ABSTRACT

Resumo Fundamento Existem dados limitados sobre a evolução clínica de lesões coronarianas não tratadas de acordo com sua gravidade funcional no mundo real. Objetivo Este estudo teve como objetivo avaliar os resultados clínicos de até 5 anos em pacientes com lesões revascularizadas com reserva de fluxo fracionada (FFR) ≤ 0,8 e em pacientes com lesões não revascularizadas com FFR > 0,8. Métodos A avaliação pelo FFR foi realizada em 218 pacientes seguidos por até 5 anos. Os participantes foram classificados com base na FFR no grupo isquêmico (≤ 0,8, grupo intervenção, n = 55), no grupo FFR normal-baixa (> 0,8-0,9, n = 91) e no grupo FFR normal-alta (> 0,9, n = 72). O desfecho primário foram eventos cardíacos adversos maiores (ECAMs), um composto de morte, infarto do miocárdio e necessidade de nova revascularização. O nível de significância adotado neste estudo foi alfa = 0,05; deste modo, resultados com valores de p < 0,05 foram considerados estatisticamente significativos. Resultados A maioria dos participantes era do sexo masculino (62,8%) com média de idade de 64,1 anos. Diabetes estava presente em 27%. À angiografia coronariana, a gravidade da estenose avaliada foi de 62%, 56,4% e 54,3% nos grupos isquêmico, FFR normal-baixa e FFR normal-alta, respectivamente (p < 0,05). O período médio de acompanhamento foi de 3,5 anos. A incidência ECAM foi de 25,5%, 13,2% e 11,1%, respectivamente (p = 0,037). Não houve diferença na incidência de ECAM entre os grupos FFR normal-baixa e FFR normal-alta (p = NS). Conclusão Pacientes com FFR indicativa de isquemia apresentaram piores desfechos quando comparados aos dos grupos não isquêmicos. Entre os grupos que apresentaram valores de FFR considerados normal-baixo e normal-alto, não houve diferença na incidência de eventos. Há necessidade de estudos de longo prazo e com grande número de pacientes para melhor avaliar os desfechos cardiovasculares em pacientes portadores de estenose coronariana moderada com valores de FFR entre 0,8 e 1,0.


Abstract Background There are limited real-world data on the clinical course of untreated coronary lesions according to their functional severity. Objective To evaluate the 5-year clinical outcomes of patients with revascularized lesions with fractional flow reserve (FFR) ≤ 0.8 and patients with non-revascularized lesions with FFR > 0.8. Methods The FFR assessment was performed in 218 patients followed for up to 5 years. Participants were classified based on FFR into ischemia group (≤ 0.8, intervention group, n = 55), low-normal FFR group (> 0.8-0.9, n = 91), and high-normal FFR group (> 0.9, n = 72). The primary endpoint was major adverse cardiac events (MACEs), a composite of death, myocardial infarction, and need for repeat revascularization. The significance level was set at 0.05; therefore, results with a p-value < 0.05 were considered statistically significant. Results Most patients were male (62.8%) with a mean age of 64.1 years. Diabetes was present in 27%. On coronary angiography, the severity of stenosis was 62% in the ischemia group, 56.4% in the low-normal FFR group, and 54.3% in the high-normal FFR group (p<0.05). Mean follow-up was 3.5 years. The incidence of MACEs was 25.5%, 13.2%, and 11.1%, respectively (p=0.037). MACE incidence did not differ significantly between the low-normal and high-normal FFR groups. Conclusion Patients with FFR indicative of ischemia had poorer outcomes than those in non-ischemia groups. There was no difference in the incidence of events between the low-normal and high-normal FFR groups. Long-term studies with a large sample size are needed to better assess cardiovascular outcomes in patients with moderate coronary stenosis with FFR values between 0.8 and 1.0.

ABSTRACT

Resumo Os limites da fração de ejeção do ventrículo esquerdo (FEVE) para a insuficiência cardíaca (IC) com FEVE levemente reduzida (ICFElr) têm sido questionados, já que evidências demonstram que alguns medicamentos utilizados para IC com FEVE <40% (ICFEr) demonstram eficácia também em populações com FEVE < 60%. Objetivo do estudo foi comparar a sobrevida total e cardiovascular de pacientes com IC com FEVE 40-59% com paciente com ICFEr e IC com FEVE ≥ 60%. Foram incluídos pacientes com IC descompensada que preencheram os critérios diagnósticos de Framingham na admissão hospitalar entre 2009 e 2011. Os pacientes foram divididos em ICFEr, IC com FEVE 40-59% e IC com FEVE ≥ 60%. O método de Kaplan-Meier foi usado para detectar a sobrevida geral e cardiovascular em 10 anos. A significância estatística foi estabelecida em p <0,05. Foram incluídos 400 pacientes, com idade média de 69 ± 14 anos. A sobrevida cardiovascular nos pacientes com IC e FEVE 40-59% não foi diferente em comparação aos pacientes com ICFEr [Hazard Ratio (HR) ajustado 0,86 - Intervalo de Confiança (IC) 95% 0,61-1,22; Ptrend = NS], mas foi estatisticamente diferente em comparação aos com FEVE ≥ 60% (HR ajustado = 0,64 - IC95% 0,44-0,94; Ptrend = 0,023). Não houve diferença na taxa de sobrevida de 10 anos entre diferentes grupos de FEVE. O grupo de pacientes com IC e FEVE ≥ 60% teve maior sobrevida cardiovascular que os outros grupos.


