目的 探讨电子束CT(EBCT)检测冠状动脉钙化 (CAC)与冠脉造影 (CAG)所示冠状动脉狭窄间的关系。方法 对 48例临床有冠心病症状、可疑冠心病症状或无症状者行EBCT扫描及CAG。结果 (1)冠状动脉狭窄组的CAC率、CAC积分明显高于非狭窄组 ,P <0 0 0 1,P <0 0 1。(2 )随狭窄血管支数增加 ,CAC率、CAC积分显著升高 ,前者P <0 0 2 ,后者P <0 0 1。 (3)综合考虑敏感性及特异性 ,40～岁、5 0～岁、6 0～岁年龄组冠状动脉疾病 (CAD)预测值分别为 2 5分、10 0分、2 0 0分。结论 EBCTCAC是预测冠心病的有价值的指标。
Objective To investigate the relationship between Coronary artery calcification (CAC) and coronary artery stenosis (CAG) by electron beam computed tomography (EBCT). Methods EBCT and CAG were performed in 48 patients with clinical symptoms of coronary heart disease, suspicious coronary heart disease or asymptomatic. Results (1) The CAC rate and CAC score of coronary stenosis group were significantly higher than those of non-stenosis group (P <0.01 01, P <0.01). (2) With the increase of stenosis blood vessel count, CAC rate and CAC score increased significantly, the former P <0 0 2 and the latter P 0 01. (3) Considering the sensitivity and specificity, the predictive value of coronary artery disease (CAD) in 40 ~ 50 years old and 60 ~ 60 years old group was 25, 100, 200 respectively. Conclusion EBCTCAC is a valuable indicator of coronary heart disease.
