The Clinical Application of Optical Coherence Tomography (OCT) in Interventional Therapy of Coronary Heart Disease (CHD)

近年来，冠心病的患病人数在我国不断上升，对我国人民的生命财产安全造成了巨大危害。经皮冠状动脉介入治疗(PCI)术在缓解心绞痛症状、改善心肌血运重建等方面发挥了重要作用。光学相干断层成像(OCT)以其高达10 μm的分辨率在指导PCI治疗过程中得到了广泛的应用，其不仅可以精准地评估病变斑块的性质、成分和病变部位，还能够通过测量血管管腔的直径、病变长度等指导支架尺寸的选择和着陆点的确定，此外还可以用于支架植入后的优化。In recent years, the number of patients with coronary heart disease has been continuously increasing in China, causing huge harm to the life and property safety of the Chinese people. Percutaneous coronary intervention (PCI) has played an important role in relieving angina pectoris symptoms and improving myocardial revascularization. Optical coherence tomography (OCT), with its resolution as high as 10 μm, has been widely used in guiding the PCI treatment process. It can not only accurately determine the nature, composition and location of the lesion plaque, but also guide the selection of stent size and the determination of the landing point by measuring the diameter of the vascular lumen and the length of the lesion. In addition, it can also be used for optimization after stent implantation.
