心血管疾病是临床上最为常见的一种疾病,发病率极高。大部分心血管病患者都是死于冠心病,心脏性猝死及急性心肌梗死都是导致患者病死率不断提高的主要因素,大多数患者在急性冠状动脉综合征发作前均无任何不良反应或警示征兆。怎样利用心血管影像来确认患者是否处在急性冠状动脉事件的边缘,也成为最近几年的研究热点。通常情况下发生的急性冠状动脉事件都是因为斑块破裂,致使突发管腔内部血栓急剧形成所引起的。极易破裂的冠状动脉病变斑块在形态方面同稳定型斑块完全不同,据此能够在初期运用无创的影像学检查方法对易损斑块进行鉴别。

摘要: 冠心病是由冠状动脉粥样硬化所引起的血管管腔狭窄及阻塞而诱发的缺氧性坏死与心肌缺血的心脏疾病,该疾病的发病率极高。对于冠状动脉粥样硬化斑块形成引发的冠心病有着多种诊断方法,但均存在明显局限性。伴随着CT技术的不断发展,冠状动脉CT血管成像成为关键的诊断与排查方法,对于易损斑块的识别和急性冠状动脉事件的防治具有较高的临床价值。

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. -
