HIPERTENSAO ARTERIAL EM PACIENTES OBESOS COM HIPERTROFIA CARDIACA. EFEITOS DO CAPTOPRIL SOBRE A SENSIBILIDADE A INSULINA E HORMONIO DE CRESCIMENTO

Purpose. To evaluate the effects of captopril (Cpt) on carbohydrate metabolism and growth hormone (GH) in adults hypertensive obese patients with normal (NGT) or impaired (IGT) glucose tolerance and left ventricular hypertrophy. Methods. Ten patients (53 ± 8 years), 8 women and 2 men, white, body mass index (BMI) ≥ 26 kg/m2, left ventricular mass index (LVMI) > 135 g/m2 in man and > 110 g/m2 in woman, with diastolic blood pressure (DBP) 95-115 mmHg after 3 weeks of placebo, were identified by oral glucose tolerance test (OGTT-75 g) as either with NGT or IGT, and treated with Cpt 25 mg t.i.d. for 8 weeks. At the 8 weeks, dosage was increased to 50 mg b.i.d. if DBP > 90 mmHg or the decrease of the DBP < 10%, during the next 8 weeks. OGTT and clonidine tests (0,04 mg/kg) with determinations, every 30 minutes of glucose, insulin, and GH during 2 hours, were performed. Results. Cpt lowered SBP and DBP in the NGT group and IGT group. The LVMI and the left ventricular mass (LVM) decreased in the IGT group with no significant change in the NGT group. Cpt promoted in the IGT group decrease in the area under the curve (AUC) of glucose, and AUC of insulin, with increase of the AUC of the percent of the β cell function, AUC of HC, and insulin sensitivity index with no significantly change in the NGT group. Conclusion. Adults hypertensive obese patients with IGT had decreased significantly in mean fasting level of GH concentrations compared to age, race, and BMI matched hypertensive patients with NGT. Treatment with Cpt induced a significant increased of the GH, with improvement of the metabolism in patients with IGT.

Efetividade de um programa de exercícios no condicionamento físico, perfil metabólico e pressão arterial de pacientes hipertensos

Background and objective: It has been shown that aerobic exercise is useful to reduce arterial pressure, however, the effectiveness of an exercise program is still controversial and not very well analyzed among populations with low-income. The objective of the present study was to set up an individualized physical fitness program - Projeto Hipertensão - focused on hypertensive people, patients from a Health Basic Unit (HBU) and, after that, to investigate the effects of this program on physical fitness, metabolic profile and pressure levels. Methods: Sixteen hypertensive women (56 ± 3yrs) under regular pharmacological treatment underwent 4 months of a supervised aerobic and stretching exercise program (3 sessions/wk, 90 min/session, 60% of V̇O 2 max). Several physical and metabolic variables were compared before and after 4 months of training. Results: Training significantly reduced systolic arterial pressure (SAP, -6%), improved cardio-respiratory fitness (+42% of V̇O2max), flexibility (+11%) and plasma glucose content (-4%). BMI and % fat did not change. Besides modifying metabolic profile, it was found that training presented significant correlations between individual initial values of cholesterol total level (CT), high density lipoprotein (HDL-C) and low density lipoprotein (LDL-C) and its responses after exercise. Conclusions: The study shows that exercise programs can be personalized for hypertensive patients from a HBU and confirms the effectiveness of exercise on AP, physical fitness, flexibility and lipid profile on hypertensive patients. The expressive reduction of AP in hypertensive subjects suggests that this exercise intervention should be emphasized on other health centers which assist low-income population.

Análise da prescrição de medicamentos de pacientes hipertensos atendidos pelo SUS da rede municipal de saúde de Rincão - SP

The purpose of this study was to identify the drugs most often prescribed for hypertension at the Municipal Health Care Center of the town of Rincäo, State of São Paulo, Brazil, and the principal interactions arising from their association with other drugs, both anti-hypertensives and those in other classes. The study included 725 hypertensive patients registered at this health care center who were regularly seen by a physician every three months. Data were collected on age, sex, occurrence of diabetes, smoking, sedentary lifestyle and overweight, to obtain a profile of the hypertensive population of the area. Control records of all patients were available at the pharmacy in the health care center, where patients obtained their drugs once a month. Of the 725 patients, 38% were male and 62% female. Most (57%) were between 50 and 70 years of age, 21% used tobacco and 43% led a sedentary lifestyle. Single-drug therapy accounted for 33% of the prescriptions, multidrug therapy for 66%. In addition to anti-hypertensives, 50% of the patients took drugs of other therapeutic classes. Of those receiving multidrug therapy, 34% used three or more anti-hypertensives and 66% used only two of these drugs. Drug interactions were detected in as many as 47% of the prescriptions. Captopril was the drug that showed most interactions with others (54%), followed by hydrochlorothiazide (27%), furosemide (14%), propanolol (4%), and nifedipine (1%). The analysis revealed that drug consumption by the patients investigated is high, with a concomitantly high number of episodes of drug interaction.

