摘　　要：目的　探讨核素心肌断层显像对心尖肥厚型心肌病 (AHCM)的诊断价值。方法　 32例有特殊心电图改变、疑为AHCM的患者行超声心动图 (UCG)、99Tcm 甲氧基异丁基异腈 (MIBI)心肌断层显像、冠状动脉造影及左室造影等检查。结果　 32例患者中确诊为AHCM者 2 9例 ,UCG与核素心肌断层显像诊断灵敏度分别为 93.1%和 89.7% ,两者差异无显著性 (P >0 .0 5 )。结论　99Tcm MIBI心肌断层显像是诊断AHCM一种有效无创的方法。ObjectiveTo evaluate the value of radionuclide 99Tcm-MIBI myocardial scanning for the diagnosis of apical hypertrophic cardiomyopathy(AHCM). MethodsThirty-two cases with typical ECG of AHCM were studied by ultrasonic cardiography (UCG), radionuclide 99Tcm-MIBI myocardial scanning, coronary angiography and left ventriculography. THResultsTwenty-nine patients were diagnosed with AHCM. The diagnostic sensitivity of SPECT vs UCG in AHCM was 89.7% vs 93.1%. The specificity was 100% for both. There was no significant difference in diagnosis of AHCM between UCG and ECT. ConclusionSPECT is an effective method for diagnosing AHCM.
