RESUMO

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.

RESUMO

BACKGROUND: Adhering to a diet adequate in macronutrients is crucial for the secondary prevention of cardiovascular diseases. OBJECTIVE: To assess the prevalence of adherence to recommendations for the consumption of dietary fatty acids for the prevention and treatment of cardiovascular diseases and to estimate whether the presence of certain cardiovascular risk factors would be associated with adherence. METHODS: Cross-sectional study using baseline data from 2,358 participants included in the "Brazilian Cardioprotective Nutritional Program Trial". Dietary intake and cardiovascular risk factors were assessed. Adequate intake of polyunsaturated fatty acids (PUFA) was considered as ≥10% of total daily energy intake; for monounsaturated fatty acids (MUFA), 20%; and for saturated fatty acids (SFA), <7% according to the Brazilian Society of Cardiology. A significance level of 5% was considered in the statistical analysis. RESULTS: No participant adhered to all recommendations simultaneously, and more than half (1,482 [62.9%]) did not adhere to any recommendation. Adherence exclusively to the SFA recommendation was the most prevalent, fulfilled by 659 (28%) participants, followed by adherence exclusively to the PUFA (178 [7.6%]) and MUFA (5 [0.2%]) recommendations. There was no association between the number of comorbidities and adherence to nutritional recommendations (p = 0.269). Participants from the Brazilian Northeast region showed a higher proportion of adherence to SFA consumption recommendations (38.42%) and lower adherence to PUFA intake (3.52%) (p <0.001) compared to other regions. CONCLUSIONS: Among the evaluated sample, there was low adherence to nutritional recommendations for dietary fatty acid consumption.


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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Menopause consists of a physiological process in women between 40 and 50 years of age, and it has substantial consequences for health, ranging from disturbances in lipid and glycidic metabolism to psychological stress and sleep alterations, thereby increasing women's risk of cardiovascular diseases. Here, we attempted to identify potential lipid alterations not identified by the classic methods. METHODS AND RESULTS: We analyzed the serum lipid profile in 40 women in pre- and post-menopause using a lipidomic approach and mass spectrometry. Lipid species presented increased concentrations, with a difference of more than 25% post-menopause and with the ceramides (N.C23:0.Cer, N.C23:0(OH).Cer and N.C24:0(OH).Cer) standing out with a fold change of 1.68, 1.59, and 1.58, respectively. It was also observed that 14 metabolites presented a significant difference in the average concentrations between pre- and post-menopause, especially the ceramide species. Strong and positive correlations were identified between various metabolites and fasting glucose, glycated hemoglobin, total cholesterol, LDL, and triglycerides. Of note were the association ceramide (N.C10:0.Cer) and lysophosphatidylethanolamine (LPE.a.C18:0) between fasting glucose and glycated hemoglobin. CONCLUSION: This study detected lipid alterations, especially in ceramides, post-menopause, as well as correlations with glycidic and lipid markers, which may in the future be useful to investigate diseases associated with menopause.

RESUMO

INTRODUCTION: Among the non-pharmacologic measures for the prevention and treatment of cardiovascular diseases (CVD), which are the first cause of death worldwide, the adequate intake of dietary fibers (DF) has shown an important role. OBJECTIVE: To evaluate the association between the intake of DF and the cardio-metabolic risk factors in individuals on a secondary prevention for CVD. METHODS: Transversal study with basal data of the study's DICA Br participants belonging to collaborative centers in the states of Maranhão (MA), Bahia (BA) and Rio de Janeiro (RJ). Sociodemographic and clinical data were used, as well as the daily intake of DF in individuals of both sexes, with age ≥ 45 years and manifest evidence of arteriosclerosis. The association between the intake of dietary fibers and the cardio-metabolic risk factors was obtained through Poisson's regression model. RESULTS: With 141 evaluated individuals, high frequency of non-appropriateness of DF intake was observed. The participants in the centers of RJ (PR = 0.63; CI 95% = 0.49-0.80) and BA (PR = 0.79; CI 95% = 0.66-0.95), former smokers (PR = 0.59; CI 95% = 0.45-0.78) and non-smokers (PR = 0.62; CI 95% = 0.66-0.95) had fewer chances of having non appropriate intake of DF. On the other hand, overweight individuals showed 28.0% more chances of non-appropriate intake of DF. CONCLUSION: Results showed that the majority of the observed population presented non-appropriate intake of DF and that this low intake was significantly associated with overweight, smoking and location of the collaborative center.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVE: To compare the RIFLE (Risk, Injury, Failure, Loss and End-stage Renal Failure) and AKIN (Acute Kidney Injury Network) criteria for diagnosis of acute kidney injury after coronary artery bypass grafting. METHODS: Retrospective cohort. 169 patients who underwent coronary artery bypass grafting from January 2007 through December 2008 were analyzed. Information was entered into a database and analyzed using STATA 9.0. RESULTS: Patients' mean age was 63.43 1 9.01 years old. Predominantly male patients (66.86%) were studied. Acute Kidney Injury was present in 33.14% by AKIN and in 29.59% by RIFLE. Hemodialysis was required by 3.57% and 4.0% of the patients when AKIN and RIFLE were applied respectively. There was 4.0% and 3.57% mortality of patients with Acute Kidney Injury according to the RIFLE and AKIN criteria, respectively. In 88.76% of the cases, there was good agreement between the two methods in the detection (kappa=0.7380) and stratification (kappa=0.7515) of Acute Kidney Injury. CONCLUSION: This study showed that the RIFLE and AKIN criteria have a good agreement in the detection and stratification of acute kidney injury after coronary artery bypass grafting.

RESUMO

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
