Evaluate the nutritional status of patients with cardiac disease and concomitant renal dysfunction requiring renal replacement therapy.Patients with cardiac disease and renal failure receiving renal replacement therapy, admitted to an intensive care unit, were submitted to nutritional evaluation, by use of anthropometric measurements and laboratory data.We studied 43 patients, mean age 64±15 years, 26 were men. The mean left ventricular ejection fraction was 0.36±0.16. Analysis of anthropometric measurements, based on body mass index disclosed that, 18 patients were normal, 6 were underweight and 19 were overweight or obese. Based on measurement of triceps skinfold thickness, 16 patients were considered normal and 27 had some degree of depletion. Measurements of midarm circumference and midarm muscular circumference showed 41 patients with some degree of depletion. Laboratory data revealed 28 patients with depletion based on albumin levels and 27 with depletion based on lymphocyte count.Malnutrition is common in critically ill patients with cardiac disease and renal failure receiving renal replacement therapy. Nutritional assessment based on body mass index did not prove to be a good index for diagnosis of nutritional disorders. The nutritional evaluation must be complemented in order to identify malnutrition and introduce early nutritional support. |
