NEJM:稳定型胸痛患者CT或有创冠状动脉造影的比较

2022-04-28 MedSci原创 MedSci原创

对于稳定型胸痛和中等的阻塞性冠状动脉疾病预测概率而接受ICA的患者,CT组和ICA组发生主要不良心血管事件的风险相似。采用CT诊断策略时,主要手术相关并发症的发生率较低。

在阻塞性冠状动脉疾病的诊断中,计算机断层扫描(CT)是一种精确的、无创手段,相比于有创的冠状动脉造影(ICA)。然而,CT和ICA在冠心病诊断和治疗过程中对于降低主要不良血管事件发生频率的相对有效性尚未明确。

近日,顶级医学期刊NEJM上发表了一篇研究文章,研究人员进行了一项实用的随机试验,以比较CT和ICA作为初始诊断影像策略,以指导转诊到26个欧洲中心之一进行ICA的阻塞性冠状动脉疾病的稳定型胸痛患者。该研究的主要结局为3.5年的主要不良心血管事件(心血管死亡、非致死性心肌梗死或非致死性卒中),主要的次要结局是手术相关并发症和心绞痛。

在3561例患者(56.2%为女性)中,有3523例(98.9%)完成了随访。1808例CT组患者中有38例(2.1%)发生主要不良心血管事件,1753例ICA组患者中有52例(3.0%)发生主要不良心血管事件(风险比为0.70;95%置信区间[CI]为0.46~1.07;P = 0.10)。

进一步研究发现,CT组有9例(0.5%)发生重大手术相关并发症,ICA组有33例(1.9%)发生重大手术相关并发症(风险比为0.26;95%CI为0.13~0.55)。在随访的最后4周,8.8%的CT组患者发生心绞痛,7.5%的ICA组患者发生心绞痛(比值比为1.17;95%CI为0.92~1.48)。

由此可见,对于稳定型胸痛和中等的阻塞性冠状动脉疾病预测概率而接受ICA的患者,CT组和ICA组发生主要不良心血管事件的风险相似。采用CT诊断策略时,主要手术相关并发症的发生率较低。
