Commonly used clinical coronary heart disease examination such as: cardiac ultrasound, cardiac nuclear magnetic resonance imaging, cardiac CT, cardiac isotope myocardial imaging, coronary angiography, IVUS, etc., their spatial resolution are relatively low, and it is worth our attention that the optical coherence tomography (OCT) technology has not only made an outstanding contribution to the diagnosis of coronary heart disease, but has also further demonstrated its uniqueness in the interventional therapy of coronary heart disease, which utilizes the principle that the reflected light from biological tissues at different depths is captured and recorded by interferometers, and then computerized to produce a simple and clear image. Using OCT, we were able to achieve 10-μm resolution of the vessel wall, an advantage that makes it important to understand coronary atherosclerotic lesions, to develop and optimize interventional strategies, to evaluate the effects of stenting, and to follow up in the long term. This article summarizes the current status and future prospects of OCT in the diagnosis and treatment of coronary heart disease.展开更多
