- 冠状动脉旁路移植 (CABG) 仍然是严重冠状动脉疾病的基石治疗方法.
- 早期检测绕道移植的闭塞对于患者的治疗结果至关重要.
- 心脏计算机断层扫描血管造影 (CCTA) 提供了绕道移植的详细可视化.
研究的目的:
- 为了确定CABG后早期无声绕道移植封闭的发生率.

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...