Abstract Definitions of left ventricular ejection fraction (LVEF) cut-off values for HF with mildly reduced LVEF (HFmrEF) have been a subject of debate, in the face of evidence that some drugs used in the treatment of HF with LFEV < 40% (HFrEF) are also effective in patients with LVEF < 60%. The aim of this study was to compare overall survival and cardiovascular survival in HF patients with LVEF of 40-59% in patients with HFrEF and HF with LVEF ≥ 60%. Patients with decompensated HF who met the Framingham diagnostic criteria at hospital admission between 2009 and 2011 were included. Patients were divided into HFrEF, HF with LVEF 40-59%, and HF with LVEF ≥ 60%. The Kaplan-Meier was used to determine ten-year overall survival and cardiovascular survival. The statistical significance was established at p<0.05. A total of 400 patients were included, with a mean age of 69 ± 14 years. Cardiovascular survival in patients with HF and LVEF of 40-59% was not significantly different than in patients with HFrEF (adjusted Hazard Ratio [HR] 0.86; 95% Confidence Interval [CI] 0.61-1.22, Ptrend = NS), but was statistically different compared with patients with LVEF ≥ 60% (adjusted HR of 0.64; 95% CI 0.44-0.94, Ptrend = 0.023). No difference was found in 10-year survival between the LVEF groups. Patients with HF and LVEF ≥ 60% had significantly higher cardiovascular survival compared with the other groups.

ABSTRACT

ABSTRACT Introduction: Due to Brazilian population aging, prevalence of aortic stenosis, and limited number of scores in literature, it is essential to develop risk scores adapted to our reality and created in the specific context of this disease. Methods: This is an observational historical cohort study with analysis of 802 aortic stenosis patients who underwent valve replacement at Hospital São Lucas, Pontifícia Universidade Católica do Rio Grande do Sul, from 1996 to 2018. With the aid of logistic regression, a weighted risk score was constructed based on the magnitude of the coeficients β of the logistic equation. Two performance statistics were obtained: area under the receiver operating characteristic curve and the chi-square (χ2) of Hosmer-Lemeshow goodness-of-fit with Pearson's correlation coeficient between the observed events and predicted as a model calibration estimate. Results: The risk predictors that composed the score were valve replacement surgery combined with coronary artery bypass grafting, prior renal failure, New York Heart Association class III/IV heart failure, age > 70 years, and ejection fraction < 50%. The receiver operating characteristic curve area was 0.77 (95% confidence interval: 0.72-0.82); regarding the model calibration estimated between observed/predicted mortality, Hosmer-Lemeshow test χ2 = 3,70 (P=0.594) and Pearson's coeficient r = 0.98 (P<0.001). Conclusion: We propose the creation of a simple score, adapted to the Brazilian reality, with good performance and which can be validated in other institutions.

ABSTRACT

Abstract Introduction: Stroke is a complication that causes considerable morbidity and mortality during the heart surgery postoperative period (incidence: 1.3 to 5%; mortality: 13 to 41%). Models for assessing the risk of stroke after heart surgery have been proposed, but most of them do not evaluate postoperative morbidity. The aim of this study was to develop a risk score for postoperative stroke in patients who undergo heart surgery with cardiopulmonary bypass. Methods: A cohort study was conducted with data from 4,862 patients who underwent surgery from 1996 to 2016. Logistic regression was used to assess relationships between risk factors and stroke. Data from 3,258 patients were used to construct the model. The model's performance was then validated using data from the remainder of the patients (n=1,604). The model's accuracy was tested using the area under the receiver operating characteristic (ROC) curve. Results: The prevalence of stroke during the postoperative period was 3% (n=149); 59% of the patients who exhibited this outcome were male, 51% were aged ≥ 66 years, and 31.5% of the patients died. The variables that remained as independent predictors of the outcome after multivariate analysis were advanced age, urgent/emergency surgery, peripheral arterial occlusive disease, history of cerebrovascular disease, and cardiopulmonary bypass time ≥ 110 minutes. The area under the ROC curve was 0.71 (95% confidence interval 0.66 - 0.75). Conclusion: We were able to develop a risk score for stroke after heart surgery. This score classifies patients as low, medium, high, or very high risk of a surgery-related stroke.

ABSTRACT

Abstract The association between periodontitis and myocardial infarction remains unclear in the literature. Few studies have addressed periodontitis exposure as a predisposing factor for the development of myocardial infarction. Therefore, the present systematic review aims to analyze the association between periodontitis and myocardial infarction. This meta-analysis systematically searched MEDLINE, EMBASE, The Cochrane Controlled Trials Register, SCIELO, LILACS, CINAHL, Scopus, Web of Science and grey literature for studies estimating the association between periodontitis and myocardial infarction. Quality of evidence was assessed for all studies. The meta-analysis was conducted using random-effects models. Four of the six studies selected were included in the meta-analysis, including 1,035,703 subjects. The association between periodontitis and myocardial infarction was: RR: 5.99 (95% CI: 1.17-30.68), but with high heterogeneity (I2 = 100%; p <0.01). The results including only the highest quality articles, was lower: RR: 2.62 (95% CI: 1.47-4.70 3.83), but with lower heterogeneity (I2 = 85.5%; p < 0.01).The present systematic review with meta-analysis showed an association between periodontitis and acute myocardial infarction, but with a high level of heterogeneity.

ABSTRACT

Abstract Background Prolonged mechanical ventilation (MV) after cardiac surgery imposes a significant burden on the patient in terms of morbidity and financial hospital costs. Objective To develop a risk score model to predict prolonged MV in patients undergoing coronary artery bypass grafting (CABG) surgery. Methods This was a historical cohort study of 4165 adult patients undergoing CABG between January 1996 and December 2016. MV for periods ≥ 12 hours was considered prolonged. Logistic regression was used to examine the relationship between risk predictors and prolonged MV. The variables were scored according to the odds ratio. To build the risk score, the database was randomly divided into 2 parts: development data set (2/3) with 2746 patients and internal validation data set (1/3) with 1419 patients. The final score was validated in the total database and the model's accuracy was tested by performance statistics. Significance was established at p < 0.05. Results Prolonged MV was observed in 783 (18.8%) patients. Predictors of risk were age ≥ 65 years, urgent/emergency surgery, body mass index ≥ 30 kg/m2, chronic kidney disease, chronic obstructive pulmonary disease, and cardiopulmonary bypass time ≥ 120 minutes. The area under the ROC curve was 0.66 (95% CI, 0.64-0.68; p<0.001), the Hosmer-Lemeshow chi-square test was χ2: 3.38 (p=0.642), and Pearson's correlation was r = 0.99 (p<0.001), indicating the model's satisfactory ability to predict the occurrence of prolonged MV. Conclusion Selected variables allowed the construction of a simplified risk score for daily practice, which may classify the patients as having low, moderate, high, and very high risk.

