Research Progress on the Mechanism of Coronary Artery Slow Blood Flow Phenomenon and Drug Therapy
The phenomenon of slow coronary flow(SCF)refers to the slow passage of contrast agent and delayed per-fusion of the distal coronary artery observed in some patients with chest pain undergoing selective coronary angiogra-phy without obvious stenosis.To distinguish it from"X syndrome",the SCF phenomenon is also known as"Y syn-drome".Since its discovery,different hypotheses have been proposed and validated regarding the etiology and risk fac-tors of slow blood flow phenomenon.Currently,it has been found that it may be related to endothelial dysfunction,in-flammatory response,abnormal blood cells and platelets,genetic factors,etc.In terms of treatment,the main focus is on improving microvascular function,anti-inflammatory effects,and maintaining vascular endocrine function.This ar-ticle will review the mechanism of slow blood flow phenomenon and the research progress of drug treatment in recent years,in order to promote the clinical diagnosis and treatment of slow blood flow phenomenon and improve the quality of life of patients.
