The purpose of this study was to determine the prevalence of persistent blood pressure elevations in an eighth-grade population composed of three ethnic groups, and to determine the feasibility of using school health facilities for hypertension screening. Blood pressure was recorded in 10,641 subjects (90% of the total eighth-grade population) in the Dallas Independent School District. Blacks made up 46% of the population; non-Latin whites, 40.1%; and Latin-Americans, 13.9%. On the first blood pressure screening, 8.9% had systolic or diastolic pressures or both at or above the 95th percentile. Of those whose blood pressures were elevated on the first examination, 98.3% were reexamined. After the third examination, 1.2% continued to have systolic hypertension, and 0.37% diastolic hypertension. No student had diastolic pressure above 90 mm Hg on all three examinations. The prevalence of persistent hypertension was similar for the three ethnic groups. Analysis of variation in blood pressure measurements revealed that the school nurses introduced a relatively small increase in variability. These data indicate that although school screening initially identifies large numbers of students as having inconstant pressure elevations, subsequent follow-up examinations show that less than 2% have persistent hypertension.

Arterial pressure was studied in 2,540 cattle-breeders (1289 men and 1251 women) living in three different climatogeographical zones of Mongolia. It was found that the mean values of arterial pressure in cattle-breeders living in alpine regions, both according to age groups and both sexes, were higher than those in cattle-breeders living in mountain regions of middle and low height. The number of cases with systolic, and diastolic hypertension as well as the number of persons with arterial pressure in the dangerous zone are significantly increased in the alpine region as compared to these data in the other regions. In alpine regions and in mountain regions of medium height in Mongolia, the incidence of hypertension among women is higher than that among men.

A long-term follow-up study was performed in 14 patients, operated for coarctation of the aorta in infancy. The median age at operation was 4 mth. Mean and median age at follow-up were 16 yr, and the follow-up time varied between 7 and 22 yr (mean and median 15 yr). At follow-up recoarctation was or had been present in 6 patients; there was no relation between the development of recoarctation and the age at operation. Concomitant aortic valve anomaly had been overlooked at the initial investigation in 3 patients. The systolic and diastolic blood pressure at follow-up was significantly elevated above the mean of normals; 2 of 8 patients without recoarctation clearly had diastolic hypertension. It seems as if even operation in infancy does not prevent hypertension later in childhood or adolescence in some of the patients, and it hardly seems justified to perform elective operations for coarctation of the aorta in infancy with the appreciable risk of recoarctation, until more long-term follow-up results are known. The patients should not be lost to follow-up.

This paper presents the results of a survey of the hypertensive patient population in a university family medicine practice to determine health beliefs, patient perceptions of the severity of their condition, stated levels of compliance to drug regimens, frequency of drug side effects, and frequency of physician discussions of drug side effects and diet. Health beliefs were then associated with diastolic hypertension and increase in medication dosage over a four-month period. Results of the survey sharpen the focus of patient education efforts by the family physician on specific attitudes, beliefs, and treatment issues which are most appropriate for the hypertensive patient. The physician may improve his/her management of hypertensive patients by: (1) anticipating prevalent myths and misconceptions which patients have concerning hypertension; (2) alleviating patient anxiety by stressing that control of blood pressure decreases the likelihood of complications; (3) effectively communicating to each patient the current status of his/her condition at each visit; and (4) initiating discussion of side effects through direct questioning for those effects most frequently seen.

Situations requiring immediate lowering of systemic blood pressure are infrequent. Certain clinical syndromes resulting from or complicated by severe hypertension demand vigorous, usually parenteral, antihypertensive therapy. Such syndromes include (1) diastolic hypertension accompanied by sudden disruption of cerebral function, (2) dissecting or leaking aortic aneurysm; (3) accelerated or malignant hypertension, (4) toxemia of pregnancy when either the fetus' or the mother's life is immediately threatened, (5) some instances of diastolic hypertension and acute left ventricular failure, (6) uncontrolled hypertension in the patient who requires emergency surgery, (7) refractory elevation of the diastolic pressure in the kidney transplant patient, and (8) refractory hypertension complicating myocardial infarction or angina. Drugs useful in acutely lowering blood pressure include diazoxide, sodium nitroprusside, methyldopa intravenously, reserpine intramuscularly, and trimethaphan camsylate intravenously. Use of furosemide reinforces the hypotensive effect of these agents. Theoretical advantages and disadvantages of these agents are not always encountered in clinical use.

