ABSTRACT
Sphingosine-1-phosphate (SIP) is an important bio- active phospholipid molecule, which is involved in the occurrence and development of cardiovascular diseases such as atherosclerosis, myocardial ischemia and reperfusion injury, myocardial infarction, myocardial fibrosis and myocardial remodeling, and it plays a wide range of biological effects in human cardiovascular system.SIP acts mainly in the form of binding of sphingosine-1-phosphate receptor (SI Pits), selectively binding vascular endothelial cells and smooth muscle cells, which plays a role in the fight against cardiovascular diseases.This paper reviews the biological effects of SIP in cardiovascular system, i- dentifies effective targets in cardiovascular diseases, and alleviates the damage caused by SI P.aiming to provide new ideas for the study of SIP in cardiovascular direction.
