The Role Played by Imidazole Propionic Acid in Modulating Gut-Heart Axis and the Development of Atherosclerosis: An Explorative Review
Abstract
Recent studies have demonstrated the significant role of the normal human microbial component, also known as gut microbiome/gut microbiota (GM). Dysbiosis, or imbalance of GM, can predispose to systemic diseases, including cardiovascular disease (CVD). The GMs' influence extends further to cardiometabolic health, with microbial metabolites playing a pivotal role in these interactions. Traditional risk factors like hyperlipidemia and hypertension are now complemented by emerging evidence implicating GM-derived metabolites in the pathogenesis of atherosclerosis (ATS). Imidazole propionic acid (ImP), a metabolite of histidine derived from GM, has emerged as a significant mediator linking GM dysbiosis to ATS and CVD, or coronary artery disease (CAD). This comprehensive review synthesizes current knowledge on ImP's biosynthesis, molecular mechanisms, clinical relevance, and therapeutic potential, emphasizing its role in the gut-heart axis and cardiovascular pathology. Appropriate keywords, including "microbes", "dysbiosis", "gut microbiota/gut microbiome and cardiovascular disorders", "atherosclerosis and microbes", and "microbial metabolites", among others, were used to extract relevant studies in PubMed and Google Scholar from inception to date. ImP bridges microbial dysbiosis and CVD through endothelial dysfunction, inflammation, and metabolic disturbances. Its production is modifiable by diet and GM composition, positioning ImP as both a biomarker and therapeutic target in…
