OBJECTIVE: To compare blood pressure measurements taken at home by physicians, nurses, and patients with office blood pressure measurement , ambulatory blood pressure monitoring and home blood pressure measurement. METHODS: A total of 44 patients seen by a home care program were studied. Protocol 1 a) blood pressure was measured by the patient, a physician and a nurse during a regular home visit (Home1); b) home blood pressure measurement was measured for 4 days (HBPM1); c) office blood pressure measurement was measured by a physician, a nurse, and the patient; and by 24-hour ambulatory blood pressure monitoring. Protocol 2 blood pressure was measured by the patient, a physician, and a nurse during a special home visit in the presence of a physician and a nurse only (Home2); and b) home blood pressure measurement was taken for the second time (HBPM2). Echocardiography, guided by a two-dimensional echocardiograph, was performed. RESULTS: Protocol 1: a) office blood pressure measurement and Home1 were significantly higher than ambulatory blood pressure monitoring, except for systolic and diastolic office blood pressure measurement taken by the patient or a family member, systolic blood pressure taken by a nurse, and diastolic blood pressure taken by a physician. b) ambulatory blood pressure monitoring and HBPM1 were similar. Protocol 2: a) HBPM2 and Home2 were similar. b) Home2 was significantly lower than Home1...

INTRODUCTION: Ambulatory blood pressure monitors have been used in salt loading and depletion protocols. However, the agreement between measurements made using ambulatory blood pressure monitors and those made with the sphygmomanometer has not been evaluated. OBJECTIVE: The objective of this study was to compare the concordance of the two methods of blood pressure measurements in protocols of acute salt loading and depletion. METHOD: Systolic blood pressure was measured using a sphygmomanometer at the completion of salt infusion (2 L NaCl 0.9%, 4 h) and salt depletion (furosemide, 120mg/day, p.o.) in 18 volunteers. Using the Pearson correlation coefficient (ρ), these readings were compared with the mean systolic blood pressure measured using the ambulatory blood pressure monitoring device during the following periods: 4 h of saline infusion and 12 h of salt depletion; 4 h of saline infusion and the last 6 h of salt depletion; 12 h of salt loading and the last 6 h of depletion; 12 h of salt loading and 12 h of depletion. Salt sensitivity was defined by a difference in the systolic blood pressure between salt loading and salt depletion greater than 10 mmHg when measured with the sphygmomanometer, and the Kappa analysis of concordance (K) was used with a significance level of P<0.05. RESULTS: Only the blood pressure readings obtained using the ambulatory blood pressure device during 4 h of intravenous NaCl and during 12 h of salt depletion showed a high correlation with the variation in the systolic blood pressure measured by the sphygmomanometer...

O exercício resistido dinâmico é recomendado, em complemento ao aeróbico, para indivíduos hipertensos. O aumento da pressão arterial durante sua execução se faz, primordialmente, pelo aumento da resistência vascular periférica, porém o aumento do débito cardíaco também parece estar envolvido. A elevação da pressão arterial parece ser exacerbada em hipertensos não medicados. Entretanto, grande parte dos hipertensos está sob terapêutica medicamentosa e vários fazem uso de -bloqueadores, que reduzem o débito cardíaco pela diminuição da resposta taquicárdica e inotrópica à estimulação simpática. Assim, é possível supor que o uso de -bloqueadores reduza o aumento da pressão arterial nos exercícios resistidos. Porém, pelo nosso conhecimento, este efeito ainda não foi estudado. Assim, esta investigação teve por objetivo investigar o efeito do atenolol sobre a resposta da pressão arterial durante o exercício resistido de diferentes intensidades. Foram estudados 10 hipertensos essenciais com pressão arterial sistólica/diastólica sob placebo entre 140 e 160/90 e 105 mmHg. Os pacientes foram estudados após 6 semanas de uso de placebo e de atenolol, sendo que os indivíduos estavam cegos para a medicação. Em cada fase...

Study design: Association study Objective: To analyze the association between different biological/behavioral risk factors and blood pressure in a sample of type 2 diabetes mellitus patients with poor glycemic control. Methods: A sample of 121 type 2 diabetic patients was selected in the Public Healthcare System in a middle size Brazilian city. Blood pressure was measured using an aneroid device, previously calibrated. Six determinants of blood pressure were taken into count: age, hypoglycemic agents, general obesity, abdominal obesity, eating behaviors and physical activity level. Results: The type 2 diabetic patients presented mean age of 60.1±8.9 years-old and, at least, one risk factor. Eating behaviors (OR adj= 0.31 [0.12-0.75]) and sports practice (OR adj= 0.12 [0.02-0.75]) constituted protective factors associated with lower systolic blood pressure. On the other hand, age was positively associated with high systolic blood pressure (OR adj= 3.81 [1.39-10.38]). Patients with 5-6 risk factors, presented higher values of systolic and (F= 3.857; p= 0.011 [post hoc with p= 0.039]), diastolic blood pressure (F= 4.158; p= 0.008 [post hoc with p= 0.036]) and increased occurrence of hypertension (p= 0.010). Conclusion: Our findings indicate that...

