ABSTRACT Introduction: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a powerful predictor of perioperative outcomes. We evaluated the burden of CSA-AKI in patients with preserved baseline renal function. Methods: The data of 2,162 adult patients who underwent cardiac surgery from January 2005 to December 2020 were analyzed. Logistic regression models were used to determine predictors of CSA-AKI and their associations with hospital mortality up to 30 days. Results: The prevalence of acute kidney injury was 43.0%, and 2.0% of patients required renal replacement therapy. Hospital mortality rate was 5.6% (non-acute kidney injury = 2.0% vs. CSA-AKI = 10.4%, P<0.001), and any degree of CSA-AKI was associated with a significant increase in death rates (stage 1 = 4.3%, stage 2 = 23.9%, stage 3 = 59.7%). Multivariable logistic regression analysis identified age, obesity, left ventricular dysfunction, previous cardiac surgery, and cardiopulmonary bypass duration as predictors of CSA-AKI. Moreover, CSA-AKI was confirmed as independent predictor of hospital mortality for stage 1 (odds ratio, 2.02; 95% confidence interval, 1.16 to 3.51; P=0.013), stage 2 (odds ratio, 9.18; 95% confidence interval, 4.54 to 18.58; P<0.001), and stage 3 (odds ratio, 37.72; 95% confidence interval, 18.87 to 75.40; P<0.001) patients. Conclusion: Age, obesity, left ventricular dysfunction, previous cardiac surgery, and cardiopulmonary bypass duration are independent predictors of CSA-AKI in patients with preserved baseline renal function. The development of CSA-AKI is significantly associated with worse outcomes, and there is a dose-response relationship between acute kidney injury stages and hospital mortality.

OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.

Introdução: Creatinina sérica (CSr) elevada no período pré-operatório é considerada um fator de risco independente para morbidade e mortalidade em cirurgia cardíaca. Avaliar o impacto da lesão renal aguda pelos critérios Kidney Disease Improving Global Outcomes como preditor de mortalidade em 30 dias em pacientes submetidos à revascularização miocárdica ou cirurgia valvar com creatinina sérica pré-operatória elevada. Métodos: Este foi um estudo retrospectivo de centro único que incluiu pacientes da Unidade de Cuidados Intensivos em Pós-operatório de Cirurgia Cardíaca do Hospital de Base, Faculdade de Medicina de São José do Rio Preto. Dados demográficos, tipos de cirurgia, dados laboratoriais e informações pré, peri e pós-operatórias foram obtidos a partir de uma coleta prospectiva de banco de dados. Foram considerados 2878 pacientes consecutivamente submetidos à revascularização miocárdica ou cirurgia valvar no período de janeiro de 2003 a junho de 2013. Destes, 918 indivíduos apresentavam creatinina sérica alterada no pré-operatório (CrS > 1.30 mg/dL para homens e > 1.00 mg/dL para mulheres), compreendendo 549 pacientes (60%) submetidos à revascularização miocárdica e 369 pacientes (40%) submetidos à cirurgia valvar. O modelo de riscos proporcionais de Cox foi utilizado para avaliar a relação entre lesão renal aguda e mortalidade em 30 dias. Resultados: Nesta casuística, 391 pacientes (43%) apresentaram lesão renal aguda no pós-operatório, sendo 318 (35%) Kidney Disease Improving Global Outcomes estágio 1, 27 (2,9%) Kidney Disease Improving Global Outcomes estágio 2 e 46 (5,0%) Kidney Disease Improving Global Outcomes estágio 3. EuroSCORE, mortalidade em 30 dias, tempo de circulação extracorpórea e permanência em ambiente de terapia intensiva aumentaram progressivamente em todos os estágios. Dentre os pacientes classificados como Kidney Disease Improving Global Outcomes 3, 76% necessitaram diálise com mortalidade em 30 dias de 66%. A análise de Cox evidenciou razão de risco para óbito em 30 dias de 4,8 para pacientes Kidney Disease Improving Global Outcomes estágio 1, 13,5 para pacientes Kidney Disease Improving Global Outcomes estágio 2 e 20,8 para pacientes com Kidney Disease Improving Global Outcomes estágio 3 (P<0,001 para todos). Análise dos subgrupos (revascularização miocárdica e cirurgia valvar) obteve resultados semelhantes. Conclusão: Lesão renal aguda pelos critérios Kidney Disease Improving Global Outcomes destaca-se como excelente preditor de óbito em 30 dias em indivíduos submetidos à revascularização miocárdica ou cirurgia valvar que apresentam creatinina sérica pré-operatória alterada.

