Factors associated with diet quality among Brazilian individuals with cardiovascular diseases.

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.

Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial.

BACKGROUND: Appropriate dietary recommendations represent a key part of secondary prevention in cardiovascular disease (CVD). We evaluated the effectiveness of the implementation of a nutritional program on quality of diet, cardiovascular events, and death in patients with established CVD. METHODS: In this open-label, multicenter trial conducted in 35 sites in Brazil, we randomly assigned (1:1) patients aged 45 years or older to receive either the BALANCE Program (experimental group) or conventional nutrition advice (control group). The BALANCE Program included a unique nutritional education strategy to implement recommendations from guidelines, adapted to the use of affordable and regional foods. Adherence to diet was evaluated by the modified Alternative Healthy Eating Index. The primary end point was a composite of all-cause mortality, cardiovascular death, cardiac arrest, myocardial infarction, stroke, myocardial revascularization, amputation, or hospitalization for unstable angina. Secondary end points included biochemical and anthropometric data, and blood pressure levels. RESULTS: From March 5, 2013, to Abril 7, 2015, a total of 2534 eligible patients were randomly assigned to either the BALANCE Program group (n = 1,266) or the control group (n = 1,268) and were followed up for a median of 3.5 years. In total, 235 (9.3%) participants had been lost to follow-up. After 3 years of follow-up, mean modified Alternative Healthy Eating Index (scale 0-70) was only slightly higher in the BALANCE group versus the control group (26.2 ±â€¯8.4 vs 24.7 ±â€¯8.6, P < .01), mainly due to a 0.5-serving/d greater intake of fruits and of vegetables in the BALANCE group. Primary end point events occurred in 236 participants (18.8%) in the BALANCE group and in 207 participants (16.4%) in the control group (hazard ratio, 1.15; 95% CI 0.95-1.38; P = .15). Secondary end points did not differ between groups after follow-up. CONCLUSIONS: The BALANCE Program only slightly improved adherence to a healthy diet in patients with established CVD and had no significant effect on the incidence of cardiovascular events or death.

Association between plasma fatty acids and inflammatory markers in patients with and without insulin resistance and in secondary prevention of cardiovascular disease, a cross-sectional study.

BACKGROUND: Proinflammatory biomarkers levels are increased among patients with cardiovascular disease, and it is known that both the presence of insulin resistance and diet may influence those levels. However, these associations are not well studied among patients with established cardiovascular disease. Our objective is to compare inflammatory biomarker levels among cardiovascular disease secondary prevention patients with and without insulin resistance, and to evaluate if there is any association between plasma fatty acid levels and inflammatory biomarker levels among them. METHODS: In this cross-sectional sub-study from the BALANCE Program Trial, we collected data from 359 patients with established cardiovascular disease. Plasma fatty acids and inflammatory biomarkers (interleukin (IL)-1ß, IL-6, IL-8, IL-10, IL-12, high sensitive C-reactive protein (hs-CRP), adiponectin, and tumor necrosis factor (TNF)-alpha) were measured. Biomarkers and plasma fatty acid levels of subjects across insulin resistant and not insulin resistant groups were compared, and general linear models were used to examine the association between plasma fatty acids and inflammatory biomarkers. RESULTS: Subjects with insulin resistance had a higher concentration of hs-CRP (p = 0.002) and IL-6 (p = 0.002) than subjects without insulin resistance. Among subjects without insulin resistance there was a positive association between stearic fatty acid and IL-6 (p = 0.032), and a negative association between alpha-linolenic fatty acid and pro-inflammatory biomarkers (p < 0.05). Among those with insulin resistance there was a positive association between monounsaturated fatty acids and arachidonic fatty acid and adiponectin (p < 0.05), and a negative association between monounsaturated and polyunsaturated fatty acids and pro-inflammatory biomarkers (p < 0.05), as well as a negative association between polyunsaturated fatty acids and adiponectin (p < 0.05). Our study has not found any association between hs-CRP and plasma fatty acids. CONCLUSIONS: Subjects in secondary prevention for cardiovascular disease with insulin resistance have a higher concentration of hs-CRP and IL-6 than individuals without insulin resistance, and these inflammatory biomarkers are positively associated with saturated fatty acids and negatively associated with unsaturated fatty acids.

Adequacy of Fatty Acids Consumption Among Individuals in Secondary Cardiovascular Prevention. / Adequação do Consumo de Ácidos Graxos entre Pacientes em Prevenção Cardiovascular Secundária.

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.

Orange juice intake by obese and insulin-resistant subjects lowers specific plasma triglycerides: A randomized clinical trial.

