The pathophysiology and treatment of acute decompensated heart failure (HF) in the presence of chronic kidney disease (CKD) remain ill defined. Here we compared the prognostic factors for 1-year mortality in patients with acute HF with and without CKD. We retrospectively studied 392 consecutive patients with acute decompensated HF. CKD as a comorbidity in these patients was defined by an estimated glomerular filtration rate of <60 mL/min/1.73 m2 . Potential risk factors for 1-year mortality were selected by univariate analyses; then multivariate Cox regression analysis with forward selection (likelihood ratio) was performed to identify significant factors...

Oxidative stress is involved in the pathogenesis of hypertension and hypertensive organ damage. Our previous study suggested that stroke-prone spontaneously hypertensive rats (SHRSP) exhibited greater oxidative stress than SHR and that the stroke incidence was significantly greater in SHRSP than SHR. Therefore, we hypothesized that oxidative stress was responsible for the stroke susceptibility in SHRSP. The present study constructed Prdx2 (a gene coding an antioxidative enzyme)-knockout (KO) SHR to examine whether Prdx2 knockout would make SHR more vulnerable to hypertensive organ damage, including stroke...

Alterations of sympathoadrenal and sympathoneural systems have been suggested to be involved in the pathogenesis of hypertension in spontaneously hypertensive rats (SHR). To evaluate the ontogenetic changes of these systems, mRNA and protein expressions of catecholaminergic system genes were measured in adrenal glands and sympathetic ganglia, and the catecholamine levels were determined in adrenal glands, sympathetic ganglia and plasma of prehypertensive (4-week-old) and hypertensive (24-week-old) SHR. Vascular sympathetic innervation was visualized in the femoral artery by glyoxylic acid...

Excessive dietary salt intake can counteract the renoprotective effects of renin-angiotensin system (RAS) blockade in hypertensive patients with chronic kidney disease (CKD). In rodents, salt loading induces hypertension and renal damage by activating the mineralocorticoid receptor (MR) independently of plasma aldosterone levels. Thus, high salt-induced resistance to RAS blockade may be mediated by MR activation. To test this, a post hoc analysis of the Eplerenone Combination Versus Conventional Agents to Lower Blood Pressure on Urinary Antialbuminuric Treatment Effect (EVALUATE) trial was conducted...

We newly manufactured miso rich in angiotensin-converting enzyme (ACE) inhibitory activity (Marukome MK-34-1, shinki miso) and investigated its antihypertensive properties in rat models of genetic hypertension. ACE inhibitory activity was tenfold higher in shinki miso than in commercially available Marukome Nenrin miso (nenrin miso). The inhibitory activity of shinki miso was confined to <3 kDa fractions and was detected in several fractions with high polarity by C18 high-performance liquid chromatography...

The introduction in the past few years of advanced optical coherence tomography (OCT) techniques has greatly increased our understanding of the choroid, which is the most important vascular layer of the eye. Our study aimed to assess choroidal thickness by using swept-source OCT (SS-OCT) in essential hypertensive patients (EHs) with and without early-stage chronic kidney disease (CKD). We enrolled 100 EHs, of whom 65 were without kidney damage, and 35 had stage 1-3 CKD. In all of the participants, SS-OCT and a routine biochemical workup were performed...

Digit ratio (2D:4D) is a biomarker of prenatal hormone exposure levels; this biomarker is negatively related to prenatal androgen exposure and positively related to prenatal estrogen exposure. We investigated the correlation between digit ratio (2D:4D) and blood pressure. A school-based survey of 687 adolescents aged 8-15 years was conducted. The ring finger (4D) and index finger (2D), systolic blood pressure (SBP), diastolic blood pressure (DBP), testosterone, and estradiol levels were measured. Their dietary behaviors and physical and sedentary activity time were surveyed...

A high-fat diet (HFD) induces an increase in arterial pressure and a decrease in baroreflex function, which may be associated with increased expression of angiotensin type 1 receptor (AT1R) and pro-inflammatory cytokine genes and reduced expression of the angiotensin type 2 receptor (AT2R) gene within the nucleus of the solitary tract (NTS), a key area of the brainstem involved in cardiovascular control. Thus, in the present study, we evaluated the changes in arterial pressure and gene expression of components of the renin-angiotensin system (RAS) and neuroinflammatory markers in the NTS of rats fed a HFD and treated with either an AT1R blocker or with virus-mediated AT2R overexpression in the NTS...

