Insufficient RCT data on salt restriction in HF; leaves open effects on outcomes and current recommendations.
Systematic Review (n=479)
Does reduced dietary salt intake improve clinical outcomes in adult inpatients or outpatients with heart failure?
There is currently a lack of robust, high-quality evidence to support or refute the routine recommendation of dietary salt restriction in patients with heart failure.
Mahtani et al. (2018) conducted a systematic review in Heart failure (n=479). Reduced dietary salt intake was evaluated on Cardiovascular-associated mortality, all-cause mortality, and adverse events (such as stroke and myocardial infarction). Reduced dietary salt intake in heart failure patients lacked sufficient data to determine effects on mortality or adverse events, with inconclusive evidence for clinical improvement.
