Key result
Although 75% of heart failure patients reported following a low-sodium diet, 24-hour urine sodium excretion revealed that only 25% were actually adherent.

What is the relationship between heart failure patients' knowledge, perceived barriers, and attitudes regarding low-sodium diet recommendations and their actual dietary adherence?
Heart failure patients significantly overestimate their adherence to low-sodium diets, highlighting a major gap between perceived compliance and actual sodium intake.
Lennie et al. (2008) conducted a cross-sectional in Heart failure (n=246). Low-sodium diet recommendations was evaluated on Adherence to low-sodium diet based on 24-hour urine sodium excretion. Although 75% of heart failure patients reported following a low-sodium diet, 24-hour urine sodium excretion revealed that only 25% were actually adherent.
