Background: Brain ischemic disorders are common diseases of neural systems. One of the predisposing factors affect to the brain ischemia is systemic hypertension. The aim of this study was the determination of relation between blood pressure and spread of brain ischemia in CT scan in brain ischemia patients. Materials & Methods: In the first stage and on the basis of research group, we selecte...

Background: Arterial pressure is one of the most important physiological variables and often needs to be monitored repeatedly or continuously in perioperative period. Arterial pressure monitoring is one of the standard monitoring in operating room. During general anesthesia, blood pressure can be measured by using a noninvasive arterial pressure method or continuous invasive arterial pressure b...

To separate the effects of coronary flow, perfusion pressure, and oxygen delivery on left ventricular diastolic compliance and diastolic wall thickness, isolated buffer and blood-perfused rabbit hearts with left ventricular volume controlled by a fluid-filled intraventricular balloon were subjected to the following interventions: complete global ischemia, hypoxia at constant coronary flow, hypo...

The Literature review indicates that the high blood pressure has a different prevalence in various population of Iran and in the age group of 35 and above the rate varies from 7% in Qushguai tribe to 30% in Teheran and Anzali. The purpose of this study is to know whether the essential hypertension begins at the early age of life; and also to standardizing the normal value of blood pressure in c...

Our goal is to test the effect of both rare and common variants in a blood pressure study. We use a pathway-based approach, gene-set enrichment analysis, to search for related genes affecting 4 phenotypes: systolic blood pressure, diastolic blood pressure, the difference between each of them and mean arterial pressure, which is a weighted linear combination of systolic and diastolic blood press...

Surveys of arterial pressure carried out in rural and urban communities in Western Nigeria showed a steady rise in systolic values with age, this trend being less marked with diastolic pressures. Blood pressure levels were similar in women from rural and urban areas, but seemed much higher in urban than in rural men. The incidence of proteinuria was lowest in the female urban group. In general,...

Very few discoveries have had such a large impact on and relevance to clinical medicine as the noninvasive measurement of the diastolic blood pressure. A number of gifted physiologists and clinicians were ineffectively in search of a noninvasive method to determine the diastolic pressure. Nonetheless, the quantification of the diastolic BP was not achieved by any of these clinical or physiologi...
