Following a screening survey for hypertension in Renfrew, a blood pressure clinic was established in a health centre. Three hospital doctors, each working an average of two sessions weekly, saw 368 patients. A specially trained nurse played an important part in the running of the clinic. Attendance of patients was ...

The Victorian community of the Borough of Queenscliffe (Queenscliff and Point Lonsdale) was screened for high blood pressure in May, 1975, and a high response rate was achieved. The prevalence of hypertension was lower than that reported from Albury in 1971, Brunswick in 1972 or Busselton in 1969, but the ...

The prevalence of primary and secondary hypertension was determined in a random sample of 7455 Swedish men aged 47 to 54 years. Three hundred and sizty-one men were undergoing treatment for hypertension. Seven hundred and ninety-eight men who had blood pressures above 175/115 mm Hg at preliminary screening were recalled ...

The prevalence of hypertension, defined as a diastolic blood pressure over 100 mmHg, among young Black women who attended a family planning clinic in Johannesburg, was 2,85%, while in those over 35 years of age it was 8,5%. There was no correlation between hypertension and urbanisation, occupation or urinary sodium ...

A controlled trial was undertaken to evaluate the practical consequences of screening in general practice. Of 2420 people aged 40-64 years examined in 1967-68, 191 (7.9%) had previously been told, at some time, that they had raised blood-pressure, other than during pregnancy. However, only 77 (3-2%) had any record of ...

Bilateral compression of the adrenal glands combined in mononephrectomy and followed by the imposition of a high NaC1 intake resulted in severe hypertension in all rats so treated. It was accompanied by enlargement of the heart, kidneys, and adrenal glands, atrophy of the thymus, and the occurrence of severe nephrosclerosis. ...

During 1973 through 1975, more than 1 million persons were screened in the nationwide Community Hypertension Evaluation Clinic (CHEC) program at 1,171 sites. While those screened were not from defined populations, findings paralleled those of recent surveys of US population samples. First, CHEC confirmed the scope of the problem of ...

Partial infarction of one kidney and contralateral nephrectomy was followed by a rapid and significant increase in blood pressure both in haired mice with a normal thymus function and in nude mice with genetical aplasia of the thymus. The level of blood pressure and the prognosis were not influenced by ...

Air embolization during machine preservation of kidneys for transplantation occurred in seven of 218 kidneys. In three it occured during transportation on a portable machine. On arrival they had warmed up and were discarded. In four kidneys air embolization occured in the laboratory and was detected immediately. Upon re-establishment of ...

An attempt has been made to show that there is still a need to evaluate screening for moderate hypertension (i.e. diastolic blood pressure equal or above 110 mm Hg). At present it has not been satisfactorily shown that treatment reduces mortality and morbidity. It is suggested that in the meantime ...

The simplest response to the question, what is the prevalence of hypertension in the United States today?, is given by a currently popular slogan: 23,000,000 Americans have hypertension. It is clear that the problem is large in scale, but this figure alone is an insufficient guide to many practical issues. ...

Prevalence rates of hypertension and its treatment in two population samples of middle-aged people, one in Albury and one in Melbourne, are described. On average, Italian-born subjects had lower pressures than their Australian-born neighbours. The proportions of Australian-born people in the two centres who had been previously diagnosed were respectively ...

In 31 patients undergoing surgery in treatment of hydronephrosis, peroperative pelvic pressure measurements were made. EMG records were taken from pelvis and ureter, and occasional measurements of urine flow were made. In 6 instances these studies were also made in the contralateral "normal" kidney, but in 2 of these patients ...

The prevalence of primary and secondary hypertension and of heart and kidney involvement was thoroughly studied in 689 hypertensive subjects derived from a blood pressure screening examination of a total population sample of Swedish men (n = 7,452). The prevalence of secondary hypertension was found to be only 5%, the ...

A recent survey of 8, 579 employed persons in New York City has revealed that 85.7 percent of the 1,440 hypertensives identified were already aware of their condition and 66.1 percent were being treated. These results are in marked contrast to those obtained only a few years ago, when in ...

During its "heart week" in February, 1975, the Danish Heart Foundation drew the attention of the public to the problem of heart-disease with special reference to high blood-pressure; and 24 377 people attending supermarkets in Copenhagen took advantage of an offer to have their blood-pressure checked. There was a small ...

Isometric handgrip (IHG) imposes an acutely increased afterload on the left ventricle. Utilizing systolic time intervals, we studied various responses to IHG, measured as changes from resting values with near-maximum IHG, in old normal (ON) subjects, young normal (YN) subjects, and old patients with hypertensive heart disease (HHD) and patients ...

The hydrostatic pressure, intrapelvic volume, and specific elasticity and strength of strips of tissue from the parenchyma and the pelvis of eight hydronephrotic kidneys were investigated and compared with the tissue characteristics of the pelvis of four control kidneys. Hydronephorsis manifested itself by a sixfold reduction of tissue strength, and ...

Of 15 594 high school students (ages, 15 to 20) whose blood pressure was measured in a screening program, 350 (2.2%) has hypertensive readings (150 mm Hg or more systolic, or 95 mm Hg or more diastolic, or both). The mean blood pressure for the boys was 125.0 plus or ...

Eighty intravenous pyelograms, carried out as part of the routine investigation of hypertension, revealed only one unsuspected renal lesion of possible relevance to the long-term management. Such a low therapeutic return, in the light of its cost and not entirely negligible risk, raises doubts about the place of excretion urography ...

