Abstract

Chronic heart failure (CHF) is often accompanied by a loss of total body fat and lean body mass, particularly skeletal muscle. Lean body mass has been shown to be an important predictor of survival with end-stage heart disease. Moreover, Italian data on the prevalence of malnutrition in CHF are lacking. Therefore, the aims of our study were: 1) to establish the prevalence of malnutrition in a large CHF population; 2) to measure resting energy expenditure (REE) (indirect calorimetry), the increase of which could contribute to undernutrition in CHF pts. As criteria for malnutrition we adopted: actual body weight less than 90% of ideal body weight (<90%) or triceps skinfold <5° percentile of Muscular Mass Area <5° percentile (MMA <5° percentile) or serum albumin <3.5 g/dL or serum prealbumin <17 mg/dL. Thus it was possible to detect a prevalence of malnutrition in 41.9% of the CHF pts. REE/Kg was significantly higher in pts <90% than in normoweight (90-110%; p = 0.005) and in overweight pts (> 110%; p <0.001), respectively. In conclusion, our results show: 1) malnutrition is present in a large population; 2) normal weight is not synonymous with normonutrition; 3) a hypermetabolic status may exist in underweight pts; 4) MMA is a simple and useful parameter to detect protein malnutrition in CHF pts.
