目的：评价一次显像同时获得心肌灌注和心肌壁收缩功能、室腔射血功能的改变在冠心病中的临床意义。方法：①用自动门控定量分析软件，获得舒张末期容积（ＥＤＶ）、收缩末期容积（ＥＳＶ）和ＬＶＥＦ对正常、心梗、心肌缺血三组做了统计和分析。②将舒张末期（ＥＤ）灌注、局部ＥＦ、局部壁运动、和壁增厚度４个靶心图各划分为９个区段计算心梗组各项异常节段并作分析。结果：①心梗组和正常组心室功能参数差别有显著性，心肌缺血组与正常组差别无显著性。②心梗组灌注异常节段大多伴有心肌壁功能受损（６７／８３），但存在更多心肌壁功能受损节段在灌注正常区（１８个）；灌注异常阶段中尚有１０个节段壁功能正常。结论：门控心肌断层显像整体心室功能参数在心梗的评价中有优越性对心肌缺血的诊断价值不大；心梗中存在有不少的局部灌注与心肌壁功能异常节段的不匹配，对心肌存活的评价有帮助
OBJECTIVE: To evaluate the clinical significance of myocardial perfusion and myocardial wall contraction in one imaging and the change of ventricular ejection function in coronary heart disease. Methods: ①Automatic gated quantitative analysis software was used to obtain the end-diastolic volume (EDV), end-systolic volume (ESV) and LVEF in three groups of normal, myocardial infarction and myocardial ischemia were statistically analyzed. ② The endocardial end-diastolic (ED) perfusion, local EF, local wall motion, and wall thickening of the four bull’s-eye maps were divided into 9 sections to calculate the myocardial infarction segment abnormalities and analyzed. Results: ① There were significant differences in ventricular function parameters between myocardial infarction group and normal group, but there was no significant difference between myocardial ischemic group and normal group. (2) Most of the myocardial perfusion abnormalities in myocardial infarction group were associated with impaired myocardial wall function (67/83), but there were more myocardial dysfunction segments in normal perfusion zone (18), and 10 Segmental wall function is normal. Conclusions: Gated myocardial perfusion imaging has superiority in the evaluation of myocardial infarction in the evaluation of global ventricular function parameters; the myocardial infarction has many local perfusion and myocardial dysfunction segments Matching, the evaluation of myocardial survival helpful
