ABSTRACT

CONTEXT AND OBJECTIVES: Glycoprotein inhibitors (abciximab, eptifibatide and tirofiban) are used in patients with unstable angina and non-ST-segment elevation myocardial infarction before percutaneous coronary intervention. Of these, tirofiban is the least effective. We hypothesized that the response to tirofiban might be associated with glycoprotein gene mutations. DESIGN AND SETTING: Prospective study at Emergency Unit, Heart Institute (InCor), University of São Paulo. METHOD: Intrahospital evolution and platelet aggregation in response to tirofiban were analyzed in relation to four glycoprotein mutations in 50 patients indicated for percutaneous coronary intervention: 17 (34%) with unstable angina and 33 (66%) with non-ST-segment elevation myocardial infarction. Platelet aggregation was analyzed using the Born method. Blood samples were obtained before and one hour after tirofiban infusion. Glycoproteins Ia (807C/T ), Ib (Thr/Met) , IIb (Ile/Ser ) and IIIa (PIA ) were the mutations selected. RESULTS: Hypertension, dyslipidemia, diabetes, smoking, previous coronary artery disease and stroke were similar between the groups. Mutant glycoprotein IIIa genotypes had lower platelet aggregation before tirofiban administration than that of the wild genotype (41.0% ± 22.1% versus 55.9% ± 20.8%; P = 0.035). Mutant glycoprotein IIIa genotypes correlated moderately with lower platelet inhibition (r = -0.31; P = 0.030). After tirofiban administration, platelet glycoprotein Ia, Ib, IIb and IIIa mutations did not influence the degree of inhibition of platelet aggregation or intrahospital mortality. CONCLUSIONS: Mutations of glycoproteins Ia, Ib, IIb and IIIa did not influence platelet aggregation in response to tirofiban in patients with unstable angina and non-ST-segment elevation myocardial infarction.


RESUMO CONTEXTO E OBJETIVOS: Inibidores da glicoproteína (abciximab, eptifibatide, tirofiban) são utilizados em pacientes com angina instável e infarto do miocárdio sem elevação do segmento ST (IAMSSST) antes da intervenção coronária percutânea. Dentre eles, o tirofiban é o menos eficaz. Nossa hipótese é que a resposta ao tirofiban possa estar associada a mutações no gene da glicoproteína. DESENHO E LOCAL: Estudo prospectivo na Unidade de Emergência do Instituto do Coração (InCor), Universidade de São Paulo (USP). MÉTODOS: Foram analisadas a evolução intra-hospitalar e agregabilidade plaquetária em resposta ao tirofiban de 4 mutações da glicoproteína em 50 pacientes com indicação para intervenção coronária percutânea, 17 (34%) com angina instável e 33 (66%) com IAMSSST. A agregação plaquetária foi analisada pelo método de Born. Amostras de sangue foram obtidas antes e uma hora após infusão do tirofiban. As glicoproteínas Ia (807C/T ), Ib (Thr/Met ), IIb (Ile/Ser ) e IIIa (PIA ) foram as mutações selecionadas. RESULTADOS: Hipertensão, dislipidemia, diabetes, tabagismo, doença coronariana e acidente vascular cerebral prévios foram semelhantes entre os grupos. Observou-se menor agregabilidade plaquetária dos genótipos mutantes da glicoproteína IIIa antes da administração de tirofiban do genótipo selvagem (41% ± 22% versus 56% ± 21%; P = 0,035). Genótipos mutantes da glicoproteína IIIa correlacionaram-se moderadamente com menor inibição plaquetária (r = -0,31; P = 0,030). Após a administração tirofiban, as mutações das glicoproteínas Ia, Ib, IIb, e IIIa não influenciaram o grau de inibição da agregação plaquetária e mortalidade intra-hospitalar. CONCLUSÕES: Mutações das glicoproteínas Ia, Ib, IIb e IIIa não influenciaram a agregação plaquetária em resposta ao tirofiban nos pacientes com angina instável e IAMSSST.