ABSTRACT

Resumo Fundamento Na prática clínica, há evidências de falhas na prescrição de terapias baseadas em evidências para pacientes de alto risco cardiovascular. Entretanto, no Brasil, ainda são insuficientes os dados sobre a evolução ao longo de 1 ano desses pacientes. Objetivos Descrição no acompanhamento de 12 meses da utilização de terapias baseadas em evidência e da ocorrência de desfechos cardiovasculares maiores e seus principais preditores em um registro brasileiro multicêntrico de pacientes de alto risco cardiovascular. Métodos Estudo observacional prospectivo que documentou a prática clínica ambulatorial de indivíduos acima de 45 anos e de alto risco cardiovascular tanto em prevenção primária como secundária. Os pacientes foram seguidos por 1 ano e avaliou-se a prescrição de terapias baseadas em evidência e a ocorrência de eventos cardiovasculares maiores (infarto agudo do miocárdio [IAM], acidente vascular cerebral [AVC], parada cardíaca e mortalidade por causa cardiovascular). Valores de p < 0,05 foram considerados estatisticamente significantes. Resultados De julho de 2010 até agosto de 2014, 5.076 indivíduos foram incluídos em 48 centros, sendo 91% dos 4.975 pacientes elegíveis acompanhados em centros de cardiologia e 68,6% em prevenção secundária. Em 1 ano, o uso concomitante de antiplaquetários, estatinas e inibidores da enzima conversora de angiotensina (IECA) reduziu de 28,3% para 24,2% (valor de p < 0,001). A taxa de eventos cardiovasculares maiores foi de 5,46%, e os preditores identificados foram: idade, pacientes em prevenção secundária e nefropatia diabética. Conclusões Neste grande registro nacional de pacientes de alto risco cardiovascular, foram identificados preditores de risco semelhantes aos registros internacionais, porém a adesão da prescrição médica a terapias baseadas em evidência esteve abaixo dos dados da literatura internacional e apresentou piora significativa em 1 ano.

Abstract Background In clinical practice, there is evidence of failure to prescribe evidence-based therapies for patients at high cardiovascular risk. However, in Brazil, data on 1-year outcomes of these patients remain insufficient. Objectives To describe the use of evidence-based therapies and the occurrence of major cardiovascular outcomes and their major predictors in a 12-month follow-up of a Brazilian multicenter registry of patients at high cardiovascular risk. Methods This prospective observational study documented the outpatient clinical practice of managing patients over 45 years of age and of high cardiovascular risk in both primary and secondary prevention. Patients were followed-up for 1 year, and the prescription of evidence-based therapies and the occurrence of major cardiovascular events (myocardial infarction, stroke, cardiac arrest, and cardiovascular death) were assessed. P-values < 0.05 were considered statistically significant. Results From July 2010 to August 2014, a total of 5076 individuals were enrolled in 48 centers, 91% of the 4975 eligible patients were followed-up in cardiology centers, and 68.6% were in secondary prevention. At 1 year, the concomitant use of antiplatelet agents, statins, and angiotensin-converting enzyme inhibitors reduced from 28.3% to 24.2% (p < 0.001). Major cardiovascular event rate was 5.46%, and the identified predictors were age, patients in secondary prevention, and diabetic nephropathy. Conclusions In this large national registry of patients at high cardiovascular risk, risk predictors similar to those of international registries were identified, but medical prescription adherence to evidence-based therapies was inferior and significantly worsened at 1 year.

ABSTRACT

Resumo Fundamento A insuficiência cardíaca (IC) com fração de ejeção na faixa média ou intermediária (ICFEI) (em inglês, "mid-range ejection fraction) foi recentemente descrita em diretrizes europeia e brasileira recentes sobre o manejo da insuficiência cardíaca (IC). A fração de ejeção (FE) é um parâmetro importante para direcionar terapia e prognóstico. Estudos têm mostrado resultados conflitantes sem dados representativos de países em desenvolvimento. Objetivo Analisar e comparar a taxa de sobrevida em pacientes com ICFEI com pacientes com IC e FE reduzida (ICFEr), e pacientes com IC e FE preservada, e avaliar as características clínicas desses pacientes. Métodos Estudo coorte que incluiu pacientes com IC aguda admitidos no departamento de emergência de um hospital terciário, referência em cardiologia, localizado no sul do Brasil, entre 2009 e 2011. A amostra foi dividida em três grupos de acordo com a FE: reduzida, intermediária e preservada. Curva de Kaplan-Meier foi analisada de acordo com a FE, e uma análise de regressão logística foi realizada. A significância estatística foi estabelecida em p<0,05. Resultados Um total de 380 pacientes foram analisados. A maioria dos pacientes apresentaram ICFEp (515), seguido de ICFEr (32%) e ICFEI (17%). Os pacientes com ICFEI apresentaram características intermediárias em relação à idade, pressão arterial, e diâmetros ventriculares, e a maioria era de etiologia isquêmica. O período mediano de acompanhamento foi de 4 anos. Não se observou diferença na sobrevida geral ou na mortalidade cardiovascular (p=0,03) entre os grupos de FE (FE reduzida: mortalidade de 40,5%; FE intermediária: 39,7%, e FE preservada 26%). A mortalidade hospitalar foi 7,6%. Conclusão Não houve diferença na taxa de sobrevida entre os grupos de FE diferentes. Os pacientes com ICFEI apresentaram maior mortalidade por doenças cardiovasculares em comparação a pacientes com ICFEp. (Arq Bras Cardiol. 2021; 116(1):14-23)


