Research progress on coronary slow flow or no-reflow of coronary heart disease undergoing percutaneous coronary intervention surgery
Coronary heart disease(CHD),a prevalent cardiovascular disorder,poses a significant threat to human health.Particularly,ST-segment elevation myocardial infarction(STEMI)is associated with a higher mortality rate.Timely and effec-tive revascularization of the culprit vessels is crucial.Percutaneous coronary intervention(PCI)is a preferred and critical treatment mo-dality for STEMI patients,effectively addressing vascular obstruction.However,a subset of patients experiences coronary slow flow(CSF)or no-reflow(NR)postoperatively,which severely impacts their prognosis.This article provides a comprehensive review of the definition,diagnosis,epidemiology,predictive factors,mechanisms,and treatment of CSF/NR,aiming to offer guidance for the clini-cal management of these complications following PCI in CHD patients.