ABSTRACT

Abstract Background: Truck driver sleepiness is a primary cause of vehicle accidents. Several causes are associated with sleepiness in truck drivers. Obesity and metabolic syndrome (MetS) are associated with sleep disorders and with primary risk factors for cardiovascular diseases (CVD). We analyzed the relationship between these conditions and prevalence of sleepiness in truck drivers. Methods: We analyzed the major risk factors for CVD, anthropometric data and sleep disorders in 2228 male truck drivers from 148 road stops made by the Federal Highway Police from 2006 to 2011. Alcohol consumption, illicit drugs and overtime working hours were also analyzed. Sleepiness was assessed using the Epworth Sleepiness Scale. Results: Mean age was 43.1 ± 10.8 years. From 2006 to 2011, an increase in neck (p = 0.011) and abdominal circumference (p < 0.001), total cholesterol (p < 0.001), triglyceride plasma levels (p = 0.014), and sleepiness was observed (p < 0.001). In addition, a reduction in hypertension (39.6% to 25.9%, p < 0.001), alcohol consumption (32% to 23%, p = 0.033) and overtime hours (52.2% to 42.8%, p < 0.001) was found. Linear regression analysis showed that sleepiness correlated closely with body mass index (β = 0.19, Raj2 = 0.659, p = 0.031), abdominal circumference (β = 0.24, Raj2 = 0.826, p = 0.021), hypertension (β = -0.62, Raj2 = 0.901, p = 0.002), and triglycerides (β = 0.34, Raj2 = 0.936, p = 0.022). Linear multiple regression indicated that hypertension (p = 0.008) and abdominal circumference (p = 0.025) are independent variables for sleepiness. Conclusions: Increased prevalence of sleepiness was associated with major components of the MetS.


Resumo Fundamento: A sonolência de motoristas de caminhão, que pode resultar de diferentes causas, é a principal causa de acidentes com veículos. Obesidade e síndrome metabólica (SMet) estão associadas a distúrbios do sono e fatores de risco primários para doença cardiovascular (DCV). Este estudo verificou a relação entre essas condições e a prevalência de sonolência em motoristas de caminhão. Métodos: Este estudo analisou os principais fatores de risco para DCV, dados antropométricos e distúrbios do sono em 2.228 motoristas de caminhão do sexo masculino a partir de informação coletada de 148 paradas efetuadas em rodovias pela Polícia Rodoviária Federal entre 2006 e 2011. Consumo de álcool e de drogas ilícitas e excesso de horas trabalhadas também foram analisados. Sonolência foi avaliada com a Escala de Sonolência de Epworth. Resultados: A idade média foi de 43,1 ± 10,8 anos. De 2006 a 2011, observou-se aumento de: circunferências cervical (p = 0,011) e abdominal (p < 0,001); colesterol total (p < 0,001); níveis séricos de triglicerídeos (p = 0,014); sonolência (p < 0,001). Além disso, houve redução de hipertensão (de 39,6% para 25,9%, p < 0,001), consumo de álcool (de 32% para 23%, p = 0,033) e excesso de horas trabalhadas (de 52,2% para 42,8%, p < 0,001). A análise de regressão linear mostrou correlação íntima de sonolência com índice de massa corporal (β = 0,19, Raj2 = 0,659, p = 0,031), circunferência abdominal (β = 0,24, Raj2 = 0,826, p = 0,021), hipertensão (β = -0,62, Raj2 = 0,901, p = 0,002) e triglicerídeos (β = 0,34, Raj2 = 0,936, p = 0,022). Regressão linear múltipla indicou que hipertensão (p = 0,008) e circunferência abdominal (p = 0,025) são variáveis independentes para sonolência. Conclusões: Elevada prevalência de sonolência foi associada com os principais componentes da SMet.

