Non-invasive imaging plays a critical role in the assessment of patients presenting with suspected angina chest pain. However, wide variations in practice across Europe and North America highlight the lack of consensus in selecting the appropriate first-line test for the investigation of coronary artery disease (CAD). CT coronary angiography (CTCA) has a high negative predictive value for excluding the presence of CAD. As such, it serves as a potential 'gatekeeper' to downstream testing by reducing the rate of inappropriate invasive coronary angiography. Two recent large multicentre randomised control trials have provided insights into whether CTCA can be incorporated into chest pain care pathways to improve risk stratification of CAD. They demonstrate that using CTCA enhances diagnostic certainty and improves the targeting of appropriate invasive investigations and therapeutic interventions. Importantly, reductions in cardiac death and non-fatal myocardial infarction appear to be attained through the more appropriate use of preventative therapy and coronary revascularisation when guided by CTCA. With this increasing portfolio of evidence, CTCA should be considered the non-invasive investigation of choice in the evaluation of patients with suspected angina pectoris due to coronary heart disease.

无创成像在评估疑似心绞痛胸痛患者中起着关键作用。然而,欧洲和北美的实践差异很大,这突出表明在选择用于冠状动脉疾病(CAD)调查的合适一线检查方面缺乏共识。CT冠状动脉造影(CTCA)在排除CAD存在方面具有较高的阴性预测价值。因此,它通过降低不适当的有创冠状动脉造影率,成为下游检查的潜在“把关者”。最近两项大型多中心随机对照试验为CTCA是否可纳入胸痛护理路径以改善CAD风险分层提供了见解。它们表明,使用CTCA可提高诊断确定性,并改善适当有创检查和治疗干预的针对性。重要的是,在CTCA的指导下,通过更恰当地使用预防性治疗和冠状动脉血运重建,似乎可以降低心源性死亡和非致命性心肌梗死的发生率。随着这一证据组合的不断增加,在评估因冠心病疑似心绞痛的患者时,CTCA应被视为首选的无创检查。
