Description
Abstract
Prompt myocardial reperfusion during acute myocardial infarction by fibrinolytic therapy, percutaneous coronary intervention, or coronary artery bypass grafting limits the affected area and improves prognosis. However, reperfusion itself can cause cardiomyocyte damage and decrease treatment efficacy. No treatments that effectively prevent myocardial ischemia/reperfusion (I/R) injury are currently available, and are therefore the focus of ongoing research. Salvianolic acid A (SAA), the active ingredient of the traditional Chinese herbal remedy Salvia miltiorrhiza, has anti-thrombotic activity, anti-inflammatory, and anticancer activity; regulates blood lipids and provides hepatic and neural protection. Recent studies demonstrated that SAA inhibits cardiomyocyte apoptosis in response to I/R by the PI3K/Akt, GSK-3β, JNK, and ERK1/2 pathways, and by JNK-ERK1/2 crosstalk. The mechanisms for SAA attenuating cardiomyocytes apoptosis during I/R injury through the P38 MAPK, caspase, JAK/STAT, NF-κB and LOX-1 signaling pathways need further illustration. There may be potential crosstalks between PI3K/Akt and JNK, and Akt/GSK-3β and ERK1/2 in the process of SAA against I/R-incuced cardiomyocytes apoptosis. This review summarizes the recent evidence of the anti-apoptotic effects and mechanisms of SAA against myocardial I/R injury and discusses the basis of potential clinical applications of SAA.