Small size at birth has been associated with increased blood pressure in adult men and women. In rats, isocaloric protein restriction reduces fetal growth and increases systolic blood pressure in adult offspring. Balanced maternal undernutrition in the rat also increases adult blood pressure, but not consistently. The aim of this study was to determine the effect of moderate balanced maternal undernutrition (85% of ad libitum intake from 4 weeks before, and throughout pregnancy) on blood pressure of adult offspring in the guinea pig, a species that is relatively mature at birth. Blood pressure was measured in chronically catheterised offspring of ad libitum fed or feed-restricted mothers, at 3 months of age (young adult). Maternal feed restriction reduced birth weight (_17%) and increased systolic blood pressure (+9%, P < 0.03) in young adult male offspring. In offspring of ad libitum fed and feed-restricted mothers, combined data showed that systolic blood pressure and mean arterial pressure correlated negatively with head width at birth (P = 0.02 and P = 0.04, respectively, n = 28). Systolic blood pressure also correlated negatively with birth weight and the ratio birth weight/birth length, but only in offspring of ad libitum fed mothers (P = 0.04 and P = 0.03...

The cause of ethnic differences in cardiovascular disease remains a scientific challenge. Blood pressure tracks from late childhood to adulthood. We examined ethnic differences in changes in blood pressure between early and late adolescence in the United Kingdom. Longitudinal measures of blood pressure, height, weight, leg length, smoking, and socioeconomic circumstances were obtained from London, United Kingdom, schoolchildren of White British (n=692), Black Caribbean (n=670), Black African (n=772), Indian (n=384), and Pakistani and Bangladeshi (n=402) ethnicity at 11 to 13 years and 14 to 16 years. Predicted age- and ethnic-specific means of blood pressure, adjusted for anthropometry and social exposures, were derived using mixed models. Among boys, systolic blood pressure did not differ by ethnicity at 12 years, but the greater increase among Black Africans than Whites led to higher systolic blood pressure at 16 years (+2.9 mm Hg). Among girls, ethnic differences in mean systolic blood pressure were not significant at any age, but while systolic blood pressure hardly changed with age among White girls, it increased among Black Caribbeans and Black Africans. Ethnic differences in diastolic blood pressure were more marked than those for systolic blood pressure. Body mass index...

Objective: To determine the accuracy of using systolic and diastolic blood pressure, mean arterial pressure, and increase of blood pressure to predict pre-eclampsia. Design: Systematic review with meta-analysis of data on test accuracy. Data sources: Medline, Embase, Cochrane Library, Medion, checking reference lists of included articles and reviews, contact with authors. Review methods: Without language restrictions, two reviewers independently selected the articles in which the accuracy of blood pressure measurement during pregnancy was evaluated to predict pre-eclampsia. Data were extracted on study characteristics, quality, and results to construct 2×2 tables. Summary receiver operating characteristic curves and likelihood ratios were generated for the various levels and their thresholds. Results: 34 studies, testing 60 599 women (3341 cases of pre-eclampsia), were included. In women at low risk for pre-eclampsia, the areas under the summary receiver operating characteristic curves for blood pressure measurement in the second trimester were 0.68 (95% confidence interval 0.64 to 0.72) for systolic blood pressure, 0.66 (0.59 to 0.72) for diastolic blood pressure, and 0.76 (0.70 to 0.82) for mean arterial pressure. Findings for the first trimester showed a similar pattern. Second trimester mean arterial pressure of 90 mm Hg or more showed a positive likelihood ratio of 3.5 (95% confidence interval 2.0 to 5.0) and a negative likelihood ratio of 0.46 (0.16 to 0.75). In women deemed to be at high risk...

BACKGROUND: Twenty-four hour ambulatory blood pressure thresholds have been defined for the diagnosis of mild hypertension but not for its treatment or for other blood pressure thresholds used in the diagnosis of moderate to severe hypertension. We aimed to derive age and sex related ambulatory blood pressure equivalents to clinic blood pressure thresholds for diagnosis and treatment of hypertension. METHODS: We collated 24 hour ambulatory blood pressure data, recorded with validated devices, from 11 centres across six Australian states (n=8575). We used least product regression to assess the relation between these measurements and clinic blood pressure measured by trained staff and in a smaller cohort by doctors (n=1693). RESULTS: Mean age of participants was 56 years (SD 15) with mean body mass index 28.9 (5.5) and mean clinic systolic/diastolic blood pressure 142/82 mm Hg (19/12); 4626 (54%) were women. Average clinic measurements by trained staff were 6/3 mm Hg higher than daytime ambulatory blood pressure and 10/5 mm Hg higher than 24 hour blood pressure, but 9/7 mm Hg lower than clinic values measured by doctors. Daytime ambulatory equivalents derived from trained staff clinic measurements were 4/3 mm Hg less than the 140/90 mm Hg clinic threshold (lower limit of grade 1 hypertension)...

