冠状动脉支架内再狭窄机制研究现状

Mechanisms of Coronary Artery In-stent Restenosis

目前,冠状动脉内支架植入术已广泛应用于临床,成为冠心病常规介入治疗的方法之一,也使冠状动脉内介入治疗后再狭窄的发生率大为降低。但冠脉内安装支架只能降低,并不能完全防止再狭窄的发生,支架内再狭窄仍是影响远期效果的主要因素。从支架内再狭窄的分类、影响因素和发生机制等方面做一综述。

Intracoronary stent implantation has widely applied in clinic recently. It has become one of the interventional methods to treat coronary artery disease. It has also reduced the incidence rate of resteuosis after intracoronary interventional therapy. But stent installing in coronary can only reduce but cannot completely prevent restenosis. In-stent restenosis is still to remain the main factor to influence longterm result. This context is a summary about the classification,the factors and the mechanisms of it.
