RESUMO

The objective of this study was to evaluate the association between frailty, evaluated by the Clinical Frailty Scale (CFS) and FRAIL scale, and C-terminal agrin fragment (CAF) levels with 3-month mortality following ST-segment elevation myocardial infarction (STEMI). This was a prospective observational study that included patients over the age of 18 years with STEMI admitted to the coronary intensive care unit. Within 48 h of admission, the CFS and FRAIL scale were applied and blood samples collected for serum CAF evaluation. Patients were followed for 3 months after hospital discharge, and mortality was recorded. One hundred and eleven patients were included; mean age was 62.3 ±â€¯12.4 years, 61.3% were male and 11.7% died during the 3 months of follow-up. According to the CFS, 79.3% of the patients were classified as not frail, 12.6% as pre-frail and 8.1% as frail. According to the FRAIL scale, 31.5% of the patients were classified as not frail, 53.2% as pre-frail and 15.3% as frail. In univariate analysis, the CFS but not FRAIL scale was associated with mortality. In multiple logistic regression analysis, pre-frail/frail according to CFS (odds ratio [OR]: 6.118; CI 95%: 1.344-27.848; p = 0.019) and CAF levels (OR: 0.943; CI 95%: 0.896-0.992; p = 0.024) were associated with increased 3-month mortality. In a sub-analysis of 53 patients ≥65 years, CFS and CAF levels were associated with 3-month mortality. In conclusion, CAF levels and frailty determined by the CFS were associated with 3-month mortality after STEMI in the general and older population.

RESUMO

OBJECTIVES: Doxorubicin is a highly effective chemotherapeutic agent for treating several types of cancer; however, it can induce cardiotoxicity. We evaluated the influence of Pera and Moro orange juices on cardiac remodeling induced by acute administration of doxorubicin in rats. METHODS: We allocated 120 male Wistar rats into six groups: control (C), Pera orange juice (PO), Moro orange juice (MO), doxorubicin (D), doxorubicin + Pera orange juice (DPO), and doxorubicin + Moro orange juice (DMO). Groups PO and DPO received Pera orange juice, MO and DMO received Moro orange juice, and C and D received water with maltodextrin (100 g/L) for 4 wk. Subsequently, groups D, DPO, and DMO received 20 mg/kg doxorubicin and C, PO, and MO received saline. Echocardiogram and euthanasia were performed 48 h after doxorubicin injection. Juice and animal-serum flavonoid identification and quantification were evaluated by liquid chromatography/electrospray ionization multistage mass spectrometry. Oxidative stress and myocardial metabolism were evaluated by spectrophotometry. RESULTS: Systolic and diastolic left ventricular dysfunction increased oxidative stress and pathologic changes in myocardial energy metabolism of rats treated with doxorubicin. Intake of both orange juices improved left ventricular function, decreased oxidative stress, and attenuated the myocardial energy metabolism changes. Moro orange juice had a more pronounced effect than Pera orange juice in glutathione peroxidase activity, citrate synthase, and ß-hydroxyacyl-CoA dehydrogenase activity. CONCLUSIONS: Pera and Moro orange juices attenuated cardiac remodeling induced by doxorubicin, improved myocardial energy metabolism, and attenuated oxidative stress. However, Moro orange juice was more effective than Pera orange juice in modifying energy metabolism.

RESUMO

BACKGROUND: The objective of this study was to evaluate the performance of the Framingham risk score (FRS) and risk score by the American College of Cardiology/American Heart Association (SR ACC/AHA) in predicting mortality of patients ten years after acute coronary syndrome (ACS). METHODS: This is a retrospective cohort study that included patients aged ≥ 18 years with ACS who were hospitalized at the Coronary Intensive Care Unit (ICU) of the Botucatu Medical School Hospital from January 2005 to December of 2006. RESULTS: A total of 447 patients were evaluated. Of these, 118 were excluded because the mortality in 10 years was not obtained. Thus, 329 patients aged 62.9 ± 13.0 years were studied. Among them, 58.4% were men, and 44.4% died within ten years of hospitalization. The median FRS was 16 (14-18) %, and the ACC/AHA RS was 18.5 (9.1-31.6). Patients who died had higher values of both scores. However, when we classified patients at high cardiovascular risk, only the ACC/AHA RS was associated with mortality (p <0.001). In the logistic regression analysis, both scores were associated with mortality at ten years (p <0.001). CONCLUSIONS: Both FRS and SR ACC/AHA were associated with mortality. However, for patients classified as high risk, only the ACC/AHA RS was associated with mortality within ten years.

