【摘要】目的 探讨分析256层螺旋CT冠状动脉钙化积分在冠心病诊断的预测价值。方法 选取我院2013年2月～2014年2月进行冠状动脉钙化积分检查的189例患者，将其分为冠心病组和非冠心病组，分析比较两组钙化积分情况。结果 冠心病组显著高于非冠心病组(P<0.05)，差异有统计学意义。冠心病组四大分支血管的钙化积分分别和非冠心病组比较差异均有统计学意义(P<0.05)。结论 冠状动脉钙化积分可作为冠心病评价的有效指标，通过使用256层螺旋差异CT检查冠脉钙化及定量分析，对冠心病的预测及病变程度诊断有重要临床意义。

    【Abstract】Objective To discuss the value of calcification score of 256-slice spiral CT for the diagnosis of coronary artery disease. Methods Coronary artery imaging and calcification was performed with 256 sliced CT in 189 patients divided into CAD group and non-CAD group，the results were analyzed retrospectively. Results The average calcification score of CAD group was significantly higher than that of Non-CAD group (P<0.05). Conclusion Calcification score is of critical importance and 256-slice spiral CT was a valuable method to detect coronary arterial diseases.
