Captopril does not Potentiate Post-Exercise Hypotension: A Randomized Crossover Study.

To evaluate whether captopril (3×50 mg/day) potentiates post-resistance exercise hypotension (PREH) in hypertensives (HT), 12 HT men received captopril and placebo for 4 weeks each in a double-blinded, randomized-crossover design. On each therapy, subjects underwent 2 sessions: Control (C - rest) and Resistance Exercise (RE - 7 exercises, 3 sets to moderate fatigue, 50% of 1 RM -repetition maximum). Measurements were taken before and after 30-60 min (Post1) and 7 h (Post2), and ambulatory blood pressure (BP) was monitored for 24 h. There were no differences in PREH characteristics and mechanisms between the placebo and captopril periods. At Post1, systolic/diastolic BP decreased significantly and similarly after RE with both therapies (Placebo=-13±2/-9±1 mmHg vs. Captopril=-12±2/-10±1 mmHg, P<0.05). RE reduced cardiac output in some subjects and systemic vascular resistance in others. Heart rate and cardiac sympathetic modulation increased, while stroke volume and baroreflex sensitivity decreased after RE (Placebo: +13±2 bpm, +21±5 nu, -11±5 ml, -4±2 ms/mmHg; Captopril: +13±2 bpm, +35±4 nu, 17±5 ml, -3±1 ms/mmHg, P<0.05). At Post2, all variables returned to pre-intervention values. Ambulatory BP was similar between the sessions. Thus, captopril did not potentiate the magnitude and duration of PREH in HT men, and it did not influence PREH mechanisms.

Home blood pressure monitoring in blood pressure control among haemodialysis patients: an open randomized clinical trial.

BACKGROUND: It is not known if the adjustment of antihypertensive therapy based on home blood pressure monitoring (HBPM) can improve blood pressure (BP) control among haemodialysis patients. METHODS: This is an open randomized clinical trial. Hypertensive patients on haemodialysis were randomized to have the antihypertensive therapy adjusted based on predialysis BP measurements or HBPM. Before and after 6 months of follow-up, patients were submitted to ambulatory blood pressure monitoring (ABPM) for 24 h, HBPM during 1 week and echocardiogram. RESULTS: A total of 34 and 31 patients completed the study in the HBPM and predialysis BP groups, respectively. At the end of study, the systolic (SBP) and diastolic (DBP) blood pressure during the interdialytic period measured by ABPM were significantly lower in the HBPM group in relation to the predialysis BP group (mean 24-h BP: 135 +/- 12 mmHg/76 +/- 7 mmHg versus 147 +/- 15 mmHg/79 +/- 8 mmHg; P < 0.05). In the HBPM analysis, the HBPM group showed a significant reduction only in SBP compared to the predialysis BP group (weekly mean: 144 +/- 21 mmHg versus 154 +/- 22 mmHg; P < 0.05). There were no differences between the HBPM and predialysis BP groups in relation to the left ventricular mass index at the end of the study (108 +/- 35 g/m(2) versus 110 +/- 33 g/m(2); P > 0.05). CONCLUSIONS: Decision making based on HBPM among haemodialysis patients has led to a better BP control during the interdialytic period in comparison with predialysis BP measurements. HBPM may be a useful adjuvant instrument for blood pressure control among haemodialysis patients.

[Prevalence of arterial hypertension in branch retinal vein occlusion patients]. / Prevalência de hipertensão arterial em pacientes com oclusão do ramo da veia central da retina.

PURPOSE: To identify in patients with branch retinal vein occlusion using ambulatory blood pressure monitoring and clinical blood pressure measures: hypertension prevalence, and nocturnal profile of blood pressure. METHODS: Prospectively, 93 eyes of 83 patients with branch retinal vein occlusion were submitted to ophthalmological examination. Afterwards the patients were submitted to clinical evaluation and blood pressure monitoring. Non-dipper was defined as a fall in systolic blood pressure

Oral Fludrocortisone Test for Salt-Sensitive Screening in Hypertensive Patients: A Randomized Crossover Trial.