RESUMO OBJETIVO Avaliar a performance do escore de risco de Framingham (ERF) e do escore proposto pela American College of Cardiology/American Heart Association (ER ACC/AHA) em predizer a mortalidade em pacientes dez anos após síndrome coronariana aguda (SCA). MÉTODOS Trata-se de um estudo de coorte retrospectivo que incluiu pacientes com idade ≥18 anos, com SCA, que estiveram internados na Unidade de Terapia Intensiva Coronariana (UTI) do Hospital das Clínicas de Botucatu, no período de janeiro de 2005 a dezembro de 2006. RESULTADOS Foram avaliados 447 pacientes. Destes, 118 foram excluídos, pois a mortalidade em dez anos não foi obtida. Logo, 329 pacientes com idade de 62,9±13,0 anos foram estudados. Dentre eles, 58,4% eram homens e 44,4% morreram no período de dez anos após a internação. A mediana do ERF foi de 16 (14-18)%, e do ER ACC/AHA foi 18,5 (9,1-31,6)%. Os pacientes que evoluíram a óbito apresentaram maiores valores dos escores. No entanto, quando classificamos os pacientes em alto risco cardiovascular, apenas o ER ACC/AHA foi associado com a mortalidade (p<0,001). Na análise de regressão logística, ambos os escores foram associados com a mortalidade em dez anos (p<0,001). CONCLUSÕES Tanto o ERF quanto o ER ACC/AHA foram associados com a mortalidade. No entanto, para os pacientes classificados como alto risco, apenas o ER ACC/AHA foi associado com a mortalidade em dez anos.

RESUMO

BACKGROUND: Oxidative stress is one potential mechanism that explain the direct effects of smoking on cardiac remodeling process. However, no study has compared different myocardial products of macromolecule oxidation after tobacco smoke exposure. Thus, the aim of this study was to investigate the lipid hydroperoxide (LH) levels, protein carbonyl concentrations and DNA damage in cardiac tissue of rats exposed to tobacco smoke. METHODS: Male Wistar rats were divided into two groups: group C (control, n = 14) composed of animals not exposed to cigarette smoke; group ETS (exposed to tobacco smoke, n = 14) composed by animals exposed to cigarette smoke. The animals were exposed to 2 month of ETS and morphological, biochemical and functional analyses were performed. RESULTS: Cardiac cotinine levels were elevated in the ETS group. In addition, the myocyte cross-sectional area was higher in the ETS group. (C = 266.6 ± 23.2 µm2 and ETS = 347.5 ± 15.1 µm2, p <  0.001). Cardiac LH was higher in the ETS group than in group C (C = 196.4 ± 51.5 nmol/g and ETS = 331.9 ± 52.9 nmol/g, p <  0.001). However, there were no between-group differences in cardiac protein carbonyl concentration or DNA damage. CONCLUSIONS: Therefore, our results suggest that, in this model, lipid damage is a good marker of oxidative damage during the cardiac remodeling process induced by 2 months of exposure to tobacco smoke.

