Adequação do consumo de ácidos graxos entre pacientes em prevenção cardiovascular secundária / Adequacy of Fatty Acids Consumption Among Individuals in Secondary Cardiovascular Prevention

FUNDAMENTO: A adesão à uma alimentação adequada em macronutrientes é fundamental para a prevenção secundária de doenças cardiovasculares. OBJETIVO: Avaliar a prevalência de adesão às recomendações de consumo de ácidos graxos para prevenção e tratamento de doenças cardiovasculares, e estimar se a presença de determinados fatores de risco cardiovascular estaria associada à adesão. MÉTODOS: Estudo transversal com os dados de linha de base de 2358 participantes do estudo "Brazilian Cardioprotective Nutritional Program Trial". Dados de consumo alimentar, e fatores de risco cardiovascular foram avaliados. Foi considerada, de acordo com a Sociedade Brasileira de Cardiologia, uma ingestão adequada de ácidos graxos poli-insaturados (AGPI) ≥10% do consumo total de energia diária, para ácidos graxos monoinsaturados (AGM), 20% e para ácidos graxos saturados (AGS), <7%. Na análise estatística foi considerando nível de significância de 5%. RESULTADOS: Nenhum participante aderiu a todas as recomendações de forma simultânea e mais da metade (1482 [62,9%]) não aderiu a nenhuma recomendação. A adesão exclusivamente à recomendação de AGS foi a mais prevalente, sendo cumprida por 659 (28%) dos participantes, seguida da adesão exclusivamente à recomendação de AGP (178 [7,6%]) e de AGM (5 [0,2%]). Não houve associação entre o número de comorbidades e a adesão às recomendações nutricionais (p =0,269). Os participantes da região Nordeste do país apresentaram maior proporção de adesão às recomendações para consumo de AGS (38,42%), e menor para ingestão de AGPI (3,52%) (p <0,001) em comparação às demais. CONCLUSÕES: Na amostra avaliada, evidenciou-se baixa adesão às recomendações nutricionais para consumo de ácidos graxos.

Accuracy of the Verbal Autopsy questionnaire in the diagnosis of COVID-19 deaths in a Brazilian capital

ABSTRACT The Verbal Autopsy (VA) is a questionnaire about the circumstances surrounding a death. It was widely used in Brazil to assist in postmortem diagnoses and investigate excess mortality during the Coronavirus Disease 2019 (COVID-19) pandemic. This study aimed to determine the accuracy of investigating acute respiratory distress syndrome (ARDS) using VA. This is a cross-sectional study with prospective data collected from January 2020 to August 2021 at the Death Verification Service of Sao Luis city, Brazil. VA was performed for suspected COVID-19 deaths, and one day of the week was randomly chosen to collect samples from patients without suspected COVID-19. Two swabs were collected after death and subjected to reverse transcription-polymerase chain reaction (RT-PCR) for SARS-CoV-2 detection. Of the 250 cases included, the VA questionnaire identified COVID-19-related ARDS in 67.2% (52.98% were positive for COVID-19). The sensitivity of the VA questionnaire was 0.53 (0.45-0.61), the specificity was 0.75 (0.64-0.84), the positive predictive value was 0.81 (0.72-0.88), and the negative predictive value was 0.44 (0.36-0.53). The VA had a lower-than-expected accuracy for detecting COVID-19 deaths; however, because it is an easily accessible and cost-effective tool, it can be combined with more accurate methods to improve its performance.

Metabolic Syndrome and Risk of Cardiovascular Diseases in Female Breast Cancer Survivors

Abstract Background The implementation of intensive therapy protocols increases the probability of adverse events in patients with breast cancer (BC). Components of metabolic syndrome (MS) are among these events. Objective To verify the prevalence of MS and cardiovascular disease (CVD) risk in female BC survivors. Materials and Methods This is a descriptive, observational, cross-sectional study. Our sample comprised 60 women without BC (G1) and 60 women who had survived BC (G2). We collected sociodemographic, anthropometric, tumor, and clinical data. After variable analysis, the participants received positive or negative MS diagnoses and a 10-year CVD risk stratification. The significance level adopted for the analyses was 5% ( p < 0.05) and the confidence interval (CI) was 95%. For comparing categorical data, we used the chi-squared, Fisher's exact, or G tests; for comparing continuous data, we used the parametric Student's t-test and the non-parametric Mann-Whitney test. Results Both groups presented overweight and an increased waist-to-hip ratio. Weight, body mass index, abdominal circumference, hip circumference, and low-density cholesterol were variables that presented statistically significant differences between groups. MS was diagnosed in 32% of women in G1 and 45% of those in G2. Regarding the 10-year risk for CVD, most women were in the low-risk stratum: the mean total risk of CVD occurrences was 7.48% in G1 and 7.70% in G2. Conclusion We observed a higher prevalence of MS among women who survived BC, possibly due to overweight, as well as a low 10-year risk for CVD after cancer treatment. Although we did not observe a statistically significant difference, we suggest the adoption of a healthy lifestyle and rigorous control of cardiometabolic risk factors.