ABSTRACT

FUNDAMENTO: Há controvérsias sobre a hora da admissão e os desfechos hospitalares da síndrome coronária aguda (SCA). A admissão em horários não regulares seria associada ao pior prognóstico dos pacientes. OBJETIVO: Analisar a influência da hora da admissão na internação prolongada e na mortalidade de pacientes com SCA, segundo os períodos diurno (das 7h às 19h) e noturno (das 19h às 7h). MÉTODOS: Foram avaliados, prospectivamente, 1.104 pacientes consecutivos com SCA. O óbito intra-hospitalar e a internação igual ou superior a cinco dias foram os desfechos analisados. RESULTADOS: A admissão no período diurno foi maior em comparação ao noturno (63 por cento vs. 37 por cento; p < 0,001). A angina instável foi mais prevalente no período diurno (43 por cento vs. 32 por cento; p < 0,001) e o infarto sem supradesnivelamento do segmento ST (IAMssST) no noturno (33 por cento vs. 43 por cento; p = 0,001). Não se observaram diferenças na mortalidade e no tempo de internação nos períodos estudados. Os fatores de predição de internação igual ou superior a cinco dias foram: idade [OR 1,042 (IC 95 por cento 1,025 - 1,058), p < 0,001]; fração de ejeção (FE) [OR 0,977 (IC 95 por cento 0,966 - 0,988), p < 0,001]; IAMssST [OR 1,699 (IC 95 por cento 1,221 - 2,366), p = 0,001]; e tabagismo [OR 1,723 (IC 95 por cento 1,113 - 2,668), p = 0,014]. Para o óbito intra-hospitalar, foram: idade [OR 1,090 (IC 95 por cento 1,047 - 1,134), p < 0,001]; FE [OR 0,936 (IC 95 por cento 0,909 - 0,964), p < 0,001]; e tratamento cirúrgico [OR 3,781 (IC 95 por cento 1,374 - 10,409), p = 0,01]. CONCLUSÃO: A internação prolongada e óbito intra-hospitalar em pacientes com SCA independem do horário de admissão.


BACKGROUND: The relationship between admission time to an emergency service and in-hospital outcomes in acute coronary syndrome (ACS) is controversial. Admission during off-hours would be associated with worse prognosis. OBJECTIVE: To assess the influence of admission time on prolonged hospitalization and mortality for ACS patients, regarding regular hours (7AM-7PM) and off-hours (7PM-7AM). METHODS: The study assessed prospectively 1,104 consecutive ACS patients. In-hospital mortality and length of hospital stay > 5 days were the outcomes analyzed. RESULTS: Admission during regular hours was greater as compared with that during off-hours (63 percent vs. 37 percent; p < 0.001). Unstable angina was more prevalent during regular hours (43 percent vs. 32 percent; p < 0.001), while non-ST-segment elevation myocardial infarction (NSTEMI) was during off-hours (33 percent vs. 43 percent; p = 0.001). Differences in neither mortality nor length of hospital stay were observed in the time periods studied. Predictive factors for length of hospital stay > 5 days were as follows: age [OR 1.042 (95 percentCI: 1.025 - 1.058), p < 0.001]; ejection fraction (EF) [OR 0.977 (95 percentCI: 0.966 - 0.988), p < 0.001]; NSTEMI [OR 1.699 (95 percentCI: 1.221 - 2.366), p = 0.001]; and smoking [OR 1.723 (95 percentCI: 1.113 - 2.668), p = 0.014]. Predictive factors for in-hospital mortality were as follows: age [OR 1.090 (95 percentCI: 1.047 - 1.134), p < 0.001]; EF [OR 0.936 (95 percentCI: 0.909 - 0.964), p < 0.001]; and surgical treatment [OR 3.781 (95 percentCI: 1.374 - 10.409), p = 0.01]. CONCLUSION: Prolonged length of hospital stay and in-hospital mortality in ACS patients do not depend on admission time.