Abstract Background Heart Failure with mid-range Ejection Fraction (HFmEF) was recently described by European and Brazilian guidelines on Heart Failure (HF). The ejection fraction (EF) is an important parameter to guide therapy and prognosis. Studies have shown conflicting results without representative data from developing countries. Objective To analyze and compare survival rate in patients with HFmEF, HF patients with reduced EF (HFrEF), and HF patients with preserved EF (HFpEF), and to evaluate the clinical characteristics of these patients. Methods A cohort study that included adult patients with acute HF admitted through the emergency department to a tertiary hospital, reference in cardiology, in south Brazil from 2009 to 2011. The sample was divided into three groups according to EF: reduced, mid-range and preserved. A Kaplan-Meier curve was analyzed according to the EF, and a logistic regression analysis was done. Statistical significance was established as p < 0.05. Results A total of 380 patients were analyzed. Most patients had HFpEF (51%), followed by patients with HFrEF (32%) and HFmEF (17%). Patients with HFmEF showed intermediate characteristics related to age, blood pressure and ventricular diameters, and most patients were of ischemic etiology. Median follow-up time was 4.0 years. There was no statistical difference in overall survival or cardiovascular mortality (p=.0031) between the EF groups (reduced EF: 40.5% mortality; mid-range EF 39.7% and preserved EF 26%). Hospital mortality was 7.6%. Conclusion There was no difference in overall survival rate between the EF groups. Patients with HFmEF showed higher mortality from cardiovascular diseases in comparison with HFpEF patients. (Arq Bras Cardiol. 2021; 116(1):14-23)

ABSTRACT

Abstract Background: Lifestyle intervention programs can reduce the prevalence of metabolic syndrome (MetS) and, therefore, reduce the risk for cardiac disease, one of the main public health problems nowadays. Objective: The aim of this study was to compare the effects of three types of approach for lifestyle change programs in the reduction of metabolic parameters, and to identify its impact on the quality of life (QOL) of individuals with MetS. Methods: A randomized controlled trial included 72 individuals with MetS aged 30-59 years. Individuals were randomized into three groups of multidisciplinary intervention [Standard Intervention (SI) - control group; Group Intervention (GI); and Individual Intervention (II)] during 12 weeks. The primary outcome was change in the metabolic parameters, and secondarily, the improvement in QOL measures at three moments: baseline, 3 and 9 months. Results: Group and individual interventions resulted in a significant reduction in body mass index, waist circumference, systolic blood pressure at 3 months and the improvement of QOL, although it was significantly associated with the physical functioning domain. However, these changes did not remain 6 months after the end of intervention. Depression and anxiety were significantly associated with worse QOL, although they showed no effect on the response to intervention. Conclusion: Multidisciplinary intervention, especially in a group, might be an effective and economically feasible strategy in the control of metabolic parameters of MetS and improvement of QOL compared to SI, even in a dose-effect relationship.


Resumo Fundamento: Programas de intervenção em estilo de vida podem reduzir a prevalência de síndrome metabólica (SM) e, portanto, diminuir o risco de doença cardíaca, um dos principais problemas de saúde pública da atualidade. Objetivo: Comparar os efeitos de três tipos de abordagem para programas de mudança no estilo de vida visando à redução dos parâmetros metabólicos, assim como identificar seu impacto na qualidade de vida (QV) de indivíduos com SM. Métodos: Estudo randomizado controlado incluindo 72 indivíduos com SM com idade de 30 a 59 anos, que foram randomizados em três grupos de intervenção multidisciplinar [Intervenção Padrão (IP) - grupo controle; Intervenção em Grupo (IG); e Intervenção Individual (II)] por 12 semanas. O desfecho primário foi a mudança nos parâmetros metabólicos, e o secundário, a melhora nas medidas de QV em três momentos: condição basal, aos 3 e aos 9 meses. Resultados: As intervenções IG e II resultaram em uma significativa redução em índice de massa corporal, circunferência abdominal e pressão arterial sistólica, e em melhoras da QV aos 3 meses, embora significativamente associadas com o domínio 'capacidade funcional'. Tais mudanças, entretanto, não permaneceram 6 meses após o final da intervenção. Depressão e ansiedade associaram-se significativamente com pior QV, embora sem efeito na resposta à intervenção. Conclusão: A intervenção multidisciplinar, em especial em grupo, pode ser uma estratégia efetiva e economicamente possível para controlar os parâmetros metabólicos de SM e melhorar a QV quando comparada à IP, mesmo em uma relação de dose-efeito.

ABSTRACT

AIMS: Despite all progress made in understanding and treating metabolic syndrome, the study of its impact on quality of life is still controversial and not well understood. The aim of this study was to test the hypothesis that metabolic syndrome can be associated with a worse quality of life. MESTHODS: A controlled cross-sectional study included individuals with metabolic syndrome, from the sub-analysis of a randomized clinical trial about lifestyle modification and cardiovascular risk factors, as well as individuals with no metabolic syndrome, attended as outpatients in several clinics at a general university hospital in Southern Brazil. Measurements were made in individual interviews and included data collection, laboratory tests, and application of general scales such as Mini-Mental State Examination and Medical Outcomes Study Short Form, General Health Survey (SF-36). Comparisons of quantitative data used the Student's t test, followed by analysis of covariance or multiple linear regression for adjustment, and correlation coefficient. For categorical data, the Chi-square or Fisher's exact test were used. RESULTS: The study included 229 individuals, 118 metabolic syndrome and 111 no metabolic syndrome. In univariate analysis, metabolic syndrome was significantly associated with lower scores in the social functioning (p<0.001) and role emotional (p=0.019) quality of life domains, and with the Mental Component Summary score of the SF-36 (p=0.013). However, after adjustments for confounding factors, especially body mass index, the significance of these associations was lost. The only significant association between metabolic syndrome and quality of life that has remained after the adjustments was with worse QOL in the role emotional domain, but only in men (p=0.049). CONCLUSIONS: After adjusting for multiple variables, metabolic syndrome was significantly associated with decreased quality of life scores in men in the role emotional domain.


