In the diagnosis of obstructive coronary artery disease (CAD), computed tomography (CT) is an accurate, noninvasive alternative to invasive coronary angiography (ICA). However, the comparative effectiveness of CT and ICA in the management of CAD to reduce the frequency of major adverse cardiovascular events is uncertain.
We conducted a pragmatic, randomized trial comparing CT with ICA as initial diagnostic imaging strategies for guiding the treatment of patients with stable chest pain who had an intermediate pretest probability of obstructive CAD and were referred for ICA at one of 26 European centers. The primary outcome was major adverse cardiovascular events (cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke) over 3.5 years. Key secondary outcomes were procedure-related complications and angina pectoris.
Among 3561 patients (56.2% of whom were women), follow-up was complete for 3523 (98.9%). Major adverse cardiovascular events occurred in 38 of 1808 patients (2.1%) in the CT group and in 52 of 1753 (3.0%) in the ICA group (hazard ratio, 0.70; 95% confidence interval [CI], 0.46 to 1.07; P = 0.10). Major procedure-related complications occurred in 9 patients (0.5%) in the CT group and in 33 (1.9%) in the ICA group (hazard ratio, 0.26; 95% CI, 0.13 to 0.55). Angina during the final 4 weeks of follow-up was reported in 8.8% of the patients in the CT group and in 7.5% of those in the ICA group (odds ratio, 1.17; 95% CI, 0.92 to 1.48).
Among patients referred for ICA because of stable chest pain and intermediate pretest probability of CAD, the risk of major adverse cardiovascular events was similar in the CT group and the ICA group. The frequency of major procedure-related complications was lower with an initial CT strategy.

在阻塞性冠状动脉疾病（CAD）的诊断中，计算机断层扫描（CT）是侵入性冠状动脉造影（ICA）的一种准确、非侵入性替代方法。然而，CT和ICA在CAD管理中降低主要不良心血管事件发生率方面的比较效果尚不确定。
我们进行了一项实用的随机试验，比较CT与ICA作为初始诊断成像策略，以指导患有稳定胸痛且阻塞性CAD预测试验概率为中等并被转诊至26个欧洲中心之一进行ICA的患者的治疗。主要结局是3.5年内的主要不良心血管事件（心血管死亡、非致命性心肌梗死或非致命性中风）。关键次要结局是与手术相关的并发症和心绞痛。
在3561例患者中（56.2%为女性），3523例（98.9%）完成随访。CT组1808例患者中有38例（2.1%）发生主要不良心血管事件，ICA组1753例中有52例（3.0%）发生（风险比，0.70；95%置信区间[CI]，0.46至1.07；P = 0.10）。CT组9例患者（0.5%）发生主要手术相关并发症，ICA组33例（1.9%）发生（风险比，0.26；95%CI，0.13至0.55）。CT组8.8%的患者和ICA组7.5%的患者报告在随访最后4周内心绞痛（比值比，1.17；95%CI，0.92至1.48）。
在因稳定胸痛和CAD预测试验概率中等而转诊进行ICA的患者中，CT组和ICA组主要不良心血管事件的风险相似。初始CT策略时主要手术相关并发症的发生率较低。（由欧盟第七框架计划及其他机构资助；DISCHARGE临床试验注册号，NCT02400229。）