ABSTRACT

OBJECTIVE: Anticoagulation is a challenge for the prophylaxis of thromboembolic events in elderly patients with chronic atrial fibrillation. Stable anticoagulation is defined as the time within >70% of the therapeutic range. However, the dosage required to achieve stable anticoagulation remains unknown. The aim of this study was to analyze the warfarin dose necessary for the maintenance of stable oral anticoagulation therapy in elderly patients. METHODS: We analyzed 112 consecutive outpatients with atrial fibrillation who were >65 years of age, had received anticoagulation therapy with warfarin for more than 1 year and had a stable international normalized ratio between 2.0 and 3.0 for >6 months. The international normalized ratio was measured in the central laboratory using the traditional method. RESULTS: The patients were stratified according to the following age groups: <75 or >75 years and <80 or >80 years. The mean daily doses of warfarin were similar for patients <75 or >75 years (3.34+1.71 versus 3.26 +1.27 mg/ day, p = 0.794) and <80 or >80 years (3.36+ 1.49 versus 3.15 + 1.23 mg/day, p = 0.433). In 88 (79%) patients, the daily warfarin dose was between 2 and 5 mg/day; in 13 (11%) patients, the daily warfarin dose was <2.0 mg/day; and in 11 (10%) patients, the daily warfarin dose was >5.0 mg/day. The correlation between the daily warfarin dose and the international normalized ratio was 0.22 (p = 0.012). CONCLUSION: Stable anticoagulation was achieved in 80% of patients who received doses of 2 to 5 mg/day of warfarin, and the mean daily dose was similar across the age groups analyzed.

ABSTRACT

OBJECTIVE: Involvement of the left ventricular anterior wall in ST-elevation myocardial infarction has a worse prognosis compared with other regions. In non-ST-elevation myocardial infarction, noninvasive methods of locating the ischemic myocardial territory have been limited. The objective of this report is therefore to determine what factors are predictive of the anterior location of the ischemic myocardial territory. METHODS: This study included 170 patients with non-ST-elevation myocardial infarction. Clinical, echocardiographic, and laboratory characteristics, including B-type natriuretic peptide measured within 24 hours of hospitalization, and coronary angiographic features were analyzed. RESULTS: The mean age was 64.5 ± 12.3 years, and 112 of the patients were male (66 percent). The median follow-up was 23 months. The territory involved, as determined from the angiogram, was divided into anterior [n = 80 (47 percent)] regions and inferior and lateral [n = 90 (53 percent)] regions. Multivariate analysis showed that B-type natriuretic peptide was the only independent predictor of an anterior wall infarct [OR = 3.70 (95 percent CI: 1.61 - 8.53); P = 0.002] in non-STelevation myocardial infarction patients. Multivariate analysis also showed that B-type natriuretic peptide was an independent predictor of in-hospital cardiac events during index admission [OR = 5.05 (95 percent CI: 1.49 - 17.12); P = 0.009] and of cardiac events occurring during follow-up [HR = 1.79 (95 percent CI: 1.05 - 3.04); P = 0.032]. CONCLUSIONS: B-type natriuretic peptide was the only factor independently associated with anterior wall involvement in non-ST-elevation myocardial infarction, and the peptide levels upon admission predicted in-hospital and subsequent cardiac events.

