糖尿病(Diabetes Mellitus,DM)是一种严重危害人类健康的慢性病,尤其合并冠心病的糖尿病患者病死率倍增。随着多项研究的开展,对其致病因素、特点、诊断标准以及治疗手段有了深入的了解。血管内超声(intravascularul-trasound,IVUS)能清晰显示血管的组织形态、内膜下各层结构、血管的横断面形态、血管腔内径、动脉壁的厚度,以及动脉粥样硬化斑块的形态、分布、组织学特征等,可提供异常血管壁形态学的详细信息。所以IVUS既能解释介入治疗方法的机制,也可用来选择最佳的介入方法。本文就2型糖尿病合并冠心病患者的发病机制、血管内超声影像特点、支架植入治疗进展作一综述。
Diabetes Mellitus (DM) is a chronic disease that seriously endangers human health. In particular, diabetics with coronary heart disease double the case fatality rate. With the development of a number of studies, it has gained a deep understanding of its causative factors, characteristics, diagnostic criteria and treatment methods. Intravascular ul-trasound (IVUS) can clearly show the morphology of the blood vessels, the structure of the subendocardium, the cross-sectional morphology of the blood vessels, the diameter of the vascular lumen, the thickness of the arterial wall and the morphology of the atherosclerotic plaque. Distribution, histological features, etc., can provide detailed information on abnormal vessel wall morphology. Therefore, IVUS can explain the mechanism of interventional therapy, but also can be used to select the best intervention method. This article reviews the pathogenesis of type 2 diabetes mellitus patients with coronary heart disease, the characteristics of intravascular ultrasound imaging and the progress of stent implantation.
