Assessment of Malnutrition in Heart Failure and Its Relationship with Clinical Problems in Brazilian Health Services.

Malnutrition in heart failure (HF) is frequent and associated with a worse prognosis. Due to differences in investment and the profile of those assisted, the objective of this study was to evaluate the frequency of malnutrition in hospitalized patients with HF and its association with clinical outcomes in the public and private health systems. Methodology: A cross-sectional study, with 247 volunteers hospitalized with HF in three public hospitals and one private hospital in Aracaju, SE, Brazil. A subjective global nutritional assessment (SGA) and mini nutritional assessment (MNA) were performed. Results: Sample with 72.5% users of the public health system and 75.3% with malnutrition (public = 74.9%; private = 76.5%; p = 0.793). Regardless of the healthcare system, hospital stay (>14 days) was longer (p = 0.020) among those with malnutrition (48.4%) than well-nourished patients (29.5%). Malnutrition in the public system had higher mortality (7.5%; 5.8%; p < 0.001) and hospital transfer rate (21.1%; 0.0%; p < 0.001) than those in the private system. Death after discharge was observed only in the public system (p = 0.039). Conclusion: Malnutrition was frequent in both systems and was associated with longer hospital stays and, in the public hospital, in-hospital death and transfers.

Food Patterns of Hospitalized Patients with Heart Failure and Their Relationship with Demographic, Economic and Clinical Factors in Sergipe, Brazil.

Background: The high rates of hospitalization and mortality caused by Heart Failure (HF) have attracted the attention of health sectors around the world. Dietary patterns that involve food combinations and preparations with synergistic or antagonistic effects of different dietary components can influence the worsening and negative outcomes of this disease. Objectives: To describe the dietary patterns of patients hospitalized for HF decompensation and associate them with demographic, economic, and clinical factors, and the type of care provided in Sergipe. Materials and Methods: Cross-sectional study that is part of the Congestive Heart Failure Registry (VICTIM-CHF)" of Aracaju/SE. Prospective data collection took place with all patients hospitalized between April 2018 and February 2021 in cardiology referral hospitals, 2 public and 1 private. The data collected were sociodemographic, clinical, lifestyle, anthropometric and food consumption variables. Daily dietary intake was estimated by applying a semiquantitative food frequency questionnaire. The extraction of dietary patterns, by exploratory factor analysis, was performed after grouping the foods according to the nutritional value and form of preparation into 34 groups. To assess the association between the factorial scores for adherence to the standards and the variables studied, the Mann-Whitney U test was applied. Linear regressions were also performed, considering the dietary pattern (one for each pattern) as a dependent variable. Results: The study included 240 patients hospitalized for HF decompensation, most of them elderly (mean age 61.12 ± 1.06 years), male (52.08%) and attended by the Unified Health System­SUS (67.5%). Three dietary patterns were identified, labeled "traditional" (typical foods of the Brazilian northeastern population added to ultra-processed foods), "Mediterranean" (foods recommended by the Mediterranean diet) and "dual" (healthy foods combined with fast and easy-to-prepare foods like snacks, bread, sweets and desserts). Adherence to the "traditional" pattern was greater among men (p < 0.031) and non-diabetics (p < 0.003). The "Mediterranean" was more consumed by the elderly (p < 0.001), with partners (p = 0.001) and a lower income (p < 0.001), assisted by the SUS (p < 0.001) and without hypertension (p = 0,04). The "dual" diet pattern had greater adherence by the elderly (p < 0.001), self-declared non-black (p = 0.012), with higher income (p < 0.001), assisted in the private sector (p < 0.001) and with less impaired functional capacity (p = 0.037). It was also observed that being female (p = 0.031) and being older reduced the average scores of performing the "traditional" pattern (p = 0.002). Regarding the type of service, being from the public service reduced the average scores for adhering to the "dual" pattern (p = 0.008). Conclusions: Three dietary patterns representative of the population were found, called traditional, Mediterranean and dual, which were associated with demographic, economic and clinical factors. Thus, these standards must be considered in the development of nutritional strategies and recommendations in order to increase adherence to diets that are more protective against cardiovascular diseases.

