Nutritional Interventions in Heart Failure: Challenges and Opportunities

There is a growing body of evidence that nutritional factors influence the incidence of heart failure (HF). The current manuscript aims to collate evidence relating to nutritional intervention in the treatment of HF as well as to provide context regarding challenges and opportunities in the field.

Despite the accepted importance of nutritional factors relating to cardiovascular disease severity, there is surprisingly little human intervention research regarding dietary intake and HF. Further, existing nutritional interventions in HF were mostly pilot studies with small samples and short follow-up. There is consistent evidence that nutritional factors majorly influence HF. Despite limited research, there is evidence that nutritional modification can rapidly and profoundly influence multiple aspects of HF. There is an urgent need for well-conducted research to ascertain if nutritional modification can alter the long-term course of HF.
