摘要
目的:应用心肌ECT灌注断层显像和门控左心室核素功能显像显示心绞痛组(AN)的心肌摄取99Tcm-MIBI和心室功能变化。方法:对男性心绞痛患者52例、阴性对照组31例(正常人)和陈旧性心肌梗塞组(OMI)59例分别进行心肌灌注显像和门控左心室核素功能显像,对左心室舒缩功能参数进行组间协方差分析,并比较组间心肌摄取异常病灶分布情况的差异。结果:AN组心肌摄取异常病灶多为单发(P<0.01),且总的异常节段数低于OMI组(P<0.01);AN组的心舒缩功能参数与对照组无显著性差异(P>0.05),但是显著高于OMI组(P<0.01)。结论:AN心肌摄取和心室功能改变的显示有助于心绞痛的准确诊断及其发病机制的探讨。
Objective: To assess the changes in myocardial uptake 99Tcm-MIBI and ventricular function in male angina(AN) with cordis ECT imaging. Methods: Fifty two angina and 31 age-matched healthy subjects and 59 obsolete miocardial infarction underwent 99Tcm-MIBI myocardial imaging and gated ventrichlar imaging. Statistical analysis of covariance and analysis of multipe regression were used to investigate ECT myocardial imaging and parameters of diastolic and retractile function in left ventricular ,and compare differences of myocardial uptake 99Tcm-MIBI. Results: The focus of AN myocardial uptake most was single(P<0.01;. The sum of myocardial focus is obvious less than OMI(P<0.01;. The diastolic and retractile function in left ventricular of SMI didn't show the difference of in the age-matched healthy subjects(P>0.05;,and was obvious more than OMI(P<0.01;. Conclusion: 99 Tcm -MIBI uptake of cardiac muscle and ventricular function connection was shown by ECT imaging is helpful to the diagnosis and for the study of the pathophysiology of AN.
