Both the dopaminergic and renin-angiotensin systems play important roles in the regulation of blood pressure. Our previous study showed that the stimulation of dopaminergic D4 receptors reduced angiotensin II type 1 (AT1) receptor expression in renal proximal tubule (RPT) cells. In this study, we tested whether AT1 receptors, in return, would regulate D4 receptor expression and function in RPT cells. Expression of the D4 receptor from Wistar-Kyoto (WKY) or spontaneously hypertensive rats (SHRs) RPT cells and renal cortex tissues were determined by western blot, and Na(+)-K(+) ATPase activity was determined using an enzyme assay...

Both hypertension and diabetes in middle-aged individuals have been suggested to be predictive indicators of cognitive decline. However, the association of hypertension, diabetes and their combination with cognitive functioning is still controversial in older people. The purpose of this study was to investigate the association between cognitive decline and hypertension, diabetes, and their combination in 70-year-old people based on a 3-year longitudinal analysis. Four hundred and fifty-four people aged 70 (±1) years who participated in the Japanese longitudinal cohort study of Septuagenarians, Octogenarians and Nonagenarians Investigation with Centenarians (SONIC) were recruited randomly from a general population and were monitored for 3 years...

Serum uric acid (SUA) is correlated with an increased risk of not only gout but also cardiovascular diseases. The present study aimed to longitudinally evaluate the effects of SUA level on renal function and arterial stiffness in a population-based sample of normotensive subjects. The subjects completed a health checkup in 2002 at baseline and in 2011 or 2012 at the end of the follow-up period. A total of 407 normotensive subjects (171 men and 236 women) aged 26-66 years were enrolled in this study. We measured blood pressure (BP), brachial-ankle pulse wave velocity (baPWV), central BP, intima-media thickness, SUA level and estimated glomerular filtration rate (eGFR)...

Left ventricular hypertrophy (LVH) is a marker of prolonged exposure to high blood pressure and a predictor of cardiovascular disease risk. The objective of the current study was to investigate its association with cognitive function. Following standard guidelines, pairs of independent reviewers screened 2359 articles to search for studies that addressed the research question, extracted data and evaluated the quality of the studies using the Newcastle-Ottawa scale; authors were contacted for additional data...

The relationship between cardiorespiratory fitness and arterial compliance in children and adolescents remains controversial. The aim of this study was to assess this association with a quantitative approach. A total of 646 healthy children and adolescents (316 females, age 13.9±2.1 years) were cross-sectionally investigated in seven school settings in and around Munich for their cardiorespiratory fitness and demographic, anthropometric and hemodynamic parameters. Surrogates of arterial stiffness, such as pulse wave velocity (PWV), Augmentation Index normalized to a heart rate of 75 (AI@75), and peripheral and central systolic blood pressures were measured in a supine position using the oscillometric Mobil-O-Graph...

To prevent cardiovascular events in patients with diabetes mellitus (DM), it is essential to reduce arterial pressure (AP). Sodium-glucose cotransporter 2 inhibitor (SGLT2i) prevents cardiovascular events via the depressor response in patients with DM. In the present study, we examined whether SGLT2i ameliorates AP lability in DM rats. Ten-week-old male Sprague-Dawley rats were administered a single intravenous injection of streptozotocin (50 mg kg(-1)) and were divided into three groups treated with low-dose SGLT2i, vehicle (VEH) or subcutaneously implanted insulin pellets (SGLT2i, VEH and Insulin group, respectively) for 14 days...

Emotional distress has been associated with a poorer prognosis in myocardial infarction patients. Elevated adrenocorticotrophic hormone (ACTH), lower cortisol, dehydroepiandrosterone sulfate (DHEAS) and cortisol:DHEAS, as measures of emotional distress, might correlate with silent myocardial ischemia (SMI) and workload. Thus, we assessed the relationship between emotional distress, SMI and double product (systolic blood pressure (SBP) × heart rate). Cross-sectional South African biethnic single-set cohorts (N=378), aged 44...

Blood pressure (BP) variability and nocturnal decline in blood pressure are associated with cardiovascular outcomes. However, little is known about whether these indexes are associated with white-coat and masked hypertension. We performed a cross-sectional analysis of 1047 community-dwelling individuals aged ⩾60 years in Spain in 2012. Three observer-measured home BPs and 24-h ambulatory blood pressure monitoring (ABPM) were performed under standardized conditions. BP variability was defined as BP s.d. and coefficient of variation...

Abnormal autonomic nervous regulation has an important role in the development of hypertension. As to whether blood pressure (BP) or BP variability represents the proper characteristics for predisposition to hypertension in Chinese young adults remains controversial. We studied the properties of the indices extracted from beat-to-beat BP during a 13 min cold pressor test (CPT). In this study, 69 Chinese young adults including 34 offspring of hypertensive parents (OHPs; 25.6±2.5 years) and 35 offspring of normotensive parents (ONPs; 25...

Most guidelines for the management of hypertension define it as a home blood pressure (HBP) value >135/85 mm Hg. However, there is no reference HBP value to diagnose hypertension in pregnant women. Therefore, in this study, we analyzed HBP measurements of pregnant women to determine whether it is appropriate to use the criteria for non-pregnant subjects for pregnant women. The participants of this study were 100 singleton pregnant women who visited our hospital between September 2013 and September 2016...

Persistent pulmonary hypertension of the newborn (PPHN) is a clinical syndrome characterized by increased medial and adventitial thickness of the lung vasculature. The underlying mechanisms that regulate the cell phenotype alteration during PPHN remodeling are largely unknown. We randomly selected newborn rats that were exposed to hypoxia (10-12%) or room air for 2 weeks and used a microarray to identify the lung tissue microRNAs (miRNAs) involved in PPHN progression. The role of a key miRNA that affects the endothelial-to-mesenchymal transition (EndMT) in primary cultured rat pulmonary microvascular endothelial cells (RPMECs) was investigated...

Although hypertension is a clear risk factor for cardiovascular disease, how prehypertension and controlled hypertension influence left ventricular (LV) diastolic function and structure remain to be elucidated. Thus, this study was intended to investigate the link between LV diastolic dysfunction and structural changes in different categories of hypertension. A cohort of 52 111 Korean adults receiving echocardiograms was enrolled. The study population was stratified into five groups according to the following categories of hypertension and blood pressure (BP): normotensive (<120/80 mm Hg), prehypertensive (120-139/80-89 mm Hg), controlled hypertensive (<140/90 mm Hg), newly recognized hypertensive and uncontrolled hypertensive (⩾140/90 mm Hg)...

Pressure overload-induced left ventricular myocardial hypertrophy (LVH) is characterized by increased proarrhythmic vulnerability. In contrast, pressure unloading leads to reverse remodeling and decreases LVH-associated arrhythmogenicity. However, cellular changes that occur during reverse electrical remodeling have been studied less. Therefore, we aimed to provide an electrocardiographic characterization of a rat model of LVH that underwent pressure unloading and to simultaneously identify the underlying cellular and functional alterations...
