冠状动脉CT血管造影综合评估易损斑块的进展

急性冠状动脉综合征（ACS）是以冠状动脉粥样硬化斑块破裂或侵袭，继发完全或不完全闭塞性血栓形成为病理基础的一组临床综合征。与稳定斑块相比，容易破裂的斑块具有明显的影像学特征：大斑块体积，低衰减斑块，餐巾指环标志，正性重构和点状钙化，这为在导致临床事件之前运用非侵入性成像识别易损斑块提供了独特的机会。随着影像技术的发展，冠状动脉CT 血管造影（CCTA）无创性评价冠状动脉易损斑块的作用已成为国内外研究热点。笔者就CCTA在评估冠状动脉斑块易损性方面的临床应用现状与进展等方面作一综述。

Coronary artery CT angiography comprehensive assessment of vulnerable plaque progress

Acute Coronary Syndrome (ACS) is a group of clinical syndromes that are pathologically based on the rupture or invasion of coronary atherosclerotic plaques and secondary to complete or incomplete occlusive thrombosis. Compared with stable plaques, plaques that are easily broken have obvious imaging features: large plaque volume, low attenuation plaques, napkin ring markers, positive remodeling, and punctate calcifications, which are used before leading to clinical events. Non-invasive imaging offers a unique opportunity to identify vulnerable plaque. With the development of imaging technology, the non-invasive evaluation of coronary vulnerable plaques by coronary artery CT angiography (CCTA) has become a research hotspot at home and abroad. The author reviewed the current status and progress of clinical application of CCTA in assessing coronary plaque vulnerability.
