Application of bioabsorbable stent in the interventional treatment of coronary heart disease
Percutaneous coronary intervention(PCI)is the preferred treatment for coronary artery disease(CAD).Currently,drug-eluting stents(DES)implanted in the coronary artery remain the primary method of PCI.However,the long-term retention of metallic stents in the vessel increases the risk of chronic inflammation,stent thrombosis,and restenosis.The emergence of bioresorbable scaf-folds(BRS)promises to significantly reduce these risks by allowing the vessels to regain their structure and diastolic function after a certain period of degradation.BRS is currently being widely researched worldwide for its potential application in clinical practice.This review summarizes currently available or developing BRS,detailing their principles and structures,including scaffold materials,thick-nesses,and degradation time,etc.Furthermore,this review analyzes from a clinical perspective the advantages of BRS in coronary in-tervention therapy,such as rapid recovery and fewer complications.Finally,this review compares the effectiveness and safety differ-ences between BRS and traditional metallic stents.BRS offers an easier and safer treatment option for patients with CAD,potentially reducing the rate of adverse events in advanced stages.However,there are still some problems in the practical application of BRS.This paper reviews the clinical application and latest research progress of BRS,with a view to providing directions for the con-tinuous improvement of BRS and its early clinical widespread use.
