During blood pressure (BP) measurement, the recommended positioning of the cuff bladder center is directly above the brachial artery. We investigated the relevance of incorrect cuff positioning during (1) auscultatory measurement with an appropriate or improperly small cuff and (2) oscillometric measurement with a wide-range cuff designed to guarantee accurate measurements regardless of position. In subjects with wide BP and arm circumference ranges, (1) auscultatory BP was repeatedly measured with a properly positioned cuff (reference) and, simultaneously, with an identical cuff placed on the other arm in either a correct or an incorrect position (test)...

The early arterial dysfunction linked with obesity and a sedentary lifestyle heightens the likelihood of suffering from future cardiovascular events. Whole-body vibration training (WBVT) may improve systemic arterial stiffness (brachial-ankle pulse wave velocity (baPWV)) and muscle strength in pre- and post-menopausal women. However, the effectiveness of WBVT to impact the arterial segments included in baPWV is unknown. The aim of this study was to investigate the effects of WBVT on aortic and leg arterial stiffness in young sedentary overweight/obese women...

Few studies have focused on the effect of organ damage on achievement of long-term home blood pressure (BP) control. Based on the nationwide home BP-based trial data, we aimed to investigate the factors associated with home BP control, in particular, left ventricular hypertrophy (LVH) using the electrocardiogram in patients who started antihypertensive drug treatment. According to the trial protocol, we defined BP as controlled when systolic home BP reached specified targets (125-134 mm Hg in usual control (UC), n=1261; <125 mm Hg in tight control (TC), n=1288)...

The US Fourth Report (2004) recommended that elevated blood pressure (BP) on at least three occasions should be used to define hypertension in children and adolescents. However, there is no sufficient evidence to support this decision. This study aimed to assess the change in the prevalence of elevated BP obtained on three separate visits in children and adolescents worldwide using a meta-analysis. The PubMed database was searched for eligible studies published in English until 20 April 2016. Included studies were population based and reported on the prevalence of elevated BP measured on two or three separate occasions in pediatric populations...

High blood pressure levels are among the most important cardiovascular disease risk factors and are influenced by physical fitness and body composition. However, the degree to which obesity may attenuate or modify the beneficial effects of physical fitness on blood pressure levels in young adults is uncertain. Thus, the aim of this study was to analyze whether body composition is a mediator between cardiorespiratory fitness (CRF) and blood pressure levels in young adults. This work was a cross-sectional study involving first-year college students (n=386) at the University Campus of Cuenca (Spain)...

The endothelial nitric oxide (NO) system may be damaged in preeclampsia; however, the involved mechanisms are unclear. In this study, we used primary human umbilical vein endothelial cells (HUVECs) to evaluate the endothelial NO system in preeclampsia and to determine the underlying mechanisms that are involved. We isolated and cultured HUVECs from normal and preeclamptic pregnancies and evaluated endothelial NO synthase enzyme (eNOS) expression and NO production. Whole-cell K(+) currents and oxidative stress were also determined in normal and preeclamptic HUVECs...

Inter-arm systolic blood pressure (BP) differences (sIADs) have recently been recognized as a risk factor for cardiovascular mortality. However, sIAD reproducibility remains unresolved from a controlled trial perspective. We evaluated the between-visit reproducibility of sIADs in hypertensive patients. We examined 1875 hypertensive participants aged 20 years and older (mean age: 62.3 years, 45.4% female) from nine primary clinics and 27 secondary and tertiary hospitals. The BPs in both arms were automatically and simultaneously measured in triplicate with a cuff-oscillometric BP device...

Heart failure with preserved ejection fraction (HFpEF), which is a primary driver of morbidity and mortality, accounts for approximately half of all heart failure cases. Therefore, it is essential to develop preclinical animal models for HFpEF pharmacological treatment strategies. We created a porcine model of severe hypertension and hyperlipidemia by using a combination of deoxycorticosterone acetate (DOCA, 100 mg kg(-1)), Western diet (WD) and angiotensin II infusion. Systolic blood pressure, echocardiography and invasive pressure-volume loop were assessed at baseline, 12 weeks and 18 weeks...

The etiopathogenesis of cardiovascular diseases (CVDs) is multifactorial. Adverse blood pressure (BP) is a major independent risk factor for epidemic CVD affecting ~40% of the adult population worldwide and resulting in significant morbidity and mortality. Metabolic phenotyping of biological fluids has proven its application in characterizing low-molecular-weight metabolites providing novel insights into gene-environmental-gut microbiome interaction in relation to a disease state. In this review, we synthesize key results from the INTERnational study of MAcro/micronutrients and blood Pressure (INTERMAP) Study, a cross-sectional epidemiologic study of 4680 men and women aged 40-59 years from Japan, the People's Republic of China, the United Kingdom and the United States...

Although active smoking is linked with hypertension, the effect of environmental tobacco smoke exposure on hypertension has rarely been studied, and the scant epidemiological data available have yielded uncertain findings. Therefore, we conducted a cross-sectional study in a representative urban area of Beijing, China. A two-stage stratified clustering sampling method was performed, and 1078 female participants aged ⩾60 years were included in the analysis. Among the participants without antihypertensive treatment, >2 hours of daily passive cigarette smoking was significantly associated with higher systolic (by 4...

This meta-analysis aimed to investigate the predictive effect of copeptin as a biomarker for the prognosis of acute ischemic stroke and transient ischemic attack. Electronic databases including PubMed, Medline, EMBASE, Web of Science and Cochrane Central were searched for studies assessing the association of copeptin level on admission with prognosis of acute ischemic stroke and transient ischemic attack. The Newcastle-Ottawa Quality assessment scale for cohort study was used to evaluate quality. A total of 1976 acute ischemic stroke patients from 6 studies were included, and 59% of patients were male...

We compared three benidipine-based regimens-that is, benidipine plus angiotensin receptor blocker (ARB), β-blocker (BB) or thiazide-and found that the benidipine-BB combination was less beneficial in reducing the risk of stroke than the benidipine-thiazide combination. This sub-analysis sought to compare the effects of reaching a target blood pressure (BP) (<140/90 mm Hg) on the cardiovascular outcomes among the three benidipine-based treatment groups in the Combination Therapy of Hypertension to Prevent Cardiovascular Events trial...

The incidence of cardiovascular disease and mortality rates are high among patients with left ventricular hypertrophy (LVH). Obstructive sleep apnea (OSA) has been reported to increase left ventricular mass (LVM) and cause LVH. The prevalence of hypertension, a major cause of increased LVM, is high in OSA; however, it is still unknown whether OSA is an independent factor that increases LVM in addition to triggering LVH. This study investigated out-of-office blood pressure (BP) via ambulatory BP monitoring (ABPM) in patients with OSA diagnosed by polysomnography (PSG) and sought to determine the effects of OSA and hypertension on LVM...

REVIEW
Naro Ohashi, Shinsuke Isobe, Sayaka Ishigaki, Hideo Yasuda
Activation of the intrarenal renin-angiotensin system (RAS) has a critical role in the pathophysiology of the circadian rhythm of blood pressure (BP) and renal injury, independent of circulating RAS. Although it is clear that the circulating RAS has a circadian rhythm, reports of a circadian rhythm in tissue-specific RAS are limited. Clinical studies evaluating intrarenal RAS activity by urinary angiotensinogen (AGT) levels have indicated that urinary AGT levels were equally low during both the daytime and nighttime in individuals without chronic kidney disease (CKD) and that urinary AGT levels were higher during the daytime than at nighttime in patients with CKD...
