypertension on the arterial bed was assessed by identifying and measuring changes in the intima-media thickness (IMT) by vascular ultrasonography of the carotid arteries and analyses of the central blood pressure and Augmentation Index by applanation tonometry of the radial artery. Results There were no significant differences in the total cholesterol, high-density lipoprotein cholesterol and triglycerides plasma concentrations between the three groups. The serum creatinine and estimated glomerular filtration rate were within normal ranges for all three groups. A significantly lower MMSE score was recorded for the HCD Group compared to the HNCD and CT Groups (p-value < 0.05). The IMT was significantly different between the HNCD and HCD Groups (p-value = 0.0124). A significant difference in the IMT was also observed between hypertensive patients and the CT Group (p-value < 0.0001). Age, low-density cholesterol, high-density cholesterol, triglycerides and IMT increased the Odds Ratio for cognitive dysfunction. The central systolic pressure was significantly higher in the HCD and HNCD Groups compared to CT Group (p-value < 0.0001). Conclusions Hypertensive patients with CD have changes in the vascular morphology characterized by an increased carotid IMT, enhanced atherosclerotic lipid profile and impaired hemodynamic functional manifested by elevated central systolic blood pressure.

Abstract
The purpose of this investigation was to examine the associations between circulating markers of inflammation and arterial elasticity in healthy older women. Participants were 50 women older than 60 years of age, body mass index 27 ± 4, and physically untrained. Large artery elasticity, small artery elasticity, systemic vascular resistance, total vascular impedance, estimated cardiac output, and estimated cardiac index were determined using pulse contour analysis. Serum concentrations of tumor necrosis factor-α, C-reactive protein (CRP), and interleukin 6 were assessed. Results from Pearson's correlation revealed that tumor necrosis factor-α was inversely associated with large artery elasticity (-.426, p < .01) and estimated cardiac index (-.324, p < .05) and positively associated with systemic vascular resistance (.386, p < .01) and total vascular impedance (.416, p < .01). Additionally, C-reactive protein was inversely associated with large artery elasticity (-.308, p < .01). The overall implication was that tumor necrosis factor-α and C-reactive protein appear to be critical inflammatory cytokines associated with reductions in arterial elasticity in older women.

Hypertension is one of the modifiable risk factors for stroke. Lowering blood pressure is helpful for primary and secondary prevention of stroke. This study is aimed to assess the efficacy of Chunghyul-dan on stroke patients with stage 1 hypertension using 24 hours ambulatory blood pressure monitoring (24ABPM). Forty hospitalized stroke patients with stage 1 hypertension were included in the study and they were randomly assigned into two groups: group A was treated with Chunghyul-dan 1200 mg once a day for 2 weeks, while group B was not. Twelve subjects were dropped out because of unexpected early discharge or data errors, thus the remaining 28 subjects were included in the final analysis (15 in group A and 13 in group B). Blood pressure was monitored every 30 minutes for 24 hours at baseline and 2 weeks after medication. Blood pressure, pulse rate, trough/peak ratio (TPR) [the value calculated by dividing the blood pressure change at trough (22 to 24 hours after drug intake) by the change at peak (2 adjacent hours with a maximal blood pressure reduction between the second and eighth hour after drug intake)] and smoothness index (SI) (the value calculated as the ratio between the average of the 24 hours, treatment-induced blood pressure changes and its standard deviation) were compared to assess the efficacy of Chunghyul-dan. To assess the safety of Chunghyul-dan, any adverse effects during medication period were monitored. There was no significant difference in the baseline assessment between the two groups. Systolic blood pressure was lower in group A than in group B (141.37 ± 8.96 mmHg versus 132.28 ± 9.46 mmHg , P = 0.03), while diastolic blood pressure and pulse rate had no significant difference between the two groups. Systolic TPR and SI was 0.87 and 1.04 in group A, respectively. This suggests that Chunghyul-dan have anti-hypertensive effect on stroke patients with stage 1 hypertension.

The Association between Hypertension and Dementia in the Elderly. Int J Hypertens 2011; 2012:320648.