Introduction: Preoperatively elevated serum creatinine (SCr) is considered an independent risk factor for morbidity and mortality after cardiac surgery. The aim of this study was to apply the Kidney Disease Improving Global Outcomes classification for acute kidney injury in a population of patients with preoperatively elevated serum creatinine who underwent cardiac surgery (coronary artery bypass grafting or cardiac valve surgery) and to evaluate the acute worsening of renal function as a predictor of 30-day mortality. Methods: This was a single-center retrospective study that included patients from the Postoperative Cardiac Surgery Intensive Care Unit of the Hospital de Base, São José do Rio Preto Medical School. Demographics, type of surgery, laboratory data and pre, peri and postoperative data were obtained from a prospectively collected database. From January 2003 to June 2013, 2,878 patients underwent cardiac surgery, either coronary artery bypass grafting or cardiac valve surgery, at the Hospital de Base of São José do Rio Preto Medical School. Out of those, 918 showed elevated preoperative serum creatinine, with SCr > 1.30 mg/dL for men and > 1.00 mg/dL for women. Five hundred and forty nine patients (60%) undergoing coronary artery bypass grafting and 369 patients (40%) undergoing cardiac valve surgery. A Multivariate Cox Proportional Hazard Model (stepwise) was used to assess the relationship between AKI and mortality at 30 days. Results: Out of the 918 patients studied, 391 (43%) had postoperative AKI: 318 (35%) had Kidney Disease Improving Global Outcomes stage 1, 27 (2.9%) had Kidney Disease Improving Global Outcomes stage 2, and 46 (5.0%) had Kidney Disease Improving Global Outcomes stage 3. Patients in every stage of acute kidney injury showed progressive increase in EuroSCORE values, 30-day mortality ratescardiopulmonary bypass duration, and intensive care length of stay. Among patients classified as Kidney Disease Improving Global Outcomes stage 3, 76% required dialysis with a 30-day mortality of 66%. The Cox proportional hazards model showed that the hazard ratio for 30-day mortality was 4.8 for Kidney Disease Improving Global Outcomes stage 1 patients, 13.5 for Kidney Disease Improving Global Outcomes stage 2 patients, and 20.8 for Kidney Disease Improving Global Outcomes stage 3 patients (P<0.001 for all). Subgroup analyses (coronary artery bypass grafting and cardiac valve surgery) had similar results. Conclusion: In this population, acute kidney injury based on the Kidney Disease Improving Global Outcomes criteria was a powerful predictor of 30-day mortality in patients with elevated preoperative serum creatinine who underwent cardiac surgery (coronary artery bypass grafting or cardiac valve surgery).

OBJETIVO: Avaliamos pacientes submetidos à cirurgia valvar em vigência de endocardite infecciosa na tentativa de identificar preditores independentes de mortalidade intrahospitalar em 30 dias. MÉTODOS: Foram avaliados 837 pacientes consecutivamente submetidos à cirurgia valvar, no período de janeiro de 2003 a maio de 2010, em um hospital terciário de São José do Rio Preto, SP, Brasil. O Grupo de Estudo compreendeu indivíduos submetidos à intervenção em vigência de endocardite infecciosa e foi comparado ao Grupo Controle, considerando complicações clínicas perioperatórias e óbito por todas as causas em 30 dias. RESULTADOS: Em nossa casuística, 64 (8%) pacientes foram submetidos à cirurgia valvar em vigência de endocardite infecciosa, sendo 37,5% deles com indicação de intervenção cirúrgica em múltiplas valvas. O Grupo de Estudo apresentou maior permanência em Unidade de Terapia Intensiva (16%), necessidade de diálise (9%) e maior mortalidade em 30 dias (17%) comparado ao Grupo Controle (7%, P=0,020; 2%, P=0,002 e 9%, P=0,038; respectivamente). A análise de regressão de Cox confirmou idade (P=0,007), lesão renal aguda (P=0,004), diálise (P=0,026), reoperação (P=0,026), reintervenção por sangramento (P=0,013), reintubação orotraqueal (P<0,001) e lesão neurológica tipo I (P<0,001) como preditores independentes para óbito. Embora a manifestação de endocardite infecciosa influencie na mortalidade na análise univariada, a regressão de Cox não confirmou tal variável como preditor independente de óbito em nossa casuística. CONCLUSÃO: Idade e complicações perioperatórias destacam-se como preditores de mortalidade hospitalar em população brasileira. Cirurgia valvar em vigência de infecção ativa não se confirma como preditor independente de óbito nesta casuística.

