Hypertension is both a cause and a consequence of chronic kidney disease, but the prevalence of chronic kidney disease throughout the diagnostic spectrum of blood pressure has not been established. We determined the prevalence of chronic kidney disease within blood pressure categories in 17 794 adults surveyed by the National Health and Nutrition Examination Survey during 1999–2006. Diagnosed h...

In 106 slightly anaesthetised adult mongolian gerbils one common carotid artery (CCA) was ligated and the blood pressure in the distal and in the proximal stump was monitored for 8 minutes. The mean distal CCA stump pressure of the 39 nonsurvivors was 15 (+/- 6) mm Hg, that of the 25 survivors with retinocerebral infarcts was 25 (+/- 6) mm Hg, and that of the 42 intact survivors was 31 (+/- 7) ...
The present study was designed to investigate the effect of acute sympathetic denervation on the regional cerebral blood flow (CBF) autoregulation during acute elevation of blood pressure in spontaneously hypertensive rats (SHR) and normotensive Wistar Kyoto rats (WKY). CBF to the parietal cortex and thalamus was measured by the hydrogen clearance method and, to test autoregulation, systemic ar...
We investigated the relation between renal perfusion pressure and the release of a renal vasodepressor substance in vivo to determine whether this substance was released at physiological pressures. We perfused the left kidneys of anesthetized rabbits using an extracorporeal circuit that allowed renal perfusion pressures to be set at 65 mm Hg (control) and increased to 95, 125, 155, or 185 mm Hg...
Introduction: Hypertension is the most important modifiable cardiovascular risk factor. Hypertension is the leading global risk factor for mortality and as the third leading risk factor for cardiovascular disease burden. This survey has been conducted to determine the prevalence of hypertension among the inhabitants of 25-64 aged in 17th zone of Tehran, selected as Population Lab Region. Meth...
Hypertension remains poorly controlled in the United States. Improvement of its management will require an understanding of the patient characteristics and treatment factors associated with uncontrolled hypertension. We studied antihypertensive medication use, comorbidity, and blood pressure measurements for 525 hypertensive patients in 3 different healthcare systems over a 1-year period. We co...
BACKGROUND Hypertension contributes to cardiovascular morbidity and mortality. We assessed the safety and efficacy of a central iliac arteriovenous anastomosis to alter the mechanical arterial properties and reduce blood pressure in patients with uncontrolled hypertension. METHODS We enrolled patients in this open-label, multicentre, prospective, randomised, controlled trial between October, ...
The objective of this study was to determine if males with a deficient androgen receptor would develop hypertension when crossed with a hypertensive parent. Female King-Holtzman rats (n = 15), heterozygous for the testicular feminization (Tfm) gene, were crossed with male spontaneously hypertensive rats (SHR), and blood pressure was measured weekly from 5-14 weeks in the F1 hybrid males. Approx...
Background—Hypertension is common and treatable, but detection and control remain a major health challenge. This study sought to determine population trends in blood pressure and in the control of hypertension in the Minneapolis/St. Paul area (2010 population, 2.85 million) from 1980 to 2009. Methods and Results—Surveys of risk factors were performed every 5 years among randomly selected adults...