BACKGROUND: Salt sensitivity is associated with an increased cardiovascular risk, but the gold standard method (diet cycles) requires 24-h urine samples and has poor patient compliance. OBJECTIVES: Test the hypothesis that oral fludrocortisone (0.4 mg per day for 7 days) is a good alternative in identifying salt-sensitive patients. METHODOLOGY: We conducted a randomized crossover study with 30 hypertensive individuals comprising the following steps: (1) washout; (2) phase A (low- and high-sodium diet cycles); (3) washout 2; (4) phase B (fludrocortisone test). Phase A and B steps were performed in a random way. Consistent with the literature, we found that 53.3% were salt-sensitive according to the reference test. Using the ROC curve, the fludrocortisone test defined salt sensitivity by a median blood pressure increase of ≥3 mmHg. A good accuracy of fludrocortisone in detecting salt sensitivity was observed (AUC: 0.732±0.065; p<0.001), with 80% sensitivity and 53% specificity. CONCLUSION: The fludrocortisone test is a good option for screening salt sensitivity in hypertensive patients. However, the low specificity prevents this test from being an ideal substitute to the labor-intensive diet cycles exam in the definition of salt sensitivity. This clinical trial is registered with NCT01453959.

Normal erythrocyte calpain I activity on membrane proteins under near-physiological conditions in patients with essential hypertension.

CONTEXT: It has been reported that the equilibrium between the erythrocyte protease calpain I and its physiological inhibitor calpastatin is disrupted in patients with essential hypertension. OBJECTIVE: To investigate the activity of non-purified calpain I in hemolysates against the erythrocytic membrane proteins, rather than against other substrates. DESIGN: Evaluation of calpain I red cell activity upon its own physiological substrates in hypertensive patients, in a near-physiological environment. SETTING: LIM-23 and LIM-40 of Hospital das Clinicas of the Faculty of Medicine of USP. SAMPLE: Patients with moderate primary hypertension over 21 years of age who were given amlodipine (n:10) and captopril (n:10) for 8 weeks, plus normal controls (n:10). MAIN MEASUREMENTS: Red cell membrane proteins were incubated with and without protease inhibitors and with and without calcium chloride and underwent polyacrylamide gel electrophoresis. RESULTS: Digestion of bands 2.1 and 4.1 was observed, indicating calpain I activity. No statistical differences regarding bands 2.1 and 4.1 were observed before treatment, between the controls and the hypertensive patients, either in ghosts prepared without calcium or with increasing concentrations of calcium. Nor were statistical differences observed after treatment, between the controls and the patients treated with amlodipine and captopril, or between the patients before and after treatment with both drugs. CONCLUSION: The final activity of non-purified calpain I upon its own physiological substrate, which was the approach utilized in this study, may more adequately reflect what happens in red cells. Under such conditions no imbalance favoring calpain I activity increase was observed. The protective factor provided by calpastatin against calpain I activity may diminish under hypertension.

Felypressin increases blood pressure during dental procedures in hypertensive patients.

BACKGROUND: Felypressin has been added to local anesthetic to increase the length of the anesthetic effect and reduce toxicity during dental procedures. However, the effect on blood pressure remains uncertain, and this may be highly relevant in the dental treatment of hypertensive patients. OBJECTIVE: To investigate the effect of felypressin on blood pressure in hypertensive patients with controlled BP. METHODS: 71 subjects with these characteristics and in need of periodontal treatment were studied. After 10 minutes of rest, local anesthesia (prilocaine) was infiltrated with and without addition of felypressin. Then, a deep subgingival scaling was performed. Blood pressure was measured by an automated oscillometric device (DIXTAL DX2010). Ten minutes after the administration of the anesthetic, peak anesthetic action was recorded. The State-Trait Anxiety Inventory (STAI) was used to assess the patients' trait anxiety. RESULTS: Systolic blood pressure increased after anesthesia, regardless of association with felypressin, throughout the dental procedure (p<0.05) and this response can be explained, at least in part, by the trait anxiety levels of the subjects. However, a further increase in diastolic blood pressure was observed when prilocaine was associated with felypressin (p<0.05), but this response did not change with trait anxiety levels. CONCLUSION: Felypressin increased the diastolic blood pressure of hypertensive patients with controlled blood pressure. Patients with high trait anxiety presented increases in systolic blood pressure upon some procedures, suggesting that an increase in blood pressure might also be related to fear or anxiety.

An economic evaluation of antihypertensive therapies based on clinical trials.