Implications for clinical practice from a multicenter survey of heart failure management centers

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.

Doença de Coronavírus-19 e o Miocárdio / Coronavirus Disease 2019 and the Myocardium

Resumo A infecção pelo coronavírus denominada COVID-19 promoveu crescente interesse de cardiologistas, emergencistas, intensivistas e pesquisadores, pelo estudo do acometimento miocárdico partindo de diferentes formas clínicas decorrentes de desmodulação imunoinflamatória e neuro-humoral.O acometimento miocárdico pode ser mínimo e apenas identificado a partir de alterações eletrocardiográficas, principalmente por aumento de troponinas cardíacas, ou no outro lado do espectro pelas formas de miocardite fulminante e síndrome de takotsubo.A descrição de provável miocardite aguda tem sido comumente apoiada pela observação da troponina elevada em associação com disfunção. A clássica definição de miocardite, respaldada pela biópsia endomiocárdica de infiltrado inflamatório é rara, e foi observada em um único relato de caso até o momento, não se identificando o vírus no interior dos cardiomiócitos.Assim, o fenômeno que se tem documentado é de injúria miocárdica aguda, sendo obrigatório afastar doença coronária obstrutiva a partir da elevação de marcadores de necrose miocárdica, associada ou não à disfunção ventricular, provavelmente associada à tempestade de citoquinas e outros fatores que podem sinergicamente promover lesão miocárdica, tais como hiperativação simpática, hipoxemia, hipotensão arterial e fenômenos trombóticos microvasculares.Fenômenos inflamatórios sistêmicos e miocárdicos após infecção viral estão bem documentados, podendo evoluir para remodelamento cardíaco e disfunção miocárdica. Portanto, será importante a cardiovigilância desses indivíduos para monitorar o desenvolvimento do fenótipo de miocardiopatia dilatada.A presente revisão apresenta os principais achados etiofisiopatológicos, descrição da taxonomia desses tipos de acometimento cardíaco e sua correlação com as principais formas clínicas do componente miocárdico presente nos pacientes na fase aguda de COVID-19.

Abstract Infection with the coronavirus known as COVID-19 has promoted growing interest on the part of cardiologists, emergency care specialists, intensive care specialists, and researchers, due to the study of myocardial involvement based on different clinical forms resulting from immunoinflammatory and neurohumoral demodulation.Myocardial involvement may be minimal and identifiable only by electrocardiographic changes, mainly increased cardiac troponins, or, on the other side of the spectrum, by forms of fulminant myocarditis and takotsubo syndrome.The description of probable acute myocarditis has been widely supported by the observation of increased troponin in association with dysfunction. Classical definition of myocarditis, supported by endomyocardial biopsy of inflammatory infiltrate, is rare; it has been observed in only one case report to date, and the virus has not been identified inside cardiomyocytes.Thus, the phenomenon that has been documented is acute myocardial injury, making it necessary to rule our obstructive coronary disease based on increased markers of myocardial necrosis, whether or not they are associated with ventricular dysfunction, likely associated with cytokine storms and other factors that may synergistically promote myocardial injury, such as sympathetic hyperactivation, hypoxemia, arterial hypotension, and microvascular thrombotic phenomena.Systemic inflammatory and myocardial phenomena following viral infection have been well documented, and they may progress to cardiac remodeling and myocardial dysfunction. Cardiac monitoring of these patients is, therefore, important in order to monitor the development of the phenotype of dilated myocardiopathy.This review presents the main etiological and physiopathological findings, a description of the taxonomy of these types of cardiac involvement, and their correlation with the main clinical forms of the myocardial component present in patients in the acute phase of COVID-19.