Abstract
Hypertension (HT) and dementia are common disorders in the elderly. HT in the elderly is associated with increased occurrence rates of dementia including Alzheimer's disease (AD) and vascular dementia (VaD). In connection to this, some studies have suggested that HT in old age correlates with the pathogenesis of dementia. Since HT is potentially reversible, a number of randomized trials have examined whether antihypertensive treatment may help in preventing dementia occurrence. We review five studies, all using subjects 60 years or older, which investigated different antihypertensive pharmacological treatments. Data from two trials (Syst-Eur, PROGRESS) open the way toward the prevention of dementia (AD or VaD) by antihypertensive treatments. In the Syst-Eur study, with the dihydropyridine calcium antagonists, a reduction in both types of dementia was demonstrated (risk reduction 55%). The PROGRESS study showed that the use of angiotensin-converting enzyme inhibitors (ACEIs), with or without diuretics, resulted in decrease incidence of stroke-related dementia (risk reduction 19%), but dementia without stroke was not reduced. In contrast, the SHEP trial, treatment with a chlorthalidone-based antihypertensive regimen, did not significantly reduced the incidence of dementia. The SCOPE study (candesartan or hydrochlorothiazide versus placebo) and the HYVET-COG study (indapamide or perindopril versus placebo) found no significant difference between the active treatment and placebo group on the incidence of dementia. We found conflicting results regarding treatment benefits in dementia prevention. Recent clinical trials and studies on animal models suggest that blockades of RAS system could have reduced cognitive decline seen in Alzheimer's disease and vascular dementia. Future trials primarily designed to investigate the effects of antihypertensive agents on impaired cognition are needed.

Abstract
Hypertension is a widely prevalent and important risk factor for cardiovascular diseases that increase with aging. The hallmark of hypertension in the elderly is increased vascular dysfunction. However, the molecular mechanisms by which increased blood pressure leads to vascular injury and impaired endothelial function are not well defined. In the present paper, we will analyze several mechanisms described in the scientific literature involved in hypertension in the elderly as endothelial dysfunction, increased oxygen delivery to tissues, inflammation, cellular apoptosis, and increased concentration of active metabolites. Also, we will focus on new molecular mechanisms involved in hypertension such as telomeres shortening, progenitor cells, circulating microparticles, and epigenetic factors that have appeared as possible causes of hypertension in the elderly. These molecular mechanisms may elucidate different origin for hypertension in the elderly and provide us with new targets for hypertension treatment.

Abstract
OBJECTIVE Both higher socioeconomic status (SES) and supportive personal relationships confer health benefits, including better immune function. This study assessed the joint impact of SES and social support on the expression of a latent herpesvirus, Epstein-Barr virus (EBV), in a group of highly stressed women. METHODS Two-hundred and twenty four women either awaiting further evaluation following an abnormal mammogram or newly diagnosed with breast cancer completed questionnaires and provided blood samples to assess EBV viral capsid antigen (VCA) IgG antibody titers. RESULTS More highly educated women with more support from friends had lower EBV VCA antibody titers, reflecting a stronger cellular immune response to the latent virus; however, among less educated women, friend support was not associated with EBV antibody titers. As revealed in an ancillary analysis, more highly educated women with more friend support had lower systolic blood pressure (SBP); however, friend support was not associated with SBP among less educated women. Neither depression nor perceived stress mediated these associations. Neither cancer status nor cancer stage among those diagnosed with cancer was significantly related to these outcomes. CONCLUSION Lower SES women may not reap the same immunological benefits from friend support when experiencing a stressful life event as their higher SES counterparts.