OBJETIVOS: Apesar dos avanços no entendimento e tratamento da síndrome metabólica, o estudo do seu impacto sobre a qualidade de vida é ainda controverso e inconclusivo. O objetivo deste estudo foi testar a hipótese de que a síndrome metabólica estaria associada à piora da qualidade de vida. MÉTODOS: Um estudo transversal controlado incluiu indivíduos com síndrome metabólica, advindos da subanálise de um estudo controlado randomizado sobre modificação de estilo de vida e fatores de risco cardiovascular; e indivíduos sem síndrome metabólica, provenientes de diversos ambulatórios de um hospital geral no sul do Brasil. As medidas foram realizadas em entrevistas individuais, que incluíram coleta de dados demográficos, testes laboratoriais e aplicação do Exame do Estado Mental e o Medical Outcome Study Short Form, General Health Survey (SF-36). Para comparações entre dados quantitativos, foram utilizados teste t de Student, análise de covariância ou regressão linear múltipla para os ajustes dos fatores confundidores, e coeficiente de correlação. Para dados categóricos foi utilizado o qui quadrado ou o Exato de Fisher quando necessário. RESULTADOS: O estudo incluiu 229 indivíduos, sendo 118 com síndrome metabólica e 111 sem síndrome metabólica. A síndrome metabólica foi significativamente associada com baixos escores de qualidade de vida nos domínios funcionamento social (p<0,001) e aspectos emocionais (p=0,019); e com baixos escores no Componente Sumário da Saúde Mental do SF-36 (p=0,013). Entretanto, após ajustes para os fatores confundidores, especialmente índice de massa corporal, a significância dessas associações foi perdida. A única associação significativa que foi mantida entre síndrome metabólica e qualidade de vida após a análise ajustada foi com o domínio aspectos emocionais, embora somente em homens (p=0,049). CONCLUSÕES: Após o ajuste para múltiplas variáveis, a síndrome metabólica foi significativamente associada com diminuição da pontuação para qualidade de vida em homens, no domínio aspectos emocionais.

ABSTRACT

OBJETIVOS: Avaliar o perfil lipídico e parâmetros inflamatórios de pacientes com doença de Crohn e retocolite ulcerativa, e correlacionar com os níveis de atividade das doenças. MÉTODOS: Estudo transversal com pacientes acompanhados no Ambulatório de Doença Inflamatória Intestinal do Hospital São Lucas da PUCRS. Foram avaliadas as características demográficas, antropométricas e metabólicas dos pacientes com doença inflamatória intestinal crônica. Avaliaram-se parâmetros lipídios e inflamatórios e analisou-se a correlação entre a gravidade da doença inflamatória e os parâmetros metabólicos, na doença de Crohn pelo índice de Harvey-Bradshaw e na retocolite ulcerativa pelo método de Truelove e Witts. RESULTADOS: Participaram do estudo 122 pacientes de ambos os sexos com doença inflamatória intestinal, estratificados em: doença de Crohn (n=64) e retocolite ulcerativa (n=58). As mulheres representaram 54,1% da amostra, a média de idade foi de 41,6±12,6 anos e a média de índice de massa corporal foi de 25 ± 4,4kg/m2 . O colesterol ligado à lipoproteína de baixa densidade (LDL-c) mostrou-se significativamente mais elevado nos pacientes com retocolite ulcerativa comparando-se aos pacientes com doença de Crohn (p=0,006). A proteína C reativa aumentada esteve associada com maior gravidade do processo inflamatório em pacientes com doença de Crohn (p=0,027), quando analisada pelo índice de Harvey-Bradshaw. Na retocolite ulcerativa, conforme o índice de Truelove e Witts, houve correlação fraca entre atividade da doença e colesterol ligado à lipoproteína de alta densidade (HDL-c) (rs =-0,29; p=0,036) e entre atividade da doença e colesterol total (rs =-0,30; p=0,028). Cerca de dois terços dos pacientes (67,6%) apresentaram o HDL-c abaixo dos valores recomendados. CONCLUSÕES: O LDL-c mostrou-se significativamente mais elevado nos pacientes com retocolite ulcerativa comparados aos pacientes com doença de Crohn. O HDL-c apresentou níveis reduzidos em pacientes com doença inflamatória mais grave na retocolite ulcerativa. A proteína C reativa aumentada em pacientes com doença de Crohn esteve associada com a gravidade do processo inflamatório determinada pelo índice de Harvey-Bradshaw. A detecção dessas alterações metabólicas pode auxiliar na identificação de indivíduos com potencial risco para eventos cardiovasculares.


AIMS: To evaluate the lipid profile and inflammatory parameters in patients with Crohn's disease (CD), and ulcerative colitis (UC) and correlate them with disease activity levels. METHODS: Cross-sectional study of patients followed up at the Inflammatory Bowel Disease Outpatient Clinic of São Lucas Hospital at Pontifícia Universidade Católica do Rio Grande do Sul, Brazil. The demographic, anthropometric, and metabolic characteristics of patients with chronic inflammatory disease were evaluated. Lipids and inflammatory parameters were evaluated as well as the correlation between the severity of inflammatory disease and metabolic parameters using the Harvey-Bradshaw index for CD and Truelove and Witts' method for UC. RESULTS: The study included 122 male and female patients with inflammatory bowel disease classified into CD (n=64) and UC (n=58). Women accounted for 54.1% of the sample, with a mean age of 41.6±12.6 years and a BMI of 25±4.4kg/m2 . Low-density lipoprotein cholesterol (LDL-c) was significantly higher in UC than in CD (p=0.006). Higher C-reactive protein levels were associated with a more severe inflammatory process in CD patients (p=0.027) according to the Harvey-Bradshaw index. In UC, there was a weak correlation between disease activity and high-density lipoprotein cholesterol (HDL-c) (rs =-0.29; p=0.036) and between disease activity and total cholesterol (rs =-0.30; p=0.028) according to Truelove and Witts' index. The HDL-c of about two thirds of the patients (67.6%) was below the recommended values. CONCLUSIONS: LDL-c was significantly higher in patients with UC than in those with CD. HDL-c was lower in patients with more severe inflammatory disease triggered by UC. Increased C-reactive protein levels in CD patients were associated with severity of the inflammatory process determined by the Harvey-Bradshaw index. The detection of these metabolic changes may help identify individuals with potential risk for cardiovascular events.

