在排除心肌梗塞后疑似急性冠状动脉综合征 (ACS) 的患者中,HEART评分在识别阻塞性冠状动脉疾病 (CAD) 方面比高灵敏性托罗素I (hsTnI) 更有效.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 诊断的准确性 诊断的准确性
背景情况:
- 怀疑患有急性冠状动脉综合征 (ACS) 但没有心肌梗塞的患者仍然可以患有阻塞性冠状动脉疾病 (CAD).
- 中级高灵敏性托罗邦素I (hsTnI) 度与阻塞性CAD的更高风险有关.
- 计算机断层扫描冠状动脉扫描 (CTCA) 是这些患者潜在的下游调查.
研究的目的:
- 为了比较HEART得分与hsTnI度在识别阻塞性CAD的诊断性能.
- 评估哪种方法更好地为CTCA选择患者.
主要方法:
- 对433名疑似ACS.患者的前性队列的分析.
- 患者的hstnI没有升高,并且接受了CTCA.
- 使用灵敏度,特异性,PPV和NPV进行HEART得分和hsTnI的比较.
主要成果:
- 在27.7%的患者中存在阻塞性CAD.
- 中间的hsTnI和非低风险的HEART得分与阻塞性CAD的更高率有关.
- 与hsTnI相比,HEART得分显示出更高的灵敏度 (89.2%与63.3%) 和NPV (92.4%与81.9%).
结论:
- 与hsTnI相比,HEART得分为在心肌梗塞排除后疑似ACS的患者提供了更好的阻塞性CAD风险分层.
- 使用HEART得分可以提高患者对CTCA的选择,从而导致更准确的诊断.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