Síndrome metabólica e resistência insulínica pelo Homa-IR no climatério / Metabolic syndrome and insulin resistance by HOMA-IR in menopause

Fundamento: Síndrome metabólica é um importante fator de risco cardiovascular, e sua prevalência aumenta após a menopausa. Ainda é incerto, porém, se a menopausa é fator de risco independente para a síndrome metabólica. Uma das bases fisiopatológicas para síndrome metabólica é a resistência insulínica, que pode ser calculada pelo método Homeostatic Model Assessment-Insulin Resitance (HOMA-IR), sendo pouco conhecida a relação entre resistência insulínica e menopausa. Objetivos: Avaliar a relação entre síndrome metabólica e resistência insulínica em mulheres climatéricas. Métodos: Estudo descritivo, que avaliou 150 mulheres, com idades entre 40 e 65 anos, atendidas em um ambulatório de ginecologia em um hospital terciário público, entre maio e dezembro de 2013. A amostra foi dividida em dois grupos, sendo o Grupo I com pacientes na pré-menopausa e o II com pacientes na pós-menopausa. Foi avaliada a presença de síndrome metabólica, bem como de seus componentes, além da ocorrência de resistência insulínica nos dois grupos. A associação do estado menopausal e as variáveis estudadas foi realizada com os testes Mann-Whitney, qui quadrado e exato de Fisher. O nível de significância foi de 5%. A análise estatística foi feita por meio do STATA 12.0. Resultados: A síndrome metabólica foi mais prevalente nas mulheres pós-menopausa, bem como todos seus componentes tiveram maior frequência também nesse grupo. As mulheres pós-menopausa também apresentaram maior prevalência de resistência insulínica, mas não foi observada relação estatística entre os achados. Conclusão: O estado menopausal não se associou significativamente com síndrome metabólica e resistência insulínica. A resistência insulínica foi considerada fator de risco independente para o desenvolvimento de síndrome metabólica apenas no grupo pós-menopausa

Background: Metabolic syndrome is an important cardiovascular risk factor, and its prevalence increases after menopause. However, it is still uncertain whether menopause is an independent risk factor for metabolic syndrome. One of the pathophysiological basis for metabolic syndrome is insulin resistance, which can be calculated by the Homeostatic Model Assessment-Insulin Resistance (HOMA-IR) method, and the association between insulin resistance and menopause is little known. Objective: To evaluate the association between metabolic syndrome and insulin resistance in menopausal women. Method: Descriptive study, which evaluated 150 women, aged 40 to 65, treated at a Gynecology Outpatient Clinic of a tertiary public hospital, from May to December of 2013. The sample was divided into two groups: Group I, comprising women in the premenopausal period and Group II, comprising women in the post-menopausal period. The presence of metabolic syndrome and its components were evaluated, as well as occurrence of insulin resistance in both groups. The association of menopausal status and the assessed variables was assessed using the Mann-Whitney, Chi-square and Fisher's exact tests. The significance level was set at 5%. The statistical analysis was performed using STATA 12.0. Results: Metabolic syndrome and its components were more prevalent in postmenopausal women. Postmenopausal women also had a higher prevalence of insulin resistance, but no statistical association was observed between the findings. Conclusion: The menopausal status was not significantly associated with metabolic syndrome and insulin resistance. Insulin resistance was considered an independent risk factor for the development of metabolic syndrome only in the postmenopausal group

Fatores de risco cardiovascular em mulheres climatéricas com doença arterial coronariana / Cardiovascular risk factors in climacteric women with coronary artery disease

Fundamentos: O aumento da incidência de doenças cardiovasculares em mulheres ocorre durante o período do climatério, especialmente após a menopausa. Objetivo: O objetivo deste estudo foi identificar fatores de risco cardiovasculares entre as mulheres climatéricas com e sem doença arterial coronariana (DAC). Métodos: Trata-se de estudo transversal realizado no Serviço de Hemodinâmica do Hospital Universitário da Universidade Federal do Maranhão, no período de março de 2012 a julho de 2013. Foram incluídas 31 mulheres climatéricas que compareceram ao setor para realização do cateterismo cardíaco, separadas em grupos após resultados do cateterismo, Grupo I (com DAC) e Grupo II (sem DAC). Análise estatística: as variáveis categóricas foram descritas por meio de frequências e porcentagem, as numéricas por meio de média ± desvio padrão ou mediana (Quartil.3 ­ Quartil.1); o teste Shapiro-Wilk para verificar a normalidade dos dados quantitativos, o teste Exato de Fisher para comparações de dados categóricos; para dados contínuos o Test-T para amostras não pareadas ou o Mann-Whitney; foi considerado estatisticamente significativo o valor de p < 0,05. Resultados: Avaliaram-se grupos com DAC (n = 13) e sem DAC (n = 18), os resultados apontaram média de idade entre os grupos de 57,92 ± 5,15 e 51,72 ± 4,63 anos, respectivamente; dentre os fatores de risco cardiovasculares, os mais prevalentes entre as mulheres com DAC foram: a menopausa (84,62%), a hipertensão arterial sistêmica (HAS) (69,23%) e o sedentarismo (69,23). Conclusão: Concluiu-se que, além da menopausa propriamente dita, a HAS e o sedentarismo foram os fatores de risco cardiovasculares mais prevalentes entre as mulheres com DAC