RESUMO

The objective of this study was to investigate the influence of Spondias mombin (SM) supplementation on the cardiac remodelling process induced by exposure to tobacco smoke (ETS) in rats. Male Wistar rats were divided into 4 groups: group C (control, n = 20) comprised animals not exposed to cigarette smoke and received standard chow; group ETS (n = 20) comprised animals exposed to cigarette smoke and received standard chow; group ETS100 (n = 20) received standard chow supplemented with 100 mg/kg body weight/d of SM; and group ETS250 (n = 20) received standard chow supplemented with 250 mg/kg body weight/d of SM. The observation period was 2 months. The ETS animals had higher values of left cardiac chamber diameters and of left ventricular mass index. SM supplementation attenuated these changes. In addition, the myocyte cross-sectional area (CSA) was lower in group C compared with the ETS groups; however, the ETS250 group had lower values of CSA compared with the ETS group. The ETS group also showed higher cardiac levels of lipid hydroperoxide (LH) compared with group C; and, groups ETS100 and ETS250 had lower concentrations of LH compared with the ETS group. Regarding energy metabolism, SM supplementation decreased glycolysis and increased the ß-oxidation and the oxidative phosphorylation. There were no differences in the expression of Nrf-2, SIRT-1, NF-κB, interferon-gamma and interleukin 10. In conclusion, our results suggest that ETS induced the cardiac remodelling process. In addition, SM supplementation attenuated this process, along with oxidative stress reduction and energy metabolism modulation.

RESUMO

Anemia is a prevalent comorbidity and marker of a poorer prognosis in patients with heart failure (HF). Its clinical relevance, as well as its pathophysiology and the clinical management of these patients are important subjects in the specialized literature. In the present review, we describe the current concepts on the pathophysiology of anemia in HF, its diagnostic criteria, and the recommendations for iron supplementation. Also, we make a critical analysis of the major studies showing evidences on the benefits of this supplementation. The four main components of anemia are addressed: chronic disease, dilutional, "renal" and malabsorption. In patients with HF, the diagnostic criteria are the same as those used in the general population: serum ferritin levels lower than 30 mcg/L in patients without kidney diseases and lower than 100 mcg/L or serum ferritin levels between 100-299 mcg/L with transferring saturation lower than 20% in patients with chronic kidney diseases. Finally, the therapeutic possibilities for anemia in this specific patient population are discussed.

RESUMO

A anemia é uma comorbidade prevalente e marcadora de pior prognóstico em pacientes com insuficiência cardíaca (IC). Sua relevância clínica, bem como a fisiopatologia e abordagem terapêutica nesses pacientes são temas de destaque na literatura especializada. Nessa revisão são descritos os conceitos atuais sobre a fisiopatologia da anemia na IC, os critérios diagnósticos e as indicações da suplementação de ferro, ao mesmo tempo em que são analisados criticamente os principais estudos que ofereceram evidências sobre os benefícios dessa suplementação. São abordados os quatro componentes principais da anemia: doença crônica, dilucional, "renal" e disabsortiva. Nos pacientes com IC, os critérios para o diagnóstico são os mesmos utilizados na população geral: níveis de ferritina sérica inferiores a 30 mcg/L em pacientes não nefropatas e menores que 100 mcg/L ou ferritina sérica entre 100-299 mcg/L com saturação de transferrina menor que 20% em pacientes com doença renal crônica. Finalmente, são discutidas as possibilidades terapêuticas da anemia nessa população específica de pacientes.

RESUMO

OBJECTIVES: The prevalence of electrocardiographic and echocardiographic abnormalities in chronic obstructive pulmonary disease according to disease severity has not yet been established. The aim of this study was to assess the prevalence of electrocardiographic and echocardiographic abnormalities in chronic obstructive pulmonary disease patients according to disease severity. METHODS: The study included 25 mild/moderate chronic obstructive pulmonary disease patients and 25 severe/very severe chronic obstructive pulmonary disease patients. All participants underwent clinical evaluation, spirometry and electrocardiography/echocardiography. RESULTS: Electrocardiography and echocardiography showed Q-wave alterations and segmental contractility in five (10%) patients. The most frequent echocardiographic finding was mild left diastolic dysfunction (88%), independent of chronic obstructive pulmonary disease stage. The proportion of right ventricular overload (p<0.05) and blockage of the anterosuperior division of the left bundle branch were higher in patients with greater obstruction. In an echocardiographic analysis, mild/moderate chronic obstructive pulmonary disease patients showed more abnormalities in segmental contractility (p<0.05), whereas severe/very severe chronic obstructive pulmonary disease patients showed a higher prevalence of right ventricular overload (p<0.05), increased right cardiac chamber (p<0.05) and higher values of E-wave deceleration time (p<0.05). Age, sex, systemic arterial hypertension, C-reactive protein and disease were included as independent variables in a multiple linear regression; only disease severity was predictive of the E-wave deceleration time [r²=0.26, p=0.01]. CONCLUSION: Chronic obstructive pulmonary disease patients have a high prevalence of left ventricular diastolic dysfunction, which is associated with disease severity. Because of this association, it is important to exclude decompensated heart failure during chronic obstructive pulmonary disease exacerbation.