Abstract
BACKGROUND We previously showed that the C→T polymorphism (rs6929846) in butyrophilin, subfamily 2, member A1 gene (BTN2A1) was associated with myocardial infarction in Japanese individuals. Given that hypertension is a major risk factor for myocardial infarction, the association of rs6929846 of BTN2A1 with myocardial infarction might be attributable, at least in part, to its effect on susceptibility to hypertension. We have thus examined the relation of rs6929846 of BTN2A1 to hypertension in Japanese individuals. METHODS A total of 8,567 Japanese individuals from two independent subject panels were examined: Subject panels A and B comprised 2,317 hypertensive individuals and 1,933 controls, and 2,911 hypertensive individuals and 1,406 controls, respectively. The genotype of rs6929846 was determined by a method that combines the PCR and sequence-specific oligonucleotide probes with suspension array technology. RESULTS Multivariable logistic regression analysis with adjustment for covariates revealed that rs6929846 of BTN2A1 was significantly associated with hypertension in subject panel A (P = 2.6 × 10(-6); odds ratio, 1.69) and in subject panel B (P = 0.0284; odds ratio, 1.24), with the T allele representing a risk factor for hypertension. The rs6929846 was associated with systolic blood pressure (BP) in subject panels A (P = 0.0063) and B (P = 0.0115) and with diastolic BP in subject panel B (P = 0.0323), with the T allele being related to high BP. CONCLUSIONS BTN2A1 may be a susceptibility gene for hypertension in Japanese individuals. Determination of genotype for this polymorphism may prove informative for assessment of the genetic risk for hypertension.

Abstract
Calcineurin inhibitor (CNI) withdrawal has been used as a strategy to improve renal allograft function. We previously reported that conversion from cyclosporine A (CsA) to sirolimus (SRL) 3 months after transplantation significantly improved renal function at 1 year. In the Postconcept trial, 77 patients in the SRL group and 85 in the CsA group were followed for 48 months. Renal function (Cockcroft and Gault) was significantly better at month 48 (M48) in the SRL group both in the intent-to-treat population (ITT): 62.6 mL/min/1.73 m(2) versus 57.1 mL/min/1.73 m(2) (p = 0.013) and in the on-treatment population (OT): 67.5 mL/min/1.73 m(2) versus 57.4 mL/min/1.73 m(2) (p = 0.002). Two biopsy proven acute rejection episodes occurred after M12 in each group. Graft and patient survival were comparable (graft survival: 97.4 vs. 100%; patient survival: 97.4 vs. 97.6%, respectively). The incidence of new-onset diabetes was numerically increased in the SRL group (7 vs. 2). In OT, three cancers occurred in the SRL group versus nine in the CsA group and mean proteinuria was increased in the SRL group (0.42 ± 0.44 vs. 0.26 ± 0.37; p = 0.018). In summary, the renal benefits associated with conversion of CsA to SRL, at 3 months posttransplantation, in combination with MMF were maintained for 4 years posttransplantation.

Abstract
We are presenting a review of Isolated Systolic Hypertension (ISH) as a cardiovascular risk factor with emphasis on the perioperative period. Isolated systolic hypertension is associated with aging and is the most frequent subtype (65%) among patients with uncontrolled hypertension. ISH is strongly associated with increased risks of cardiac and cerebrovascular events exceeding those in comparably aged individuals with diastolic hypertension. Patients with ISH show an increase in left ventricular (LV) mass and an increase in the prevalence of left ventricular hypertrophy (LVH). These LV changes increase cardiovascular events and frequently lead to diastolic dysfunction (DD). Treatment to reduce elevated systolic blood pressure has been shown to reduce the risk of cardiovascular events. In the perioperative setting, essential hypertension has not been found to be a significant risk factor for cardiac complications. Most of the studies were based on the definition of essential hypertension and underpowered in sample size. The significance of perioperative ISH, however, is not well studied, partly due to its recognition only fairly recently as a cardiovascular risk factor in the non-surgical setting, and partly due to the evolving definition of ISH. Perioperative cardiac complications remain a significant problem to the healthcare system and to the patient. Although the incidence of perioperative cardiac complications is prominent in high-risk patients as defined by the Revised Cardiac Risk Index (RCRI), the bulk of the cardiac complications actually occur in low-risk group. Currently, little understanding exists on the occurrence of perioperative cardiac complications in low- risk patients. A factor such as ISH, with its known pathophysiological changes, is a potential perioperative risk factor. We believe ISH is an under-recognized perioperative risk factor and deserves further studying. Our research group has recently been funded by the Heart Stroke Foundation (HSF) to examine ISH as a perioperative risk factor (PROMISE Study).

