Adrenal tumors are increasingly found incidentally during imaging examinations. It is important to distinguish pheochromocytomas from other adrenal tumors because of the risk of hypertensive crisis. Although catecholamines and their metabolites are generally used to diagnose pheochromocytoma, false-positive test results are common. An effective screening method to distinguish pheochromocytoma from adrenal incidentalomas is needed. We analyzed 297 consecutive patients with adrenal incidentalomas. Our findings included 162 non-functioning tumors, 47 aldosterone-producing adenomas, 26 metastases, 22 cases of subclinical Cushing's syndrome, 21 pheochromocytomas, 12 cases of Cushing's syndrome, and 7 adrenocortical cancers...

Our previous report indicated that vascular injury enhances vascular remodeling in fetal growth restriction (FGR) mice. The angiotensin II type 2 receptor (AT2R) is relatively highly expressed in fetal mice. Therefore, we investigated the roles of AT2R in FGR-induced cardiovascular disease using AT2R knockout (AT2KO) mice. Dams (wild-type and AT2KO mice) were fed an isocaloric diet containing 20% protein (NP) or 8% protein (LP) until delivery. Arterial blood pressure, body weight, and histological changes in organs were investigated in offspring...

Marinobufagenin (MBG) is an endogenous steroidal α1-Na+K+-ATPase inhibitor. Because of its role in sodium handling, MBG has been associated with both antihypertensive and prohypertensive effects in normal physiology and pathology. MBG is positively associated with blood pressure in Dahl salt-sensitive rats exhibiting a similar hypertensive phenotype to black populations, characterized by impaired urinary Na+ excretion. However, clinical studies exploring blood pressure (BP)-related effects of MBG in black populations are scant...

Cardiovascular autonomic nervous system function can be assessed using an orthostatic challenge to induce arterial wave reflection. While arterial reflection is typically estimated using a central augmentation index, a superior estimation can be obtained using pulse wave separation analysis to estimate the aortic backward pressure wave (Pb). However, to be of value in a clinical or research setting, an assessment tool must be precise (reliable). Therefore, this study sought to determine the measurement precision of Pb responses to a modified tilt-table test...

Wrist circumference is a clinical marker for insulin-resistance in overweight/obese children and adolescents. Insulin resistance is considered a major determinant of increased vascular resistance and hypertension. The aim of the study was to investigate the association between wrist circumference and systolic (S) and diastolic (D) blood pressure (BP) in a population of overweight/obese children and adolescents. A population of 1133 overweight/obese children and adolescents (n = 1133) were consecutively enrolled...

Preeclampsia has known associations with insufficient placental perfusion. The large-conductance Ca(2+)-activated K(+) (BKca) channels that have recently been found to play important roles in cellular growth and vasodilatation could potentially participate in the development of preeclampsia. However, the mechanisms by which downregulated BKca channels are involved in the development of preeclampsia remain unknown. In this study, we investigated the mechanism(s) underlying the impairment of vascular tone regulation by BKca channels in human placental chorionic plate arteries (CPAs) in preeclampsia...

Elective coronography has low diagnostic yield for obstructive coronary artery disease (CAD). We aim to determine whether non-invasive aortic stiffness assessment improves diagnostic accuracy of CAD screening by reducing the number of false-positive results from the cardiac stress test. A cross-sectional study was conducted from January 2013 to September 2014 in our medical center. Electrocardiogram (ECG) stress test coupled with nuclear imaging was performed in 367 consecutive patients routinely followed for myocardial ischemia screening...

Atrial fibrillation may affect blood pressure measurements. The ankle-brachial index (ABI) is a ratio of systolic blood pressure measured on the lower and upper limbs that may also be affected by arrhythmia. The purpose of the study was to investigate whether atrial fibrillation influenced ABI results. Ninety-nine patients (age 66.6±11 years, 63 males and 36 females) who underwent electrical cardioversion of atrial fibrillation were investigated. ABI measurements using the Doppler method were performed on both lower extremities before and after electrical cardioversion...

We tested whether hypertension favors the development of additional cardiometabolic changes in fructose-fed ovariectomized rats and how it affects aerobic exercise training (ET) effects. All rats received fructose in drinking water (10%) beginning at weaning, were ovariectomized at 10 weeks of age and divided into the normotensive sedentary (NFOS) and trained (NFOT) and hypertensive sedentary (HFOS) and trained (HFOT) groups. ET was performed on a treadmill. Arterial pressure (AP) was directly recorded; heart rate and AP variabilities were analyzed...

