Coronary artery disease (CAD) is the primary cause of death in adults in the United States. Only 50% of patients who present with a myocardial infarction have a prior history of CAD. Non-invasive cardiac imaging tests have been developed to diagnose CAD. Current guidelines and systematic reviews have tried to determine the prognostic value of the coronary artery calcium (CAC) scoring and the coronary computed tomography angiography (CCTA) for major adverse cardiovascular events. Several studies support the roles of CCTA and CAC scoring for the diagnosis of CAD in asymptomatic patients. Further studies are needed to confirm the superior role of CCTA over CAC scoring in symptomatic patients.
冠心病（CAD）是美国成年人的主要死亡原因。仅有 50%的心肌梗死患者有 CAD 既往史。现已开发出无创性心脏成像检查来诊断 CAD。目前的指南和系统评价试图确定冠状动脉钙（CAC）评分和冠状动脉计算机断层扫描血管造影（CCTA）对主要不良心血管事件的预后价值。多项研究支持 CCTA 和 CAC 评分在无症状患者 CAD 诊断中的作用。需要进一步的研究来证实 CCTA 在有症状患者中的诊断价值优于 CAC 评分。
