摘要
目的探讨心脏ECT检测对冠心病的诊断价值。方法 216例胸闷、胸痛疑诊冠心病患者行静息状态下心脏ECT检测,收集相关临床资料及心脏ECT上心肌血流灌注、左心室各壁运动情况,并行QGS评分,对其中明确诊断为冠心病(指曾有急性心肌梗死史、曾行PCI术、或经冠脉CT或冠脉造影证实有冠心病)及明确排除冠心病(冠脉CT或冠脉造影证实冠脉无明显病变,无心梗及PCI史)的患者进行比较分析。结果 216例疑诊为冠心病的患者心脏ECT检测为正常血流灌注者42例,血流灌注减低者174例;174例患者中明确诊断为冠心病者86例,明确排除冠心病者48例,明确诊断为冠心病的患者ECT表现为心肌血流灌注减低合并室壁运动减弱的比率占95.3%(82/86),明确排除冠心病者ECT表现为心肌血流灌注减低合并室壁运动减弱的比率占6.25%(3/48)。结论静息心脏ECT表现为心肌血流灌注减低合并室壁运动减弱对冠心病诊断的准确率高。
[ Objective ] To evaluate the value of cardiac ECT detection in the diagnosis of coronary artery disease （CAD）. [ Methods ] 216 cases of chest tightness, or chest pain of suspected CAD underwent resting heart ECT detec- tion, the clinical data and left ventricular myocardial peffusion, wall motion, QGS score in the cardiac ECT, were collected. The patients were divided into myocardial blood peffusion decreased group and normal myocardial blood peffusion group. The myocardial blood peffusion decreased were further divided into two group： CAD group, had a- cute myocardial infarction history, has been undergoing PCI, or nan＇ow 〉50% in one of the three main coronary artery detected by CT coronary angiography or coronary angiography; and non- CAD group, there was no significant coronary narrow in one of the three main coronary artery detected by CT coronary angiography or coronaPy angiogra- phy. [Results] 216 patients of suspected CAD were detected by ECT. 42 patients were of normal blood flow, 174 patients were of myocardial blood peffusion decreased. In the 174 patients of myocardial blood peffusion decreased, 86 patients were CAD, 48 patients were excluded. The ratio of both myocardial peffusion and wall motion decreased in ECT were 95.3% （82/86） in CAD group, and 6.25% （3/48） in non-CAD group. [Conclusion] The accuracy of CAD is very high in both myocardial blood peffusion and wall motion decreased in ECT detection.
