摘　　要：目的 :采用多巴酚丁胺负荷超声心动图 ( DSE)试验评价急性心肌梗死 ( AMI)恢复期患者左室容积 ( L VV)的变化及其意义。方法 :DSE采用分级负荷方法 ,用动态三维超声心动图 ( 3- DE)测定 32例正常人 ( A组 )和 35例 AMI恢复期患者 ( B组 ) L VV。结果 :两组静息状态 L VV无显著性差异 ;DSE过程中 A组逐步缩小 ,而 B组在低负荷时缩小 ,高负荷时较静息状态扩大 ,与 A组相比有极显著性差异 ( P <0 .0 1)。结论 :以 3- DE行 DSE能通过 LVV的改变了解 AMI恢复期的心功能状态。Objective:To evaluate the alteration and its significance of left vcntricular volume ( L VV) in the convalescent patients with acute myocardial infarction( AMI) by dobutamine stress echocardiography ( DSE) test.Method:Multistage DSE and dynamic 3- dimensional echocardio- graphy( 3- DE) were performed to calculate LVV in32 controls( Group A) and35 convalescent pa- tients with AMI( Group B) .Results:No difference was found between the two groups in LVV at baseline.During DSE,L VV decreased gradually in Group A,but in Group B,there was a small de- cease at low stress and an enlargement at large stress in comparison with baseline.At peak stress, LVV was significantly different between the two groups( P <0 .0 1) .Conclusion:With3- DE pro- viding with accurate L VV,DSE is a good method to understand the function of the convalescent pa- tients with AMI.
