摘　　要：目的:了解急性心肌梗死(AMI)对左心室舒张功能的影响及其与泵功能受损的关系。方法:利用心阻抗血流图观察36例AMI患者左心室主动舒张期功能,检测主动舒张期(A_2-O)、射血分数(EF)、心脏指数(CI)三项指标,并设心绞痛组和对照组。结果:AMI组左心室功能三项参数与对照组比较明显异常(P<0.001)。A_2-O延长的发生率(60%)高于EF减低的发生率(40%),P<0.01。A_2-O值与CI值呈高度负相关(r=-0.61),P<0.01。结论:AMI患者在左心室收缩功能障碍的同时,也存在明显舒张功能障碍,且与泵功能受损的关系更为密切。Objective：Revealed the relationship among acute myocardial infarction and left ventricular diastolic function and the impact of pump function.Method：Observed left ventricular diastolic function in 36 cases patients with myocardial infarction by heart impedance blood flow diagram,detected angina group and control group＇s three indicators：active diastolic phase,ejection fraction,cardiac index.Result：There was significant difference between angina group and the normal group（P〈0.001）,the incidence of active diastolic phase extended（60%）higher than the incidence of ejection fraction reduced （40%）,active diastolic phase and cardiac index showed a high negative correlation（r=-0.61 ,P〈0.01 ）.Conclusion：As ayocardial infarction patients with left ventrieular systolic obstacles,there was a clear diastolic dysfunction and a closer relationship of impaired pump function.
