Classic hypertensive retinopathy has been well known since the first categorization of retinal vascular changes with the ophthalmoscope made by Keith-Wagener and Barker. Clinicians were interested in using a noninvasive tool to show that severity of vascular hypertension was predictive of mortality. Recently, a microvascular etiology has been suggested to ...

Cardiovascular disease is emerging as a leading cause of morbidity and mortality in Latin America. Population-based data regarding the prevalence of hypertension and hypertension subtypes in Andean Hispanic populations are scarce. The authors performed a population-based study that included 1878 Peruvian Andean adults to determine: (1) the prevalence, awareness, and ...

The effect of a course of electroconvulsive therapy (ECT) on blood pressure control in hypertensive patients has not been studied. We retrospectively examined pre- and post-ECT blood pressures in hypertensive and nonhypertensive patients. In neither group was there a statistically significant change in blood pressure with a course of ECT. ...

The cerebral hemispheres show prominent involvement in hypertensive encephalopathy far more frequently than the brainstem. Two patients with severe paroxysmally accelerated hypertension associated with brainstem hyperintensity in T2-weighted magnetic resonance images are presented. Both present hyperintense lesions improved dramatically in appearance after stabilization of blood pressure. Extreme acceleration of hypertension ...

Hypertension affects approximately 25% of adults and is a major risk factor for cardiovascular disease. Although there are currently adequate therapeutic options for humans with hypertension, the molecular mechanisms underlying hypertension are still relatively unknown. The generation of hypertensive animal models provides an excellent modality to not only study the ...

The different vascular phenotypes found in hypertension comprise different aspects. They may be clinical, diagnostic, structural, mechanical, functional, cellular and extracellular, signaling and molecular, proteomic, and gene expression phenotypes. In this manuscript the emphasis will be on the various structure, mechanics, dysfunction, and cell and signaling changes that can be ...

Pathogenic mechanisms for essential hypertension are unclear despite striking efforts from numerous research teams over several decades. Increased production of reactive oxygen species (ROS) has been associated with the development of hypertension and the role of ROS in hypertension has been well documented in recent years. In this context, it ...

Hypertension is an important public health problem affecting more than 50 million individuals in the US alone. The most common form, essential hypertension, results from the complex interplay between genetic predisposition and environmental influences. In contrast, monogenic (mendelian) forms of hypertension are caused by single gene mutations that are influenced ...

BACKGROUND: Despite improved treatment of hypertension and decreasing rates of stroke and coronary heart disease, the reported incidence of hypertensive end-stage renal disease (ESRD) increased during the 1990s. However, bias, particularly from variations in acceptance into ESRD treatment (ascertainment) and diagnosis (classification), has been a major source of error when ...

Magnesium affects blood pressure by modulating vascular tone and reactivity. It acts as a calcium channel antagonist, it stimulates production of vasodilator prostacyclins and nitric oxide and it alters vascular responses to vasoactive agonists. Magnesium deficiency has been implicated in the pathogenesis of hypertension with epidemiological and experimental studies demonstrating ...

The World Health Report 2002 identified hypertension, or high blood pressure, as the third ranked factor for disability-adjusted life years. Hypertension is one of the primary risk factors for heart disease and stroke, the leading causes of death worldwide. Recent analyses have shown that as of the year 2000, there ...

While almost two-thirds of all strokes and one-half of all myocardial infarctions could be prevented if hypertensive individuals had their blood pressures optimally controlled, only a minority of hypertensive individuals (even in publicly funded health care systems with subsidization of medication costs) achieve target blood pressures. Traditional hypertension guidelines have ...

We describe a 55 year-old woman with longstanding hypertension who developed hypokalaemia following diuretic treatment. Investigations revealed primary hyperaldosteronism due to an adrenal adenoma, and normal blood pressure was restored after surgical removal of the tumour. Primary hyperaldosteronism is a potentially curable cause of hypertension and should be considered in ...

There are conflicting data in the literature regarding the expression pattern of the vascular matrix metalloproteinase (MMP) system and their inhibitors (TIMPs) in human hypertension. The authors hypothesized that MMP-2, MMP-9, and TIMP-1 would be abnormal in hypertension, reflecting alterations in extracellular matrix (ECM) turnover. The authors measured plasma levels ...

Posterior reversible encephalopathy syndrome (PRES), also known as reversible posterior leukoencephalopathy syndrome (RPLS), is most often associated with hypertensive emergencies and is characterized by seizures, mental status changes and visual disturbances. We report a case of a previously healthy young man who developed multiorgan failure and transient cortical blindness following ...

There is no widely accepted definition of intradialytic hypertension. Arbitrary clinical definitions have included an increase in blood pressure during or immediately after hemodialysis, a rise in blood pressure during the second or third hour of dialysis, and an increase in blood pressure that is resistant to ultrafiltration. To date, ...

We apply a new methodology to investigate goal setting by hypertensive patients that uncovers the reasons why people have a goal to manage hypertension or not (e.g. to reduce/maintain one's current blood pressure). The reasons are found to consist of superordinate goals in support of one's focal hypertension goal and ...

Malignant hypertension may be the first manifestation of systemic hypertension. We report a clinical case of a Caucasian 41-year-old man with no previous history of blood hypertension seen at casualty because of blurred vision. Fundus examination disclosed optic disk swelling, retinal hemorrhages and infarcts. The blood pressure was 220/130 mmHg. ...

Hypertension is the leading cause of cardiovascular disease worldwide. Prior to 1990, population data suggest that hypertension prevalence was decreasing; however, recent data suggest that it is again on the rise. In 1999-2002, 28.6% of the U.S. population had hypertension. Hypertension prevalence has also been increasing in other countries, and ...

Compared to chronic hypertension, little is known about the pathophysiology of acute hypertension and its recovery. To characterize this, we investigated the functional and structural properties of the common carotid arteries (CCA) from 35 rats. We established a unilateral and reversible carotid arterial hypertension model using the partial transverse aortic ...

Epoxide hydrolases are a group of enzymes that convert the epoxide group of chemical compounds to corresponding diols by the addition of water. Soluble epoxide hydrolase (sEH, formerly referred to as cytosolic epoxide hydrolase), which is widely distributed in mammalian tissues, is the primary enzyme responsible for the conversion of ...

Hypertension is associated with cardiovascular risk and systemic target organ damage. Retinopathy is considered one of the indicators of target organ damage. This review focuses on recent studies on hypertensive retinopathy and their implications for clinical care. Early recognition of hypertensive retinopathy signs remains an important step in the risk ...

During acute hypertension, Na(+)/H(+) exchangers (NHE3) retract from top to base of proximal tubule microvilli (MV) and Na(+) reabsorption decreases in proximal tubule. This study aimed to determine whether the actin-based motor myosin VI coordinately retracts with NHE3 in response to acute hypertension. BP was raised approximately 50 mmHg in ...

Increased catecholamine secretion from neuroblastomas can occasionally be demonstrated, but severe hypertension is uncommon. We report the perioperative management of a 5 year old child with stage III adrenal neuroblastoma who presented with malignant hypertension and high norepinephrine and dopamine levels. Hypertensive crises occurred during anesthesia for surgical biopsy and ...
