摘　　要：目的:评价无症状心肌缺血穴SMI雪和心绞痛(AN)对左心室舒缩功能的影响。方法:入选者包括对照组30例,陈旧性心肌梗死患者66例穴OMI组雪熏SMI组39例,AN组75例。均行门控心室功能显像和心肌灌注断层显像检查,将年龄作为协变量对各组的舒缩功能参数进行协方差分析和两两比较。结果:除最大充盈时间(TPFR)外,4组左室射血分数(LVEF)、峰值充盈速率(PFR)和峰值收缩速率(PER)之间差别有统计学意义。SMI组和AN组此3指标均高于OMI组,且SMI组的PFR和PER高于AN组。结论:SMI对左心室的舒缩功能损害性影响程度较AN轻。Objective： To study the effects of silent myocardial ischemia （SMI） and angina （AN） on the diastolic and retractile function in left ventricle. Methods： All people were randomly divided into 4 groups including 30 in control group, 66 in old myocardial infarction group （OMI）, 39 in SMI group, and 75 in AN group. Gating ventricular imaging and radioactive imagine ECT examinations were performed. Results： There were significant differences of LVEF, PFR and PER among 4 groups except TPFR. The 3 indexes in SMI group and AN group were higher than those in OMI group, and PFR and PER in SMI group were higher than those in AN group. Conclusion： The damage of SMI is lighter than that of AN in the diastolic retractile function in left ventricle.