OBJECTIVE: We evaluated patients underwent cardiac valve surgery in the presence of infective endocarditis in an attempt to identify independent predictors of 30-day mortality. METHODS: We evaluated 837 consecutive patients underwent cardiac valve surgery from January 2003 to May 2010 in a tertiary hospital in São José do Rio Preto, São Paulo (SP), Brazil. The study group comprised patients who underwent intervention in the presence of infective endocarditis and was compared to the control group (without infective endocarditis), evaluating perioperative clinical outcomes and 30-day all cause mortality. RESULTS: In our series, 64 patients (8%) underwent cardiac valve surgery in the presence of infective endocarditis, and 37.5% of them had surgical intervention in multiple valves. The study group had prolonged ICU length of stay (16%), greater need for dialysis (9%) and higher 30-day mortality (17%) compared to the control group (7%, P=0.020; 2%, P=0.002 and 9%, P=0.038; respectively). In a Cox regression analysis, age (P = 0.007), acute kidney injury (P = 0.004), dialysis (P = 0.026), redo surgery (P = 0.026), re-exploration for bleeding (P = 0.013), tracheal reintubation (P <0.001) and type I neurological injury (P <0.001) were identified as independent predictors for death. Although the manifestation of infective endocarditis influenced on mortality in univariate analysis, multivariate Cox regression analysis did not confirm such variable as an independent predictor of death. CONCLUSION: Age and perioperative complications stand out as predictors of hospital mortality in Brazilian population. Cardiac valve surgery in the presence of active infective endocarditis was not confirmed itself as an independent predictor of 30-day mortality.

OBJETIVO: Comparar o desmame da ventilação mecânica realizado segundo a aplicação de protocolo baseado no teste de respiração espontânea e o mesmo procedimento realizado sem padronização, em pacientes cardiopatas. MÉTODOS: Estudo prospectivo, aberto e randomizado. Em 2006, 36 pacientes em ventilação mecânica há mais de 24 horas foram randomizados em dois grupos: grupo controle: 18 pacientes foram submetidos ao desmame da ventilação mecânica de acordo com os procedimentos adotados pela equipe multiprofissional e grupo experimental: 18 pacientes foram submetidos ao desmame de acordo com protocolo previamente estabelecido. RESULTADOS: Os pacientes do grupo controle iniciaram o desmame precocemente em relação ao grupo experimental (74,7 ± 14,7 horas vs. 185,7 ± 22,9 horas; P=0,0004), Porém, após os pacientes do grupo experimental estarem aptos ao desmame, este foi realizado em um tempo mais curto em relação ao grupo controle (149,1 ± 3,6 min vs. 4179,1 ± 927,8 min; P < 0,0001) com taxas de reintubação significativamente menores (16,7% vs. 66,7%; P = 0,005). CONCLUSÃO: O uso de um protocolo específico, baseado no Teste de Respiração Espontânea para desmame de ventilação mecânica, em pacientes cardiopatas, teve resultados melhores do que o desmame realizado sem um protocolo padronizado, com menor tempo de desmame e menores taxas de reintubação.

