Abstract: Salvianolic acids are the main water-soluble active compounds of Salvia miltiorrhiza and have been widely used for the treatment of cardiovascular diseases. Based on the latest studies in China and abroad, we summarize the pharmacological effects and mechanism of salvianolic acids on ischemic heart disease by describing how salvianolic acid A and salvianolic acid B protect the vascular endothelium, relax coronary arteries, promote angiogenesis and anti-platelet aggregation, inhibit the inflammatory response, anti-cell apoptosis, and scavenge free radicals. This review provides a theoretical basis for further research on the effects of salvianolic acids on ischemic heart disease and their potential for drug development.
