冠状动脉微血管功能障碍的诊断方法研究进展

摘要

Coronary microvascular dysfunction (CMD) is a special type of coronary artery disease. Coronary microvascular cannot be directly imaged by coronary angiography, thus results in difficulty in diagnosing CMD. Nowadays, there are various examinations for coronary microvascular function, including traditional coronary flow reserve test based on interventional examination and non-invasive coronary microcirculation function tests based on X-ray, MRI, ultrasound, and radionuclide imaging. The paper briefly reviews the commonly used methods for diagnosing CMD, application scope, advantages and disadvantages, and assessment situation.%冠状动脉微血管功能障碍是冠心病的一种特殊类型,与冠状动脉大血管不同,微血管不可通过冠状动脉造影直接显像,因而冠状动脉微血管功能障碍的诊断非常困难.目前冠状动脉微血管功能的评估方法多种多样,从传统的基于介入检查的冠状动脉血流储备,到近年来发展出了基于X射线、MRI、超声和放射性核素等影像学技术的新型冠状动脉微循环功能评估指标.现简要综述目前临床常用的冠状动脉微血管功能障碍的诊断方法、适用范围、优点与缺点、评估情况.
