Abstract:
Percutaneous transluminal coronary angioplasty (PTCA) has become one of the most important treatment method in coronary artery disease along with coronary bypass operation and medicine in recent years.Restenosis after intervention becomes the Achili's heel in our daily treatment.In some degree stenting can reduce restenosis,but the restenosis after stenting is still over 20%.The focus of the treatment of restenosis over the last 2 decades has been through the application of pharmacologically active agents and mechanical approaches using a host of different devices.But this frequent and costly complication of percutaneous revascularization techniques has proved refractory to all such therapies.This review will focus on the studies that have been done during recent years,it will cover the mechanism of restenosis after PTCA and stenting,the risk factors involved in the restenosis,and the prevention and treatment of restenosis.
