中文摘要：

随着当前冠状动脉造影的普及，临床上发现的冠状动脉慢血流（CSF）患者并不少见，患者常以发作性胸痛为主要临床表现。CSF可能是系统性血管紊乱的一部分，可能会引起严重的心血管事件，甚至有猝死的风险。其在心绞痛患者中的发生率占相当部分比例。因此，CSF越来越受到关注，但其发病机制目前尚不明确，CSF发病可能是多种混杂因素共同作用的结果。

英文摘要：

With the popularity of coronary angiography, clinical findings on coronary slow flow （CSF） of patients is not uncommon, and the main clinical manifestation is usually the episode of chest pain. CSF may be part of a systemic vascular disorder,and may cause serious cardiovascular events,and even sudden death. The incidence among angina patients accounts for a considerable part. Therefore ,CSF has become a growing concern, though its pathogenesis is unclear,studies suggest that CSF may be the result of many confounding factors working together.
