冠状动脉造影阴性的女性胸痛患者核素心肌灌注显像结果分析

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),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).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.
