某些胸痛患者经冠脉造影发现心外膜冠状动脉未见狭窄,而远端血流灌注延迟,我们把这种现象称之为冠状动脉慢血流现象。这种现象早在37年前就已经发现,但至今为止关于这种现象的发生机制与治疗仍不清楚,且这部分患者有反复发作其他疾病不能解释的胸痛症状,远期发生心肌缺血、急性冠状动脉综合征甚至急性心肌梗死、室性心律失常致猝死的几率增加。本文就近几年关于冠状动脉慢血流的相关研究作一综述。
Some patients with chest pain by coronary angiography found epicardial coronary artery stenosis, and delayed distal perfusion, we call this phenomenon of slow coronary flow phenomenon. This phenomenon has been discovered as early as 37 years ago, but so far the mechanism and treatment of this phenomenon is still not clear, and this part of patients have recurrent symptoms of chest pain can not be explained by other diseases, myocardial ischemia in the long run, Acute coronary syndromes and even acute myocardial infarction, ventricular arrhythmia caused by an increased risk of sudden death. This article in recent years on the coronary artery slow blood flow related research is reviewed.
