Abstract: Coronary heart disease, which commonly threatens human health, refers to coronary atherosclerosis caused by vascular stenosis, obstruction-induced myocardial ischemia, and hypoxic necrosis of heart disease. Various diagnostic methods are available for detecting coronary atherosclerotic plaque formation. However, these strategies exhibit evident limitations. With the development of CT technology, coronary CT angiography has become an important diagnostic and troubleshooting means for easy identification of plaque loss in the prevention and treatment of acute coronary events. This technology offers a positive clinical value.