Background: The increased incidence of cardiovascular disease in women occurs during the climacteric period, especially after menopause. Objective: The aim of this study was to identify risk factors among climacteric women with and without coronary artery disease (CAD). Method: This cross-sectional study was performed in the Catheterization Laboratory at the Federal University Hospital of Maranhão, in the Northeast region of Brazil, between March 2012 and July 2013. We included 31 climacteric women who went to the care center for cardiac catheterization. They were divided into groups after catheterization results: Group I (with DAC) and Group II (without CAD). Statistical analysis: Categorical variables were described by means of frequencies and percentages, numerical variables by mean ± standard deviation or median (Quartile.3 - Quartile.1); the Shapiro-Wilk test was used to verify the normality of quantitative data. Fisher's exact test was used for categorical data comparisons. For continuous data, we used Student's test or the Mann-Whitney for unpaired samples; statistical significance was set at p < 0.05. Results: We evaluated groups with CAD (n = 13) and without CAD (n = 18). The results showed a mean age between the groups of 57.92 ± 5.15 and 51.72 ± 4.63 years, respectively. Among the cardiovascular risk factors, the most prevalent among women with CAD were menopause (84.62%), systemic arterial hypertension (SAH) (69.23%) and sedentary life style (69.23%). Conclusion: We concluded that, in addition to menopause itself, SAH and sedentary lifestyle were the most prevalent cardiovascular risk factors among women with CAD

Avaliação da Função Endotelial em Mulheres Climatéricas com Doença Arterial Coronariana / Evaluation of Endothelial Function in Pre-Menopausal Women With Coronary Arterial Disease

Fundamentos: O endotélio desempenha importante função reguladora vascular. Sua disfunção é um marcador precoce de risco cardiovascular. Entretanto, existem poucos estudos em nosso meio que avaliem a função endotelial em mulheres climatéricas. Objetivo: Avaliar a função endotelial em mulheres climatéricas na presença ou ausência de doença arterial coronariana utilizando-se um método biofísico (espessura médio-intimal das carótidas) e um método bioquímico (níveis séricos de PCR-US). Métodos: Estudo transversal que avaliou o espessamento médio-intimal da artéria carótida e níveis séricos de PCR-US de 31 mulheres climatéricas submetidas a cineangiocoronariografia, no Serviço de Hemodinâmica do Hospital Universitário da Universidade Federal do Maranhão, no período de março de 2012 a julho de 2013. Os dados foram submetidos à análise estatística. Considerou-se um nível de significância de 5%. Resultados:A amostra foi dividida em dois grupos, de acordo com presença de doença arterial coronariana (DAC): grupo com DAC (n = 13) e grupo sem DAC (n = 18). As médias de idades para os grupos foram 57,92 ± 5,17 e 51,72 ± 4,63 anos, respectivamente (p = 0,001). A EMI esteve alterada em 29,03% na população geral. A espessura médio- intimal foi de 1,55 ± 0,78 mm no grupo geral, 1,92 ± 0,94 mm no grupo com DAC e 1,18 ± 0,71 mm no grupo sem DAC (p = 0,001). As pacientes com DAC apresentaram predomínio de alteração da EMI quando comparadas aquelas sem DAC: 36,46% vs. 22,22%, respectivamente. Observou-se uma sensibilidade de 38%, especificidade de 77%, com um valor preditivo positivo de 0,55 e valor preditivo negativo de 0,63 com razão de verossimilhança para teste positivo (likelihood ratio) de 1,73. As pacientes com EMI alterado apresentaram níveis mais elevados de PCR-US, porém sem significância estatística. As pacientes com DAC apresentaram níveis mais elevados de PCR-US, porém sem significância estatística. Conclusão: Na população estudada, a avaliação da função endotelial pelo método da EMI apresentou maior sensibilidade e especificidade para o diagnóstico de DAC quando comparada a mensuração dos níveis de PCR-US em mulheres climatéricas