OBJECTIVE: Hypertension is a major issue in public health, and the financial costs associated with hypertension continue to increase. Cost-effectiveness studies focusing on antihypertensive drug combinations, however, have been scarce. The cost-effectiveness ratios of the traditional treatment (hydrochlorothiazide and atenolol) and the current treatment (losartan and amlodipine) were evaluated in patients with grade 1 or 2 hypertension (HT1-2). For patients with grade 3 hypertension (HT3), a third drug was added to the treatment combinations: enalapril was added to the traditional treatment, and hydrochlorothiazide was added to the current treatment. METHODS: Hypertension treatment costs were estimated on the basis of the purchase prices of the antihypertensive medications, and effectiveness was measured as the reduction in systolic blood pressure and diastolic blood pressure (in mm Hg) at the end of a 12-month study period. RESULTS: When the purchase price of the brand-name medication was used to calculate the cost, the traditional treatment presented a lower cost-effectiveness ratio [US$/mm Hg] than the current treatment in the HT1-2 group. In the HT3 group, however, there was no difference in cost-effectiveness ratio between the traditional treatment and the current treatment. The cost-effectiveness ratio differences between the treatment regimens maintained the same pattern when the purchase price of the lower-cost medication was used. CONCLUSIONS: We conclude that the traditional treatment is more cost-effective (US$/mm Hg) than the current treatment in the HT1-2 group. There was no difference in cost-effectiveness between the traditional treatment and the current treatment for the HT3 group.

How to avoid discontinuation of antihypertensive treatment: The experience in São Paulo, Brazil.

OBJECTIVES: To evaluate the importance of providing guidelines to patients via active telephone calls for blood pressure control and for preventing the discontinuation of treatment among hypertensive patients. INTRODUCTION: Many reasons exist for non-adherence to medical regimens, and one of the strategies employed to improve treatment compliance is the use of active telephone calls. METHODS: Hypertensive patients (n=354) who could receive telephone calls to remind them of their medical appointments and receive instruction about hypertension were distributed into two groups: a) "uncomplicated" - hypertensive patients with no other concurrent diseases and b) "complicated" - severe hypertensive patients (mean diastolic ≥ 110 mmHg with or without medication) or patients with comorbidities. All patients, except those excluded (n=44), were open-block randomized to follow two treatment regimens ("traditional" or "current") and to receive or not receive telephone calls ("phone calls" and "no phone calls" groups, respectively). RESULTS: Significantly fewer patients in the "phone calls" group discontinued treatment compared to those in the "no phone calls" group (4 vs. 30; p<0.0094). There was no difference in the percentage of patients with controlled blood pressure in the "phone calls" group and "no phone calls" group or in the "traditional" and "current" groups. The percentage of patients with controlled blood pressure (<140/90 mmHg) was increased at the end of the treatment (74%), reaching 80% in the "uncomplicated" group and 67% in the "complicated" group (p<0.000001). CONCLUSION: Guidance to patients via active telephone calls is an efficient strategy for preventing the discontinuation of antihypertensive treatment.

Betabloqueio com atenolol não reduz potência aeróbia nem muda limiares ventilatórios em hipertensos sedentários / Atenolol beta-block does not decrease aerobic power or alter ventilatory thresholds in sedentary hypertensive subjects

INTRODUÇÃO: O exercício aeróbio é recomendado para o tratamento da hipertensão. Sua intensidade pode ser prescrita com base na porcentagem da frequência cardíaca máxima (%FCmáx) ou no consumo pico de oxigênio (%VO2pico) em que os limiares ventilatórios (LV) são alcançados. Entretanto, alguns hipertensos que iniciam o treinamento podem estar tomando betabloqueadores, o que pode influenciar esses parâmetros. OBJETIVO: verificar os efeitos do atenolol sobre os LV de hipertensos sedentários. MÉTODOS: Nove voluntários realizaram dois testes ergoespirométricos máximos após quatro semanas de tratamento com atenolol (25 mg administrado por via oral duas vezes por dia) e com placebo, administrados em ordem fixa e de forma cega. Durante os testes, a frequência cardíaca (FC), a pressão arterial (PA) e o VO2 no repouso, limiar anaeróbio (LA), ponto de compensação respiratória (PCR) e pico do esforço foram analisados. RESULTADOS: O VO2 aumentou progressivamente no exercício e seus valores foram semelhantes nos dois tratamentos. A PA sistólica e a FC também aumentaram no exercício, mas seus valores absolutos foram significativamente menores com o atenolol. Porém, o aumento da PA sistólica e da FC no exercício foi semelhante com os dois tratamentos. Assim, o percentual da FCmáx e o percentual do VO2pico em que LA e PCR foram alcançados não diferiram entre o placebo e o atenolol. CONCLUSÃO: O atenolol na dosagem de 50 mg/dia não afetou o percentual do VO2pico e da FCmáx em que os LV são atingidos, o que confirma que a prescrição de intensidade de treinamento com base nessas porcentagens pode ser mantida em hipertensos que recebem betabloqueadores.

