Abstract
BackgroundHeart failure poses a significant health concern globally, and despite advancements in treatment, the search for additional, supportive therapeutic options remains crucial. This systematic review and meta-analysis studied the impact of probiotics and polyphenols on heart failure biomarkers, focusing on potential improvements in heart function and inflammation.MethodsWe analyzed studies published in Embase, PubMed and Cochrane library from 2012 to 2024, focusing on randomized controlled trials. Our findings are drawn from 5 studies on probiotics, involving 401 participants, and 3 studies on polyphenols with a total of 140 participants. The analysis included assessments of LVEF, hs-CRP, creatinine and NT-proBNP levels in intervention and control groups.ResultsThe probiotics or polyphenols from the included studies did not demonstrate significant changes in the health indicators analyzed for heart failure patients compared to placebo.ConclusionsThe systematic review suggested that while the concept of dietary management for heart failure is promising, further research is necessary to validate the efficacy of probiotics and polyphenols as supplementary therapies in heart failure care, by analyzing more diverse health outcomes and patient populations.
