Clinical Trial Summary

Recently, more and more studies have confirmed that intestinal flora is closely related to the occurrence and development of cardiovascular diseases.Bile acids (BAS), short chain fatty acids (SCFA) and trimethylamine oxide (TMAO), the main metabolites of intestinal flora, are the key mediators of the interaction between gut and host. We aim to explore the association of BAs and SCFA with cardiac function in patients with AMI.

Description:

Cardiovascular disease is the leading cause of death in China, and acute myocardial infarction (AMI) is the main cause of death of cardiovascular disease. In recent years, clinical epidemiological studies have confirmed that intestinal flora is closely related to the occurrence and development of cardiovascular diseases such as diabetes, hyperlipidemia, hypertension, atherosclerosis, coronary heart disease, heart failure and so on. Bile acids (BAS), short chain fatty acids (SCFA) and trimethylamine oxide (TMAO), the main metabolites of intestinal flora, are the key mediators of the interaction between gut and host. It is suggested that intestinal flora and its metabolites participate in the pathophysiological process of cardiovascular disease through inflammation, oxidative stress and programmed death, and have the potential to be intervention targets. Basic and clinical studies have shown that TMAO is associated with the onset and poor prognosis of AMI by promoting the development of atherosclerosis and thrombosis, but there are few reports on the relationship between BAs or SCFA and AMI. We aim to explore the association of BAs and SCFA with cardiac function in patients with AMI.