ABSTRACT

O infarto agudo do miocárdio apresenta incidência crescente no mundo nos últimos anos. A isquemia aguda do miocárdio pode levar a necrose miocárdica e a complicações sistêmicas, até mesmo a morte. O adequado manejo dos pacientes com suspeita de infarto baseia-se na tentativa de reestabelecer o fluxo sanguíneo ao tecido isquêmico, visando interromper o mecanismo de lesão. Ao médico emergencista cabe o total domínio dos algoritmos indicados no caso de IAM, visando a abordagem precoce do paciente e redução de desfechos cardiovasculares.


Myocardial infarction's incidence has been presenting an increasing worldwide in the last years. Acute myocardial ischemia can lead to myocardial necrosis and systemic complications, even death. The adequate management of patients suspected of infarction is based in trying to reestablish the blood flow to the ischemic tissue, owing to interrupt the mechanism of lesion. It is the emergency physician responsibility to have total domain of the myocardial infarction algorithms, looking forward to a quick patient approach and to minimize cardiovascular events.

ABSTRACT

ABSTRACT Objectives: to present currently available evidence to verify the association between metabolic syndrome and quality of life. Method: Cochrane Library, EMBASE, Medline and LILACS databases were studied for all studies investigating the association with metabolic syndrome and quality of life. Two blinded reviewers extracted data and one more was chosen in case of doubt. Results: a total of 30 studies were included, considering inclusion and exclusion criteria, which involved 62.063 patients. Almost all studies suggested that metabolic syndrome is significantly associated with impaired quality of life. Some, however, found association only in women, or only if associated with depression or Body Mass Index. Merely one study did not find association after adjusted for confounding factors. Conclusion: although there are a few studies available about the relationship between metabolic syndrome and quality of life, a growing body of evidence has shown significant association between metabolic syndrome and the worsening of quality of life. However, it is necessary to carry out further longitudinal studies to confirm this association and verify whether this relationship is linear, or only an association factor.


RESUMO Objetivos: apresentar as evidências disponíveis atuais para verificar a associação entre síndrome metabólica e qualidade de vida. Métodos: Cochrane Library, EMBASE, Medline e LILACS foram as bases de dados consultadas na identificação de todos os estudos que investigavam a associação entre síndrome metabólica e qualidade de vida. Dois revisores de forma independente e cegados extraíram os dados e, em caso de dúvidas, um outro revisor foi escolhido. Resultados: um total de 30 estudos foram incluídos, considerando os critérios de inclusão e exclusão, os quais envolveram 62.063 pacientes. A maioria dos estudos sugerem que a síndrome metabólica é significativamente associada à piora da qualidade de vida. Alguns, no entanto, demonstram associação apenas em mulheres, ou somente se associadas à depressão ou índice de massa corporal. Entretanto, um estudo não demonstrou tal associação, após ajuste para os fatores confundidores. Conclusão: apesar de dispormos de poucos estudos a respeito da relação entre síndrome metabólica e qualidade de vida, um número crescente de evidências tem demonstrado uma significativa associação entre a síndrome metabólica e o prejuízo na qualidade de vida. Entretanto, é necessário que sejam conduzidos estudos longitudinais com objetivo de confirmar esta associação e, determinar se esta relação é linear ou somente um fator de associação.


RESUMEN Objetivo: presentar las evidencias actualmente disponibles para verificar la asociación entre el síndrome metabólico y la calidad de vida. Métodos: se consultaron las bases de datos Cochrane Library, EMBASE, Medline y LILACS para la identificación de todos los estudios que investigaban la asociación entre síndrome metabólico y calidad de vida. Dos revisores de tipo ciego extrajeron los datos y en caso de dudas se eligió un revisor adicional. Resultados: un total de 30 estudios fueron incluidos, llevando en consideración los criterios de inclusión y exclusión, totalizando 62.063 pacientes. La mayoría de los estudios sugieren que el síndrome metabólico esta significativamente asociado al empeoramiento de la calidad de vida. Algunos, sin embargo muestran asociación solamente en mujeres, o sólo asociados a depresión o índice de masa corporal. También un estudio no mostró esta asociación después de ajustar por los factores confundentes. Conclusión: a pesar de tener a disposición pocos estudios en referencia a la relación entre síndrome metabólico y calidad de vida, un número creciente de evidencias ha demostrado una asociación significativa entre síndrome metabólico y perjuicio de la calidad de vida. Sin embargo es necesario que se realicen estudios longitudinales con el objetivo de confirmar esta asociación y determinar si esta relación es linear o solamente un factor de asociación.