Background: The endothelium plays an important vascular regulatory function. Its dysfunction is an early marker of cardiovascular risk. However, there are few studies in our community that assess endothelial function in pre-menopausal women. Objective: To assess endothelial function in pre-menopausal women in the presence or absence of coronary artery disease, using a biophysical method (carotid intima media thickness) and a biochemical method (serum levels of hsCRP). Methods: Cross-sectional study that evaluated carotid intima-media thickness and serum levels of hsCRP of 31 pre-menopausal women undergoing coronary angiography at the Hemodynamics Service of Hospital Universitário da Universidade Federal do Maranhão from March 2012 to July 2013. The data were sent to statistical analysis and a statistical significance level of 5% was considered. Results: The sample was divided into two groups according to the presence of coronary artery disease (CAD): CAD group (n = 13) and group without CAD (n = 18). The average ages for the groups were 57.92 ± 5.17 and 51.72 ± 4.63 years, respectively (p = 0.001). CIMT was abnormal in 29.03% in the general population. Carotid intima-media thickness was 1.55 ± 0.78 mm in the general group, 1.92 ± 0.94 mm in the CAD group and 1.18 ± 0.71 mm in the group without CAD (p = 0.001). CAD patients had predominance of abnormal CMIT compared those without CAD: 36.46% vs. 22.22%, respectively. There was a sensitivity of 38%, specificity of 77% with a positive predictive value of 0.55 and a negative predictive value of 0.63 with likelihood ratio of 1.73. Patients with abnormal CIMT presented higher levels of hsCRP, but without statistical significance. CAD patients had higher levels of hsCRP, but without statistical significance. Conclusion: In the population studied, assessment of endothelial function using the CIMT method showed higher sensitivity and specificity for the diagnosis of CAD compared to the measurement of hsCRP levels in menopausal women

Diabetes and cardiovascular events in high-risk patients: Insights from a multicenter registry in a middle-income country

AIMS:The aim of this study was to determine the rate of major clinical events and its determinants in patients with previous cardiovascular event or not, and with or without diabetes from a middle-income country.METHODS:REACT study is a multicenter registry conducted between July 2010 and May 2013 in Brazil. Patients were eligible if they were over 45years old and high cardiovascular risk. Patients were followed for 12months; data were collected regarding adherence to evidence-based therapies and occurrence of clinical events (all-cause mortality, non-fatal cardiac arrest, myocardial infarction, or stroke).

Sex Differences in Mortality After CABG Surgery

ABSTRACT INTRODUCTION: Numerous studies have shown that women undergoing coronary artery bypass graft surgery present higher mortality rate during hospitalization, and often complications when compared to men. OBJECTIVE: To compare the mortality of men and women undergoing coronary artery bypass graft surgery and identify factors related to differences occasionally found. METHODS: Retrospective cohort study conducted with 215 consecutive patients who underwent coronary bypass surgery. RESULTS: Women had a higher average age. Low body surface and dyslipidemia were more prevalent in women (1.65 vs . 1.85, P<0.001: 53% vs . 30%, P =0.001), whereas history of smoking and previous myocardial infarction were more prevalent in men (35% vs .14.7%, P =0.001; 20% vs . 2.7%, P =0.007). Regarding complications in the postoperative period, there was a higher rate of blood transfusions in women. The overall mortality rate was 5.6%, however there was no statistically significant difference in mortality between men and women. It was observed that among the patients who died, the average body surface area was lower than that of patients who did not have this complication. CONCLUSION: There was no difference in mortality between the sexes after coronary artery bypass graft in this service.

Impact of Cardiovascular Interventions on the Quality of Life in the Elderly

ABSTRACT INTRODUCTION: The elderly population is growing rapidly. Political and socio-economic changes led to the demographic transition in this population with the highest number of surgeries and as well as many comorbidities. OBJECTIVE: To evaluate the impact of cardiovascular intervention on quality of life of elderly patients after three and six months. METHODS: Analytical prospective cohort study with elderly between 60 and 80 years of age, of both sexes, with a diagnosis of coronary artery disease and underwent cardiovascular intervention during the period June 2010 to June 2011. Data were collected by individual interviews in the pre and postoperative periods (after three and six months) by telephone. We used the SF-36 to analyse quality of life in order to assess the physical and mental health of the study population. RESULTS: Of the 44 individuals evaluated, 59.1% were men, 75% in the range of 65 to 74 years, 38.6% were white and 38.6% were black, 31.8% were uneducated, 43.2% were married and 68.2% had less than a minimum wage. Prevailed patients: non-diabetics (68.2%), non-obese (81.8%), hypertensive (84.1%), non-alcoholic and non-smokers (68.2% and 61.4%, respectively). A significant increase in the average of the SF-36 scores between pre and post-surgical periods (three and six months) for the domains: functional capacity, pain, general health, vitality and emotional aspect. CONCLUSION: The elderly population undergoing intervention may have cardiovascular benefits and improvements of quality of life. Physical fitness improvement measures can be taken to resume that capability.