OBJECTIVE: To compare mechanical ventilation weaning based on a protocol using the spontaneous breathing trial against mechanical ventilation weaning without a standardized protocol in heart patients. METHODS: Prospective, open, randomized study. In 2006, 36 patients undergoing mechanical ventilation for over 24 hours were randomized into two groups: control group - eighteen patients whose mechanical ventilation weaning was performed according to the different procedures adopted by the multidisciplinary team; and experimental group - eighteen patients weaned according to previously established protocol. RESULTS: Control group patients started the weaning process sooner than experimental group patients (74.7 ± 14.7 hours vs. 185.7 ± 22.9 hours, P=0.0004). However, after the experimental group patients were ready for weaning, the extubation was carried out more rapidly than in the control group (149.1 ± 3.6 min vs. 4179.1 ± 927.8 min, P < 0.0001) with significantly lower reintubation rates (16.7% vs. 66.7%, P = 0.005). CONCLUSION: The use of a specific protocol based on the spontaneous breathing trial for mechanical ventilation weaning in heart patients had better outcomes than weaning carried out without a standardized protocol, with shorter weaning times and lower reintubation rates.

OBJETIVO: É comum a obtenção de acesso venoso femoral em pacientes submetidos a cirurgia cardíaca em associação ou como alternativa ao acesso superior (veia jugular interna ou veia subclávia). O objetivo deste estudo foi comparar as medidas de pressão venosa central (PVC) em dois sítios diferentes (superior vs. femoral). MÉTODOS: Estudo prospectivo e aberto com 60 pacientes submetidos a cirurgia cardíaca no período de julho a novembro de 2006. Foram obtidas três medidas de cada paciente em cada sítio (admissão, 6 e 12 horas após a cirurgia) em duas inclinações diferentes da cabeceira do leito (zero e 30 graus), totalizando 720 medidas. RESULTADOS: Cinqüenta e cinco por cento dos pacientes foram submetidos a revascularização do miocárdio, 38% a cirurgia valvar e 7% a outras cirurgias. A média de PVC ± desvio padrão (DP) medida no acesso superior foi de 13,0 ± 5,5 mmHg (zero grau) e 13,3 ± 6,1 mmHg (30 graus), enquanto que as medidas no acesso inferior foram 11,1 ± 4,9 mmHg (zero grau) e 13,7 ± 4,6 mmHg (30 graus). A correlação linear (r) entre as medidas nos dois sítios foi de 0,66 (zero grau) e 0,53 (30 graus), ambas com p < 0,0001. CONCLUSÃO: A PVC pode ser medida com acurácia no acesso venoso femoral no pós-operatório imediato de cirurgia cardíaca, com melhor correlação linear obtida com as medidas feitas com a cabeceira do leito posicionada em zero grau.

OBJECTIVE: It is common to obtain femoral venous approach in patients undergoing combined heart surgery or as an alternative to superior approach (internal jugular vein or subclavian vein). The aim of this study was to compare the measures of central venous pressure (CVP) at two different sites (superior versus femoral). METHODS: We prospectively and openly allocated 60 patients who underwent heart surgery between July from November 2006. Three measures were obtained from each patient at each site (admission, 6 and 12 hours after surgery) in two different inclinations of the headboard (zero and 30 degrees) totaling 720 measures. RESULTS: Fifty five percent of patients who underwent coronary artery bypass grafting, 38% heart valve surgery and 7% other surgeries. The mean of CVP ± standard deviation (SD) measured in superior approach was 13.0 ± 5.5 mmHg (zero degree) and 13.3 ± 6.1 mmHg (30 degrees) while the measures in inferior approach were 11.1 ± 4.9 mmHg (zero degree) and 13.7 ± 4.6 mmHg (30 degrees). The linear correlation (r) between the measures in both sites was 0.66 (zero degree) and 0.53 (30 degrees), both with p value<0.0001. CONCLUSION: The CVP can be measured with accuracy in the femoral venous approach in the immediate postoperative period of heart surgery with better linear correlation obtained with the measures made with the headboard positioned at zero degree.