ABSTRACT

Fundamentos: A doença cardiovascular (DCV) é a principal causa de morte nos países em desenvolvimento. Os indivíduos com síndrome metabólica (SM) apresentam risco elevado para DCV. Os fatores de risco tradicionais em conjunto, não explicam todos os eventos cardiovasculares. O fator von Willebrand (FvW), envolvido na agregação plaquetária e trombose, tem sido investigado nesse contexto. Objetivo: Investigar a relação entre FvW e DCV, em pacientes portadores de SM, com e sem eventos cardiovasculares prévios. Métodos: Estudados 77 pacientes ambulatoriais, ≥18 anos, portadores de SM de acordo com os critérios estabelecidos pela NCEP-ATP III. Mediu-se o nível plasmático do FvW e comparou-se os valores médios entre os grupos com DCV prévia (n=30) e sem DCV documentada (n=47). Resultados: Da população estudada, 66,0% eram do sexo feminino, 78,0% de etnia branca, média de idade 63,7±8,9 anos, peso médio 82,9±14,9 kg e índice de massa corpórea 32,2±4,8 kg/m2. O nível plasmático médio do FvW foi similar nos pacientes com e sem DCV prévia, com valores de 154,5±52,1 e 155,47±41,4, respectivamente. Observou-se associação entre o diabetes mellitus (DM) e DCV estabelecida, que permaneceu significativa após ajuste para as demais variáveis incluídas no modelo multivariado. Conclusões: Não houve diferença no nível plasmático médio do FvW entre os pacientes portadores de SM, com e sem DCV documentada. A presença de DM, entretanto, esteve associada de forma independente com DCV nesta população.


Background: Cardiovascular disease (CVD) is the leading cause of death in developing countries. Individuals with metabolic syndrome (MS) are at increased risk for CVD. The traditional risk factors, altogether, do not explain all cardiovascular events. The von Willebrand factor (vWF), involved in platelet aggregation and thrombosis, has been investigated in this context. Objective: To investigate the relationship between the vWF and CVD in patients with MS, with and without previous cardiovascular events. Methods: The study included 77 outpatients, ≥18 years, with MS, according to the criteria established by NCEP-ATP III. The plasma level of vWF was measured and the mean values were compared between the groups with prior CVD (n=30) and without documented CVD (n=47). Results: In the study population, 66.0% were female, 78.0% were white, mean age 63.7±8.9, mean weight 82.9±14.9 kg, and body mass index 32.2±4.8 kg/m2. The average plasma level of vWF was similar in patients with and without previous CVD, with values of 154.5±52.1 and 155.47±41.4, respectively. There was an association between diabetes mellitus (DM) and established CVD, which remained significant after adjusting for other variables included in the multivariate model. Conclusions: There was no difference in the mean plasma level of vWF among patients with MS, with and without documented CVD. The presence of DM, however, was independently associated with CVD in this population.

ABSTRACT

Metabolic Syndrome is a complex clinical condition that brings together a set of cardiovascular risk factors. Lifestyle changes, such as eating habit improvements, are first-choice therapies for the treatment of this clinical condition. This study aimed to evaluate the effect of short-term nutritional counseling, on the diet quality and total energetic value (TEV) in individuals with Metabolic Syndrome. Eighty subjects (men and women) aged 30 to 60 years with metabolic syndrome were followed over three months. The Healthy Eating Index tool adapted to the Brazilian population was used for the evaluation of diet quality. Mean age was 51 + 6 years, and 68.6% were women. The mean score of the dietary quality of the population studied increased significantly from 53.02 to 61.65 after intervention. The amount of individuals classified as Inappropriate Diet decreased significantly six-fold, the amount of individuals classified as Healthy Diet increased four-fold, and the percent of diets classified as Diet that Needs Change decreased by 25% when compared to the beginning of the study. Adequate intake of vegetables was inversely associated to abdominal circumference, as well as adequate intake of sodium and fasting serum insulin. The amount of TEV presented a significant reduction (p <0.000) after intervention. The short-term nutritional counseling showed to be efficient to improve dietary quality. Associations between dietary quality and variables studied highlight the importance of nutritional intervention in individuals with metabolic syndrome.


A Síndrome Metabólica é uma condição clínica complexa que reúne um conjunto de fatores que aumentam o risco cardiovascular. Mudanças no estilo de vida como a melhora dos hábitos alimentares são consideradas terapia de primeira escolha nesta condição clínica. Este estudo tem como objetivo avaliar o efeito de uma intervenção nutricional de curta duração sobre a qualidade da dieta e o valor energético total (VET) em indivíduos com Síndrome Metabólica. Oitenta indivíduos (homens e mulheres) com idades entre 30 a 60 anos, com síndrome metabólica foram acompanhados ao longo de três meses. Para avaliar a qualidade da dieta foi utilizado o instrumento Índice de Alimentação Saudável adaptado para a população brasileira. A média de idade foi de 51 + 6 anos e 68,6% eram mulheres. A pontuação média da qualidade da dieta da população estudada aumentou significativamente de 53,02 para 61,65 após a intervenção. A quantidade de indivíduos classificados como dieta inadequada diminuiu significativamente em seis vezes, a quantidade de indivíduos classificados como dieta saudável aumentou quatro vezes, e a percentagem de dietas classificadas como dieta que necessita modificação diminuiu 25% em relação ao início do estudo. A ingestão adequada de vegetais foi inversamente associada à circunferência abdominal, bem como a ingestão adequada de sódio e insulina sérica de jejum. O VET apresentou uma redução significativa (p <0,000) após a intervenção. O aconselhamento nutricional de curta duração mostrou-se eficiente para melhorar a qualidade da dieta. As associações entre a qualidade da dieta e as variáveis estudadas destacam a importância da intervenção nutricional em indivíduos com síndrome metabólica.

