冠状动脉钙化63例CT诊断分析

Coronary artery calcification computerized tomography(CT) diagnosis and analysis of 63 cases

目的 :观察冠状动脉钙化 (CAC)的 CT表现及临床意义。方法 :对 2 0 8例胸部 CT图像及临床资料作分析。结果 :2 0 8例胸部CT图像中发现 CAC 63例 (30 .3% )。 40岁以上者 ,CAC检出率随年龄的增加而增加 ,不同年龄组 CAC率差异有显著性 (P<0 .0 1 )。 56例诊断冠心病者 ,41例有 CAC (73.2 % ) ;1 0 2例无冠心病者 ,2 2例有 CAC(2 1 .6% ) (P<0 .0 1 )。结论 :CT能及早发现 CAC,这对冠心病的诊治提供了有力的依据。

Objective:To observe the CT manifestations of coronary artery calcification(CAC) and their clinical significance Methods:The chest CT images and clinical data from 208 cases were analysed Results:Among the 208 cases,CAC were found in 63 patients (30 3%) The incidence of CAC increased with ages in patients over 40 years old ( P <0 01) The CAC rates were significant difference between different age groups In 56 cases with coronary arteriosclerotic heart disease (CAHD),41 had CAC (73 2%);but in 102 patients without heart disease,only 22 had CAC (21 6%)( P <0 01) Conclusion:CT scan could detect CAC earlier,and provide sound evidence for diagnosis and treatment of coronary arteriosclerotic heart disease
