本文对40例冠心病患者和32例正常人在潘生丁药物负荷前、后进行99mTc－MIBI心肌断层显像的资料进行了分析。结合潘生丁药物负荷前、后的99mTc－MIBI心肌断层图像和靶心图可对冠心病心肌缺血或心肌梗塞的部位、范围及严重程度作出有意义的评价，并可观察左室腔的大小和室壁厚薄等情况。其诊断冠心病的灵敏性为92．5％、特异性为87．5％。本文发现早期冠心病负荷显像表现的缺血区在静息状态下显像大多可恢复供血，其左室腔大小均正常，且无室壁增厚，此时普通心电图及心脏超声一般难以发现异常；而严重缺血或心肌梗塞在静息状态下显像，仅部份恢复或不恢复，部份病例并表现出左室心腔扩大及正常部位心肌代偿性增厚。
In this paper, 40 cases of coronary heart disease patients and 32 normal subjects in the dipyridamole drug load before and after 99mTc-MIBI myocardial tomography data were analyzed. Combined with 99mTc-MIBI myocardial infarction images and the bull’s-eye image before and after dipyridamole drug loading, we can make a meaningful assessment of the location, extent and severity of myocardial ischemia or myocardial infarction in coronary heart disease. The size of left ventricular cavity and the wall Thickness and so on. The diagnosis of coronary heart disease was 92.5% sensitivity and specificity of 87.5%. This paper found that early ischemic coronary angiography of the ischemic area at rest, most of the imaging can be restored to the blood supply, the size of the left ventricular cavity were normal, and no wall thickening, when general ECG and cardiac ultrasound is generally difficult to find Abnormalities; and severe ischemia or myocardial infarction in resting state imaging, only partial or no recovery, in some cases and showed the expansion of the left ventricle and normal heart myocardial compensatory thickening.