Abstract
Chronic kidney disease is a leading global health problem with an increasing prevalence. Hypertension is present in most patients with chronic kidney disease, and hypertension-related nephrosclerosis is a top cause of progressive renal damage and end-stage renal disease. Systolic blood pressure (BP) and pulse pressure, together with nocturnal BP, are the most important factors favoring the progression of renal failure. Consequently, strict control of BP and other cardiovascular risk factors is required, including an adequate degree of suppression of the renin-angiotensin system in every patient.

Abstract
BACKGROUND Elevated neutrophil count, a marker of systemic inflammation, has been suggested as a prognostic marker of cardiovascular disease in postmenopausal women with hypertension. We tested the hypothesis that an association exists between elevated neutrophil count and increased arterial stiffness, as reflected by a wide pulse pressure (PP), in this population of women. We also tested PP as predictor of cardiovascular adverse events in this population. METHODS We analyzed data relating to 886 postmenopausal women with hypertension, consecutively enrolled in a prospective registry. Ambulatory blood pressure monitoring was carried out at entry in all the subjects. The median duration of follow-up was 7.4 years (range: 1-21 years). RESULTS There was a direct relationship between neutrophil count and 24-h ambulatory PP (P < 0.0001) and this association remained significant after adjusting for age, serum glucose, and left ventricular (LV) hypertrophy at electrocardiogram (ECG) (all P < 0.01). During follow-up there were 121 first-time major cardiovascular (CV) events. The rate (× 100 patient-years) of CV events was 1.02, 1.36, and 3.75, respectively in the three tertiles of the distribution of 24-h PP (P < 0.0001). In a multivariate analysis, 24-h ambulatory PP and neutrophil count were independent predictors of total CV events after adjusting for the influence of other risk markers. In particular, for each 10 mm Hg increase in 24-h PP, there was a 73% higher risk for total CV events (P = 0.015). Office-recorded PP did not achieve significance when forced in the same model. CONCLUSIONS Increased arterial stiffness, as reflected in high values of 24-h ambulatory PP, is an adverse prognostic marker in postmenopausal women with hypertension, possibly as an additional correlate of systemic inflammation.

Abstract
AIM Unrecognised and untreated hypertension can lead to significant morbidity and mortality over time. In a 2003 chart review, we found that our providers only recognised 15% of hypertensive blood pressure (BP). Our objective was to determine whether a simplified BP table improves the recognition of elevated BP in children. METHODS We developed a simplified BP table for children 3-18 years and posted it in provider work areas beginning August 2006. We reviewed a retrospective sample of well visits for children aged 3-18 years, with equal numbers by sex and year of age, presenting at a university-based paediatric clinic between January and August 2007. Visit notes for all children with elevated BP values ≥ 90th percentile were reviewed to identify whether the provider recognised that the BP was elevated. RESULTS In 493 well visits, 85 (17.2%) children had pre-hypertensive (90th to < 95th percentile) and 100 (20.3%) had hypertensive (≥ 95th percentile) BP values. Providers recognised elevations in 34 (40%) pre-hypertensive and 77 (77%) hypertensive measurements. Recognition was significantly more common for those in the hypertensive than the pre-hypertensive range (χ² = 24.9, degrees of freedom= 1, P < 0.001). Compared with our 2003 data, recognition of hypertensive BP values was significantly greater (77% vs. 15%) (t = 14.479, degrees of freedom = 98, P <0.001) after introduction of the simplified BP table. CONCLUSIONS Use of a simplified BP table can lead to significantly improved recognition of elevated BP in children.

