主要方法:
- 涉嫌或确诊患有CAD,并接受连续CCTA的患者被纳入.
- 冠状动脉样硬化进展量化使用冠状动脉分数 (CACS) 和段狭窄分数 (SSS) 的变化.
- 对比了三个风险模型:基线因素,基线因素+SSS和基线因素+SSS+SSS进展.
主要成果:
- 总共有516名患者被跟踪平均65.29个月,其中发生了114名MACE.
- 在MACE组中观察到较高的基线和随访CACS和SSS,以及较大的动脉样硬化进展 (ΔSSS, ΔCACS).
- 与没有它的模型相比,细分狭窄评分 (SSS) 进展显著改善了预后信息 (C指数) 和风险重新分类 (NRI).

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
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...

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