Características da hipertensão arterial em Unidade Básica de Saúde

A cross observational study was achieved about hypertensive patients from the Basic Health Unit in Betel, Paulinia - S.P. assessing blood pressure levels, anthropometric data, biosocial variables, responses to questionaires about physical activity (Ipaq), and quality of life (Whoqol), as well as estimates of cardiovascular risk by Framingham score. With descriptive purposes, absolute and relative frequencies distributions are presented. From originally 95 people in the study, 18 were eliminated, and the remaining 77 were predominately composed by women, averaged 55.87 years old (standard deviation 11.88); white ethnic; basic schooling education, and income of 3 minimum salaries. Although clinical criteria verified altered values, it was the physical evaluation that indicated more clearly risks of contracting cardiovascular diseases, thus showing how different complementary evaluations can better predict risk. These results demonstrated that other professionals should be an asset as an integral part of the health team. © Copyright Moreira Jr. Editora. Todos os direitos reservados.

Nível de atividade física, comorbidades e idade de pacientes hipertensos

Physical inactivity is associated with chronic diseases in older adults. There are different domains of physical activity, such as leisure and locomotion. This study investigate the associations between different domains of physical activity, comorbidities and aging in hypertensive adults. Participants included 192 hypertensive respondents classified in groups of active and insufficiently active for leisure-time, locomotion, occupation and total time. They were stratified in age groups. Waist circumference was measured and comorbidities were self-reported. The chi-square test analyzed these associations; a one-way ANOVA compared the age groups (significance at p <0.05). The mean total time and occupational physical activity were lower for groups ages over 60 and 70 years, respectively. Occupational activity was associated with age in the female group, and with cholesterol and diabetes in males, who also had physical activity of locomotion associated with waist circumference. Physical activity of hypertensive patients is associated with comorbidities in different age groups and sex.

Avaliação da retinopatia hipertensiva através do potencial oscilatório do eletrorretinograma

OBJETIVO: Avaliar o comportamento do potencial oscilatório escotópico do eletrorretinograma de campo total (ERG) na retinopatia hipertensiva. MÉTODOS: Quarenta e quatro pacientes foram submetidos à avaliação clínica e subdivididos em dois grupos: 26 hipertensos (HT) com média de idade de 52,23 ± 5,79 anos divididos em 10 homens (38,46%) e 16 mulheres (61,54%) e 18 normotensos (NT) com média de idade de 51,79 ± 10,23 anos divididos em 5 homens (27,78%) e 13 mulheres (72,22%). Foram incluídos no estudo apenas hipertensos leves a moderados (estágio 1 e 2 respectivamente) sem lesões em outro órgão-alvo.Os pacientes hipertensos foram mantidos sob placebo durante o período do estudo. Em seguida, foram submetidos à avaliação oftalmológica e realização do ERG. O eletrorretinograma de campo total (ERG), com registro das respostas: escotópica, escotópica máxima, PO escotópico, fotópica e "flicker". Para análise da resposta do PO foi considerada a latência dos dois primeiros picos e o valor médio da amplitude dos três picos do complexo de três respostas consecutivas, denominado índice oscilatório (IO). RESULTADOS: A hipertensão arterial acometia 26 (59,1%) dos pacientes, ao passo que 18 (40,9%) eram normotensos. A média do IO obtido foi de 257,41µV no grupo de NT e de 217,81 µV no HT (p=0,006). As médias de latências obtidas para os picos 1 (NT-18,42 ms e HT-17,91 ms) e 2 (NT-24,54 ms e HT- 24,29 ms) não foram diferentes entre os grupos (p>0,05). CONCLUSÃO: Os hipertensos apresentam índice oscilatório significativamente menor que os normotensos, sugerindo que a hipertensão arterial pode ocasionar disfunção da retina interna.