A program linking detection to treatment was designed to improve blood-pressure control among adults with asymptomatic, uncomplicated hypertension. Key elements of this program were provision of all diagnostic and therapeutic services at work site, integration of delivery system with the administration of a labor union, adherence to rigid protocol, and ...

Isolated kidneys from both "post-salt" normotensive and hypertensive rats were perfused with blood from donor rats at varying pressures. At 130 mm Hg inflow pressure 15 "post-salt normotensive" kidneys put out 0.75 muEq Na/min/g kidney while 14 "post-salt hypertensive" kidneys put out 0.28 mu-Eq Na/min/g (P less than 0.001), a ...

The present appraisal indicates that blood pressure patterns in adolescence differ from those in adulthood and that the design of hypertension detection programs needs to be modified for this age group. Routine blood pressure screening within the school system would appear to be the most effective means for early detection ...

We evaluated past medical records and conducted a hypertension screening program in the outpatient clinic of a university hospital, a community hospital, and a city hospital, with the aid of specially trained high school students under the direction of a cardiovascular nurse. Fifty-one percent of the adult black outpatients had ...

Community-wide blood pressure screening is one of many methods of detecting unknown or inadequately treated hypertension. The first mass blood pressure screeing in a major metropolitan area was conducted in New Orleans on Aril 28 and 29, 1973. The 43 public and parochial schools were used as screening sites. Medical ...

Comparative measurements of intraocular pressure of 200 eyes were statistical analyzed. Goldmann applanation tonometry was performed by the author and was accepted as a reference system for the measurements made by a technician using the Pneumatonograph, the GlaucoTest screening tonometer, the Halberg tonometer and the Schiotz tonometer. The technician was ...

In two Edmonton shopping centres 9591 people were screened for hypertension: 3.3% were found to be normotensive but taking antihypertensive medication and another 8.8% were found to have elevated blood pressure. Systolic hypertension alone accounted for 45.3% of the hypertensive cases and diastolic hypertension, with or without systolic, for 54%. ...

Data obtained in long-term epidemiological studies of arterial blood pressure in the general population in South Wales were analysed to provide background information for the rational planning of screening programmes for hypertension.The incidence rates for cardiovascular complications emphasize the much greater prognostic value of blood pressure measurements in men than ...

The distribution of arterial blood pressure (BP) values of 1499 adult inhabitants of four Newfoundland communities was surveyed. Mean age- and sex-adjusted BP scores were found to be higher in each of three fishing villages than in the logging and mining community, Badger, in the central part of the province. ...

The physical and chemical processes involved in the functioning of the kidneys are reconsidered. It is shown that the transfer of fluid into the Bowman capsule of the nephrons is a gate transfer process and not a filtering process. The principle function of the kidneys is demonstrated as the control ...

An effective office organization for screening and follow-up of hypertensives can be simple. The physician must first adopt a policy of regularly taking blood pressures of patients who attend for any reason. Notations on the outside of the chart are a visible record and reminder. A tickler file with 12 ...

A 13 year review of a Hamilton, Ontario, family practice resulted in the detection of 607 hypertensive patients through case finding. By using a series of simple strategies, the measurement and recording of patients' blood pressures increased from 41% in 1965 to 98% in 1977. Team members now consistently measure ...

Detection and screening for hypertension in the work setting is becoming a focus of increased interest to business and health care professionals. An inexpensive, interactive computer program in the form of the tic-tac-toe game has been developed to motivate people to seek blood pressure evaluation. The focus of the game ...

Although family doctors may be reasonably effective in screening their patients for hypertension, some patients are missed. We examined the characteristics of patients screened and not screened for hypertension in a teaching family practice. Office visits were sampled during a one-month period. For non-hypertensives, the overall rate of patients whose ...

An attempt has been made to show that there is still a need to evaluate screening for moderate hypertension (i.e. diastolic blood pressure equal or above 110 mm Hg). At present it has not been satisfactorily shown that treatment reduces mortality and morbidity. It is suggested that in the meantime ...

1. Extracts of the rabbit's kidney injected into the rabbit cause a slight, increase in blood pressure which is barely more than that due to the mechanical effect of the injection. 2. Extracts of the dog's kidney injected into the dog cause a decided fall in pressure; an equal fall ...

In 1974 eight general practitioners decided to co-operate in a hypertension screening exercise in their practices. The reasons for the survey and the methodology are described and the results of screening over 28,000 patients are given. The cut-off point for normal diastolic blood pressure was 89 mmHg and 23,979 (85 ...

When some participants in a hypertension screening program reported a previous diagnosis or treatment of low blood pressure a similar program was established at two shopping centres in Montreal to identify and characterize subjects labelled as having low blood pressure. Of the 1019 subjects screened (434 men and 585 women) ...

As the initial step of a large randomized trial to test a new strategy of caring for hypertensive patients, the state of blood pressure screening was studied in 34 community-based family practices in southwestern Ontario. The charts of all active adult patients, 20-65 years of age, were reviewed.

The paper describes an instrument called an arterial tonometer which noninvasively and continuously monitors human blood pressure. It uses a special force-sensing piezoresistive transducer and a microprocessorbased electronic system to continuously obtain and display the blood pressure waveform on a CRT screen. The digital values of heart rate, systolic, diastolic, ...

1. Extracts of the rabbit's kidney injected into the rabbit cause a slight, increase in blood pressure which is barely more than that due to the mechanical effect of the injection. 2. Extracts of the dog's kidney injected into the dog cause a decided fall in pressure; an equal fall ...
