Analysis of the application value of multi-slice spiral CT in the diagnosis of coronary heart disease

目的分析冠心病诊断中多层螺旋CT(multisliecs helieal CT,MSCT)的应用价值。方法选取2018年6月至2019年6月就诊于本院的230例疑似冠心病患者,均行MSCT检查和冠状动脉造影(coronary angigraphy,CAG)检查。以CAG结果为金标准,计算MSCT诊断的准确度、灵敏度、特异性、符合率,并比较CAG、MSCT两种检查方法对冠状动脉狭窄程度的诊断情况。结果230例疑似冠心病患者中,CAG确诊200例,MSCT确诊195例,以CAG为诊断金标准,MSCT诊断的准确度85.65%,灵敏度90.50%,特异性53.33%,总符合率为97.50%。CAG、MSCT两种检查方法对冠状动脉狭窄程度的诊断结果比较差异无统计学意义。结论MSCT检查冠心病的准确度、灵敏度以及分型符合率较高,可准确反映冠状动脉的狭窄情况,为冠心病的确诊提供重要依据。

Objective To analyze the application value of multisliecs helieal CT(MSCT)in the diagnosis of coronary heart disease.Methods 230 patients with suspected coronary heart disease who were admitted to our hospital from June 2018 to June 2019 were selected for MSCT and coronary angiography(CAG).Using CAG results as the gold standard,calculate the accuracy,sensitivity,specificity,and coincidence rate of MSCT diagnosis,and compare the diagnosis of coronary artery stenosis by CAG and MSCT.Results Among 230 suspected coronary heart disease patients,200 cases were diagnosed by CAG and 195 cases were diagnosed by MSCT.With CAG as the diagnostic gold standard,the accuracy of MSCT diagnosis was 85.65%,the sensitivity was 90.50%,the specificity was 53.33%,and the total coincidence rate was 97.50%.There was no statistically significant difference in the diagnosis of coronary artery stenosis between CAG and MSCT.Conclusion MSCT has a high accuracy,sensitivity and coincidence rate for coronary heart disease.It can accurately reflect the stenosis of coronary arteries and provide an important basis for the diagnosis of coronary heart disease.
