Abstract：Objective:To investigate the value of coronary calcium score assessed by dual-source computed tomography coronary angiography in the diagnosis of coronary artery stenosis.Method:The DSCT scanned data of 84 suspected coronary heart disease patients in our hospital from June 2012 to December 2013 were retrospectively analyzed,including CACS of coronary artery CT angiography by dual-source CT and CAG,Gensini score was used to evaluate the degree stenosis of coronary artery.The correlation between the two methods was evaluated using Spearman correlation analysis.With CAG as the reference standard, the capability to predict obvious coronary stenosis was compared using ROC curve.Result:There was a positive association between calcium score and Gensini score(r=0.718,P<0.001).Calcium scoring had an acceptable value for diagnose CA stenosis≥50% with optimal cutoff point of 321,yielding a sensitivity, specificity and the area under the AUC were 85%,77% and 0.868,respectively.Conclusion:Calcium score for predicting coronary artery above moderate stenosis has a high value,for the clinical diagnosis of coronary heart disease and provide a reliable noninvasive method.