INTRODUCTION: Aerobic exercise is recommended for the treatment of hypertension. Its intensity can be prescribed based on the percentage of maximum heart rate (% MHR) or peak oxygen consumption (VO2peak%) in which the ventilatory thresholds (VT) are achieved. However, some hypertensive patients who begin aerobic training may be receiving beta-blockers, which can influence these parameters. OBJECTIVE: To investigate the effects of atenolol on VT of sedentary hypertensive patients. METHODS: Nine volunteers performed two cardiopulmonary exercise tests until exhaustion after 4 weeks of treatment with atenolol (25 mg orally twice daily) and with placebo, administered in a fixed order and in a blinded manner. During the tests, heart rate (HR), blood pressure (BP), VO2 at rest, anaerobic threshold (AT), respiratory compensation point (RCP) and peak effort were analyzed. RESULTS: VO2 increased progressively throughout the exercise and the values were similar for both treatments. Systolic blood pressure and heart rate also increased progressively during the exercise, but their absolute values were significantly lower with atenolol. However, the increase in systolic BP and HR during exercise was similar in both treatments. Thus, the % of MHR and %VO2peak at which LA and PCR were achieved were not different between placebo and atenolol. CONCLUSION: Atenolol, at a dosage of 50mg/day, did not affect the % of VO2peak and % of MHR corresponding to the VTs, which confirms that prescription of training intensity based on these percentages is adequate to hypertensive patients receiving beta-blockers.

Felipressina aumenta pressão arterial durante procedimento odontológico em pacientes hipertensos / Felypressin increases blood pressure during dental procedures in hypertensive patients

FUNDAMENTO: A felipressina foi adicionada ao anestésico local para aumentar a duração do efeito anestésico e reduzir a toxicidade nos procedimentos dentários. No entanto, o efeito sobre a pressão arterial é incerta, e isso pode ser altamente relevante no tratamento dentário de pacientes hipertensos. OBJETIVO: Investigar o efeito da felipressina sobre a pressão arterial em pacientes hipertensos com pressão arterial controlada. MÉTODOS: Foram estudados 71 indivíduos com essas características e com necessidade de tratamento periodontal. Após 10 minutos de repouso, a anestesia local (prilocaína) foi infiltrada com e sem adição de felipressina. Em seguida, uma raspagem subgengival profunda foi realizada. A pressão arterial foi medida por um equipamento oscilométrico automático (DIXTAL DX2010). Dez minutos após a administração do anestésico, o pico de ação anestésica foi gravado. O Inventário de Ansiedade Traço-Estado (IDATE) foi utilizado para avaliar o traço de ansiedade nos pacientes. RESULTADOS: A pressão arterial sistólica aumentou após a anestesia, independentemente da associação com felipressina, durante todo o procedimento dentário (p < 0,05), e essa resposta pode ser explicada, pelo menos em parte, pelos níveis de traço de ansiedade dos indivíduos. No entanto, um aumento adicional na pressão arterial diastólica foi observado quando a prilocaína foi associada a felipressina (p < 0,05), mas essa resposta não se alterou com os níveis de traço de ansiedade. CONCLUSÃO: A felipressina aumentou a pressão arterial diastólica de pacientes hipertensos com pressão arterial controlada. Pacientes com traço de ansiedade elevado apresentaram aumento na pressão arterial sistólica em alguns procedimentos, sugerindo que um aumento da pressão arterial também pode estar relacionado ao medo ou à ansiedade.

There was no difference in cost-effectiveness between the traditional treatment and the current treatment for the HT3 group.

Aftereffects of exercise and relaxation on blood pressure.

OBJECTIVE: To study the acute aftereffects of exercise and relaxation, performed alone and in combination, on blood pressure (BP) measured at baseline and during stressful conditions. DESIGN: Clinical trial with comparison of groups and repeated measures in each group. SETTING: Exercise Hemodynamic Laboratory, University of São Paulo, Brazil. PARTICIPANTS: Fourteen normotensive (NT) and 16 essential hypertensive (HT) subjects. INTERVENTIONS: Four random experimental sessions: relaxation (RX-20 min); exercise [EX-cycle ergometer, 53 min, 50% peak oxygen uptake (VO2peak)]; exercise plus relaxation (EX+RX); and control (C-73 min rest). Measures were taken before and after interventions at baseline and during Stroop color test. MAIN OUTCOME MEASURES: Auscultatory and plesthysmographic BPs. RESULTS: Systolic and diastolic BPs decreased significantly after all the interventions. The decreases in both BPs were significantly greater after the EX+RX session, and were also greater in the HT (EX+RX session, -10+/-1/-7+/-1 and -15+/-2/-8+/-1 mm Hg for the NT and HT, respectively). During mental stress, systolic BP increased significantly and similarly after all the experimental sessions. Diastolic BP also increased significantly during stress; however, the increase was significantly greater after the RX session. At the end of the mental stress, diastolic BP was significantly lower after the EX (74+/-3 mm Hg) and EX+RX (72+/-3 mm Hg) sessions than after the C (79+/-3 mm Hg) and RX (78+/-3 mm Hg) sessions. CONCLUSIONS: In NT and HT subjects, a single bout of exercise or relaxation has hypotensive effects, further enhanced by their combination, and greater in the HT. Moreover, exercise performed alone or in combination with relaxation decreases systolic and diastolic BPs during mental stress.

