Resumo
Patients with chronic heart failure (CHF) may develop a wasting syndrome, termed cardiac cachexia. This condition should be diagnosed when weight loss of more than 7.5% of the premorbid normal weight occurs over a time period of more than 6 months. Although the pathophysiologic causes of body wasting in patients with CHF remain unclear, studies have suggested that reduction of the dietary ingestion, intestinal malabsorption of nutrients, increased resting metabolic rates, and humoral neuroendocrine and immunologic abnormalities may play a role. The development of cachexia in the patients with CHF results in clinical symptoms, adverse consequences on the heart, and impaired survival.
