尽管多种无创性冠脉影像诊断方法以及冠脉造影已经成为现代冠心病诊疗的重要手段,但是在决定冠脉临界病变程度、是否需要进行介入治疗、以及早期识别易损斑块和准确评价支架植入即刻和远期效果等方面仍然存在很多困难与争议。血管内光学干涉断层成像在管腔狭窄程度、范围以及斑块性质的显示方面有不可比拟的优势,其组织分辨率大约较IVUS高10倍,近似病理组织学程度,但是其在老年冠心病人中的应用极少。本文综述冠脉临界病变的影像诊断进展,以有助于危险评估、治疗决策,最终促进介入治疗的合理应用。
Although a variety of non-invasive diagnostic methods of coronary arteries and coronary angiography have become an important means of modern coronary heart disease diagnosis and treatment, but in determining the severity of coronary lesions, the need for interventional treatment, as well as early detection of vulnerable plaque and accurate assessment of stent Implantation of immediate and long-term effects and so there are still many difficulties and controversies. Intravascular optical interference tomography has unparalleled advantages in the display of extent, range and plaque quality of luminal stenosis, and its tissue resolution is about 10 times higher than that of IVUS, which is similar to the degree of histopathology. However, in the elderly patients with coronary artery disease Very few applications. This review summarizes the advances in imaging diagnosis of critical coronary lesions to aid in the assessment of risk, treatment decisions, and ultimately the rational use of interventional therapy.