RESUMO

BACKGROUND: Inadequate dialysis causes accumulation of toxic residues that may lead to the development of dialysis-associated pericardial effusion, but several other factors could be associated with this abnormality. The purpose of this study was to evaluate clinical risk factors to asymptomatic pericardial effusion in peritoneal dialysis. METHODS: This cross-sectional study included 34 patients aged ≥ 18 years on peritoneal dialysis for at least 3 months, who showed no symptomatic pericardial effusion, hepatic cirrhosis, neoplasias, lupus or amputations, none in minoxidil use. Asymptomatic pericardial effusion was diagnosed by echocardiography. Risk factors were evaluated by logistic regression and Roc curve. Significance level was set at P < 0.05. RESULTS: Patient age was 51 ± 15.9 years. Of the 34 patients enrolled, 16 were men and 11 diabetic. Five of them presented pericardial effusion. Logistic regression identifies low hemoglobin level (RR 0.454 CI 95%: 0.225-0.913; P = 0.027), low phase angle (RR 0.236 CI 95%: 0.057-0.984; P = 0.048) and low Kt/V (RR 0.001 CI 95%: 0.0-0.492; P = 0.03) as risk factors to pericardial effusion. Roc curve showed that hemoglobin levels below 12.2 g/dL, Kt/V lower than 1.9 and phase angle lower than 4.5° were the best cutoffs to predict pericardial effusion. Four patients showed these three parameters in the unfavorable range, and all these four patients presented pericardial effusion. The other patient with pericardial effusion had two of these parameters reduced. CONCLUSIONS: These findings corroborate the hypothesis that uremia plays a significant role in the pathogenesis of dialysis-associated pericardial effusion.

RESUMO

OBJETIVO: Identificar determinantes do estado de hidratação de pacientes em diálise peritoneal crônica, bem como investigar os efeitos da sobrecarga líquida sobre o estado nutricional. MÉTODOS: Foi feito estudo transversal, realizado em 2006, avaliando 27 pacientes em diálise peritoneal crônica, acompanhados no Hospital das Clínicas da Faculdade de Medicina de Botucatu (SP), quanto a parâmetros clínicos, dialíticos, laboratoriais, antropométricos e de bioimpedância elétrica. Para avaliar a influência de parâmetros sobre o estado de hidratação empregou-se modelo de regressão linear múltipla. A amostra foi estratificada quanto ao estado de hidratação pela relação entre água extracelular e água corporal total (0,47 para homens e 0,52 para mulheres), parâmetros obtidos por meio de bioimpedância elétrica. Comparações foram realizadas por análise de covariância, Mann-Whitney, Qui-quadrado ou teste exato de Fisher. Considerou-se significância estatística quando p≤0,05. RESULTADOS: Pacientes com maior volume urinário e em modalidade dialítica automatizada apresentaram melhor estado de hidratação. Pacientes com maior sobrecarga líquida, comparados àqueles com menor sobrecarga, apresentaram menor ângulo de fase (M=4,2, DP=0,9 vs M=5,7, DP=0,7º; p=0,006), menor albumina (M=3,06, DP=0,46 vs M=3,55, DP=0,52g/dL; p=0,05) e maior por cento prega cutânea tricipital (M=75,3, DP=36,9 vs M=92,1, DP=56,9 por cento; p=0,058), sem outras evidências antropométricas. CONCLUSÃO: Pode-se sugerir que os níveis reduzidos de albumina e ângulo de fase nos pacientes com maior sobrecarga líquida não estiveram relacionados a pior estado nutricional. Para o diagnóstico nutricional em vigência de sobrecarga líquida, deve-se considerar o conjunto de variáveis obtidas por diversos métodos, buscando relacioná-las e interpretá-las de maneira abrangente, possibilitando um diagnóstico nutricional fidedigno.