Blood pressure measurements were obtained among 92,074 persons in Milwaukee between 1974 and 1976 by the Milwaukee Blood Pressure Program. Systolic hypertension was more prevalent in young white men than blacks below 25 years of age, was more common in middle-aged blacks than whites, and was equally prevalent among all persons past 65 years. Diastolic hypertension was more prevalent in blacks than whites of all ages. Whereas the prevalence of systolic hypertension in the population increased with age and was present in a majority or near majority of persons past 65 years, the prevalence of diastolic hypertension rose until the sixth decade, after which it declined. Hypertension was primarily of a diastolic variety in young blacks, whereas systolic hypertension was a prominent feature in young whites.

Hypertension has been observed to occur frequently in children with burns. In a series of children admitted to the St. Agnes Burn Treatment Center, sustained systolic and diastolic hypertension occurred in 31.5%, and 57.4% of the children demonstrated episodic periods of hypertension which were unsustained. The only clinical finding which significantly correlated with the hypertension was the presence of tachycardia, which persisted into the late healing phase of the thermal injury. Hypertension was more prevalent at younger ages. However, there was no other correlation of the development of hypertension with sex, race, or extent of thermal injury. The development of hypertension in itself did not worsen the prognosis for survival in the cases presented in this series. Possible pathogenic mechanisms which result in hypertension (elevated catecholamines, norepinephrine, renin secretion) are discussed.

Amongst a group of 819 children and adolescents aged between 10 and 18 years and attending a public school, the distribution of blood pressure was determined in relation to age, sex, height-weight ratio and family history. Mean blood pressure values increased with age both sexes for both systolic and diastolic levels. Children outside the norms, blood pressure 2SD, should be considered to be hypertensive and be followed up. The prevalence of systolic hypertension was 3.95 per cent amongst the boys and 3,83 per cent amongst girls. That for diastolic hypertension was 7.33 per cent for boys and 6.97 per cent for girls. Obesity appeared to be the major factor associated with hypertension since half of the hypertensive individuals were overweight. Individual prevention is thus possible. The existence of a family history of hypertension and of obesity more particularly in obese hypertensive children should lead to steps aimed at the familial prevention of hypertension.

The purpose of the study was to examine the value of regular measurements of plasma renin concentration (PRC) in selecting those chronic haemodialysis patients suitable for bilateral nephrectomy to prevent development of uncontrollable hypertension. Regular measurements of arterial blood pressure (BP) and PRC were performed during one year in 31 patients undergoing regular haemodialysis because of end-stage renal disease. Among 18 patients with PRC greater than or equal to 100 micro Goldblatt units per ml plasma (microGU/ml) systolic and/or diastolic hypertension persisted or developed in 12. In contrast, among 13 patients with PRC greater than 100microGU/ml, BP became normal in all but one, who had a slightly increased systolic BP. However, hypertension was mild and easily controlled by conventional therapy in all except one, who probably had an overlying volume-dependent hypertension. Therefore, bilateral nephrectomy was not necessary in any case. The results indicate that hypertension in the majority of chronic haemodialysis patients with high PRC can be adequately controlled without surgical intervention and that regular measurements of PRC have no practical value in forecasting the development of uncontrollable hypertension in chronic haemodialysis patients.

Abu Ghosh is an Israeli Moslem Arab village located 11 km west of Jerusalem. Its population of about 2,200 has a common ancestry and is highly inbred. Blood pressures, weights, heights and other pertinent data were recorded for 1,881 (93.3%) of 2,017 subjects aged two years and over who were available for study. Mean blood pressures in children up to the age of 15 years were similar to those reported elsewhere. Among adults, the prevalence of hypertension, especially diastolic hypertension, was high. The relative effects of genes and environment on familial similarity in blood pressures are discussed.