Inflammation was cross-sectionally associated with subclinical wall remodeling and hypertension. Whether longitudinal changes (∆) in inflammation, myocyte injury (troponin T), and stretch (N-terminal-pro-B-type natriuretic peptide) are associated with hypertension and ECG left ventricular hypertrophy (ECG-LVH) is unclear. The first prospective analysis in Africa assessing these associations included a cohort of Black and White teachers (N = 338; aged 20-63 years). Fasting blood samples were obtained to measure tumor necrosis factor-alpha (TNF-α), cardiac troponin T (cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP)...

REVIEW
Yuanyuan Liu, Liquan Wang, Hongjun Shi
Pre-eclampsia (PE) is a pregnancy-specific syndrome that is characterized by hypertension and proteinuria. The etiology of PE is not completely understood but is believed to involve placental insufficiency and maternal vascular damage. Growing evidence supports an important role for the apelin receptor (APJ) system in regulating cardiovascular physiology. There are two vertebrate APJ ligands, APELIN and ELABELA, both of which mediate vasodilatory functions. A recent study linked deficient ELABELA signaling and the development of PE, though the molecular mechanism remains largely unknown...

Hypertensive disorders of pregnancy (HDP) represent a frequent disorder among pregnancies. Women with severe hypertension in pregnancy are at increased risk of maternal complications and require antihypertensive drug therapy. This study aimed to systematically review randomized control trials of antihypertensive drug(s) treating non-severe hypertension during pregnancy to estimate the effectiveness and safety of this intervention. On May 8, 2018, we searched PubMed, Cochrane Library, and Ichu-Shi with no restriction on publication year...

The purpose of this study was to identify the effects of various obesity phenotypes and metabolic abnormalities on cardio-cerebrovascular disease. We performed a large-scale, cross-sectional study including 10,089 participants aged ≥18 years in the National High-Technology district of Suzhou, China, from March 2016 to April 2016. Cardio-cerebrovascular disease included stroke and coronary heart disease. The prevalence rates of cardio-cerebrovascular disease among people with normal weight, overweight, and obesity in the unhealthy metabolism subgroup were higher than those among the three BMI groups in the healthy metabolism subgroup...

In this observational study, we aimed at investigating the influence of excess weight and traditional cardiovascular risk factors on vascular structure and function in a cohort of overweight/obese children. Sixty-six obese and 4 overweight children (age 11.5 ± 2.4 years; female n: 30) underwent office and ambulatory BP measurements (ABPM); ultrasound was used to measure carotid intima-media thickness (cIMT), endothelial function by Flow-Mediated Dilation (FMD) and carotid distensibility (cDC); and digital photopletismography was used to measure stiffness index (SIDVP )...

Increased blood pressure (BP) variability (BPV) is associated with high cardiovascular risk in hemodialysis. Studies on the effects of antihypertensive drugs on BPV in hemodialysis are scarce. This study examines the effects of nebivolol and irbesartan on short-term BPV in patients with intradialytic hypertension. This randomized-cross-over study included 38 patients (age: 60.4 ± 11.1 years, male: 65.8%) with intradialytic hypertension (intradialytic-SBP increase ≥ 10 mmHg at ≥4 over 6 consecutive sessions)...

Adrenal venous sampling (AVS) is the gold standard test for distinguishing between unilateral and bilateral primary aldosteronism (PA); however, AVS requires advanced and time consuming technique. The needs for AVS have been increasing due to the increased utilization of screening for PA. An efficient selection of unilateral PA, such as aldosterone-producing adenoma (APA), before AVS is useful to avoid undesirable AVS in bilateral PA, such as idiopathic hyperaldosteronism. In this study, 40 patients who received all three confirmatory tests, including the captopril challenge test, furosemide upright test and adrenocorticotropin (ACTH) stimulation test (AST), and who were diagnosed as having PA by AVS were recruited...
