RESUMEN

BACKGROUND: Heart failure (HF), a common cause of hospitalization, is associated with poor short-term clinical outcomes. Little is known about the long-term prognosis of patients with HF in Latin America. METHODS: BREATHE was the first nationwide prospective observational study in Brazil that included patients hospitalized due to acute HF. Patients were included during 2 time periods: February 2011-December 2012 and June 2016-July 2018. In-hospital management and 12-month clinical outcomes were assessed, and adherence to evidence-based therapies was evaluated. RESULTS: A total of 3013 patients were enrolled at 71 centers in Brazil. At hospital admission, 83.8% had clear signs of pulmonary congestion. The main cause of decompensation was poor adherence to HF medications (27.8%). Among patients with reduced ejection fraction, concomitant use of beta-blockers, renin-angiotensin-aldosterone inhibitors, and spironolactone numerical decreased from 44.5% at hospital discharge to 35.2% at 3 months. The cumulative incidence of mortality at 12 months was 27.7%, with 24.3% readmission at 90 days and 44.4% at 12 months. CONCLUSIONS: In this large national prospective registry of patients hospitalized with acute HF, rates of mortality and readmission were higher than those reported globally. Poor adherence to evidence-based therapies was common at hospital discharge and 12 months of follow-up.

RESUMEN

BACKGROUND: An individual's dietary pattern contributes in different ways to the prevention and control of recurrent cardiovascular events. However, the quality of the diet is influenced by several factors. The present study aimed to evaluate the quality of the diet of individuals with cardiovascular diseases and determine whether there is an association between sociodemographic and lifestyle factors. METHODS: This is a cross-sectional study carried out with individuals with atherosclerosis (coronary artery disease, cerebrovascular disease or peripheral arterial disease) recruited from 35 reference centres for the treatment of cardiovascular disease in Brazil. Diet quality was assessed according to the Modified Alternative Healthy Eating Index (mAHEI) and stratified into tertiles. For comparing two groups, the Mann-Whitney or Pearson's chi-squared tests were used. However, for comparing three or more groups, analysis of variance or Kruskal-Wallis was used. For the confounding analysis, a multinomial regression model was used. p < 0.05 was considered statistically significant. RESULTS: In total, 2360 individuals were evaluated: 58.5% male and 64.2% elderly. The median (interquartile range [IQR]) of the mAHEI was 24.0 (20.0-30.0), ranging from 0.4 to 56.0 points. When comparing the odds ratios (ORs) for the low (first tertile) and medium (second tertile) diet quality groups with the high-quality group (third tertile), it was observed that there was an association between diet quality with a family income of 1.885 (95% confidence intervals [CI] = 1.302-2.729) and 1.566 (95% CI = 1.097-2.235), as well as physical activity of 1.391 (95% CI = 1.107-1.749) and 1.346 (95% CI = 1.086-1.667), respectively. In addition, associations were observed between diet quality and region of residence. CONCLUSIONS: A low-quality diet was associated with family income, sedentarism and geographical area. These data are extremely relevant to assist in coping with cardiovascular disease because they enable an assessment of the distribution of these factors in different regions of the country.

RESUMEN

INTRODUÇÃO: A organização de uma diretriz clínica é tarefa complexa, que necessariamente deve envolver planejamento prévio, coordenação apropriada, revisão aprofundada da literatura científica, com envolvimento de múltiplos profissionais da área da saúde com notório reconhecimento. A elaboração de uma diretriz clínica de insuficiência cardíaca é ainda mais difícil, por conta da complexidade da síndrome, da amplitude das evidências científicas que permeiam o tópico e do grande impacto que as recomendações propostas têm sobre os pacientes, a comunidade médica e a sociedade como um todo. No presente documento, o Departamento de Insuficiência Cardíaca (DEIC) da Sociedade Brasileira de Cardiologia (SBC) apresenta uma revisão e uma atualização detalhadas de sua Diretriz de Insuficiência Cardíaca Crônica. Os trabalhos se iniciaram em setembro de 2017, com a definição da Comissão Coordenadora, que estabeleceu prioridades, dividiu grupos de trabalho e definiu o cronograma das atividades. Os grupos de trabalho, compostos por três a cinco participantes, deram início a intensas discussões virtuais, que culminaram com a redação de tabelas preliminares, sendo posteriormente amplamente divulgadas e revisadas pelos 34 participantes da diretriz. As discussões finais foram realizadas em reunião presencial em março de 2018, com a participação de todos os colaboradores, nas quais as principais recomendações foram votadas individualmente. As decisões quanto à classe das recomendações foram definidas por maioria plena (concordância de mais de 75% dos participantes). As recomendações terapêuticas propostas no presente documento se embasam nas evidências científicas mais atuais, considerando não apenas aspectos de eficácia clínica demonstrados em grandes ensaios clínicos, mas também contextualizando seus achados para o cenário de saúde brasileiro e incorporando aspectos econômicos definidos em estudos de custo-efetividade. Buscamos sumarizar as principais recomendações em fluxogramas e algoritmos de fácil entendimento e grande aplicabilidade clínica, propondo abordagens para o diagnóstico e o tratamento da síndrome em formato moderno, atualizado e didático. Na última seção da diretriz, o que não podemos deixar de fazer e o que não devemos fazer no diagnóstico, prevenção e tratamento da síndrome foram sumarizados em apenas três tabelas. Em especial, destacamos seis intervenções que foram consideradas de alta prioridade, por apresentarem relações de custo-efetividade altamente favoráveis. Sobretudo, esperamos que a publicação deste documento possa auxiliar na redução das elevadas taxas de mortalidade que ainda estão associadas com a insuficiência cardíaca no Brasil, além de minimizar o cruel impacto que a síndrome causa na qualidade de vida de nossos pacientes. Acreditamos que esta diretriz apresenta, de forma hierarquizada, a linha mestra que deve nortear a prática clínica em diferentes níveis de atenção à saúde, permitindo reconhecimento precoce de pacientes em risco, diagnóstico apropriado e implementação de tratamento de forma escalonada, eficaz e coerente com nossa realidade.
