摘要冠状动脉钙化积分(coronary artery calcification score,CACS)是独立于传统风险要素的风险分层因素,能够有效评价心血管事件风险.随着健康体检中肺癌筛查项目的进展,受检者在接受低剂量胸部CT平扫肺癌筛查的同时,进行CACS评价及心血管病变危险度分层,有利于加强心血管健康管理.本文主要从冠状动脉钙化的病理基础、钙化积分的意义、低剂量胸部CT平扫评估CACS在心血管事件风险筛查中的价值等方面进行介绍.

abstractsThe coronary artery calcification score(CACS)is used for risk stratification independent of traditional risk factors,and can effectively predict the incidence of cardiovascular events.As part of a lung cancer screening project, subjects undergoing low-dose chest computed tomography (CT) can also be evaluated for the CACS to determine the risk of cardiovascular disease.These measures can help strengthen public health management. This paper focused on the pathological basis of coronary calcification, the significance of the calcification score,and the application and significance of CACS evaluated with low-dose chest CT in cardiovascular risk screening.