BACKGROUND & AIMS: Dyslipidaemia is usually common in obesity, insulin resistance, and type 2 diabetes mellitus. Clinical trials suggest that orange juice may have a positive impact on lipid metabolism and blood lipid profiles; however conflicting results have been reported. Here, we applied a combined untargeted/targeted lipidomic analysis of plasma to examine the impact of orange (Citrus sinensis) juice intake on the lipidome profile of obese and insulin-resistant subjects. METHODS: Twenty-five participants, both sexes, aged 40-60 years, with obesity and insulin resistance (homeostasis model assessment of insulin resistance (HOMA-IR) index >2.71) ingested 400 mL of orange juice 'Pera' (C. sinensis) for 15 d. Cardiometabolic biomarkers, anthropometric parameters, blood pressure, and plasma lipidomic analysis results were assessed at the beginning and end of the intervention. RESULTS: After the 15-d intervention, a significant decrease was observed in the diastolic blood pressure and blood lipid profile. Among plasma lipidomes, 316 lipid molecules were identified, with the triglycerides (TGs) subclass being the most abundant (n = 106). Plasma lipidome profiling revealed a major signature of the intervention; with concentrations of 37 TG species decreasing after intervention. Qualitatively, oleic and linoleic acids were among the most prevalent fatty acids linked to the altered TG species, representing 50% of TG chains. Modulated TG species were positively correlated with total TG and very low-density lipoprotein levels, as well as systolic and diastolic blood pressure. A strong inter-individual trend was observed, wherein, compared with less responsive subjects, the high responsive subjects displayed the highest decrease in the concentrations of altered TG species, as as well as systolic blood pressure (decrease of 10.3 ± 6.8 mmHg) and body weight (decrease of 0.67 ± 0.71 kg). CONCLUSIONS: These findings suggest that orange juice has a positive impact on lipid metabolism, mainly regarding the composition of TG-specific fatty acid chains and cholesterol esters, protecting against insulin resistance. Furthermore, lipidomics may help clarify alterations at the molecular level after an intervention, contributing to improve the evaluation of the link between dyslipidaemia, insulin resistance, and nutrition.

The effect of the a regional cardioprotective nutritional program on inflammatory biomarkers and metabolic risk factors in secondary prevention for cardiovascular disease, a randomised trial.

BACKGROUND & AIMS: To evaluate the effect of the Brazilian Cardioprotective Diet Program (BALANCE Program) on inflammatory biomarkers, involved in the pathophysiology of the atherosclerosis, on inflammatory biomarkers, cardiovascular risk factors, and on plasma fatty acids in cardiovascular disease secondary prevention patients. METHODS: In this substudy of the BALANCE Program randomized clinical trial, a total of 369 patients aged 45 years or older, who have experienced cardiovascular disease in the previous 10 years, were included. These patients were randomized into two groups and followed up for six months: BALANCE Program group and control group (conventional nutrition advice). In the initial and six-month final visits, anthropometry (body weight, height and waist circumference), food intake evaluation by 24-h dietary recall, plasma inflammatory biomarkers (IL-6, IL-8, IL-10, IL-12, tumor necrosis factor-α, adiponectin, and C-reactive protein levels), blood pressure, glycemia, insulinemia, lipid profile, and plasma fatty acids levels were evaluated. RESULTS: The BALANCE Program group showed increased plasma alpha-linolenic acid levels (P = 0.008), reduction in waist circumference (P = 0.049) and BMI (P = 0.032). No difference was observed among plasma inflammatory biomarkers and clinical data. CONCLUSION: After six months of follow-up, BALANCE Program led to a significant reduction on BMI and waist circumference in individuals in secondary prevention for cardiovascular disease. Although plasmatic alpha-linolenic acid has increased, there was no impact on plasma inflammatory biomarkers. CLINICAL TRIAL REGISTRATION: NCT01620398.

Unsaturated Fatty Acids Improve Atherosclerosis Markers in Obese and Overweight Non-diabetic Elderly Patients.

BACKGROUND: Several studies have demonstrated the benefits of replacing trans and saturated fats with unsaturated fatty acids on cardiovascular diseases. We aimed to demonstrate the effect of polyunsaturated and monounsaturated fat supplementation on the biochemical and endothelial markers of atherosclerotic disease in obese or overweight non-diabetic elderly patients. METHOD: Seventy-nine patients were randomly divided into three groups: flaxseed oil, olive oil, and sunflower oil; patients in each group received 30 mL of oil for 90 days. Patients were subjected to anthropometric and bioimpedance assessments; biochemical and endothelial evaluations were performed through ultrasonography of the brachial artery and carotid artery for endothelium-dependent dilation and intima-media thickness assessment, respectively, before and after the intervention. The participants' usual diet remained unchanged. RESULTS: The flaxseed oil group had improved ultra-sensitive C-reactive protein levels (p = 0.074) and reduced carotid intima-media thickness (CIMT) (p = 0.028); the olive oil group exhibited an improved apolipoprotein (Apo)B/ApoA ratio (p = 0.021), reduced CIMT (p = 0.028), and improved flow-mediated vasodilation (FMV) (p = 0.054); and similarly, the sunflower oil group showed an improved ApoB/ApoA ratio (p = 0.024), reduced CIMT (p = 0.048), and improved FMV (p = 0.001). CONCLUSION: Unsaturated fatty acid supplementation using the three vegetable oils attenuated pro-inflammatory properties and improved prothrombotic conditions. Therefore, introducing or replacing saturated and trans fat with unsaturated fatty acids is beneficial for cardiovascular risk reduction in obese or overweight non-diabetic elderly people. Further studies are needed to determine which unsaturated fat best prevents cardiovascular disease in elderly patients.

