Background: To describe factors contributed to the maternal deaths occurred in the West Azerbaijan, Iran from 2002 through 2011. Materials and Methods: In a cross-sectional study, data on the maternal deaths obtained from the national maternal mortality surveillance system were analyzed. The three delays model was used so as to recognize contributing factors of maternal deaths due to obstetric ...

We examined the hypothesis that the renin-angiotensin system plays an important role in vascular remodeling (defined as reduced external diameter) during chronic hypertension. We measured pressure, diameter, and cross-sectional area of the vessel wall in maximally dilated cerebral arterioles in transgenic mice that overexpress both human renin and human angiotensinogen and in spontaneously hype...

Background—Little is known about trends in the mortality rate among people with hypertension in the United States. The objective of the present study was to examine the change in the all-cause mortality rate among people with and without hypertension in the United States and whether any such changes differed by sex or race. Methods and Results—Data from 10 852 participants aged 25 to 74 years o...

Although systemic hypertension is a common clinical condition, hypertensive emergencies are unusual in clinical practice. There are some situations, however, that qualify as hypertensive emergencies or urgencies. It is important, therefore, to diagnose these acute conditions, in which immediate treatment of hypertension is indicated. The diagnosis of hypertensive emergencies depends on consider...

BACKGROUND Hypertensive crisis in children is a relatively rare condition presenting with elevated blood pressure (BP) and related symptoms, and it is potentially life-threatening. The aim of this study was to survey children with first attacks of hypertensive crisis arriving at the emergency department (ED), and to determine the related parameters that predicted the severity of hypertensive cr...

Fifty patients with spontaneous lobar haematomas were reviewed. Thirty-two were normotensive and eighteen were hypertensive. Vomiting, seizures, and altered consciousness were more common in hypertensive than in normotensive patients. Haematoma size (greater than 4.0 cm) and intraventricular extension occurred most commonly in hypertensive and rarely in normotensive patients. Twenty-eight per c...

1. The tonin concentration of saliva and submaxillary glands was studied in one-clip hypertensive rats with or without the contralateral kidney. 2. Salivary tonin concentration was elevated in one-kidney hypertensive rats, but not in one-kidney normotensive or two-kidney, one-clip hypertensive rats. In contrast, an elevated submaxillary gland tonin concentration was found only in uninephrectomi...
