Abstract Background In most cases, atherosclerotic cardiovascular disease (ACVD) is preventable through primary prevention and control of traditional risk factors, such as smoking cessation, regular physical activity, and adherence to healthy dietary patterns. The assessment of diet quality of ACVD patients would be important for a dietary intervention. Objectives This study aimed to evaluate diet quality of ACVD patients and its association with clinical conditions. Methods This cross-sectional study was nested within a randomized clinical trial entitled “Programa Alimentar Cardioprotetor Brasileiro.” Baseline data of 80 patients from Pelotas, Brazil, were obtained. Food consumption was assessed using 24-h food recall and the Revised Diet Quality Index (IQD-R). Data on smoking status and comorbidities were reported by the patients during medical history taking. To analyze the associations between IQD-R and clinical variables, unpaired Student’s t-test or the analysis of variance was performed. The significance level was 5%. Results Most of the sample consisted of men (66.5%), elderly individuals (52.50%), patients with hypertension (78.75%), dyslipidemia (58.75%), and overweight (73.75%). The average IQD-R score was 56.7 ± 12.6 points. Better quality of diet was observed for patients with diabetes compared to those without diabetes (61.1 ± 11.8 versus 54.0 ± 12.6 points; p=0.014). Conclusion There is a need to improve diet quality of ACVD patients. Patients ACVD and diabetes had better diet quality compared to those without diabetes.

ABSTRACT Objectives: Paraoxonase 1 (PON1) is an enzyme that has antioxidant potential, which confers a protective effect against the atherosclerotic process. However, studies associating genetics, dietary patterns and PON1 activity in individuals with cardiovascular disease (CVD) are scarce. Thus, the aim of the current study was to evaluate the influence of dietary factors on serum PON1 in CVD patients. Subjects and methods: Cross-sectional, sub-study of the BALANCE Program Trial. All patients aged 45 years or older and had evidence of established atherosclerotic disease in the preceding 10 years. Body weight, height, waist circumference, blood pressure, lipid profile and fasting glucose were collected. Food intake was assessed with 24-h dietary recall. Data was analyzed using SAS University Edition and a P value ≤ 0.05 was considered statistically significant. Sample was divided into three groups, according to the PON1 T(-107)C genotype (CC, CT and TT) and serum PON1 activity (Low, Medium, High). Results: There were no genotype differences for major factors. However, the systolic blood pressure was lower for CT individuals (p<0.05). Intake of cholesterol, saturated fatty acids (SFA) and monounsaturated fatty acids (MUFAS) was higher in patients with lower PON1 activity. Lipid ingestion tended to be higher in patients with lower PON1 activity (p=0.08). In the multivariate logistic regression model, SFA intake (P=0.03), genotype (P=0.09), gender (P=0.04), age (P=0.07) and carbohydrate intake (P=0.16) contributed the most to the serum PON1 activity. Conclusion: Based on these findings, nutritional guidance for these patients becomes essential, since dietary components interact with serum PON1 activity more than genotype.

Resumo O presente estudo investigou a associação entre o consumo de bebidas açucaradas e variáveis antropométricas e bioquímicas em análise transversal, realizado com dados secundários referentes à primeira consulta do ensaio clínico randomizado Dieta Cardioprotetora Brasileira (2013-2014). Foram coletados peso, altura, circunferência da cintura, perfil lipídico e glicemia de jejum e dados de um recordatório alimentar de 24 horas. Diferenças entre o consumo e não consumo de bebidas açucaradas foram avaliadas pelo teste T de student. Para analisar a associação entre o consumo de bebidas açucaradas e fatores bioquímicos e antropométricos foi utilizado o teste qui quadrado. A amostra foi de 2.172 indivíduos, sendo a maioria homens (58,5%), idosos (63,6%), do nível econômico C (57,3%), com ensino fundamental (45,8%) e com excesso de peso (62,7%). Houve associação significativa entre o consumo de bebidas açucaradas e maior valores de índice de massa corporal (p=0,029), circunferência da cintura (p=0,004) e triglicerídeos (p=0,023). Esses resultados reforçam a necessidade de intervenção nutricional quanto ao consumo de bebidas açucaradas como parte do tratamento dietético desta população.

