Research progress of no-reflow phenomenon in interventional treatment of acute ST-segment elevation myocardial infarction
Acute ST-segment elevation myocardial infarction(STEMI)is one of the most dangerous cardiovascular diseases.Percutaneous coronary intervention(PCI)can quickly open the occluded vessels and restore myocardial perfusion,which can significantly reduce the mortality and improve the clinical prognosis of such patients.However,some patients still suffer from impaired myocardial perfusion after opening the occluded vessel,that is,no-reflow(NR)in the coronary artery,which reduces the therapeutic effect and prognosis of patients.This article reviews the definition,diagnosis,related risk factors,prevention and treatment measures of NR,and looks forward to new technologies,aiming to strengthen the attention to NR after PCI in STEMI patients.
