Shift work with sleep disruption is a systemic stressor that may possibly be associated with blood pressure dysregulation and hypertension. We hypothesize that rotation to a simulated night shift with sleep deprivation will produce blood pressure elevations in persons at risk for development of hypertension. We examined the effects of ...

Most deaths in autosomal dominant polycystic kidney disease (ADPKD) are attributable to cardiovascular disease (CVD). We examined novel CVD biomarkers in different stages of ADPKD. We recruited 50 hypertensive subjects with ADPKD with estimated GFR (eGFR) of >60 ml/min per 1.73 m(2); 52 hypertensive subjects with ADPKD with eGFR of ...

Structural changes in the large resistance vessels in hypertension amplify resistance responses in vitro, but their role in vivo has been controversial. To resolve this matter, we re-examined earlier data in Page hypertension. Total peripheral resistance (TPR) and total peripheral conductance (TPC) responsiveness were compared in hypertensive and normotensive rabbits, ...

Clinical practice and research provide evidence indicating the involvement of psychological factors in essential hypertension. Little is known about interoception (i.e. the ability of perceiving bodily signals) in essential hypertension. The present study focused on the assessment of interoceptive awareness in newly diagnosed-untreated hypertensives by means of ambulatory blood pressure ...

Endothelin-1 (ET-1) is a potent vasoconstrictor derived from the endothelium. However, most large scale cross-sectional studies in humans have indicated no relationship between plasma ET-1 levels and hypertension. The present study was designed to determine whether high plasma ET-1 levels predict the development of hypertension. A total of 1,492 subjects ...

BACKGROUND: Thrombotic, rather than hemorrhagic, events represent a major complication of hypertension. This study aims to explore the mechanism of the hypercoagulative state in hypertension and to assess its clinical significance. HYPOTHESIS: The hypercoagulative state and even the prothrombotic state exists in patients with hypertension. This may be attributed to ...

Chronic hypoxia results in pulmonary hypertension. To investigate the role of Na+/H+ exchange in this process, we determined the effect of amiloride, a Na+/H+ exchange inhibitor, on hypoxic pulmonary hypertension and pulmonary arterial smooth muscle cell proliferation, both in vivo and in vitro. Sprague-Dawley rats were placed either in a ...

Hypertension is the most important modifiable risk factor for primary intracerebral hemorrhage (ICH), but little is known of the effect of preceding hypertension on outcome. Because high mean arterial blood pressure (MABP) at admission is an independent predictor of early death in patients with ICH, we explored its role on ...

Exercise is recommended as a lifestyle intervention in preventing hypertension based on epidemiological findings. However, previous intervention studies have presented mixed results. This discrepancy could be associated with shortcomings related to sample sizes or the inclusion of normotensive participants. The aim of this prospective cohort study (N = 463) was ...

Fatty acid (FA) synthesis enzymes (FA synthase (FASN) and acetyl-CoA carboxylase (ACC)) are related to metabolic alterations such as obesity, insulin resistance, or dyslipidemia. Due to the fact that there is no literature that relates FASN and ACC expression with hypertension, we investigate how FASN and ACC expression in adipose ...

BACKGROUND: We have used a novel ultra high-frequency (55MHz) ultrasound technique to non-invasively measure the radial arterial vessel wall and separate the intima-media (IMT) complex into measurements of intima and media thickness (IT and MT). Since no previous study has measured IT and MT separately in individuals with prehypertension and ...

Healthy skin is protected from pressure-induced ischemic damage because of the presence of pressure-induced vasodilation (PIV). PIV relies on small sensory nerve fibers and endothelial function. Since aging alters both nervous and vascular functions, we hypothesized that PIV is altered with aging. We compared PIV in non-neuropathic and neuropathic older ...

BACKGROUND: Hypertension is a disease characterized by end-organ complications, leading to high morbidity and mortality in many cases. People with untreated or uncontrolled hypertension often run the risk of developing complications directly associated with the disease. Left ventricular hypertrophy (LVH) has been shown to be a significant risk factor for ...

The anti-hypertensive effect of GABA-rich Chlorella was studied after oral administration for 12 weeks in the subjects with high-normal blood pressure and borderline hypertension in the placebo-controlled, double-blind manner in order to investigate if GABA-rich Chlorella, a dietary supplement, is useful in control of blood pressure. Eighty subjects with Systolic ...

Insulin-like growth factor-I (IGF-I) reduces arterial blood pressure. Since administration of capsaicin and isoflavone increases serum levels of IGF-I by sensory neuron stimulation in subjects with alopecia, it is possible that administration of capsaicin and isoflavone reduces arterial blood pressure in patients with hypertension. Systolic and diastolic blood pressure (BP) ...

Obesity and hypoadiponectinemia are often associated with high blood pressure. Moreover, microvascular dysfunction is reported to be an early event in patients with hypertension and may be involved in the pathogenesis of organ damage. We investigated the impact of 8-week moderate-intensity aerobic training on adiponectin plasma levels and skin microvascular ...

The predisposition to thrombogenesis is increased in essential hypertension, and hypertensive patients are prone to develop more vulnerable atherosclerotic plaques. To evaluate the possible influence of family history of hypertension on some indicators of early atherosclerosis, we studied eighty-five healthy normotensive individuals with (FH+) or without (FH-) family history of ...

Recent studies have demonstrated the presence of autoantibodies against alpha(1)-adrenoceptor (alpha(1)-AAB) in the serum of patients with primary hypertension, and that these autoantibodies exert adrenergic-agonist-like effects. However, their role in the development of hypertension remains unclear. The current study determined whether alpha(1)-AAB can cause vascular contraction, and further investigated the ...

Cognitive dysfunction is fairly common after noncardiac surgery and may be related to intraoperative blood pressure management. The authors present an analysis of risk factors for cognitive deterioration after spine surgery in older patients, with particular emphasis on intraoperative blood pressure in normotensive and hypertensive patients. This is a post ...

BACKGROUND: Hypertension is one of the principal risk factors for cardiovascular disease. We aimed to evaluate the impact of hypertension on fibrinolytic balance and endothelial function by measuring plasma levels of plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen activator antigen (tPA), tPA/PAI-1 complex and fibrinogen. METHODS: Patients enrolled into the study ...

OBJECTIVES: It is known that the risk of cerebral stroke recurrence in post-stroke patients is comparatively higher than in normal subjects, and it is suggested that autonomic nervous system dysfunctions elevate this risk. We investigated the anti-hypertensive effects of cilnidipine, a Ca antagonist which suppresses sympathetic nerve activation, in hypertensives ...

Individuals genetically susceptible to hypertension may have preexisting membrane defects influencing cell sodium permeability. Fourteen Minnesotan families of Northern European descent were selected as having one or both progenitors with either high (HP) or low (LP) erythrocyte sodium permeability. We earlier found that over one-half of the (22)Na(+) influx into ...

Increased levels of G protein coupled receptor kinase GRK2 appear to participate in hypertension presumably through the desensitization of beta adrenergic receptors (betaARs) that mediate vasodilatation. There are contrasting data on the occurrence of betaAR desensitization in the vasculature, we therefore investigated betaAR vasodilatation and desensitization in normotensives and in ...