ABSTRACT

OBJECTIVE: Cardiovascular diseases are the main cause of death in women and men in Brazil, but the trends for the death ratios for ischemic heart disease and stroke in women and men remain unknown. METHOD: In this study, the trends for the death ratios among women and men who were over 30 years of age were analyzed from 1980 to 2005. Data were collected for both the Brazilian population and the metropolitan area of São Paulo. Estimates of the population size and data for mortality were then obtained from the Brazilian Institute of Geography and Statistics and the Ministry of Health. The risk for death was adjusted using a direct method. RESULTS: Death rates due to cardiovascular disease, ischemic heart disease, and stroke have declined in both Brazil and the metropolitan region of São Paulo. A linear regression analysis revealed a similar trend for ischemic heart disease and demonstrated a male/female ratio of 1.653 ± 0.001 (r=0.228; p=0.262) in Brazil and 1.763 ± 0.008 (r=0.863; p<0.001) in São Paulo. Comparisons between the slopes of the linear regressions showed an increased ischemic heart disease ratio in men/women in São Paulo in comparison to those in Brazil (p<0.0001). The linear regression showed an increasing trend for the male/female stroke ratio of 1.252 ± 0.004 (r=0.776; p<0.0001) in Brazil and 1.331 ± 0.006 (r=0.580; p=0.002) in São Paulo. Comparisons between the regressions for the stroke ratio were similar for men/women in São Paulo compared to Brazil (p=0.244). CONCLUSION: We observed an increased trend in the ratio for ischemic heart disease death in men compared to women. Improvements in the control of risk factors and treatments for both men and women are mandatory to reduce the number of ischemic heart disease-related deaths in Brazil.

ABSTRACT

FUNDAMENTO: As doenças circulatórias (DC) são as principais causas de morte no Brasil, com predomínio das doenças cerebrovasculares (DCbV). Nos países desenvolvidos, predominam as doenças isquêmicas do coração (DIC). OBJETIVO: Analisar a relação entre DCbV/DIC em homens e mulheres a partir de 30 anos. MÉTODOS: As estimativas da população e os dados de mortalidade para DC, DIC e DCbV foram obtidos do Ministério da Saúde para o período entre 1980 e 2005. O risco de morte por DIC e DCbV por 100.000 habitantes e a relação entre DCbV/DIC foram analisados nas faixas etárias decenais a partir de 30 anos. O risco de morte foi ajustado pelo método direto, usando como população padrão a população mundial de 1960. RESULTADOS: Observou-se aumento exponencial do risco de morte por DIC e DCbV, com o aumento da faixa etária. DCbV foi a principal causa de morte no Brasil até 1996, quando passou a predominar a DIC. Foi observada redução de 33,25 por cento no risco de morte por DC na população brasileira. Na região metropolitana de São Paulo, houve uma diminuição de 45,44 por cento, entre 1980 e 2005. A relação DCbV/DIC foi maior nas mulheres mais jovens: de 2,53 em 1980 e 2,04 em 2005 para a população brasileira, e de 2,76 em 1980 e 1,96 em 2005 na região metropolitana de São Paulo, com decréscimo nas faixas etárias subsequentes. Nos homens, a relação DCbV/DIC foi próximo de <1 para todas as faixas etárias. CONCLUSÃO: Observou-se, no Brasil, uma transição do risco de morte por DC, com predomínio atual das DIC.


BACKGROUND: Circulatory diseases (CD) are the major cause of death in Brazil, being cerebrovascular diseases (CVD) predominant. In developed countries ischemic heart diseases (IHD) predominate. OBJECTIVE: The objective of the present study was to investigate the ratio between cerebrovascular diseases/ischemic heart diseases (CVD/IHD) in males and females who were 30 years of age and older. METHODS: Population estimates and mortality data for CD, IHD and CVD were provided by the Ministry of Health for the period between 1980 and 2005. The risk of death from IHD and CVD per 100,000 Brazilians and CVD/IHD ratio were analyzed in 10-year age ranges as of 30 years of age. The risk of death was adjusted by direct method by using 1960 world population as the standard population. RESULTS: It was observed that the risk of death from IHD and CVD increased exponentially as age advanced. CVD was the major cause of death in Brazil until 1996, when IHD took the lead. In the period between 1980 and 2005 a 33.25 percent reduction in death risk from CD was observed in the Brazilian population. In that same period, the metropolitan area of the capital city of São Paulo reported a 45.44 percent reduction. The CVD/IHD ratio was shown to be higher among younger women - from 2.53 in 1980 down to 2.04 in 2005 in the Brazilian population, and from 2.76 in 1980 down to 1.96 in the metropolitan area of the capital city of São Paulo, with decreasing figures for subsequent age ranges. Among males, the CVD/IHD ratio was close to < 1 in all age ranges. CONCLUSION: A transition in death risk from CD could be observed in Brazil, with current predominance of IHD.