Estudo da função endotelial no Brasil: Prevenção de doenças cardiovasculares / Study of endothelial function in Brazil: Cardiovascular prevention

A avaliação da função endotelial permite identificar alterações no endotélio e pode ser avaliada por métodos bioquímicos e biofísicos. Dentre estes, destaca-se a dilatação fluxo-mediada da artéria braquial (DILA) por ser uma técnica ultrassonográfica segura e não invasiva, marcador precoce de doenças cardiovasculares, pois reflete a saúde do endotélio ainda numa fase inicial, ou seja, antes do aparecimento da placa de ateroma. Esta revisão descreve os estudos realizados no Brasil que investigaram a avaliação da função endotelial. A busca dos dados foi realizada em bases da Biblioteca Virtual em Saúde (BIREME) e SciELO. Foram incluídos estudos feitos no Brasil e publicados até agosto 2012, com avaliação da função endotelial por meio da DILA. Dos 16 artigos encontrados, 7 estudos incluíram apenas indivíduos com risco cardiovascular; 8 incluíram indivíduos com e sem risco cardiovascular e somente 1 incluiu indivíduos sem risco cardiovascular. Todos os estudos que avaliaram a função endotelial em indivíduos considerados com risco para doenças cardiovasculares encontraram valores do DILA <10 %. Os estudos sugerem que esse método é confiável na avaliação da função endotelial em indivíduos com ou sem fatores de risco cardiovascular.

Endothelial function assessments help identify alterations to the endothelium and can be evaluated by biochemical and biophysical methods. These include flow-mediated dilation (FMD) of the brachial artery by ultrasonography, a technique that is a safe and non-invasive marker of early cardiovascular disease, indicating the health of the endothelium at an early stage, before the onset of atheroma. This review describes studies conducted in Brazil investigating endothelial function assessments. A search was performed through the databases of the Virtual Health Library (BIREME) and SciELO. Papers on projects conducted in Brazil and published by August 2012 were included in this study, assessing endothelial functions by FMD. Of the sixteen papers found, seven studies included only patients at cardiovascular risk; eight included patients with and without cardiovascular risk and only one included subjects without cardiovascular risk. All the studies evaluating endothelial functions in patients rated as at-risk for cardiovascular disease found FMD values below 10%. These findings suggest that this method is trustworthy for assessing endothelial functions in patients with or without cardiovascular risk factors.

Depression after CABG: a prospective study / Depressão após revascularização do miocárdio: um estudo prospectivo

INTRODUCTION: Depression during or shortly after hospitalization elevated two to three times the risk of mortality or nonfatal cardiac events, significantly increasing the morbidity and mortality of these patients. OBJECTIVE: To assess the impact of revascularization on symptoms of depression in patients with coronary artery disease. METHODS: A prospective cohort study of 57 patients of both sexes undergoing coronary artery bypass grafting between June 2010 and June 2011. We used the SF-36 to assess quality of life, and the Beck Depression Inventory to detect depressive symptoms, applied preoperatively and six months. RESULTS: The prevalence of patients aged 60-69 years was 22 patients (38.60%), 39 men (68.42%), 26 described themselves as mixed race (45.61%), 16 literate (28.07 %) and 30 married (52.63%). The beck depression inventory score demonstrated increased after revascularization: 15 patients mild (26.32%) at time zero to 17 (29.82%) after. And with moderate, seven patients (12.28%) before and 10 (17.54%) after. In the categories of individuals with decreased minimum degree of 32 (56.14%) to 28 (49.12%), and severe of three (5.26%) for two (3.51%) patients. Association was observed between beck depression inventory, gender, age, lifestyle, comorbidities and quality of life. CONCLUSION: There was a high prevalence of elevated beck depression inventory scores, lowest scores of depressive symptoms among men and association between the improvement of quality of life scores and beck depression inventory.