Cuidado ao paciente com Doença Renal Crônica no nível primário: pensando a integralidade e o matriciamento

A Doença Renal Crônica é um problema de saúde pública crescente no mundo. A detecção e o tratamento precoces reduziriam as altas taxas de morbimortalidade e os custos associados. Este trabalho buscou identificar o panorama do acesso ao cuidado a partir da conduta dos médicos da Atenção Primária à Saúde na linha de cuidado da doença. Aplicaram-se questionários para 62 médicos de família dos Centros de Saúde da Família do município de Fortaleza. Os achados apontam que a Taxa de Filtração Glomerular foi mensurada por apenas 8.1% dos médicos para pacientes diabéticos e 4.8% para pacientes hipertensos. Mais da metade dos médicos (51.2%) referenciariam o paciente apresentando redução leve/moderada da Taxa de Filtração Glomerular ao nível secundário. Por outro lado, 25.8% dos médicos não referenciariam o paciente com Doença Renal Crônica avançada ao especialista. A lacuna entre esses dois níveis da atenção implica em barreira de acesso ao usuário, podendo comprometer avanços no plano da integralidade. A criação de novos dispositivos no processo de trabalho torna-se urgente e o apoio matricial apresenta-se como proposta viável para a articulação das ações entre os níveis da atenção no cuidado do portador da Doença Renal Crônica ou seus fatores de risco.

Outros benefícios do exercício físico para o hipertenso

Aerobic exercise has been suggested as a non-pharmacological treatment for hypertension, and the previous paper of this set demonstrated some of the physiological responses induced by exercise. It has been shown an increment on expenditures for appropriate hypertension management in both, public and private services, which reinforces the inclusion of preventive programs to reduce healthcare costs. However, little is known about physical exercise cost-effectiveness for hypertensive patients. There are several interventions like a simple doctor/dietitian counselling in order to change life style, wed-based nutrition program, pharmacological treatment and assisted or non-assisted physical exercise program that evaluate the costs savings. We have shown that regular exercise (combined or not with another diet counselling and antihypertensive treatment) may effectively contribute to reduce the health care costs (up to -38%). Also, we have shown that exercise improves body composition and lipid profile which are important risk factors to development of cardiovascular disease. So, exercise can lead to significant reduction in blood pressure medication use and, therefore, it causes cost savings, justifying the implementation of exercise programs in all healthcare units.

Influence of hypertension on oral infections and endodontic treatment

Hypertension is characterized by peripheral vascular resistancethat leads to blood pressure increase and severalsystemic changes that may negatively influence one s oralhealth. Thus, the aim of this study was to conduct a literaturereview on the influence of hypertension over oral conditionsand endodontic treatment. Hypertension mainly affects theblood vessels, brain and kidneys. A hypertensive conditioncan lead to increased levels of parathyroid hormones, abnormalvitamin D metabolism, reduction in the concentrationof ionized calcium and decreased calcium absorption.Therefore, hypertension can be closely associated with oralproblems such as periodontal diseases, implant loss, difficultyin bone healing, reduced salivary flow and protein concentrationin saliva, increased number of neutrophils and, as a consequence,favoring of inflammatory processes. It has alsobeen suggested that the success rate of endodontic treatmentin hypertensive patients is lower than in normotensiveones. The response of hypertensive patients to root canaltreatment, intracanal medications and sealers should be furtherstudied in order to provide knowledge on the changes,failures and success of endodontic treatment.

Plantas medicinais: indicação popular de uso no tratamento de hipertensão arterial sistêmica (HAS)

The aim of this study is to investigate the spontaneous use of medicinal plants by volunteer patients in the treatment of hypertension and to determine the most used plants in this situation. Data were collected through a questionnaire and a semi-structured guided interview applied to patients from a health center in the Midwest region of the state of Sao Paulo, Brazil. Quantitative analysis identified a high number of hypertensive patients spontaneously using herbal treatment. The referred plants were identified by the Herbarium Botu and researched in the literature as to their therapeutic actions. The biggest mistake was observed in the misuse of the Bilberry for the treatment of hypertension, which reveals that health professionals and the community in general should be more careful. As a result we have published an informative booklet, with emphasis on hypertension concepts and on the use of medicinal plants as an alternative therapy method for this disease in order to provide scientific knowledge and scientific research evidence to this practice.

Variáveis antropométricas e hemodinâmicas em relação a diferentes níveis e categorias de atividade física

This study aimed to investigate the relation between physical activity levels (PAL) of hypertensive patients, seeing different do- mains, and, to compare anthropometric variables and blood pressure (BP). The survey was conducted with 192 patients, mean age 63 ± 11 years. The anthropometric variables were body weight, body mass index (BMI) and waist circumference (WC). PAL was estimated using Baecke ́s questionnaire and categorized in four domains (OPA = occupational; leisure time = LTPA; locomotion = LPA and Total PA). Student t test unpaired was applied for comparisons between active and insufficiently active. Differences between active and sedentary in relation to anthropometry and resting blood pressure were observed for the LTPA, LPA and Total PA and significant negative correlations were observed between LPA and Total PA with systolic BP (p<0,05). Conclusion: the LPA and LTPA were associated with resting BP in hypertensive. No differences in BMI and WC among physically active and insuffi- ciently active were found.
