摘　　要：目的探讨64层螺旋CT在诊断老年及中青年冠状动脉狭窄的敏感性等指标的差异。方法对163例经冠状动脉造影证实为冠脉狭窄患者的临床病例资料进行分析。结果老年患者轻、中、重度冠脉狭窄的敏感性分别为78.3%、79.2%、90.6%;中青年患者之敏感性分别为91.8%、86.7%、91.7%。结论64层螺旋CT诊断老年冠脉狭窄的敏感性低于中青年,轻、中度狭窄时差异有统计学意义,重度狭窄时敏感性无统计学差异。Objective To discuss the index difference of sensitivity of 64 - slice spiral CT in diagnosing coronary artery stenosis in the eld- erly and the young. Methods An analysis was made to the clinical data of 163 cases with coronary artery stenosis conformed by coronary angiography. Result The sensitivities of the elderly with mild, moderate and severe coronary artery stenosis were 78.3%, 79.2% and 90. 6% respectively while those of the young were 91.8%, 86.7% and 91.7% respectively. Conclusions The sensitivity of 64 - shce spiral CT in diagnosing coronary artery stenosis of the elderly is lower than that of the young, the difference is of statistical significance in diagnosing the mild and moderate stenosis but of no statistical significance in diagnosing the severe stenosis.