A sífilis é uma doença infecciosa que se desenvolve em estágios e pode acometer o sistema cardiovascular e neurológico. Em 30% dos pacientes não tratados, a sífilis desenvolve sua forma terciária. Relatamos o caso de um homem de 46 anos, admitido por edema pulmonar agudo por cardiopatia isquêmica com bloqueio completo do ramo esquerdo, submetido a terapia fibrinolítica com sucesso. Angiografia coronária mostrou lesão ostial de 90% na artéria coronária esquerda e oclusão do óstio da artéria coronária direita. Os títulos de VDRL foram de 1/128. O paciente foi submetido a revascularização do miocárdio e recebeu alta após tratamento antibiótico com penicilina cristalina.

Syphilis is an infectious disease occurring through a series of frequently overlapping stages. It can impair the cardiovascular and neurological system. In 30% of the non treated patients, syphilis develops your tertiary form. We report a case of a 46-year-old male patient admitted due to edema pulmonary and acute coronary syndrome with left bundle branch block, submitted to fibrinolytic therapy successfully. Coronary angiography showed a 90% ostial lesion of left main coronary artery and occlusion of the right coronary artery ostium. VDRL was titrated to 1/128. The patient was undergone to CABG and was discharged after treatment with crystalline penicillin.

OBJETIVO: Avaliar o tempo para a estabilização da placa aterosclerótica nas síndromes coronarianas agudas (SCA) utilizando-se marcadores inflamatórios. MÉTODOS: Estudo prospectivo, quarenta pacientes com SCA sem supradesnivelamento de ST versus quarenta indivíduos sem doença coronariana. Proteína C-reativa (PCR), fibrinogênio, fator VIIIc, interleucina-6 e TNF (fator de necrose tumoral)-alfa foram coletados na internação, na alta hospitalar e após três e seis meses. RESULTADOS: Comparada ao controle, a PCR foi significativamente maior na internação e na alta, mas não após três e seis meses. Os níveis de fibrinogênio não apresentaram variações, exceto aos seis meses, quando foi significativamente menor que o controle. O fator VIIIc não diferiu do controle na internação, mas foi significativamente maior na alta, e sem diferenças aos três e seis meses. A IL-6 foi significativamente maior que o controle em todos os períodos. Entretanto, houve queda significativa dos seus níveis entre a alta e três meses. O TNF-alfa não foi significativamente diferente do controle em nenhum momento. Somente a IL-6 se correlacionou significativa e independentemente com eventos cardiovasculares futuros. CONCLUSÃO: Quanto a PCR e fator VIIIc, sugere-se estabilização da placa em até três meses; a análise da IL-6 sugere estabilização a partir do terceiro mês, apesar de permanecer elevada em relação ao controle em até seis meses. Apenas a IL-6 mostrou valor prognóstico de eventos futuros em um ano.

OBJECTIVE: To evaluate the length of time required for atherosclerotic plaque stabilization in acute coronary syndromes (ACS), using inflammatory markers. METHODS: In this prospective study, C-reactive protein (CRP), fibrinogen, factor VIIIc, interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) levels were measured on admission, at discharge, and three and six months post-discharge in 40 patients with non-ST-segment elevation ACS (NSTE-ACS) and 40 healthy subjects. RESULTS: C-reactive protein levels were significantly higher on admission and at discharge, but not at three and six months post-discharge, compared with the control group. Fibrinogen levels remained unchanged, except at six months, when they were significantly lower than in the control group. Factor VIII-c did not differ from that of the control group on admission, but it was significantly higher at discharge, with no differences at three and six months. Interleukin-6 levels were significantly higher than in the control group in all time points. However, they declined significantly between discharge and three months. In no time point was TNF-alpha significantly different from that of the control group. Only IL-6 correlated significantly and independently with future cardiovascular events. CONCLUSION: With respect to CRP and factor VIIIc, plaque stabilization is suggested in up to three months; IL-6 analysis suggests stabilization as from the third month, although it remained higher than that of the control group for up to six months. Only IL-6 showed prognostic value for further events within a year.

