64层螺旋CT评价冠状动脉斑块稳定性的临床价值(1)
【摘要】 目的：探究64层螺旋CT对冠状动脉斑块稳定性评价的可行性与准确性。方法：选取2015年1月至2017年2月笔者所在医院收治的184例采用CT冠状动脉成像诊断的冠心病患者作为研究对象，根据患者的临床资料将其分成对照组和研究组，对照组患者为急性冠状动脉综合征(89例)，研究组患者为稳定性心绞痛(95例)，比较两组患者的斑块数量、形态、CT值及正向重构情况。结果：两组患者共检测出375个斑块，对照组检出180个斑块，研究组检出195个斑块；研究组Ⅰ型斑块占比明显高于对照组，Ⅱ型、Ⅲ型斑块占比明显低于对照组，研究组患者的致病斑块CT值为(67.9±28.7)HU，明显高于对照组的(29.4±22.5)HU，研究組患者的正向重构率为24.6%，明显低于对照组的57.2%，比较差异均有统计学意义(P<0.05)；两组患者的致病斑块数量占比比较差异无统计学意义(P>0.05)。结论：对冠心病患者采用CT扫描识别斑块形态和测量斑块密度，能有效鉴别斑块的稳定性，有助于为临床提供诊疗的依据。

【Abstract】 Objective：To investigate the feasibility and accuracy of 64-slice spiral CT in evaluating the stability of coronary plaque.Method：From January 2015 to February 2017，184 patients with coronary heart disease diagnosed by CT coronary angiography were selected as the study subjects，and were divided into control group and study group according to the clinical data of the patients.Patients in the control group were acute coronary syndrome(89 cases)，patients in the study group were stable angina(95 cases).The number of plaque，morphology，CT value and positive reconstruction of the two groups were compared.Result：A total of 375 plaques were detected，180 plaques were detected in the control group，195 plaques were detected in the study group.The ratio of type I plaque in the study group was significantly higher than that in the control group；the ratio of type Ⅱ and type Ⅲ plaques was significantly lower than that of the control group；the CT value of the diseased plaque in the study group was (67.9±28.7)HU，which was significantly higher than that of the control group[(29.4±22.5)HU]；the positive reconstruction rate of the study group was 24.6%，which was significantly lower than that of the control group(57.2%)，and the differences were statistically significant(P<0.05).There was no significant difference between the two groups in the number of plaque(P>0.05).Conclusion：CT scan can identify plaque morphology and measure plaque density in patients with coronary heart disease，which can effectively identify the plaque stability.Therefore，it is helpful to provide basis for clinical diagnosis and treatment.
