摘要
目的了解电子束ＣＴ（ＥＢＣＴ）检测冠状动脉钙化（ＣＡＣ）在国人中的状况；探讨其在临床冠心病诊断和预测中的价值和限度。材料与方法对经ＩｍａｔｒｏｎＣ－１５０型ＥＢＣＴ机检测ＣＡＣ的７１８例受检者进行研究。分析ＣＡＣ率和积分与年龄、性别及临床冠心病发病的关系，评价其对临床冠心病的诊断和预测价值。结果本研究中男性组的ＣＡＣ率为６５．３％，显著高于女性组（４５．５％，Ｐ＜０．００１）；男、女组ＣＡＣ率和积分均随年龄增加而显著增高（Ｐ＜０．００１）；冠心病组ＣＡＣ率与国外报道相仿，而ＣＡＣ积分却明显低于西方人；非冠心病组的ＣＡＣ率、积分均明显低于文献报道（３０～３９岁年龄段除外）；各年龄段冠心病组的ＣＡＣ率和积分均显著高于非冠心病组（Ｐ＜０．０５）。结论ＥＢＣＴ测定的国人ＣＡＣ与文献报道的西方人有一定差别；无ＣＡＣ或其积分较高对冠心病发病危险性预测的价值较大，有ＣＡＣ，但其积分较低时，对冠心病的诊断和预测应结合临床确定。
Purpose To understand the situation of coronary artery calcification (CAC) by electron beam computed tomography (EBCT) in Chinese and to explore its value and limit in the diagnosis and prognosis of clinical coronary heart disease (CHD). Materials and methods The study on CAC of 718 cases by Imatron C 150 EBCT scanner was made. The correlation of CAC incidence and score with age, sex and clinical CHD were analysed. Its diagnostic and predictive values for clinical CHD were eva luated. Results The incidence of CAC in men (65.3%) is significantly ( P <0.001) higher than that in women (45.5%). The CAC incidence and mean score in men and women increased significantly ( P <0.001) with age. The CAC incidence of the group with CHD was similar to that reported in foreign literature, but its score was appreciably lower than that of American. The CAC incidence and score of the group without CHD were appreciably lower than that reported in foreign literature. A significantly ( P <0.05) higher CAC incidence and score were seen in the CHD group as compared with the group without CHD. Conclusion In the Chinese, CAC by EBCT is different from Westerners. Absence of CAC or high CAC score is of greater value in predicting risk of clinical CHD. When CAC score is low, the clinical situations must be taken into consideration in the diagnosis and prediction of prognosis of clinical CHD.
