摘　　要：目的了解核素心肌灌注显像(radionuclide myocardial perfusion imaging,MPT)对冠状动脉造影阴性的女性胸痛患者的临床评估价值。方法入选因胸痛就诊于我院并行冠状动脉造影检查阴性的女性患者55例,根据MPT检查结果,分为MPT阳性组及MPT阴性组,对两组患者的运动试验、血脂指标及高血压病、糖尿病、高血脂等合并症进行比较。结果 55例患者中MPT阳性组24例(43.6%),MPT阴性组31例(56.4%);MPT阳性组运动试验阳性率显著高于MPT阴性组(P<0.05);两组患者年龄、高血压、高血脂、糖尿病等合并症差异无统计学意义,血清各血脂指标差异亦无统计学意义(P>0.05),而外周动脉粥样硬化在MPT阳性组明显高于MPT阴性组(P<0.05)。结论女性胸痛患者仅以冠状动脉造影正常而诊断正常误诊率较高,对运动试验阳性、合并外周动脉粥样硬化的患者应行核素心肌灌注检查。Objective To evaluate the clinical value of radionuclide myocardial perfusion imaging（MPT）in female patients with normal coronary angiography.Methods A total of 55 female patients with chest pain and normal coronary angiography were separated according to myocardial perfusion imaging into two groups：MPT-positive group and MPF negative group.The electrocardiogram exercise test,blood lipid indexes and complications were compared between two groups.Results In all 55 patients,MPT-positive patients took up 43.6%（24cases）and MPT-negative patients accounted for 56.4%（31cases）.The positive rate of electrocardiogram exercise test was significantly higher in MPT-positive group than in MPT-negative group（P〈0.05）.The rate of peripheral atherosclerosis was significantly higher in MPT-positive group than in MPT-negative group（P〈0.05）.However,there were no significant difference in the indexes of blood lipid and their complications between two groups（P〉0.05）.Conclusion The misdiagnosis rate is higher in female patients with chest pain and normal coronary angiography,myocardial perfusion imaging is recommended in patients with positive electrocardiogram exercise test and peripheral atherosclerosis.