Abstract
Hypertension (especially systolic hypertension) is very common in older persons. Systolic hypertension occurs because large conduit arteries become stiffer with age. Strong evidence from randomized trials suggests that treating systolic blood pressures initially higher than 160 mm Hg is extremely beneficial, and a recent trial extended this conclusion to healthy persons over 80 years of age. However, the only trial that has directly tested the use of more aggressive treatment goals (< 140 mm Hg) in the elderly did not show benefit in those older than 75. Risks of overtreating hypertension for the elderly include falls and orthostatic hypotension, and the most compromised older persons may be the most likely to experience adverse effects. Our current state of knowledge requires clinical judgment that balances the immediacy of adverse effects versus the potential but unproven benefits of treatment in deciding whether to treat the elderly more aggressively than the goals used in randomized trials.

Abstract
Racism and discrimination can have significant implications for health, through complex biopsychosocial interactions. Latino groups, and particularly Puerto Ricans, are an understudied population in the United States in terms of the prevalence of discrimination and its relevance to health. Participants in our study were 45- to 75-year-old (N = 1122) Puerto Ricans. The measures were perceived discrimination, depressive symptomatology (CES-D), perceived stress (PSS), self-rated health, medical conditions, blood pressure, smoking and drinking behaviours, demographics. Our findings show that 36.9 per cent of participants had at some time experienced discrimination, with men, those with more years of education, currently employed and with higher incomes being more likely to report it. Experiences of discrimination were associated with increased levels of depressive symptoms and perceived stress. When controlling for covariates, perceived discrimination was predictive of the number of medical conditions, of ever having smoked and having been a drinker, and having higher values of diastolic pressure. Depressive symptoms are a mediator of the effect of perceived discrimination on medical conditions, confirmed by the Sobel test: z = 3.57, p < 0.001. Mediating roles of perceived stress, smoking and drinking behaviours were not confirmed. Increased depressive symptoms might be the main pathway through which perceived discrimination is associated with a greater number of medical diagnoses.

Abstract
In this prospective, randomized, open-label, blinded end point study, we aimed to establish whether strict blood pressure control (<140 mm Hg) is superior to moderate blood pressure control (> or =140 mm Hg to <150 mm Hg) in reducing cardiovascular mortality and morbidity in elderly patients with isolated systolic hypertension. We divided 3260 patients aged 70 to 84 years with isolated systolic hypertension (sitting blood pressure 160 to 199 mm Hg) into 2 groups, according to strict or moderate blood pressure treatment. A composite of cardiovascular events was evaluated for > or =2 years. The strict control (1545 patients) and moderate control (1534 patients) groups were well matched (mean age: 76.1 years; mean blood pressure: 169.5/81.5 mm Hg). Median follow-up was 3.07 years. At 3 years, blood pressure reached 136.6/74.8 mm Hg and 142.0/76.5 mm Hg, respectively. The blood pressure difference between the 2 groups was 5.4/1.7 mm Hg. The overall rate of the primary composite end point was 10.6 per 1000 patient-years in the strict control group and 12.0 per 1000 patient-years in the moderate control group (hazard ratio: 0.89; [95% CI: 0.60 to 1.34]; P=0.38). In summary, blood pressure targets of <140 mm Hg are safely achievable in relatively healthy patients > or = 70 years of age with isolated systolic hypertension, although our trial was underpowered to definitively determine whether strict control was superior to less stringent blood pressure targets.

Abstract
Cistus ladaniferus L. (Cistaceae) is a medicinal plant originated from the Mediterranean region which exerts different pharmacological effects. In the present study, our goal was to examine whether the plant possessed antihypertensive properties. Aqueous extract of Cistus leaves (AEC, 500mg/kg/day) reduced systemic blood pressure (SBP) in two animal models of hypertension, the l-NAME and renovascular two kidney-one clip (2K-1C) hypertensive rats. In the former, AEC prevented the increase in SBP when co-administered with l-NAME during four weeks (164+/-3mm Hg in l-NAME vs. 146+/-1mm Hg in l-NAME+AEC, p<0.001). In the latter, AEC reversed the increase in SBP when administered during four weeks after installation of the hypertension (146+/-5mm Hg with AEC vs. 179+/-6mm Hg without, p<0.05). AEC treatment also reversed the endothelial dysfunction observed in both animal models of hypertension. A direct effect on cardiac and vascular tissue was also tested by examining the contractile effects of AEC in rat isolated aortic rings and Langendorff perfused hearts. AEC (10mg/L) had no effect on left ventricular developed pressure and heart rate in isolated perfused heart. However, AEC produced a strong relaxation of pre-contracted rat aortic rings (80+/-2% relaxation, n=25). When the rings were denuded from endothelium or were incubated with 1mM Nomega-nitro-l-arginine (l-NNA), the relaxant effect of AEC was lost. We conclude that C. ladaniferus possesses antihypertensive properties which are mainly due to an endothelium-dependent vasodilatory action.

