Abstract： 目的 观察双源CT冠状动脉血管成像(双源CTA)诊断较高心率者(≥75次/min)冠状动脉狭窄的效果.方法 51例冠心病患者,心率均≥75次/min,均接受双源CTA和传统冠状动脉血管造影(CAG)检查.结果 双源CTA、CAG均检出冠状动脉狭窄者94段,均未检出者359段,仅CAG检出者34段,仅双源CTA检出者20段.以CAG结果为金标准,双源CTA诊断高心率冠心病患者冠状动脉狭窄的敏感度为73.44%,特异度为94.72%,符合率为89.34%,阳性预测值为82.46%,阴性预测值91.35%.结论 双源CTA诊断偏高心率冠心病患者(心率≥75次/min)冠状动脉狭窄(≥50%)效果较好.