CONCLUSION: Guidance to patients via active telephone calls is an efficient strategy for preventing the discontinuation of antihypertensive treatment.

Pré-hipertensão: conceito, epidemiologia e o que falam as diretrizes / Prehypertension: concept, epidemiology and what the guidelines say

A pressão arterial, como qualquer outra variável fisiológica, tem distribuição normal entre a população. Há uma relação contínua entre pressão arterial e doença cardiovascular, mas não há um valor-limite que separe os pacientes hipertensos que terão um evento cardiovascular futuro daqueles que não o terão. O risco de doença cardiovascular depende da pressão arterial, dos fatores de risco coexistentes e da existência de lesões em órgãos-alvo. O Seventh Joint National Committee (JNC 7) reuniu indivíduos com pressão arterial normal e normal-alta em único grupo, denominado “pré-hipertensão”. Nessa diretriz, a pré-hipertensão é considerada um precursor da hipertensão estágio 1 e índice prognóstico de risco cardiovascular. O estudo inicial deFramingham, porém, assim como as Diretrizes Europeias e Brasileiras de Hipertensão, não sustenta a ideia de rotular indivíduos com pressão arterial normal como sendo pré-hipertensos. A questão-chave que permanece sem resposta é se indivíduos com pressão arterial normal-alta devem ser tratados farmacologicamente antes que progridam para hipertensão. Sabemos que a elevação da pressão arterial representa um fator de risco independente, linear e contínuo para os pacientes, que podem ser vitimados por doenças cardiovasculares.

Blood pressure, like any physiological variable, is normally distributed in the population. There is a continuous relation between blood pressure and cardiovascular disease, but no clear threshold value separates hypertensive patients who will experience future cardiovascular events from those who will not. The risk of cardiovascular disease depends on blood pressure, coexistent risk factors, and whether there is hypertensive damage to target organs. The JNC 7 guidelines combined subjects with normal and high-normal blood pressure into a single group called“ prehypertension”. In this guideline, prehypertension is considered a precursor of stage 1 hypertension and a predictorof excessive cardiovascular risk. However, the initial Framingham study, European and Brazilian hypertension guidelines do not support the idea of labeling subjects with normal blood pressure as being prehypertensive. The key question whether subjects with high-normalblood pressure should be pharmacologically treated beforet hey progress to hypertension remains unanswered. Life-style measures can reduce blood pressure and may prove useful in those with high normal/prehypertension blood pressures

Adesão ao tratamento em hipertensão arterial sistólica isolada: [revisão] / Adhesion to the treatment in systolic hypertension: [review]

O arsenal terapêutico para doenças crônicas, como hipertensão arterial, recebe frequentemente novos medicamentos. Entretanto, mesmo com todo esse investimento, quem trata de pacientes com essas condições continua esbarrando em um problema secular, a falta de adesão à terapêutica, seja ela medicamentosa ou não. Em relação à hipertensão arterial sistólica isolada garantir a adesão é ainda mais difícil, porque é condição relacionada à faixa etária mais avançada. Neste grupo de pacientes, vários fatores agem para levar a pior adesão, desde limitações do paciente, necessidade de cuidadores e prescrições com muitos itens. Abordar o tema adesão em pacientes com essas peculiaridades requer visão individualizada, mas multiprofissional.

New drugs frequently enlarge therapeutic arsenal for chronic illnesses as hypertension. Despite all this investment, who deals with patients with these conditions, continues with a secular problem, the lack of adhesion to prescription. With regard to the systolic hypertension, to guarantee the adhesion is still more difficult because this condition is far more common in elderly. In this group of patients some factors act to take to worse adhesion, since patient’s limitations, caregivers’ need and a great number of medications. To approach the adhesion in patients with these peculiarities requires a differentiated view, but multiprofessional.
