摘　　要：目的:探讨老年男性陈旧心肌梗死患者的心脏功能学变化特点,提高早期诊断的准确性和敏感性。方法:对45例心肌缺血(AN)、31例阴性对照组和69例陈旧心肌梗死(OMI)分别进行心肌灌注断层显像和门控心室功能ECT显像。比较3组断层显像间心肌各壁放射性分布的状况及左心室舒缩功能参数的变化。结果:AN组呈现可逆性放射性缺损或分布减低;除最大充盈时间(TPFR)外,各组的左室射血分数(EF)和峰值充盈速率(PFR)间差别具有统计学意义。结论:AN对心肌的损害和引起PFR和PER减低较OMI组轻,OMI对心脏舒缩功能有显著性影响。Objective： To observe the characteristic changes of cardiac function in elder males patients with obsolete myocardial ischemia and to raise diagnostic accuracy and sensibility. Methods： 45 angina and 31 age-matched healthy subjects and 69 obsolete myocardial infarction were examined by myocardial tomography imaging and gated ventrichlar imaging. The differents of radioactive distribution in myocardial and the parameters of diastolic and retractile function in left ventrichlar among the three groups were compared. Results： The angina group displayed radioactive reversible defect or reduce. Expect TPFR,EF and PFR had statistical difference （P〈0.05）in three groups. Conclusion： The myocardial damage induced by AN is less than that induced by OMI. The diastolic and retractile function of left ventrichlar can be remarkable influenced by OMI.