Abstract
The efficacy and safety of the angiotensin receptor blocker olmesartan medoxomil (OLM) was assessed in 550 elderly Japanese hypertensive patients who were followed for 24 weeks in daily clinical practice. Patients were given OLM alone or in combination with other antihypertensive drugs at the discretion of the investigators. After 24 weeks of treatment, systolic and diastolic blood pressure (BP) significantly decreased from baseline (P<.0001). When patients were classified as either young-old (65-74 years) or older-old (75 years and older), with either isolated systolic hypertension (ISH) or systolic-diastolic hypertension (SDH), the reduction of diastolic BP in ISH patients was significantly smaller than that in SDH patients (5.0 vs 15.2 mm Hg; P<.0001), indicating that OLM did not cause excessive reduction of diastolic BP in ISH patients. Treatment was well tolerated in all groups. In conclusion, the medication was safe and effective in reducing BP levels in ISH patients aged 75 years and older, as well as in other elderly hypertensive patients.

Abstract
AIMS AND OBJECTIVES We aimed to investigate age and gender differences in arterial stiffness, and whether this cardiovascular risk factor was detectable in healthy Caucasians before established disease was manifest. BACKGROUND A growing number of risk factors including diabetes, obesity, hypertension, hyperlipidaemia, smoking and age have been linked to the adverse cardiovascular end-points of myocardial infarction, stroke and heart failure. These risk factors lead to an increase in arterial stiffness. Measuring this stiffness at an early age may identify candidates for primary preventative intervention strategies by nurses. METHODS Caucasian Canadians (n = 176) were recruited. Peripheral and central blood pressure, pulse pressure, augmentation pressure, arterial compliance (augmentation index and pulse wave velocity) and sub-endocardial viability ratio (SEVR), were assessed using applanation tonometry (SphygmoCor system). Blood was drawn for fasting lipid and glucose profiling. RESULTS Women participants had significantly stiffer arteries than men (augmentation index: 28 SEM = 1% vs. 18 SEM = 2% respectively; p < 0.001). Pulse wave velocity, however, was not different (7.7 SEM = 0.2 m/s vs. 8.3 SEM = 0.1 m/s respectively; p < 0.001). Age was a strong predictor of arterial stiffening in both genders, but the effect was greater in women. CONCLUSIONS Women having stiffer arteries than men, thus at greater cardiovascular risk, may require earlier screening. The effect might be postmenopausal, and mechanisms require further investigation. However, both middle-aged men and women considering themselves 'healthy' may benefit from more proactive primary prevention. RELEVANCE TO CLINICAL PRACTICE Applanation tonometry, used extensively by nurses, provides early detection of central haemodynamic changes and vascular compliance at all ages. Knowledge of arterial stiffness could guide the management of primary prevention in the nursing cardiovascular risk reduction clinic.

Abstract
The clinical syndrome of sepsis encompasses a highly heterogeneous group of clinical disorders, varying with respect to the site, bacteriology, and even presence of infection and with the clinical syndrome evolving in the host. Clinical trials of strategies to modulate the host response that mediates sepsis were first initiated 25 years ago. A continuing record of disappointment has characterized subsequent work, and only a single new therapy has been licensed for clinical use. Yet, these commercial disappointments obscure a vibrant body of new knowledge that has clarified the biology of the innate immune response whose deranged expression is responsible for sepsis and that has provided important new insights into the failings of the traditional model of clinical research in sepsis. This review highlights advances in basic biology and underlines insights from clinical research that may point to new and more effective ways of translating an understanding of innate immunity into effective treatments for a leading cause of global morbidity and mortality.