OBJECTIVE: This study identified determinants of the hydration status of chronic peritoneal dialysis patients and investigated the effects of fluid overload on their nutritional status. METHODS: A cross-sectional study was conducted in 2006 to evaluate 27 chronic peritoneal dialysis patients from the Dialysis Center of the Medical School Hospital of Botucatu (SP), considering clinical, dialytic, laboratory, anthropometric and bioimpedance parameters. A linear multiple regression model was used to evaluate the influence of these parameters on hydration status. The sample was stratified according to hydration status, given by the ratio between extracellular water and total body water (0.47 for males and 0.52 for females), obtained by bioelectrical impedance. Analysis of covariance, Mann-Whitney test, chi-square test, and Fisher's exact test were used for making comparisons. The significance level was set at 5 percent (p≤0.05). RESULTS: Patients with greater urine volume and receiving automatic dialysis presented better hydration status. Patients with higher fluid overload, compared with those with lower overload, presented lower phase angle (M=4.2, SD=0.9 vs. M=5.7, SD=0.7º; p=0.006), lower albumin levels (M=3.06, SD=0.46 vs. M=3.55, SD=0.52g/dL; p=0.05), and higher percentage of triceps skinfold thickness (M=75.3, SD=36.9 vs. M= 92.1, SD=56.9; p=0.058). No other anthropometric differences were observed. CONCLUSION: Low levels of albumin and phase angle in patients with higher fluid overload were not related to worse nutritional status. This result suggests that one must consider the set of variables obtained by many methods and relate and interpret them comprehensively in order to obtain a reliable nutritional diagnosis of patients with fluid overload.

RESUMO

Objetivo: Avaliar os efeitos agudos de CPAP na função diastólica ventricular esquerda e tolerância ao exercício em pacientes com insuficiência cardíaca compensada (IC). Métodos: Série de casos (onze pacientes), classe funcional II/III (NYHA). Foram realizados o Teste de caminhada de 6 minutos (TC6), antes e após CPAP (30 minutos; 10 cm H2O), e o ecocardiograma antes e no final do período de CPAP. Os resultados foram comparados pelos testes t pareado ou Wilcoxon, p<0.05. Resultados: CPAP diminuiu a fadiga pré-TC6 (p=0,016) e a dispnéia pós-TC6 (p=0,012). Houve redução do tempo de desaceleração da onda E(p=0,006). Conclusão: CPAP melhora a tolerância aos esforços físicos, em pacientes com IC, provavelmente devido ao efeito na função diastólica ventricular esquerda.

RESUMO

Introdução: A doença renal crônica apresenta elevado risco cardiovascular. dados da população geral associam as doenças cardiovasculares a baixo nível de escolaridade, porém nehum trabalho avaliou essa associação entre pacientes em hemodiálise. objetivo: Avaliar a associação entre Botucatu (UNESP). dados clínicos, laboratoriais e ecocardiográficos foram extraídos dos prontuários. os pacientes foram divididos em dois grupos de acordo com a mediana da escolaridade: o grupo I foi constituído por pacientes com escolaridade <- três anos, e grupo II por pacientes com escolaridade superior a três anos. resultados: pressão arterial, ganho de peso interdialítico e variáveis com diferença estatística entre os dois grupos ao nível de p< 0,2 foram selecionadas para análise múltipla. Na análise múltipla, associações independentes foram consideradas ao nível de p< 0,05. A média de idade dos pacientes foi 57+- 12.8 anos, 46 pacientes eram homens (57%) e 53 eram brancos (67%). As variáveis selecionadas para análise múltipla foram: idade (p= 0,004), anos de escolaridade (p, 0,0001), índice de massa corpórea (p= 0,124), diâmetro do ventrículo esquerdo (p= 0,048) e índice de massa ventricular (p= 0,006). As drogas anti-hipertensivas empregadas foram similares em ambos os grupos. A pressão sistólica (p=0,006) e a escolaridade (p=0,047) apresentaram correlação significativa e independente com índice de massa ventricular. Conclusão: Em pacientes em hemodiálise, houve correlação da massa do ventrículo esquerdo não apenas com a pressão arterial, mas também com o nível educacional.


