In a London suburban general practice 87 hypertensives have been followed up for more than 15 years. These represented one third of all those (270) aged 30-59 diagnosed as being hypertensive. Females outnumbered males by 2.5: 1. Most (85 per cent), had mild or moderate high blood pressure at first ...

Diazoxide is a potent and safe antipressor agent for parenteral administration in hypertensive emergencies. Its rapidity of effect provides distinct advantages. Drug resistance does not develop in responsive patients and adverse effects are mild and infrequent. The minor changes in blood urea concentration, despite a marked reduction in blood pressure, ...

1. There were significant correlation between hyperlipidemia and obesity, hypertension, abnormal ECG and abnormal eyeground. 2. The incidence of cerebral hemorrhage was closely associated with hypertension but not with hyperlipidemia. 3. It was proved that hypertension with both hyper-Ch and hyper-TG was highly related to the development of cerebral infarction. ...

A 26-year-old woman who had been taking an oral contraceptive preparation for two years developed malignant hypertension. Investigation failed to elicit any renal or other cause for her hypertension, but control of blood pressure was obtained by withdrawal of the oral contraceptive agent and antihypertensive therapy. Subsequently, after withdrawal of ...

In a statewide survey of hypertension prevalence among pesticideformulating workers and controls in Oregon, we found no difference in mean systolic and diastolic blood pressure values but a modest excess of hypertension prevalence among chlorophenoxy herbicide workers which was largely explained by a greater constitutional predisposition to hypertension as estimated ...

Sixty patients out of 1,844 recovery room admissions had significant postoperative arterial hypertension. Nearly 60% of them had a history of hypertension. The postoperative hypertension usually began within 30 min from the end of operation and lasted about 2 hours. In 20% of the patients it lasted 3 hours or ...

A computer-based medical record system has been developed to help with research into hypertension and the management of patients with hypertension. Standard medical records are replaced by data collection forms and case notes printed by the computer. A computer-generated document for recording information at follow-up visits contains an up-to-date summary ...

Acute hypertension was produced in rats by the infusion of angiotensin amide for 2 to 4 hours. These animals were injected intravenously prior to sacrifice with either colloidal carbon or iron dextran particles. The mesenteric vessels from hypertensive and control animals were processed for electron microscopy. Ultrastructural alterations are found ...

The ultrastructure of retinal arterial vessels from rats with severe renal hypertension has been studied. The permeability of retinal vessels has also been examined by means of vascular labeling technics utilizing horseradish peroxidase and microperoxidase as tracer substances. Small retinal arteries and arterioles exhibit foci of smooth muscle necrosis characterized ...

Of 127 hypertensive patients aged 12 to 40 investigated by intravenous pyelography, abdominal aortography, and renal biopsy an underlying cause was found in 57%. The proportion with secondary hypertension was higher in young patients and in those with severe hypertension. Primary arteritis of the aorta was an important cause of ...

Abstract The purpose of this note is to consider some of the main factors affecting natural increase in England and Wales. Though the weight of the various factors is slightly different in Scotland, the population of England and Wales is so much larger that discussion of that country will serve ...

A trial of oral propranolol as a hypotensive agent was designed to provide adequate treatment periods. Twenty-eight patients with essential hypertension, with a mean blood pressure of 190/111 mm. Hg, were controlled on 120-320 mg. of propranolol daily. Their mean treated blood pressure was 153/91. They then entered, on a ...

The incidence of secondary hypertension in clinical practice is probably below 5%. The majority of those cases are of renal origin. Extensive and costly investigations for rarer forms of hypertension therefore do not appear justified. A comprehensive medical history, plus a good physical exam and some critical laboratory analyses can ...

Apart from seeking target organ damage, the investigation of hypertension is primarily aimed at finding a treatable cause of the hypertension. The finding of one such cause is usually construed as being the sole culprit responsible for the patient's elevated blood pressure. The existence of multiple aetiologies of secondary hypertension ...

The plasma protein pattern of patients with uncomplicated essential hypertension showed only slight variations from the normal while that of patients with severely malignant hypertension showed marked shifts. The fibrinogen and β-globulins were usually elevated beyond the normal range and the albumin decreased. In less severely malignant hypertension, the changes ...

A new study demonstrates that angiotensin-induced hypertension results in a marked decrease in expression of the β subunit of the BK channel, suggesting a role for this critical subunit in the regulation of vascular tone.

Hypertension is a prevalent condition in the middle years. About 25% of visits to family physicians are by patients with hypertension. Both case-detection and control of hypertension are important parts of practice. Unfortunately, the criteria used to diagnose and treat hypertension are variable, partly because of the lack of agreement ...

OBJECTIVE: To evaluate the effectiveness of a program to improve hypertension control practices in primary care. DESIGN: Retrospective quasi-experimental study. SETTING: Three hospital-based family medicine centres (FMCs) PARTICIPANTS: Two study groups of 100 randomly-selected adult patients each, who visited the study FMC before implementation of the hypertension program (from April ...

The concern over pressure regulation especially in cases of posture change and for hypertensive patients points to a need to better understand pressure regulation and to determine the causes of hypertension.

Phaeochromocytomas are rare catecholamine-secreting tumours which can mimic a variety of common clinical conditions, such as hypertension and angina. It is a potentially curable condition if discovered early, and clinicians should be alerted as to its presence in a young individual with hypertension or atypical angina-associated hypertension. Pharmacological mismanagement can ...

The possible relationship between the renal mechanism of volume control and blood pressure regulation is discussed. Expansion of the extracellular fluid (ECF) and plasma volumes was demonstrated following renal artery constriction in the rat; after about one month ECF volume returned to normal although hypertension persisted. Measurements of cardiac output ...

High blood pressure occurs in the majority of cases of chronic kidney disease, while renal damage is common in the more advanced cases of essential hypertension. In a population study of hypertensive disease, therefore, it is important to provide information on renal function. Determination of plasma creatinine concentration fails as ...

Alkavervir (Veriloid(R)), a new derivative of veratrum viride was used in the treatment of hypertension in ten children with acute nephritis. The patients had a variety of complications associated with hypertension-heart failure, convulsions, vomiting and headache. In all of them the blood pressure decreased soon after the drug was given.