Association between polyunsaturated fatty acids and inflammatory markers in patients in secondary prevention of cardiovascular disease.

OBJECTIVE: The aim of this study was to assess the association between polyunsaturated fatty acids (PUFAs) and inflammatory biomarkers among patients in secondary prevention of cardiovascular disease (CVD). METHODS: In this cross-sectional substudy from BALANCE Program Trial, we have collected data from 364 patients with established CVD. Twenty-four-hour dietary recalls and plasma FA concentrations were analyzed to estimate the FA intake. Inflammatory biomarkers measurement consisted of interleukin (IL)-1ß, IL-6, IL-8, IL-10, IL-12, C-reactive protein, adiponectin, and tumor necrosis factor-α. After log-transformation of inflammatory biomarkers, multivariate-adjusted general linear model was used to examine the effect of FA intake. The association was adjusted for body mass index, waist circumference, energy, smoking status, age, total cholesterol, low-density lipoprotein cholesterol, physical activity, and calcium channel blockers. RESULTS: PUFAs were inversely associated with C-reactive protein levels (P = 0.006) and with IL-1 ß. The increase of 1 g/1000 kcal in PUFAs, omega-3, and omega-6 reduces, on average, 6%, 48%, and 8% respectively, the mean concentration of IL-1 ß. CONCLUSION: Omega-3 and omega-6 FA intakes are inversely associated with inflammatory biomarkers among CVD patients. Additional studies on omega-3 and omega-6 intake in relation to inflammatory biomarkers in patients in secondary prevention of CVD are needed, particularly regarding dietary patterns that are rich in some sources of PUFA.

Análise do consumo alimentar e do estado nutricional de indivíduos submetidos à cirurgia cardíaca eletiva em hospital público de referência em Cardiologia / Analysis of dietary intake and nutritional status of subjects submitted to elective cardiac surgery at a public reference hospital in Cardiology

INTRODUÇÃO: As doenças cardiovasculares representam a principal causa de morte no mundo. Seus fatores de risco são divididos em modificáveis e não-modificáveis. Diversos estudos clínicos vêm demonstrando a influência positiva da dieta na prevenção primária e secundária de eventos cardiovasculares. Dada a importância já documentada de uma dieta equilibrada, assim como do estado nutricional adequado na manutenção da saúde cardiovascular, este estudo objetivou avaliar a adequação da dieta habitual e do estado nutricional de pacientes submetidos a cirurgia cardíaca eletiva em hospital especializado em Cardiologia. MÉTODO: Estudo de caráter descritivo e transversal, com amostra de conveniência, composta por 38 indivíduos adultos, de ambos os sexos, encaminhados para cirurgia eletiva de revascularização do miocárdio, troca de válvula ou cirurgia combinada (revascularização do miocárdio e troca de válvula). A coleta de dados ocorreu no ambulatório de Nutrição do Instituto Dante Pazzanese de Cardiologia, anteriormente à cirurgia cardíaca, sendo realizada coleta de dados demográficos, tipo de cirurgia, antecedentes clínicos, consumo alimentar e avaliação nutricional. RESULTADOS: Na amostra avaliada, 68,42% dos pacientes estavam em sobrepeso e obesidade, segundo o índice de massa corporal. O percentual de gordura corporal apresentou valores acima da normalidade em 96,87% dos pacientes, com circunferência abdominal de risco elevado e muito elevado em 75,68%. Na avaliação habitual da dieta, a adequação no consumo de macronutrientes foi de 47,37%, 2,6% e 44,74% para carboidratos, proteínas e lipídeos respectivamente. Quanto aos ácidos graxos saturados, 36,84% dos pacientes apresentaram consumo superior ao recomendado. Foi observado baixo consumo de frutas, verduras e legumes por 89,48% dos pacientes e, consequentemente, de fibras dietéticas por 97,37%. CONCLUSÃO: Conclui-se que a amostra, composta por pacientes com excesso de peso, percentual de gordura elevado, alto risco cardiovascular e submetidos à cirurgia cardíaca eletiva, apresentou um padrão alimentar com baixo consumo de frutas, verduras, legumes e fibras dietéticas, necessitando de acompanhamento nutricional individualizado.