FUNDAMENTO: Las enfermedades circulatorias (EC) son las principales causas de muerte en Brasil, con el predominio de las enfermedades cerebrovasculares (ECbV). En los países desarrollados predominan las enfermedades isquémicas del corazón (EIC). OBJETIVO: Analizar la relación entre ECbV/EIC en varones y mujeres a partir de 30 años. MÉTODOS: Se obtuvieron en el Ministério de la Salud las estimaciones de la población y los datos de mortalidad para EC, EIC y ECbV para el periodo entre 1980 y 2005. Se analizaron el riesgo de muerte por EIC y ECbV por 100.000 habitantes y la relación entre ECbV/EIC en los grupos de edad decenales a partir de 30 años. Se ajustó el riesgo de muerte por el método directo, usándose como población estándar la población mundial de 1960. RESULTADOS: Se observó un aumento exponencial del riesgo de muerte por EIC y ECbV, con el aumento del grupo de edad. La ECbV fue la principal causa de muerte en Brasil hasta 1996, cuando pasó a predominar la EIC. Se observó una reducción del 33,25 por ciento en el riesgo de muerte por EC en la población brasileña. En la región metropolitana de São Paulo, hubo una disminución del 45,44 por ciento entre 1980 y 2005. La relación ECbV/EIC fue mayor en las mujeres más jóvenes: del 2,53 por ciento en 1980 y del 2,04 por ciento en 2005 para la población brasileña, y del 2,76 por ciento en 1980 y del 1,96 por ciento en 2005 en la región metropolitana de São Paulo, con reducción en los grupos de edad subsiguientes. En los varones, la relación ECbV/EIC fue cerca de <1 para todas los grupos de edad. CONCLUSIÓN: Se observó en Brasil una transición del riesgo de muerte por EC con predominio actual de las EIC.

ABSTRACT

OBJETIVO: Analisar tendências do risco de morte por doenças circulatórias (DC) em 13 estados do Brasil, no período de 1980 a 1998. MÉTODOS: Dados de mortalidade por DC, isquêmicas do coração (DIC) e cerebrovasculares (DCbV) nos 13 estados foram obtidos do Ministério da Saúde. Estimativas das populações, de 1980 a 1998, foram calculadas por meio de interpolação, pelo método de Lagrange, com base nos dados dos Censos de 1970, 1980, 1991 e contagem populacional de 1996. As tendências foram analisadas pelo modelo de regressão linear múltipla. RESULTADOS: A mortalidade por DC mostrou tendência de queda na maioria dos estados. Observou-se aumento, nos homens, em Pernambuco, para todas as faixas etárias, em Goiás, a partir de quarenta anos e na Bahia e Mato Grosso, a partir dos cinqüenta anos. Nas mulheres, aumento em Mato Grosso, a partir dos trinta anos, em Pernambuco, a partir dos quarenta anos, e em Goiás, nas faixas etárias entre trinta e 49 anos. Em Goiás, nas outras faixas etárias, o aumento foi discreto. Para as DIC, aumento da mortalidade para todas as faixas etárias em Mato Grosso e Pernambuco, e a partir dos quarenta anos, na Bahia, Goiás e Pará. Para as DCbV, aumento da mortalidade para todas as faixas etárias em Mato Grosso e Pernambuco, e a partir dos quarenta anos na Bahia e em Goiás. CONCLUSÃO: Observou-se importante aumento do risco de morte para as doenças circulatórias nos estados menos desenvolvidos do Brasil.