Abstract This study investigated the association between consumption of sugar-sweetened beverages and anthropometric and biochemical variables in a cross-sectional study conducted with secondary data from the first visit of the randomized clinical trial of the Brazilian Cardioprotective Nutritional Program (BALANCE Program) (2013-2014). Weight, height, waist circumference, lipid profile and fasting glycemia and a 24-hour diet recall were collected. Differences between consumption and non-consumption of sugar-sweetened beverages were evaluated by Student’s t-test. The Chi-square test was employed to analyze the association between consumption and non-consumption of sugar-sweetened beverages and biochemical and anthropometric factors. The sample consisted of 2,172 individuals, mostly men (58.5%), elderly (63.6%), C-rated economic class (57.3%), and overweight (62.7%). A statistically significant difference was found between the consumption of sugar-sweetened beverages and higher BMI values (p=0.029), waist circumference (p=0.004) and triglycerides (p=0.023). These results emphasize the need for nutritional intervention regarding the consumption of sugar-sweetened beverages as part of the dietary treatment of this population.

FUNDAMENTO: Já foi demonstrado o uso do NT-proBNP pré-operatório para prever resultado cardíaco adverso, embora estudos recentes tenham sugerido que a determinação do NT-proBNP pós-operatório possa fornecer um valor adicional em pacientes submetidos à cirurgia não cardíaca. OBJETIVO: Avaliar o valor prognóstico perioperatório do NT-proBNP em pacientes de intermediário e alto risco cardiovascular submetidos à cirurgia não cardíaca. MÉTODOS: Este estudo incluiu prospectivamente 145 pacientes com idade > 45 anos, com pelo menos um fator de risco do Índice de Risco Cardíaco Revisado e submetidos à cirurgia de médio ou alto risco não-cardíaca. Os níveis de NTproBNP foram medidos no pré e pós-operatório. Preditores cardíacos de curto prazo foram avaliados por modelos de regressão logística. RESULTADOS: Durante uma mediana de acompanhamento de 29 dias, 17 pacientes (11,7%) apresentaram eventos cardíacos adversos importantes (MACE - 14 infartos do miocárdio não fatais, 2 paradas cardíacas não-fatais e 3 mortes cardíacas). Os níveis ótimos de limiar discriminatório para o NT-proBNP pré e pós-operatório foram 917 e 2962 pg/ mL, respectivamente. O NT-proBNP pré e pós-operatório (OR = 4,7, IC 95%: 1,62-13,73, p = 0,005 e OR 4,5, IC 95%: 1,53-13,16, p = 0,006) foram associados de forma significativa com MACE (eventos cardíacos adversos maiores). O NTproBNP pré-operatório foi significativa e independentemente associado com eventos cardíacos adversos em análise de regressão multivariada (OR ajustado 4,2, IC 95%: 1,38-12,62, p = 0,011). CONCLUSÃO: O NT-proBNP é um importante marcador de curto prazo de eventos cardiovasculares perioperatórios em pacientes de alto risco. Os níveis pós-operatórios foram menos informativos do que os níveis pré-operatórios. Uma única medição de NT-proBNP pré-operatório deve ser considerada na avaliação de risco pré-operatório.

BACKGROUND: Preoperative NT-proBNP has been shown to predict adverse cardiac outcomes, although recent studies suggested that postoperative NT-proBNP determination could provide additional information in patients submitted to noncardiac surgery. OBJECTIVE: To evaluate the prognostic value of perioperative NT-proBNP in intermediate and high risk cardiovascular patients undergoing noncardiac surgery. METHODS: This study prospectively enrolled 145 patients aged >45 years, with at least one Revised Cardiac Risk Index risk factor and submitted to intermediate or high risk noncardiac surgery. NT-proBNP levels were measured pre- and postoperatively. Short-term cardiac outcome predictors were evaluated by logistic regression models. RESULTS: During a median follow-up of 29 days, 17 patients (11.7%) experienced major adverse cardiac events (MACE- 14 nonfatal myocardial infarctions, 2 nonfatal cardiac arrests and 3 cardiac deaths). The optimum discriminatory threshold levels for pre- and postoperative NT-proBNP were 917 and 2962 pg/mL, respectively. Pre- and postoperative NT-proBNP (OR 4.7; 95% CI 1.62-13.73; p=0.005 and OR 4.5; 95% CI 1.53-13.16; p=0.006) were significantly associated with MACE. Preoperative NT-proBNP was significantly and independently associated with adverse cardiac events in multivariate regression analysis (adjusted OR 4.2; 95% CI 1.38-12.62; p=0.011). CONCLUSION: NT-proBNP is a powerful short-term marker of perioperative cardiovascular events in high risk patients. Postoperative levels were less informative than preoperative levels. A single preoperative NT-proBNP measurement should be considered in the preoperative risk assessment.
