目的探讨16层螺旋CT对冠状动脉斑块诊断的价值。方法35例临床诊断为冠心病患者按危险度分为2组:急性冠状动脉综合征(ACS)组(包括急性心肌梗塞,不稳定型心绞痛)和稳定型心绞痛组。行16层螺旋CT冠状动脉成像及图像后处理,对检出的斑块进行定性分析,并对各种性质斑块所引起的管腔狭窄程度进行分析。结果35例中,ACS组27例,软斑块19个,中间斑块11个,钙化斑块7个;8例稳定型心绞痛组中软斑块3个,中间斑块3个,钙化斑块11个,经统计学卡方检验P<0.05有统计学意义,表明中间斑块和软斑块(尤其是软斑块)与冠心病危险性程度成显著的正相关;非钙化斑块导致管腔狭窄程度:轻度狭窄8处,中度狭窄9处,重度狭窄22处,而钙化斑块:轻度狭窄10处,中度狭窄5处,重度狭窄5处,经统计学卡方检验P<0.05有统计学意义,表明不同性质斑块与其导致管腔狭窄间有显著差别。结论16层螺旋CT冠状动脉造影成像是一种有效、无创、简便、优良的诊断方法,可作为诊断冠心病的可靠手段用于临床。
Objective To investigate the value of 16-slice spiral CT in the diagnosis of coronary artery plaque. Methods 35 cases of clinical diagnosis of coronary heart disease according to the risk of patients were divided into two groups: acute coronary syndrome (ACS) group (including acute myocardial infarction, unstable angina) and stable angina group. 16-slice spiral CT coronary angiography and image post-processing, the qualitative analysis of the detected plaques, and various plaques caused by the degree of stenosis were analyzed. Results Among the 35 cases, there were 27 cases of ACS, 19 soft plaques, 11 middle plaques and 7 calcified plaques. Among the 8 cases of stable angina pectoris, 3 soft plaques, 3 middle plaques, 11 calcified plaques P <0.05 by statistical chi-square test was statistically significant, indicating that the middle plaque and soft plaque (especially soft plaque) and coronary heart disease risk level was significantly positively correlated; non-calcified plaque led to the lumen Stenosis: mild stenosis in 8, moderate stenosis in 9, 22 severe stenosis, and calcified plaque: 10 mild stenosis, 5 moderate stenosis, 5 severe stenosis, the statistical Chi-square test P < 0.05 was statistically significant, indicating that there are significant differences between the different nature of the plaque and its lead to stenosis. Conclusion 16-slice spiral CT coronary angiography is an effective, noninvasive, simple and excellent diagnostic method, which can be used as a reliable method to diagnose coronary heart disease in clinical practice.
