Overview of the possible mechanism of IBA affecting MACE in patients with coronary heart disease. This figure details a summary of the possible mechanism that IBA can increase the incidence of MACE in CHD patients by influencing the metabolism of TRP by C. sporogenes to produce IPA and 5-HIAA. TRP, tryptophan; IBA, indole-3-butyric acid; IPA, indole-3-propionic acid; 5-HIAA, 5-hydroxyindole-3-acetic acid; C. sporogenes, Clostridium sporogenes; MACE, major adverse cardiovascular events; CHD, coronary heart disease.
