OBJECTIVES: The goal of this study was to investigate the nutrition adequacy and energy availability for physical activity in free-living, clinically stable patients with chronic heart failure (CHF). BACKGROUND: Little information exists regarding the nutrition adequacy and alimentary habits of patients with clinically stable CHF. We hypothesized that CHF patients have an inadequate intake of calories and protein, leading to a negative calorie and nitrogen balance, an expression of increased tissue breakdown. METHODS: In 57 non-obese patients with CHF (52 males and 5 females; 52 ± 3 years; body mass index 2) and in 49 healthy subjects (39 males and 10 females) matched for age, body mass index, and sedentary life style we evaluated total energy expenditure (TEE), calorie intake kcalI), and nitrogen intake (NI) from a seven-day food diary, total nitrogen excretion (TNE), and energy availability (EA = kcalI - resting energy expenditure). A zero calorie balance (CB) occurred when kcalI = TEE; a nitrogen balance (NB) in equilibrium was set at NB (= NI - TNE) 0 ± 1 g/day. RESULTS: In patients and controls kcalI and NI were similar. However, in CHF patients the kcalI was
