Abstract:

Interventional therapy of coronary heart disease (CHD) includes percutaneous transluminal coronary angioplasty (PTCA), stent implantation etc. Owing to its revascularization without cardiac surgery, it has been the main effective method in treating CHD. But at the same time, there exists the problem of restenosis (RS). After PTCA, RS rate can reach 30% to 50%, even with direct stenting into the vessels, it still reaches 20% to 35%. So this affects long-term effect of interventional therapy, which directly relates to prognosis of patients with CHD and has been a hot spot of study in the field of preventing and treating CHD.