A avaliação e estratificação de pacientes com dor torácica na sala de emergência pode nos direcionar a terapêutica adequada a cada paciente baseada na probabilidade da presença de doença coronariana aguda e no risco de eventos cardíacos maiores desta coronariopatia. Esta avaliação é baseada no tripé: quadro clínico, achados eletrocardiográficos e nos marcadores de lesão miocárdica. Relatamos o caso de um paciente chagásico de 58 anos de idade admitido na unidade de emergência por dor torácica e palpitações, com eletrocardiograma mostrando uma taquicardia ventricular sustentada e com dosagem de troponina positiva (0,99 ng/ml), submetido a cinecoronariografia, que não evidenciou doença coronariana obstrutiva.

The assessment and stratification of patients with chest pain in the emergency unit may indicate the appropriate therapy for each patient based on the probability of the presence of acute coronary artery disease and on the risk of its major cardiac events. That assessment is based on the triplet: clinical setting, electrocardiographic findings, and markers of myocardial lesion. We report the case of a 58-year-old male chagasic patient admitted to the emergency unit due to chest pain and palpitations, with an electrocardiogram showing sustained ventricular tachycardia and positive troponin measurement (0.99 ng/mL). The patient underwent cine coronary angiography, which evidenced no obstructive coronary artery disease.

OBJETIVO: Estudo multicêntrico, aberto e não comparativo, para avaliar a eficácia e a tolerabilidade de dois agentes anti-hipertensivos combinados em doses baixas: o beta-bloqueador cardiosseletivo bisoprolol (2,5 e 5,0mg) com 6,25mg de hidroclorotiazida. MÉTODOS: Cento e seis pacientes com hipertensão arterial nos estágios I e II (leve a moderada) receberam a combinação bisoprolol/hidroclorotiazida, em uma única dose diária, e foram submetidos a uma avaliação da pressão arterial sistólica (PAS) e pressão arterial diastólica (PAD), durante 8 semanas. RESULTADOS: A combinação bisoprolol/hidroclorotiazida reduziu significativamente os valores médios iniciais da PAS (157,4mmHg para 137,3mmHg) e da PAD (98,8mmHg para 87,4mmHg). Ao final do estudo, 61% haviam normalizado a PA (<90mmHg) e 22,9% deles foram responsivos ao tratamento, resultando em elevada taxa de resposta terapêutica (normalizados + responsivos) - total de 83.9% dos casos. Eventos adversos foram descritos em 18,9% dos pacientes, sendo os mais freqüentes: tontura e cefaléia. Não se observaram alterações clinicamente significativas nos níveis plasmáticos de glicose, potássio, ácido úrico e perfil lipídico. CONCLUSÃO: A combinação bisoprolol/hidroclorotiazida em baixas doses pode ser considerada uma alternativa racional, eficaz e bem tolerada para o tratamento inicial da hipertensão arterial leve ou moderada.

PURPOSE: Multicenter, open and non-controlled study to evaluated the efficacy and the tolerability of a low-dose combination of two anti-hypertensive agents: a cardioselective beta-blocker, bisoprolol (2.5 and 5.0mg) with 6.25mg of hydrochlorothiazide. METHODS: One hundred and six patients in the stage I and stage II of the systemic hypertension (mild to moderate) were given the bisoprolol/hydrochlorothiazide combination once daily and the diastolic and systolic blood pressures were monitored during the 8-week trial. RESULTS: The bisoprolol/hydrochlorothiazide combination reduced the initial mean values of systolic and diastolic blood pressures, respectively, from the 157.4mmHg and 98.8mmHg to 137.3mmHg and 87.4mmHg. At the end of the treatment period, 61% of the patients normalized blood pressure values (<90mmHg) and 22.9% of them had responded to the treatment, resulting in a total response rate (normalized + responsive) of 83.9% of cases. Adverse events were described only in 18.9% of the patients and dizziness and headache were the most common. There were no clinically significant changes on plasma levels of potassium, uric acid, glucose, or in the lipid profile. CONCLUSION: The combination of low dosages of bisoprolol and hydrochlorothiazide may be considered an effective, well tolerated and rational alternative for the initial treatment of the patients with mild to moderate hypertension.
