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203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 explore the differences of the sensitivity of 64-slice spiral CT in the diagnosis of coronary artery stenosis in the elderly and middle-aged patients. Methods The clinical data of 203 patients with coronary artery stenosis confirmed by coronary angiography were analyzed. Results The sensitivity of mild, moderate and severe coronary artery stenosis was 78.3%, 79.2% and 90.6% respectively in elderly patients. The sensitivity of middle-aged and young patients were 91.8%, 86.7% and 91.7% respectively. Conclusions The sensitivity of 64-slice spiral CT in the diagnosis of coronary artery stenosis in elderly patients is lower than that in middle-aged and young patients. There is no significant difference in the sensitivity of severe stenosis.