BACKGROUND: Blood pressure targets in individuals treated for hypertension in primary care remain difficult to attain. AIMS: To assess the role of practice nurses in facilitating intensive and structured management to achieve ideal BP levels. METHODS: We analysed outcome data from the Valsartan Intensified Primary carE Reduction of Blood Pressure Study. Patients were randomly allocated (2:1) to the study intervention or usual care. Within both groups, a practice nurse mediated the management of blood pressure for 439 patients with endpoint blood pressure data (n=1492). Patient management was categorised as: standard usual care (n=348, 23.3%); practice nurse-mediated usual care (n=156, 10.5%); standard intervention (n=705, 47.3%) and practice nurse-mediated intervention (n=283, 19.0%). Blood pressure goal attainment at 26-week follow-up was then compared. RESULTS: Mean age was 59.3±12.0 years and 62% were men. Baseline blood pressure was similar in practice nurse-mediated (usual care or intervention) and standard care management patients (150 ± 16/88 ± 11 vs. 150 ± 17/89 ± 11 mmHg, respectively). Practice nurse-mediated patients had a stricter blood pressure goal of ⩽125/75 mmHg (33.7% vs. 27.3%, p=0.026). Practice nurse-mediated intervention patients achieved the greatest blood pressure falls and the highest level of blood pressure goal attainment (39.2%) compared with standard intervention (35.0%)...

Excess salt intake increases blood pressure particularly during states of hyperinsulinism and insulin resistance. Insulin is presumably effective through activation of ENaC. Excess salt intake further decreases peripheral glucose uptake thus impairing glucose tolerance. Stimulation of both, the epithelial Na+ channel ENaC and of cellular glucose uptake involves phosphatidylinositide 3-kinase (PI-3K) which signals through protein kinase B (Akt/PKB) and all three members of the serum and glucocorticoid inducible kinase (SGK) family of kinases SGK1, SGK2 and SGK3. All three kinases have been previously shown to modify a variety of transporters including ENaC and the glucose transporter SGLT1. To explore the role of SGK1 in salt sensitive hypertension and peripheral glucose uptake, experiments were performed in male or female SGK1 knockout mice (sgk1-/-) and their wild type littermates (sgk1+/+) which were subjected to standard diet, high-fat diet, high fructose diet or dexamethasone treatment and allowed free access to either tap water (control-salt) or 1% saline (high-salt). Under control diet fluid intake, blood pressure, urinary flow rate and urinary Na+, K+, Cl- excretion were similar in sgk1-/- and sgk1+/+mice, plasma aldosterone concentration was however significantly higher in sgk1-/- (1.22 ± 0.18 ng/ml) than in sgk1+/+mice (0.57 ± 0.11 ng/ml). Under standard diet...

INTRODUÇÃO: A hipertensão arterial é um grave problema de saúde pública, que atinge cerca de 600 milhões de pessoas e constitui um dos fatores de risco de maiores morbidade e mortalidade mundiais. A medida de pressão arterial tem sido algo preocupante em pesquisas já realizadas em serviços de saúde, pois sua operacionalização esbarra em muitas dificuldades dentro da prática clínica. Sabe-se o quanto a técnica de medida de Pressão Arterial (PA) apurada é necessária para diagnosticar a Hipertensão Arterial (HA), pois, apesar de ser um procedimento fácil, há necessidade de que os profissionais sejam criteriosos em sua aplicação, executando-o de maneira adequada. A aquisição de competências e habilidades relacionadas a essa técnica durante a graduação é fundamental, já que a mesma é presente no cotidiano do processo de trabalho do enfermeiro. OBJETIVOS: avaliar o desenvolvimento de competências e habilidades relacionadas à medida auscultatória de pressão arterial na visão de docentes e discentes de uma universidade pública do interior paulista e analisar a colaboração de cada disciplina no desenvolvimento de habilidades e competências para a realização da medida de pressão arterial, conforme expresso em seus programas de ensino; verificar como os docentes avaliam as competências e as habilidades dos estudantes...

