We investigated the nutritional adequacy and energy availability in 57 normal-weight patients with chronic heart failure (HF) and 49 matched healthy sedentary subjects. We found that the chronic HF patients had a higher total energy expenditure (1,700 +/- 53 vs 1,950 +/- 43 kcal/day; p <0.01), a negative calorie balance (104 +/- 35 vs -186 +/- 40 kcal/day; p <0.01), a negative nitrogen balance (2.2 +/- 0.5 vs -1.7 +/- 0.4 g/day; p <0.01), and a hypercatabolic hormonal status (cortisol/insulin ratio 32 +/- 1.7 vs 65 +/- 5.1; p <0.01). We conclude that patients with chronic HF had an inadequate calorie intake to support energetic needs for daily activities, with consequent important protein breakdown that causes muscular wasting

Abstract

We investigated the nutritional adequacy and energy availability in 57 normal-weight patients with chronic heart failure (HF) and 49 matched healthy sedentary subjects. We found that the chronic HF patients had a higher total energy expenditure (1,700 +/- 53 vs 1,950 +/- 43 kcal/day; p <0.01), a negative calorie balance (104 +/- 35 vs -186 +/- 40 kcal/day; p <0.01), a negative nitrogen balance (2.2 +/- 0.5 vs -1.7 +/- 0.4 g/day; p <0.01), and a hypercatabolic hormonal status (cortisol/insulin ratio 32 +/- 1.7 vs 65 +/- 5.1; p <0.01). We conclude that patients with chronic HF had an inadequate calorie intake to support energetic needs for daily activities, with consequent important protein breakdown that causes muscular wasting