Abstract
BACKGROUND Cognitive function is impaired in elderly subjects, so the aim of the present study was to determine the role of arterial stiffness on cognitive function. METHODS AND RESULTS Cognitive function and arterial stiffness were assessed by the Mini-Mental State Examination (MMSE) and measurement of the brachial-ankle pulse wave velocity (PWV), respectively. The cross-sectional association of the MMSE score and PWV was studied in 203 subjects (87 men, 116 women), all of whom were 85 years old. Sex distribution, systolic and diastolic blood pressures did not differ between the normal (MMSE score >or=24, n=128) and impaired MMSE groups (MMSE score <24, n=75). In contrast, the PWV was significantly increased in the impaired MMSE group than in the normal MMSE group (25.0+/-0.8 vs 22.9+/-0.5 m/s, p<0.05). In multiple regression analysis, the PWV was also independently and significantly associated with the MMSE score. CONCLUSIONS These results suggest that cognitive function could be predicted by arterial stiffness, as assessed by the PWV, in the very old. Preventing atherosclerosis may play an important role in preserving normal cognitive function until very old age.

Abstract
Telmisartan blocks the detrimental actions of angiotensin II mediated via the angiotensin type 1 receptor. Unique features of telmisartan are high lipophilicity and a long terminal elimination half-life (~ 24 h). Telmisartan/hydrochlorothiazide is indicated for hypertensive patients unable to achieve target blood pressure with either monotherapy. Fixed-dose combination tablets containing telmisartan 40 or 80 mg and hydrochlorothiazide 12.5 mg are widely available; in addition, telmisartan/hydrochlorothiazide 80/25 mg is available in the USA. Telmisartan/hydrochlorothiazide is superior to losartan/hydrochlorothiazide and valsartan/hydrochlorothiazide in maintaining blood pressure control in the risky early morning hours at the end of the dosing interval. Furthermore, telmisartan/ hydrochlorothiazide provides superior 24-h mean blood pressure reduction and is better tolerated than amlodipine/hydrochlorothiazide in elderly patients with predominantly systolic hypertension. Telmisartan has the potential to confer additional reno- and cardioprotection to that due to blood pressure control. The cardioprotective activity of renin–angiotensin system blockade with telmisartan alone and in combination with ramipril is currently being evaluated in the ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET) and the Telmisartan Randomized AssessmeNt Study in aCE iNtolerant subjects with cardiovascular Disease (TRANSCEND). In total, 31,546 patients have been enrolled worldwide and are being followed for up to 5.5 years.

Abstract
OBJECTIVE To provide global estimates of blood pressure by age and sex for adults aged > or = 30 years, by WHO subregion. DESIGN AND METHODS Data were obtained from studies identified in a literature review of population-based surveys. These were complemented by data from MONICA and INTERSALT studies. Estimates of the shape of the age-systolic blood pressure (SBP) association were made from survey data utilizing parametric and non-parametric analyses. A linear sex-specific association of SBP with age was demonstrated from 30 to 70 years in females and 20 to 70 years for males in each subregion. Mean age- and sex-specific estimates of SBP were estimated for each WHO subregion separately, based on study and country-weighted SBP data. RESULTS Analyses were based on data from about 230 surveys and over 660 000 participants. Age-specific mean SBP values ranged from 114 to 164 mmHg for females, and 117-153 mmHg for males. Females typically had lower SBP levels than males in the 30-44-year age groups, but in all subregions, SBP levels rose more steeply with age for females than males. Therefore, SBP levels in those aged > or = 60 years tended to be higher in females. Subregions with consistently high mean SBP levels included parts of eastern Europe and Africa. Mean SBP levels were lowest in south-east Asia and parts of the western Pacific. CONCLUSIONS These global estimates of blood pressure by age, sex and subregion show considerable variation in estimated levels. The lack of data in developing countries is substantial, and this is an important limitation given the role of blood pressure in increasing cardiovascular disease levels.