Reversible posterior leukoencephalopathy syndrome (RPLS) is a critical maternal complication in some pre-eclampsia (PE) and nearly all eclampsia patients; RPLS is associated with high blood pressure (BP). However, the effect of BP on RPLS and the different characteristics of RPLS in PE or eclampsia are largely unknown. We consecutively collected data from 69 patients who were diagnosed with RPLS in PE or eclampsia between 2013 and 2017. The BP and biochemical indicators at onset and post onset of RPLS were examined to explore their likely correlation with RPLS...

Hypertensive disorders of pregnancy (HDP) is a common disease and is believed to be a multifactorial genetic disease. Stromal interaction molecule 1 (STIM1) was previously reported to regulate the concentration of Ca(2+) and vascular contraction. The aim of the present study was to assess the association between HDP and single-nucleotide polymorphisms (SNPs) or haplotypes in the human STIM1 gene via case-control studies. On the basis of a database on the National Center of Biotechnology Information website, we selected five SNPs in the human STIM1 gene and performed an association study with 139 HDP patients and 162 age-matched non-HDP subjects...

Promoter methylation is a key mechanism in the epigenetic reprogramming of gene expression patterns. Here, we investigated the contribution of DNA methylation and the associated expression and function of large-conductance Ca(2+)-activated K(+) (BKCa) channel in mesenteric arteries when hypertension was superimposed on aging. Male Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHR) at young (12 weeks), adult (36 weeks) and old (64 weeks) life stages were used. BKCa channel currents, BKCa channel activity in regulating vascular tone, and BKCa channel β1 subunit (BKβ1) function and expression were greater in mesenteric arteries from SHR than from age-matched WKY controls...

The pathogenesis of preeclampsia (PE) involves a number of biological processes that may be directly or indirectly affected by glucocorticoid (GC) and vitamin D. GC exposure increases the risk of PE, and 1,25-dihydroxyvitamin D3 (1,25-(OH)2D3) deficiency may result in PE. The purpose of the present study was to confirm the involvement of GC/1,25-(OH)2D3 axis in the pathogenesis of PE. In the study, cortisol levels of PE patients were found to be higher than that of non-complicated pregnancies, while 1,25-(OH)2D3 were decreased in both PE women and GC-induced PE rats...

Hypertensive disorders of pregnancy are known to be a risk factor for future cardiovascular diseases. In contrast, there is a paucity of data on the not so distant future prognosis of hypertensive disorders of pregnancy. In the present study, we evaluated the incidence of the diseases causing cardiovascular problems (hypertension, diabetes mellitus, dyslipidemia and metabolic syndrome) 5 years after delivery in Japanese women with hypertensive disorders of pregnancy. We performed a double-cohort study and compared medical conditions between women with and without a history of hypertensive disorders of pregnancy...

The frequent accompaniment of hypertension by orthostatic circulatory disorders prompted us to investigate the effect of repeated and sustained head-up and head-down tilt positions on cardiovascular responses in spontaneously hypertensive rats vs. Wistar rats using radiotelemetric implants. Repeated orthostasis caused a transient elevation in blood pressure (7.3±1.7 mmHg) and heart rate (39.7±10.5 BPM), while repeated antiorthostasis led only to reversible tachycardia (85.6±11.7-54.3±16.8 BPM) in spontaneously hypertensive rats...

Blunted nocturnal dipping in blood pressure (BP) is associated with increased cardiovascular disease (CVD) risk in middle-aged/older adults. The prevalence of blunted nocturnal BP dipping is higher in persons with obesity and diabetes, conditions that are also associated with elevated aortic stiffness and inflammation. Therefore, we hypothesized that elevated glycemia, inflammation and aortic stiffness would be inversely associated with the magnitude of nocturnal systolic BP dipping among middle-aged/older adults with obesity at high CVD risk...

High blood pressure (HBP) is a major concern in pediatric populations. Adiposity is highly related to HBP in youths; however, whether body mass index (BMI) or waist circumference (WC) is more strongly associated with HBP in this population is unclear. This cross-sectional study, involving schoolchildren between 10 and 17 years of age from public and private schools, assessed direct measurements of BMI, WC and blood pressure. The socioeconomic level, sedentary behavior, physical activity, alcohol consumption and smoking history were obtained through a questionnaire...

Epidemiological and clinical studies have investigated the influence of hypertension on chronic kidney disease (CKD), but limited data are available for the associations of white-coat hypertension (WCHT), masked hypertension (MHT) and sustained hypertension (SHT) with kidney dysfunction in general populations. We examined the associations of these types of hypertension with CKD (albuminuria and reduction in estimated glomerular filtration rate (eGFR)) in a cross-sectional survey of 2974 community-dwelling Japanese aged ⩾40 years...