Is intake of vitamin D and calcium important for cardiovascular health in elderly obese patients?

There is compelling evidence that bariatric weight loss reduces cardiovascular complications; however, these still tend to be the most common cause of late death after surgical intervention. In a prospective cohort study, correlations of dietary nutrients with indexes of vascular health were sought, with emphasis on vitamin D and calcium. Clinically stable obese outpatient subjects (>60 years old, N = 44) were interviewed about dietary macro and micronutrients. Nutritional assessment targeted anthropometric and bioimpedance analysis (BIA), hematologic counts, lipid profile, glucose homeostasis, and inflammatory markers. Carotid intima-media thickness (IMT) and brachial flow-mediated dilation (FMD), along with related vascular measurements, were documented, and results were correlated by uni- and multivariate analysis, corrected for known risk factors. IMT, FMD, and also brachial basal flow were positively influenced by vitamin D (P < 0.001). Calcium appeared beneficial for brachial basal flow only (P = 0.010). No association with IMT occurred, and a negative result for FMD was elicited. Also, vitamins A and B12 were advantageous for FMD, whereas iron was deleterious for IMT. Intake of many micronutrients including calcium and vitamin D did not meet recommendations. Vitamin D displayed a beneficial profile regarding vascular health, and more attention to this nutrient should be given, especially concerning obese patients with cardiometabolic risk. Calcium exhibited less straightforward results but deserves focus as well, along with antioxidant vitamin A as well as the B-complex which were mostly deficient in this experience.

Diferenças estruturais e qualitativas dos óleos de oliva, girassol e linhaça e seus efeitos sobre as doenças cardiovasculares / Structure and qualitative differences in the olive, sunflower and flaxseed oils and their effects on cardiovasculare disease

A qualidade dos lípides na alimentação é um dos principaisfundamentos na prevenção e mortalidade por doenças crônicasnão transmissíveis. Ensaios anteriores já estabeleceramos benefícios das gorduras insaturadas ante as saturadas,principalmente em relação ao ômega 3 (w-3). Mais recentemente,os estudos têm buscado avaliar os efeitos metabólicosde diversos óleos, tanto de forma isolada como associados.Como parte da dieta Mediterrânea, o óleo de oliva pareceexercer papel efetivo na diminuição plasmática de colesterol,especialmente na lipoproteína de baixa densidade (LDL). Entreos óleos ricos em ácidos polinsaturados, o de girassol e o delinhaça estão sendo analisados quanto às suas ações e sobre anecessidade de se estabelecer uma relação de consumo. Esteartigo revisa os conceitos da estrutura química dos óleos deoliva, girassol e linhaça e os efeitos que exercem sobre a saúdecardiovascular.

The importance of lipids in our nutrition is a major corner stone in the prevention and mortality from chronic diseases, both in their quantity, and quality. Previous trials have already establishedthe benefits of unsaturated fats compared to saturated, especially in relation to omega 3 (w-3). More recently, several studies try to evaluate the metabolic effects of different oils,either alone or associated. As part of the Mediterranean diet, olive oil seems to play an effective role in reducing plasmacholesterol, especially in low-density lipoprotein (LDL). Among the oils rich in polyunsaturated acids, the sunflowerand flax seed oils are being analyzed for their actions and the need to establish a consumer relationship. This article reviews the concept of the chemical structure of olive oil, sunflower oil and flaxseed oil, and their effects on cardiovascular health.

Revisão de artigos: realidade sobre a interação de alimentos com anticoagulantes orais / Articles review: the reality about the interactions among food and oral anticoagulants

Este artigo revisa várias publicações científicas sobre interações de anticoagulantes orais com fatores dietéticos, relatando a deficiência do conhecimento sobre essas interações, e sugere aplicações clínicas. Como em muitas interações entre droga-nutriente, as referências originais incluem alguns estudos experimentais e casos correlatos, e apresentam, sobretudo, quais interações de anticoagulantes orais com fatores dietéticos são clinicamente pertinentes, determinando a prescrição dietética apropriada para cada interação. Existem muitos estudos sobre a vitamina K em alimentos e sobre sua quantidade, que pode alterar o estado de coagulação do índice terapêutico, com o objetivo de proporcionar ao paciente orientação do grupo de alimentos que devem ser evitados, posologia, etc. A respeito de outros fatores dietéticos que podem interagir com anticoagulantes orais, o paciente deveria ter relativa cautela quanto ao uso de suplementos de vitaminas A, E, C e álcool, em especial quando usados cronicamente ou quando ingeridos em grandes quantidades. Os estudos existentes não são conclusivos, possuindo apenas opiniões baseadas em pesquisas extensas.