Assessment of Myocardial Ischemia in Obese Individuals Undergoing Physical Stress Echocardiography (PSE) / Avaliação da Isquemia Miocárdica em Obesos Submetidos à Ecocardiografia sob Estresse Físico

Background: Physical stress echocardiography is an established methodology for diagnosis and risk stratification of coronary artery disease in patients with physical capacity. In obese (body mass index ≥ 30 kg/m2) the usefulness of pharmacological stress echocardiography has been demonstrated; however, has not been reported the use of physical stress echocardiography in this growing population group. Objective: To assess the frequency of myocardial ischemia in obese and non-obese patients undergoing physical stress echocardiography and compare their clinical and echocardiographic differences. Methods: 4,050 patients who underwent treadmill physical stress echocardiography were studied according to the Bruce protocol, divided into two groups: obese (n = 945; 23.3%) and non-obese (n = 3,105; 76.6%). Results: There was no difference regarding gender. Obese patients were younger (55.4 ± 10.9 vs. 57.56 ± 11.67) and had a higher frequency of hypertension (75.2% vs. 57, 2%; p < 0.0001), diabetis mellitus (15.2% vs. 10.9%; p < 0.0001), dyslipidemia (59.5% vs 51.9%; p < 0.0001), family history of coronary artery disease (59.3% vs. 55.1%; p = 0.023) and physical inactivity (71.4% vs. 52.9%, p < 0.0001). The obese had greater aortic dimensions (3.27 vs. 3.14 cm; p < 0.0001), left atrium (3.97 vs. 3.72 cm; p < 0.0001) and the relative thickness of the ventricule (33.7 vs. 32.8 cm; p < 0.0001). Regarding the presence of myocardial ischemia, there was no difference between groups (19% vs. 17.9%; p = 0.41). In adjusted logistic regression, the presence of myocardial ischemia remained independently associated with age, female gender, diabetes and hypertension. Conclusion: Obesity did not behave as a predictor of the presence of ischemia and the physical stress echocardiography. The application of this assessment tool in large scale sample demonstrates the feasibility of the methodology, also in obese. .

Fundamento: A ecocardiografia sob estresse físico é a metodologia estabelecida para diagnóstico e estratificação de risco de doença arterial coronária em pacientes com capacidade física preservada. Em obesos (índice de massa coporal ≥ 30 kg/m2), já foi demonstrada a utilidade da ecocardiografia sob estresse farmacológico. Todavia, não tem sido relatado o uso da ecocardiografia sob estresse físico nesse grupo crescente da população. Objetivo: Avaliar a frequência de isquemia miocárdica em obesos e não obesos submetidos à ecocardiografia sob estresse físico, e comparar suas diferenças clínicas e ecocardiográficas. Métodos: Foram estudados 4.050 pacientes, submetidos à ecocardiografia sob estresse físico em esteira ergométrica, segundo o protocolo de Bruce, divididos em dois grupos: obesos (n = 945; 23,3%) e não obesos (n = 3.105; 76,6%). Resultados: Não houve diferença quanto ao sexo. Os obesos foram mais jovens (55,4 ± 10,9 anos vs. 57,56 ± 11,7 anos) e apresentaram maior frequência de hipertensão arterial sistêmica (75,2% vs. 57,2%; p < 0,0001), diabetes melito (15,2% vs. 10,9%; p < 0,0001), dislipidemia (59,5% vs. 51,9%; p < 0,0001), antecedentes familiares para doença arterial coronária (59,3% vs. 55,1%; p = 0,023) e de sedentarismo (71,4% vs. 52,9%; p < 0,0001). Os obesos apresentaram maiores dimensões da aorta (3,27 vs. 3,14 cm; p < 0,0001) do átrio esquerdo (3,97 vs. 3,72 cm; p < 0,0001) e da espessura relativa do ventrículo esquerdo (33,7cm vs. 32,8 cm; p < 0,0001). Quanto à presença de isquemia miocárdica, não houve diferença entre os grupos (19% vs. 17,9%; p = 0,41). Na regressão logística ajustada, isquemia miocárdica permaneceu associada de maneira independente a idade, sexo feminino, diabetes melito e hipertensão arterial sistêmica. Conclusão: A obesidade não se comportou como fator preditor de presença de isquemia à ecocardiografia sob estresse físico. A aplicação desse instrumento de avaliação ...