INTRODUÇÃO: A depressão durante ou logo após a hospitalização, eleva duas a três vezes o risco de mortalidade ou eventos cardíacos não-fatais, aumentando sensivelmente a morbimortalidade desses pacientes. OBJETIVO: Avaliar o impacto da revascularização do miocárdio nos sintomas de depressão de pacientes portadores de doença arterial coronariana. MÉTODOS: Estudo de coorte prospectivo de 57 pacientes de ambos os sexos, submetidos à revascularização do miocárdio, entre junho de 2010 e junho de 2011. Foram utilizados os questionários SF-36 para avaliar a qualidade de vida, e o Inventário de Depressão Beck para detectar sintomas depressivos, aplicados no pré-operatório e após seis meses. RESULTADOS: A prevalência de pacientes na faixa etária de 60 a 69 anos foi de 22 (38,60%) pacientes, 39 (68,42%) homens, 26(45,61%) autodeclarados pardos, 16 (28,07%) alfabetizados e 30 (52,63%) casados. O escore Inventário de Depressão Beck demonstrou aumento após a revascularização de 15 (26,32%) pacientes em grau leve no momento zero para 17 (29,82%) após. E com grau moderado, sete (12,28%) pacientes antes e 10 (17,54%) após. Nas categorias de indivíduos com grau mínimo houve redução de 32 (56,14%) para 28 (49,12%) e grave de três (5,26%) para dois (3,51%) pacientes. Observou-se associação entre Inventário de Depressão Beck, sexo, idade, estilo de vida, comorbidades e a qualidade vida. CONCLUSÃO: Observou-se elevada prevalência de escores elevados de inventário de depressão Beck, piores escores de sintomas depressivos entre homens e associação entre a melhoria dos escores de qualidade de vida e o Inventário de Depressão Beck.

Perfil metabólico em mulheres de diferentes índices de massa corporal com síndrome dos ovários policísticos / Metabolic profile in women of different body mass indices with polycystic ovary syndrome

OBJETIVO: Caracterizar e comparar variáveis clínicas, antropométricas e bioquímico-metabólicas de pacientes com síndrome dos ovários policísticos (SOP), estratificadas segundo o índice de massa corpórea (IMC). MÉTODOS: Estudo transversal com 78 mulheres entre 18 e 45 anos com diagnóstico de SOP, pelos Critérios de Rotterdam. As pacientes foram estratificadas segundo o IMC. As variáveis analisadas foram: idade, estado civil, sedentarismo, irregularidade menstrual, pressão arterial (PA), medidas antropométricas, perfil lipídico, glicemia em jejum e dosagens hormonais. Para comparar as variáveis analisadas entre os diferentes IMC, usou-se a Análise de Variância e o Teste de Kruskal-Wallis. O nível de significância para todos os testes foi de 5%. RESULTADOS: As pacientes apresentaram média de idade de 26,3 anos, sendo 79,5% classificadas como sedentárias e 68% com hiperandrogenismo. A circunferência da cintura, a Razão cintura/quadril, a Razão cintura/estatura e a porcentagem de gordura corporal foram maiores no grupo de obesas. A presença de marcadores de risco cardiovascular (RCV - glicemia de jejum, PA sistólica e diastólica e LDL-colesterol) foi diretamente proporcional ao IMC, enquanto que os níveis de HDL-colesterol e SHBG foram inversamente proporcionais ao IMC. CONCLUSÃO: A presença de marcadores de RCV aumentou proporcionalmente ao IMC, evidenciando que o perfil metabólico das mulheres obesas com SOP é mais desfavorável do que n não obesas.

PURPOSE: To characterize and compare clinical, anthropometric and biochemical-metabolic variables in patients with polycystic ovary syndrome (PCOS), stratified according to body mass index (BMI). METHODS: A cross-sectional study conducted on 78 women aged 18 to 45 years with a clinical diagnosis of PCOS by the Rotterdam criteria. Patients were stratified according to BMI. The variables analyzed were: age, marital status, physical inactivity, menstrual irregularity, blood pressure (BP), anthropometric measurements, lipid profile, fasting glucose, and hormone measurements. To compare the variables between the different BMI values we used analysis of variance and the Kruskal-Wallis test. The level of significance was set at 5% for all tests. RESULTS: The patients had a mean age of 26.3 years, 79.5% of them were sedentary and 68% had hyperandrogenism. Waist circumference, waist/hip ratio, waist/height ratio and percentage of body fat were higher in the obese group. The markers of cardiovascular risk (CVR - fasting glucose, systolic and diastolic BP and LDL-cholesterol) were directly proportional to BMI, whereas HDL-cholesterol and SHBG were inversely related to BMI. CONCLUSION: The presence of markers of CVR factors increased proportionally to BMI, indicating that the metabolic profile of obese women with PCOS is more unfavorable than that of non-obese patients.

