          Abstract

          FUNDAMENTO: Maior conhecimento sobre o estado nutricional e a ingestão de energia e nutrientes é necessário para auxiliar no tratamento de pacientes com insuficiência cardíaca (IC). OBJETIVO: Verificar o estado nutricional e analisar a adequação da ingestão de energia, macro e micronutrientes de pacientes com IC em atendimento ambulatorial. MÉTODOS: Foram coletados dados antropométricos e de ingestão alimentar habitual de 125 pacientes (72% homens, 52,1±9,8 anos, IMC 26,9±4,4 kg/m²). As variáveis antropométricas foram comparadas entre os sexos, e analisou-se a adequação da ingestão de energia e nutrientes perante as recomendações. RESULTADOS: Depleção ou risco de depleção das reservas musculares estava presente em 38,4% dos pacientes (associação com sexo masculino; p < 0,0001). Em 69,6% dos casos, a ingestão média de energia foi menor que as necessidades energéticas (p < 0,0001). Entre os micronutrientes analisados, magnésio, zinco, ferro e tiamina apresentaram prevalências de inadequação importantes, e a maioria dos pacientes teve consumo de cálcio e potássio abaixo da ingestão adequada e consumo de sódio acima. CONCLUSÃO: Pacientes ambulatoriais com IC apresentam depleção de reservas musculares, com ingestão inadequada de energia e diversos nutrientes. Não se observou associação significante entre quantidade de energia proveniente da dieta habitual e o estado nutricional. O acompanhamento multiprofissional deve ser estimulado para avaliar melhor o estado geral desses pacientes.

          SUMMARY: Increased knowledge about nutritional status and energy and nutrient intakes is required to improve the treatment of patients with heart failure (HF). OBJECTIVES: To verify the nutritional status and evaluate the adequacy of energy, macronutrient and micronutrient intakes in patients with HF in outpatient clinical settings. METHODS: We collected anthropometric and habitual dietary intake data of 125 patients (72% men, 52.1 ± 9.8 years, BMI 26.9 ± 4.4 kg/m2). Anthropometric variables were compared between genders, and the adequacy of energy and nutrient intakes was analyzed according to current recommendations. RESULTS: Muscle depletion or risk of depletion was present in 38.4% of patients (association with male gender, p <0.0001). In 69.6% of cases the mean energy intake was lower than the one required (p <0.0001). Among the micronutrients evaluated in this study, there was an important prevalence of inadequacy in magnesium, zinc, iron and thiamine intakes, and most patients had calcium and potassium intakes below the adequate levels, and sodium intake above the adequate levels. CONCLUSIONS: Outpatients with HF showed muscle depletion, and inadequate energy and nutrient intakes. There was no significant association between habitual dietary energy intake and nutritional status. Multidisciplinary care should be encouraged to better assess the general condition of these patients.

          Obesity and the risk of heart failure.

          Extreme obesity is recognized to be a risk factor for heart failure. It is unclear whether overweight and lesser degrees of obesity also pose a risk. We investigated the relation between the body-mass index (the weight in kilograms divided by the square of the height in meters) and the incidence of heart failure among 5881 participants in the Framingham Heart Study (mean age, 55 years; 54 percent women). With the use of Cox proportional-hazards models, the body-mass index was evaluated both as a continuous variable and as a categorical variable (normal, 18.5 to 24.9; overweight, 25.0 to 29.9; and obese, 30.0 or more). During follow-up (mean, 14 years), heart failure developed in 496 subjects (258 women and 238 men). After adjustment for established risk factors, there was an increase in the risk of heart failure of 5 percent for men and 7 percent for women for each increment of 1 in body-mass index. As compared with subjects with a normal body-mass index, obese subjects had a doubling of the risk of heart failure. For women, the hazard ratio was 2.12 (95 percent confidence interval, 1.51 to 2.97); for men, the hazard ratio was 1.90 (95 percent confidence interval, 1.30 to 2.79). A graded increase in the risk of heart failure was observed across categories of body-mass index. The hazard ratios per increase in category were 1.46 in women (95 percent confidence interval, 1.23 to 1.72) and 1.37 in men (95 percent confidence interval, 1.13 to 1.67). In our large, community-based sample, increased body-mass index was associated with an increased risk of heart failure. Given the high prevalence of obesity in the United States, strategies to promote optimal body weight may reduce the population burden of heart failure. Copyright 2002 Massachusetts Medical Society

            Anthropometric measurement of muscle mass: revised equations for calculating bone-free arm muscle area.

            Arm muscle area (AMA, cm2) is currently calculated from triceps skinfold thickness (TSF, cm), and midarm circumference (MAC, cm). In assessing the accuracy of the current equation by comparison to AMA measured by computerized axial tomography, error in each of the four approximations made was found to result in a 20 to 25% overestimate of AMA. Two correctible error sources were: a 10 to 15% overestimation caused by assuming a circular midarm muscle compartment and a 5 to 10% overestimation due to inclusion of midarm cross-sectional bone area. Corrected AMA equations for men and women were respectively: [(MAC - pi x TSF)2/4 pi] - 10, and [MAC - pi x TSF)2/4 pip] - 6.5. With two additional study groups, the overall improved accuracy of the new equations was confirmed, although the average error for a given patient was 7 to 8%; the relationship between corrected AMA and total body muscle mass was established [muscle mass (kg) = (ht, cm2) (0.0264 + 0.0029 x corrected AMA)]; and the minimal range of corrected AMA values compatible with survival (9 to 11 cm2) was defined. Bedside estimates of undernutrition severity and prognosis can therefore be calculated from two simple measurements, TSF and MAC.

              Plasma adiponectin, body mass index, and mortality in patients with chronic heart failure.

              Recent studies have suggested that higher body mass index (BMI) is associated with improved prognosis in chronic heart failure (CHF). The adipocytokine adiponectin is inversely associated with BMI, and in healthy subjects, low adiponectin is a predictor of mortality. In a prospective study, we therefore evaluated the association between plasma adiponectin levels and mortality among patients with CHF. In 195 CHF patients (age 69.3+/-10.2 years, BMI 27.3+/-5.2 kg/m2, left ventricular ejection fraction 30+/-8.9%, mean+/-SD), plasma adiponectin and N-terminal pro brain natriuretic peptide (NT-proBNP) were measured at baseline. Adiponectin was positively associated with NT-proBNP (beta=0.47, P<0.001), and both biomarkers were negatively associated with BMI (beta=-0.43, P<0.001 for adiponectin and beta=-0.38, P<0.001 for NT-proBNP, respectively) During a median follow-up of 2.6 years, 46 (23.5%) of the patients died. After adjustment for clinical variables associated with CHF severity (age, systolic blood pressure, left ventricular ejection fraction <25%, duration of CHF, and creatinine clearance) and for NT-proBNP, the hazard ratio of mortality for values in the 2 upper tertiles relative to the lowest tertile of adiponectin was 3.23 (P=0.032). BMI predicted mortality independently of clinical parameters of CHF severity (hazard ratio=0.63, P=0.012), but this association became insignificant after additional adjustment for NT-proBNP (hazard ratio=0.74, P=0.13). A high adiponectin level was a predictor of mortality, independent of risk markers of CHF severity, presumably because of its role as a marker for wasting. BMI was also associated with mortality, but a part of this relation may be mediated by adiponectin and NT-proBNP levels.
