近年来冠心病发病率和死亡率呈逐年上升趋势,随着经皮冠状动脉介入治疗的普及和冠脉慢血流现象的认识,心肌微循环障碍日益受到临床医生的关注。目前评估心肌微循环障碍的方法主要有冠状动脉血流储备分数、心肌声学造影、心肌磁共振成像及冠脉微循环阻力指数(IMR),但上述方法各有一定的局限性,部分指标特异性及敏感性有待于询证医学的进一步验证,本文对心肌微循环障碍的评估方法及研究进展做一综述。
In recent years, the morbidity and mortality of coronary heart disease have been increasing year by year. With the popularity of percutaneous coronary intervention and the understanding of slow blood flow of coronary arteries, the microcirculation disturbance of the myocardium has been paid more and more attention by clinicians. Current methods for assessing myocardial microcirculation disorders include coronary flow reserve, myocardial contrast echocardiography, myocardial magnetic resonance imaging, and coronary microcirculation resistance index (IMR), but each of these methods has its own limitations, some of which are specific And sensitivity to be further verified by inquiry medicine, this article reviews the evaluation methods and research progress of myocardial microcirculation disorders.
