Mice that drank sodium propionate aqueous solution for 15 days (Fig. S3A) had significantly lower plasma Ang II level (Fig. 5A), less myocardial infarct size (Fig. 5B-C), lower plasma CK-MB level and cTn-I level (Fig. 5D-E), higher LVEF and LVFS, and smaller LVESd and LVEDd (Fig. 5F-J) after establishing an myocardial I/R model than mice that drank sterile water or mice that drank sodium chloride aqueous solution. Here, AGT is linked to myocardial infarction.