Angioplastia guiada por ultrassom intracoronariano: metanálise de ensaios clínicos randomizados / Angioplasty guided by intravascular ultrasound: meta-analysis of randomized clinical trials

FUNDAMENTO: O impacto do uso do ultrassom intracoronariano (USIC) na implantação de stents tem resultados inconclusivos. OBJETIVO: Revisão sistemática, com metanálise, do impacto do USIC na implantação de stents quanto à evolução clínica e angiográfica. MÉTODOS: Efetuada busca nas bases Medline/Pubmed, CENTRAL, Embase, Lilacs, Scopus e Web of Science. Incluídos estudos clínicos randomizados (ECR) que avaliaram o implante de stents, orientados pela USIC, comparados com aqueles utilizando a angiografia isoladamente (ANGIO). O intervalo mínimo de acompanhamento foi de seis meses, avaliados os desfechos: trombose, mortalidade, infarto do miocárdio, revascularização percutânea e cirúrgica, eventos cardiovasculares maiores (ECVM) e reestenose. Os desfechos binários foram apresentados considerando o número de eventos em cada grupo; as estimativas foram geradas por um modelo de efeitos aleatórios, considerando a estatística de Mantel-Haenzel como ponderadora e magnitude de efeito ao risco relativo (RR) com seu respectivo intervalo de confiança de 95% (IC 95%). Para quantificação da consistência entre os resultados de cada estudo, utilizou-se o teste de inconsistência I² de Higgins. RESULTADOS: Avaliados 2.689 artigos, incluídos 8 ECR. Houve redução de 27% na reestenose angiográfica (RR: 0,73; IC 95%: 0,54 - 0,97; I² = 51%) e redução estatisticamente significativa nas taxas de revascularizações percutânea e geral (RR: 0,88; IC 95%: 0,51 - 1,53; I² = 61% e RR: 0,73; IC 95%: 0,54 - 0,99; I² = 55%), sem diferença estatística na revascularização cirúrgica (RR: 0,95; IC 95%: 0,52 - 1,74; I² = 0%) em favor do USIC vs. ANGIO. Não foram observadas diferenças nos demais desfechos na comparação entre as duas estratégias. CONCLUSÃO: Angioplastias com implante de stents guiadas por USIC reduzem taxas de reestenose e de revascularizações, não tendo impacto nos desfechos ECVM, infarto agudo do miocárdio, mortalidade ou trombose.

BACKGROUND: The impact of intravascular ultrasound (IVUS) use on stenting has shown inconclusive results. OBJECTIVE: Systematic review and meta-analysis of the impact of IVUS on stenting regarding the clinical and angiographic evolution. METHODS: A search was performed in Medline/Pubmed, CENTRAL, Embase, Lilacs, Scopus and Web of Science databases. It included randomized clinical trials (RCTs) that evaluated the implantation of stents guided by IVUS, compared with those using angiography alone (ANGIO). The minimum follow-up duration was six months and the following outcomes were assessed: thrombosis, mortality, myocardial infarction, percutaneous and surgical revascularization, major adverse cardiovascular events (MACE) and restenosis. The binary outcomes were presented considering the number of events in each group; the estimates were generated by a random effects model, considering Mantel-Haenszel statistics as weighting agent and magnitude of effect for the relative risk (RR) with its respective 95% confidence interval (95%CI). Higgins I² test was used to quantify the consistency between the results of each study. RESULTS: A total of 2,689 articles were evaluated, including 8 RCTs. There was a 27% reduction in angiographic restenosis (RR: 0.73, 95% CI: 0.54-0.97, I² = 51%) and statistically significant reduction in the rates of percutaneous revascularization and overall (RR: 0.88; 95% CI: 0.51 to 1.53, I² = 61%, RR: 0.73, 95% CI: 0.54 to 0.99, I² = 55%), with no statistical difference in surgical revascularization (RR: 0.95, 95% CI: 0.52-1.74, I² = 0%) in favor of IVUS vs. ANGIO. There were no differences regarding the other outcomes in the comparison between the two strategies. CONCLUSION: Angioplasty with stenting guided by IVUS decreases the rates of restenosis and revascularization, with no impact on MACE, acute myocardial infarction, mortality or thrombosis outcomes.
