摘　　要：目的:探讨心肌梗死后心肌存活面积与心功能的关系。方法:对98例曾患有心肌梗死的患者,用硝酸甘油介入、99Tc-甲氨基异丁基异氰(99TcmMIBI)二次扫描方法测定存活心肌面积,同时计算出心功能指标。结果:存活心肌面积大组与存活心肌面积小组平均年龄及有无心力衰竭、心脏扩大等各项危险因素例数比较,差异无显著性意义(P>0.05);前者的严重心律失常的发生率为58.2%,后者为25.6%,2组有显著差异(P<0.01)。结论:提示心肌梗死后存活心肌面积与心功能和心率失常密切相关。AIM:To investigate the relationship between myocardial viability and presence of arrhythmia in patients with the history of myocardial infarction. METHODS:Ninety eight patients with the history of infarction were studied.Myocardial viabilities were detected by 99TcmMIBI myocardial tomography with nitroglycerin administration. The presence of arrhythmia was detected by 24 hour ambulatory electrocardiography. RESULTS:Fifty five(56.1%) out of the 98 patients had improvement of perfusion after nitroglycerin administration.Among them,arrhythmia was found in 32 patients(58.2%),compared with 11 patients(25.6%) with arrhythmia in the group without myocardial viability(P< 0.01).CONCLUSION:Myocardial viability in patients with the history of myocardial infarction is closely related to cardiac function and a higher frequency of arrhythmia.