OBJECTIVE: Analyze the trends in the risk of death from circulatory diseases (CD) in thirteen states in Brazil between 1980 and 1998. METHODS: Data on mortality from CD, ischemic heart diseases (IHD), and cerebrovascular diseases (CVD) in thirteen states were obtained from the Ministry of Health data base. Populational estimates from 1980 to 1998 were calculated through interpolation, using the Lagrange method, based on data from the 1970, 1980, 1991 censuses, and 1996 populational count. The trends were analyzed by multiple linear regression model. RESULTS: Mortality due to CD showed a trend towards decrease in most states. In Pernambuco state males presented increase in all age ranges, whereas in Goiás increase was shown from 40 years of age on, and in Bahia and Mato Grosso, from 50 years of age. Females showed increase starting at 30 in Mato Grosso, at 40 in Pernambuco, and in Goiás, in the age ranging from 30 to 49 years of age. In Goiás, increase was discreet in all other age ranges. As for IHD, mortality increase was reported in all age ranges in Mato Grosso and Pernambuco; in Bahia, Goiás and Pará, from 40 on. As for CVD, mortality increase was reported in all age ranges in Mato Grosso and Pernambuco; and from 40 on in Bahia and Goiás. CONCLUSION: Significant increase in the risk of death from circulatory diseases could be observed in less developed states in Brazil.

ABSTRACT

OBJETIVOS: Inflamação e ativação das células do sistema imunológico têm participação importante na patogênese da aterosclerose. Este estudo analisa o leucograma que incluiu neutrófilos, eosinófilos, linfócitos, monócitos e basófilos dos pacientes com doença arterial coronariana (DAC) crônica e no infarto agudo do miocárdio (IAM). MÉTODOS: Analisamos o leucograma de 232 pacientes não-diabéticos, com idade entre 15 e 88 anos. A DAC estava presente em 142 pacientes (57 com DAC estável e 85 com IAM), diagnosticada angiograficamente, comparada a 90 indivíduos-controle. Os grupos controle e DAC foram comparáveis para a idade, índice de massa corpórea, antecedentes familiares, tabagismo, hipertensão, HDL e LDL (todas variáveis com p > 0,25). RESULTADOS: A análise univariada mostrou maior prevalência de leucocitose na DAC, sendo maior nos pacientes com IAM quando comparados com a DAC estável. O mesmo comportamento foi observado para os monócitos. Porém, a distribuição foi semelhante para as demais células do hemograma. A análise multivariada pelo método da regressão logística, utilizando-se os modelos stepwise (todas variáveis) e backward (p < 0,25), mostrou que a monocitose foi variável independente para DAC e para o IAM. CONCLUSÃO: O número de monócitos, um dos mais importantes componentes do processo inflamatório na placa aterosclerótica, foi um marcador de risco independente para a DAC e para o IAM.

ABSTRACT

A evolução da estenose valvar aórtica caracteriza-se por ser um processo lento e gradual, com um longo período de latência no qual o paciente se mantém assintomático, mesmo na presença de lesão valvar acentuada. A partir do momento em que se iniciam os sintomas, é consenso a indicação do tratamento cirúrgico de troca valvar aórtica. Estudo prospectivo realizado no Instituto do Coração (InCor ù HC-FMUSP), com 133 pacientes com estenose aórtica acentuada (gradiente ventrículo esquerdo/aorta > 60 mmHg), demonstrou que a morte súbita foi um evento raro que ocorreu em 5 por cento (n = 7) dos pacientes, em um tempo médio de seguimento de 1,32 + 1,11 ano. Em nosso estudo, a diminuição progressiva da função ventricular esquerda, redução essa dentro de uma faixa de valores normais, foi o único fator de risco independente de predição de eventos. Pacientes assintomáticos com disfunção ventricular esquerda devem ser submetidos a troca valvar, mesmo estando assintomáticos.

