Cardiovascular diseases (CVD) are one of the leading causes of death worldwide. Genetic factors, and various environmental factors, including nutrition and the composition of the gut microbiota, have been identified as important factors in the initiation of CVD. Among them, the pivotal role of the gut microbiota in modulating cholesterol metabolism and influencing cardiovascular outcomes has recently been highlighted. Extensive research has confirmed that the gut microbiota has direct and indirect regulatory effects on host cholesterol homeostasis. Recent studies have shown that the microbiota can influence blood cholesterol levels and thus the risk of CVD through various pathways, such as the production of certain metabolites such as bile acids (BAs), SCFAs, and TMAO, the activation of nuclear and membrane-bound receptors such as farnesoid X receptor (FXR), the regulation of gene expression involved in lipid metabolism and inflammatory responses, as well as microbial enzymatic pathways. These complex regulatory mechanisms make the gut microbiota a potential therapeutic target in cholesterol-related diseases and CVD. Microbiota-modulating strategies, including the use of probiotics, prebiotics, fecal microbiota transplantation (FMT), and selective antibiotics, have shown beneficial effects in previous studies. In this regard, in this study, we conducted an in-depth investigation of the regulatory effect of intestinal microbiota on cholesterol metabolism and their impact on the development and progression of atherosclerosis and CVD, and described potential therapeutic pathways based on the regulation of intestinal microbiota in CVD.