Introduction: Chronic kidney disease has a high cardiovascular risk. data from the general population associated cardiovascular disease to low levels of schooling, but match any study evaluated the association between hemodialysis patients. Objective: To evaluate the association between Botucatu (UNESP). clinical, laboratory and echocardiographic findings were extracted from medical records. Patients were divided into two groups according to the median education level: group I comprised patients with educational <- three years, and group II patients with higher education for three years. results: blood pressure, interdialytic weight gain and variable with a statistical difference between the two groups at p <0.2 were selected for multivariate analysis. On multivariate analysis, independent associations were considered at p <0.05. The average patient age was 57 + - 12.8 years, 46 patients were men (57%) and 53 were white (67%). Variables selected for multivariate analysis were age (p = 0.004), years of schooling (p, 0.0001), body mass index (p = 0.124), left ventricular diameter (p = 0.048) and left ventricular mass indeThe antihypertensive drugs used were similar in both groups. Systolic pressure (p = 0.006) and education (p = 0.047) correlated significantly and independently with left ventricular mass index. Conclusion: In hemodialysis patients, there was a correlation between left ventricular mass with not only blood pressure but also to the educational level.x (p = 0.006).

RESUMO

INTRODUCTION: Chronic renal disease is associated with a high cardiovascular risk. Data from the general population associate cardiovascular diseases with low educational level, but no study has evaluated this association in patients on hemodialysis. OBJECTIVE: This study aimed at evaluating the association between educational level, hypertension, and left ventricular hypertrophy in patients on chronic hemodialysis. METHODS: A standard socioeconomic questionnaire was applied to 79 hemodialysis patients at the Hospital das Clínicas da Faculdade de Medicina de Botucatu, state of São Paulo. Clinical, laboratory and echocardiographic data were obtained from medical records. The patients were divided into two groups according to the median educational level, as follows: G1, patients with three or less years of schooling; G2, patients with more than three years of schooling. RESULTS: Blood pressure, interdialytic weight gain, and variables statistically different in the two groups (p < 0.2) underwent multiple analysis. Independent associations were stated with p < 0.05 in multiple analysis. The mean age of patients was 57 ± 12.8 years, 46 were males (57%), and 53 white (67%). The variables selected for multiple analysis were: age (p = 0.004); educational level (p < 0.0001); body mass index (p = 0.124); left ventricular diameter (p = 0.048); and left ventricular mass index (p = 0.006). Antihypertensive drugs were similar in both groups. Systolic blood pressure (p = 0.006) and years of schooling (p = 0.047) had a significant and independent correlation with left ventricular mass index. CONCLUSION: In hemodialysis patients, left ventricular mass associated not only with blood pressure but also with educational level.