This thesis presents studies relating to the role of the gastrointestinal tract in postprandial blood pressure regulation. The areas that have been addressed include : ( i ) the methodological approaches to the evaluation of gastric emptying, blood pressure, splanchnic blood flow, intraluminal manometry and gut hormones and ( ii ) the pathophysiological mechanisms underlying postprandial hypotension, with a particular focus on ' gastric ' and ' small intestinal ' mechanisms and their potential therapeutic relevance. All of the studies have been either published or manuscripts have been prepared for publication. While scintigraphy represents the ' gold standard ' for the measurement of gastric emptying, recent studies suggest that three - dimensional ( 3D ) ultrasonography may also allow a precise measure of gastric emptying. Concurrent scintigraphic and ultrasonographic measurements of gastric emptying of liquids were performed in healthy young volunteers. There was a good correlation and agreement between scintigraphic measurements of gastric emptying and 3D ultrasonography after ingestion of both low - and high - nutrient drinks, indicating that 3D ultrasonography, provides a valid measure of gastric emptying of liquid meals in normal subjects. Postprandial hypotension...

BACKGROUND: Even with anti-hypertensive therapy, it is difficult to maintain optimal systemic blood pressure values in hypertensive patients. Exercise may reduce blood pressure in untreated hypertensive, but its effect when combined with long-term anti-hypertensive therapy remains unclear. Our purpose was to evaluate the acute effects of a single session of aerobic exercise on the blood pressure of long-term-treated hypertensive patients. METHODS: Fifty treated hypertensive patients (18/32 male/female; 46.5±8.2 years; Body mass index: 27.8±4.7 kg/m²) were monitored for 24 h with respect to ambulatory (A) blood pressure after an aerobic exercise session (post-exercise) and a control period (control) in random order. Aerobic exercise consisted of 40 minutes on a cycle-ergometer, with the mean exercise intensity at 60% of the patient's reserve heart rate. RESULTS: Post-exercise ambulatory blood pressure was reduced for 24 h systolic (126±8.6 vs. 123.1±8.7 mmHg, p=0.004) and diastolic blood pressure (81.9±8 vs. 79.8±8.5 mmHg, p=0.004), daytime diastolic blood pressure (85.5±8.5 vs. 83.9±8.8 mmHg, p=0.04), and nighttime S (116.8±9.9 vs. 112.5±9.2 mmHg, p<0.001) and diastolic blood pressure (73.5±8.8 vs. 70.1±8.4 mmHg, p<0.001). Post-exercise daytime systolic blood pressure also tended to be reduced (129.8±9.3 vs. 127.8±9.4 mmHg...

OBJECTIVE: to evaluate the prevalence of high blood pressure in fat or overweight children and adolescents and its associated factors. METHODS: Cross-sectional study including 200 children and adolescents between two and 18 years old. It was measured the abdominal circumference, blood pressure, weight and height. The systolic and diastolic blood pressure were considered high when equal or higher than 90th percentile. The value of the blood pressure in the 25th, 50th and 75th percentiles were described according to age groups, sex, nutritional state and abdominal circumference. To check the association between high blood pressure and clinical variables it was used qui-square tests and a significant level of 5%. RESULTS: The majority of children and adolescents (70.5 %) had high blood pressure: 6% showed an increase only in the systolic blood pressure, 33% in diastolic blood pressure and 31.5 % in both. Systolic blood pressure values were higher observed in individuals with severe obesity and increased waist circumference, as well as those of the male sex and in the group of adolescents. Among those who had high blood pressure, the normal maximum limit of the systolic blood pressure was observed in the 50th percentile and for the diastolic in the 75th percentile. The high systolic blood pressure was associated with adolescents with severe obesity. CONCLUSION: The high prevalence of high blood pressure observed in this study indicates the need to implement policies and actions oriented towards the prevention and control of obesity and its co-morbidities...

OBJECTIVE: To compare blood pressure measurements taken at home by physicians, nurses, and patients with office blood pressure measurement , ambulatory blood pressure monitoring and home blood pressure measurement. METHODS: A total of 44 patients seen by a home care program were studied. Protocol 1 a) blood pressure was measured by the patient, a physician and a nurse during a regular home visit (Home1); b) home blood pressure measurement was measured for 4 days (HBPM1); c) office blood pressure measurement was measured by a physician, a nurse, and the patient; and by 24-hour ambulatory blood pressure monitoring. Protocol 2 blood pressure was measured by the patient, a physician, and a nurse during a special home visit in the presence of a physician and a nurse only (Home2); and b) home blood pressure measurement was taken for the second time (HBPM2). Echocardiography, guided by a two-dimensional echocardiograph, was performed. RESULTS: Protocol 1: a) office blood pressure measurement and Home1 were significantly higher than ambulatory blood pressure monitoring, except for systolic and diastolic office blood pressure measurement taken by the patient or a family member, systolic blood pressure taken by a nurse, and diastolic blood pressure taken by a physician. b) ambulatory blood pressure monitoring and HBPM1 were similar. Protocol 2: a) HBPM2 and Home2 were similar. b) Home2 was significantly lower than Home1...
