摘　　要：目的探讨心肌显像（ＭＩＢＩ）与超声心动图（ＵＣＧ）对冠心病危险性的分级预测价值。方法对１７４例怀疑和已知冠心病患者进行ＭＩＢＩ和ＵＣＧ检查，分为正常、缺血、梗塞和缺血＋梗塞，将患者分为心脏事件发生组和无心脏事件组，分析ＭＩＢＩ和ＵＣＧ显像与心脏事件发生的关系。结果ＭＩＢＩ和ＵＣＧ检测相同率较高（６５．５％），ＭＩＢＩ和ＵＣＧ异常者易发生心脏事件，两者均异常者心脏事件发生率最高（３０％）。结论 ＭＩＢＩ和ＵＣＧ相关性良好，结合应用时ＵＣＧ异常可增加ＭＩＢＩ的危险性分级预测能力。Objective To evaluate the risk stratification value of 99mTc-MIBI myocardial per- fusion imaging (MIBI) combined with echocardiogram (UCG) for patients with suspected coronary heart disease(CHD) and known CHD. Methods 174 patients were classified as normal, ischemia, infarction and ischemia+infarction according to the MIBI and UCG imaging. All patients were divided into non-heart event group and heart event group. Relation between MIBI and UCG imaging and the incidence of heart events were analyzed. Results The coincidence rate of MIBI and UCG imaging reached 65. 5%. Patients who had a positive MIBI or UCG imaging had a high rate of heart events. Patients with both positive imagining of MIBI and UCG Were demonstrated a very high heart event incidence (30% ). Conclusion There is a good correlation between MIBI and UCG and the latter can increase the value of risk stratification of the MIBI.