ABSTRACT

Objective: To determine the risk factors related to the development of stroke in patients undergoing cardiac surgery. Methods: A historical cohort study. We included 4626 patients aged > 18 years who underwent coronary artery bypass surgery, heart valve replacement surgery alone or heart valve surgery combined with coronary artery bypass grafting between January 1996 and December 2011. The relationship between risk predictors and stroke was assessed by logistic regression model with a significance level of 0.05. Results: The incidence of stroke was 3% in the overall sample. After logistic regression, the following risk predictors for stroke were found: age 50-65 years (OR=2.11 - 95% CI 1.05-4.23 - P=0.036) and age >66 years (OR=3.22 - 95% CI 1.6-6.47 - P=0.001), urgent and emergency surgery (OR=2.03 - 95% CI 1.20-3.45 - P=0.008), aortic valve disease (OR=2.32 - 95% CI 1.18-4.56 - P=0.014), history of atrial fibrillation (OR=1.88 - 95% CI 1.05-3.34 - P=0.032), peripheral artery disease (OR=1.81 - 95% CI 1.13-2.92 - P=0.014), history of cerebrovascular disease (OR=3.42 - 95% CI 2.19-5.35 - P<0.001) and cardiopulmonary bypass time > 110 minutes (OR=1.71 - 95% CI 1.16-2.53 - P=0.007). Mortality was 31.9% in the stroke group and 8.5% in the control group (OR=5.06 - 95% CI 3.5-7.33 - P<0.001). Conclusion: The study identified the following risk predictors for stroke after cardiac surgery: age, urgent and emergency surgery, aortic valve disease, history of atrial fibrillation, peripheral artery disease, history of cerebrovascular disease and cardiopulmonary bypass time > 110 minutes. .


OBJETIVOS: Determinar os preditores de risco relacionados ao desenvolvimento de acidente vascular cerebral em pacientes que realizaram cirurgia cardíaca. Métodos: Estudo de coorte histórico. Incluímos 4626 pacientes com idade > 18 anos submetidos à cirurgia de revascularização do miocárdio, cirurgia cardíaca valvar isolada ou cirurgia valvar associada com revascularização do miocárdio, de janeiro de 1996 e dezembro de 2011. A relação entre os preditores de risco e o acidente vascular cerebral foi avaliada por modelo de regressão logística com nível de significância de 0,05. Resultados: A incidência de acidente vascular cerebral foi 3% na amostra total. A análise multivariada identificou como preditores de risco para o acidente vascular cerebral: idade 50-65 anos (OR=2,11 - 95% IC 1,05-4,23 - P=0,036) e idade > 66 anos (OR=3,22 - 95% IC 1,6-6,47 - P=0,001), cirurgia de urgência/emergência (OR=2,03 - 95% IC 1,20-3,45 - P=0,008), valvulopatia aórtica (OR=2,32 - 95% IC 1,18-4,56 - P=0,014), fibrilação atrial (OR=1,88 - 95% IC 1,05-3,34 - P=0,032), doença arterial obstrutiva periférica (OR=1,81 - 95% IC 1,13-2,92 - P=0,014), história de doença cerebrovascular (OR=3,42 - 95% IC 2,19-5,35 - P<0,001) e tempo de circulação extracorpórea >110 minutos (OR=1,71 - 95% IC 1,16-2,53 - P=0,007). A mortalidade foi 31,9% nos pacientes que sofreram AVC e 8,5% nos sem AVC (OR=5,06 - 95% IC 3,5-7,33 - P<0,001). Conclusão: Idade, cirurgia de urgência/emergência, doença de valva aórtica, história de fibrilação atrial, doença arterial obstrutiva periférica, história de doença cerebrovascular e tempo de circulação extracorpórea > 110 minutos foram preditores independentes para o desenvolvimento de AVC i...

ABSTRACT

Fundamento: A síndrome metabólica é um transtorno complexo representado por um conjunto de fatores de risco cardiovascular. A adoção de um estilo de vida saudável está fortemente relacionada à melhora da Qualidade de Vida e interfere de forma positiva no controle dos fatores de risco presentes nessa condição clínica. Objetivo: Avaliar o efeito de um programa de modificação do estilo de vida sobre o Escore de Risco Cardiovascular Global de Framingham em indivíduos com síndrome metabólica. Método: Trata-se de uma subanálise de um ensaio clínico randomizado, controlado, cegado, com duração de três meses. Os participantes foram randomizados em quatro grupos: intervenção nutricional + placebo (INP), intervenção nutricional + suplementação de ácidos graxos ômega 3 (3 g/dia de óleo de peixe) (INS3), intervenção nutricional + atividade física + placebo (INEP) e intervenção nutricional + atividade física + suplementação de ácidos graxos ômega 3 (INES3). O Escore de Risco Cardiovascular Global de Framingham de cada indivíduo foi calculado antes e após a intervenção. Resultados: Participaram do estudo 70 indivíduos. Observou-se uma redução da média do escore após a intervenção de forma geral (p < 0,001). Obteve-se uma redução para risco intermediário em 25,7% dos indivíduos. Após a intervenção, observou-se redução significativa (p < 0,01) da "idade vascular", sendo esta mais expressiva nos grupos INP (5,2%) e INEP (5,3%). Conclusão: Todas as intervenções propostas produziram efeito benéfico para a redução do escore de risco cardiovascular. O presente estudo reforça a importância da ...


Background: Metabolic syndrome is a complex disorder represented by a set of cardiovascular risk factors. A healthy lifestyle is strongly related to improve Quality of Life and interfere positively in the control of risk factors presented in this condition. Objective: To evaluate the effect of a program of lifestyle modification on the Framingham General Cardiovascular Risk Profile in subjects diagnosed with metabolic syndrome. Methods: A sub-analysis study of a randomized clinical trial controlled blind that lasted three months. Participants were randomized into four groups: dietary intervention + placebo (DIP), dietary intervention + supplementation of omega 3 (fish oil 3 g/day) (DIS3), dietary intervention + placebo + physical activity (DIPE) and dietary intervention + physical activity + supplementation of omega 3 (DIS3PE). The general cardiovascular risk profile of each individual was calculated before and after the intervention. Results: The study included 70 subjects. Evaluating the score between the pre and post intervention yielded a significant value (p < 0.001). We obtained a reduction for intermediate risk in 25.7% of subjects. After intervention, there was a significant reduction (p < 0.01) on cardiovascular age, this being more significant in groups DIP (5.2%) and DIPE (5.3%). Conclusion: Proposed interventions produced beneficial effects for reducing cardiovascular risk score. This study emphasizes the importance of lifestyle modification in the prevention and treatment of cardiovascular diseases. .
