本文对100例冠心病病人和10例正常人进行运动和静息~(99m)锝—异睛(~(99m)TC—MIBI)心肌断层显象,即靶心显示。结果表明其诊断冠心病灵敏度为91％,特异性90％。病变室壁节段检出数比ECG更准确和灵敏,尤其对后壁、后侧壁及心尖部的梗塞定位诊断优于心电图。其与冠状动脉造影结果符合率高。显象检出的病变室壁节段数与CK—Mb值呈正相关(r=0.5946,P<0.001)。可作为无创伤性诊断冠心病的一种可靠检查方法。
In this study, 100 patients with coronary heart disease and 10 normal subjects underwent 99m Tc-99mTc-MIBI myocardial imaging, ie, bull’s-eye display. The results show that the diagnosis of coronary heart disease was 91% sensitivity and specificity of 90%. The detection of lesions in the wall segment is more accurate and sensitive than the ECG, especially for posterior wall, posterior wall and apical infarction diagnosis better than ECG. Its coincidence rate with coronary angiography is high. Visual examination revealed a positive correlation between the number of wall segments and CK-Mb (r = 0.5946, P <0.001). Can be used as a non-invasive diagnostic method of coronary heart disease a reliable.