RESUMO

As diferenças de comportamento das doenças cardiovasculares associadas ao gênero ganharam relevância nos últimos anos, principalmente no que se refere às peculiaridades relacionadas às pacientes do sexo feminino. Um fator interessante é o menor conhecimento das mulheres quanto ao risco que essas doenças trazem a sua saúde, contribuindo para o diagnóstico menos precose e pior prognóstico. De forma geral, a resposta aos agentes agressores cardíacos pode ser bastante distinta quando se comparam homens e mulheres. Espera-se que a compreensão dessas peculiaridades tenha impacto positivo no diagnóstico, no tratamento e no prognóstico de mulheres com cardiopatias. A literatura não apresenta muitas evidências sobre as particularidades das cardiomiopatias nas mulheres. No entanto, o cardiologista deve estar atento para reconhecer as diferenças na apresentação clínica e na evolução relacionadas ao gênero. Nesta revisão serão abordadas as cardiomiopatias dilatadas, hipertróficas, periparto e alcoólica (primárias). Dentre as secundárias serão descritas algumas peculiaridades do comprometimento cardíaco na paciente com amiloidose, diabetes melito, doenças autoimunes e cardiotoxicidade induzida por terapia antitumoral.


Gender-related differences have gained relevance in cardiovascular diseases in recent years, especially regarding women-related peculiarities. An interesting fact is the lesser knowledge of women on the risk that cardiovascular diseases pose to their health, thus contributing to delaying diagnosis and worse prognosis. In general, men and women have very different responses to cardiac aggressive agents. It is expected that the understanding of these peculiarities may have a positive impact on the diagnosis, treatment and prognosis of women with heart diseases. Literature data do not provide broad evidences on the particularities of cardiomyopathies in women. However, the cardiologist must pay close attention to identify gender-related differences in the clinical presentation and clinical course. This review will address primary dilated, hypertrophic, peripartum and alcoholic cardiomyopathies. Peculiarities of secondary cardiomyopathy in patients with amyloidosis, diabetes mellitus, autoimmune diseases and cardiotoxicity induced by anti-tumoral therapy will also be reported.

RESUMO

INTRODUCTION: The present study examines cardiovascular risk factor profiles and 24-month mortality in patients with symptomatic peripheral arterial disease. DESIGN STUDY: Prospective observational study including 75 consecutive patients with PAD (67 +/- 9.7 years of age; 52 men and 23 women) hospitalized for planned peripheral vascular reconstruction. Doppler echocardiograms were performed before surgery in 54 cases. Univariate analyses were performed using Student's t-test or Fisher's exact test. Survival analysis at 24-month follow-up was performed using the Cox regression model and Kaplan-Meier method including age and chronic use of aspirin as covariates. Survival curves were compared using the log-rank test. RESULTS: Hypertension and smoking were the most frequent risk factors (52 cases and 51 cases, respectively), followed by diabetes (32 cases). Undertreated dyslipidemia was found in 26 cases. Fasting glycine levels (131 +/- 69.1 mg/dl) were elevated in 29 cases. Myocardial hypertrophy was found in 18 out of 54 patients. Thirty-four patients had been treated with aspirin. Overall mortality over 24 months was 24% and was associated with age (HR: 0.064; CI95: 0.014-0.115; p=0.013) and lack of use of aspirin, as no deaths occurred among those using this drug (p<0.001). No association was found between cardiovascular death (11 cases) and the other risk factors. CONCLUSION: There is a high prevalence of uncontrolled (treated or untreated) cardiovascular risk factors in patients undergoing planned peripheral vascular reconstruction, and chronic use of aspirin is associated with reduced all-cause mortality in these patients.

RESUMO

A cardiomiopatia periparto é rara e se caracteriza por disfunção ventricular esquerda e sintomas de insuficiência cardíaca, que se manifestam no período periparto em mulheres previamente saudáveis. A incidência de cardiomiopatia periparto varia de 1 em 1.300 a 1 em 1.500 gestações. A etiologia da cardiomiopatia periparto ainda é desconhecida, mas foram propostas várias causas, como viral, autoimune e idiopática. Os critérios diagnósticos consistem no desenvolvimento da síndrome de insuficiência cardíaca no último mês de gestão ou nos primeiros cinco meses pós-parto, ausência de um causa determinável de insuficiência cardíaca, e ausência de doença cardíaca reconhecível anterior ao último mês de gestação. Também fazem parte dos critérios diagnósticos os seguintes achados ecocardiográficos: fração de ejeção < 45 por cento e/ou fração de encurtamento < 30 por cento ou dimensão diastólica final do ventrículo esquerdo...
