To determine whether coronary computed tomography angiography (CCTA) can improve the diagnostic work-up of patients with acute chest pain and inconclusively high-sensitivity troponins (hs-troponin).
We conducted a prospective, blinded, observational, multicentre study. Patients aged 30-80 years presenting to the emergency department with acute chest pain and inconclusively elevated hs-troponins were included and underwent CCTA. The primary outcome was the diagnostic accuracy of ≥ 50% stenosis on CCTA to identify patients with type-1 non-ST-segment elevation acute coronary syndrome (NSTE-ACS).
A total of 106 patients (mean age 65 ± 10, 29% women) were enrolled of whom 20 patients (19%) had an adjudicated diagnosis of type-1 NSTE-ACS. In 45 patients, CCTA revealed non-obstructive coronary artery disease (CAD) or no CAD. Sensitivity, specificity, negative predictive value (NPV), positive predictive value and area-under-the-curve (AUC) of ≥ 50% stenosis on CCTA to identify patients with type 1 NSTE-ACS, was 95% (95% confidence interval: 74-100), 56% (45-68), 98% (87-100), 35% (29-41) and 0.83 (0.73-0.94), respectively. When only coronary segments with a diameter ≥ 2 mm were considered for the adjudication of type 1 NSTE-ACS, the sensitivity and NPV increased to 100%. In 8 patients, CCTA enabled the detection of clinically relevant non-coronary findings.
The absence of ≥ 50% coronary artery stenosis on CCTA can be used to rule out type 1 NSTE-ACS in acute chest pain patients with inconclusively elevated hs-troponins. Additionally, CCTA can help improve the diagnostic work-up by detecting other relevant conditions that cause acute chest pain and inconclusively elevated hs-troponins.
Coronary CTA (CCTA) can safely rule out type 1 non-ST-segment elevation acute coronary syndrome (NSTE-ACS) in patients presenting to the ED with acute chest pain and inconclusively elevated hs-troponins, while also detecting other relevant non-coronary conditions.
Clinicaltrials.gov (NCT03129659). Registered on 26 April 2017 KEY POINTS: Acute chest discomfort is a common presenting complaint in the emergency department. CCTA achieved very high negative predictive values for type 1 NSTE-ACS in this population. CCTA can serve as an adjunct for evaluating equivocal ACS and evaluates for other pathology.
确定冠状动脉计算机断层扫描血管造影（CCTA）能否改善急性胸痛且高敏肌钙蛋白（hs - 肌钙蛋白）结果不明确患者的诊断检查。
我们开展了一项前瞻性、盲法、观察性、多中心研究。纳入年龄在30 - 80岁、因急性胸痛到急诊科就诊且hs - 肌钙蛋白升高但结果不明确的患者，并进行CCTA检查。主要结局是CCTA上≥50%狭窄对识别1型非ST段抬高型急性冠状动脉综合征（NSTE - ACS）患者的诊断准确性。
共纳入106例患者（平均年龄65±10岁，29%为女性），其中20例患者（19%）经判定诊断为1型NSTE - ACS。45例患者的CCTA显示非阻塞性冠状动脉疾病（CAD）或无CAD。CCTA上≥50%狭窄对识别1型NSTE - ACS患者的敏感性、特异性、阴性预测值（NPV）、阳性预测值和曲线下面积（AUC）分别为95%（95%置信区间：74 - 100）、56%（45 - 68）、98%（87 - 100）、35%（29 - 41）和0.83（0.73 - 0.94）。当仅考虑直径≥2mm的冠状动脉节段来判定1型NSTE - ACS时，敏感性和NPV增至100%。8例患者中，CCTA能够检测到临床相关的非冠状动脉病变。
CCTA上无≥50%冠状动脉狭窄可用于排除hs - 肌钙蛋白升高但结果不明确的急性胸痛患者的1型NSTE - ACS。此外，CCTA可通过检测导致急性胸痛和hs - 肌钙蛋白升高但结果不明确的其他相关疾病，帮助改善诊断检查。
冠状动脉CT血管造影（CCTA）可安全地排除因急性胸痛到急诊科就诊且hs - 肌钙蛋白升高但结果不明确患者的1型非ST段抬高型急性冠状动脉综合征（NSTE - ACS），同时还能检测其他相关的非冠状动脉疾病。
Clinicaltrials.gov（NCT03129659）。于2017年4月26日注册 关键点：急性胸痛是急诊科常见的就诊主诉。CCTA在该人群中对1型NSTE - ACS具有非常高的阴性预测值。CCTA可作为评估可疑ACS的辅助手段，并评估其他病变。