ABSTRACT

OBJECTIVE: To analyze the trends in mortality due to circulatory diseases in men and women aged > or = 30 years in Brazil from 1979 to 1996. METHODS: We analyzed population count data obtained from the IBGE Foundation and mortality data obtained from the System of Information on Mortality of the DATASUS of the Ministry of Health. RESULTS: Circulatory diseases, ischemic heart disease, and cerebrovascular disease were the major causes of death in men and women in Brazil. The standardized age coefficient for circulatory disease in men aged > or = 30 years ranged from 620 to 506 deaths/100,000 inhabitants and in women from 483 to 383 deaths/100,000 inhabitants for the years 1979 and 1996, respectively. In men, the mean coefficient for the period was 586.25 deaths with a significant trend towards a decrease (P<0.001) and a decline of 8.25 deaths/year. In women, the mean coefficient for the period was 439.58 deaths, a significant trend towards a decrease (P<0.001) and a rate of decline of 7.53 deaths/year. The same significant trend towards a decrease in death (P<0.001) was observed for ischemic heart disease and cerebrovascular disease. Risk of death from these causes was always higher for men of any age group (P<0.001). Cerebrovascular disease was the primary cause of death in women. CONCLUSION: Although circulatory diseases have been the major cause of mortality in men and women in the Brazilian population, with a greater participation by cerebrovascular diseases, a trend towards a decrease in the risk of death from these causes is being observed

ABSTRACT

Objetivo Avaliar o efeito do diazepam, nifedipina, propranolol e da associação nifedipina e propranolol, por via sublingual, na crise hipertensiva (CH). Métodos Oitenta pacientes em CH, compressão arterial diastólica (PAD) maior de 120mmHg, com idade de 54,0 ± 7,4 anos, sendo 47 homens. A pressão arterial (PA) foi medida com esfigmomanômetro aneróide, em mmHg. com o paciente em posição ortostática, antes do tratamento e 10, 20, 30 e 60 minutos após. A freqüência cardíaca (FC) em um minuto também foi medida nos períodos acima. Os pacientes foram divididos aleatoriamente em 4 grupos e tratados com uma das seguintes alternativas: 110 mg de diazepam; 2 - 10 mg de nifedipina; 340 mg de propranolol e 4 - 10 mg de nidedipina associado a 40 mg de propranolol, todos administra dos por via sublingual. Resultados Observou-se redução significativa e gradativa da pressão arterial sistólica (PAS) e da PAD nos 4 grupos. A porcentagem de redução após 60 minutos, da PAS para os grupos de I a IV foi respectivamente de 10,1%, 12,9%;15,4% e 16%, e para a PAD foi de 7,7%, 11,3%, 13,6% e 13%. A FC manteve-se inalterada nos grupos I e II, com redução significativa nos grupos III (p = 0,002) e IV (p = 0,009)...


Purpose To evaluate the effects of sublingual administration of diazepan, nifedipine, propranolol and the association of nifedipine with propranolol patients with hypertensive crisis. Methods Eighty patients with hypertensive crisis, DAP > 120 mmHg, and mean age of 54 ± 7,4 years, 33 women and 47 men, were evaluated. The AP was measured with an aneroid sphygmomanometer, in mmHg, in orthostatic position, before and after 10, 20, 30 and 60 minutes of treatment. The heart rate in one minute was also measured at the same intervals. The patients were divided randomily into four groups and treated, respectively, with 10 mg of diazepan, 10 mg of nifedipine, 40 mg of propranolol and 10 mg of nifedipine associated with 40 mg of propranolol. Results A significant and gradual reduction of SAP and DAP were observed in all groups of patients. The percentage of reduction, after 60 minutes, for SAP was, respectively, 10.1%, 12.9%.15.4% and 16%, and for DAP 7.7%, 11.3%, 13.6% and 13% in groups I to IV. The heart rate did not change in groups I and II, but significative reduction was observed in groups III (p= 0.002) and IV (p =0.009)...
