摘　　要：目的 :应用门电路核素心室显像及小剂量多巴酚丁胺 (DOB)负荷试验 ,对急性心肌梗死 (AMI)早期再灌注后左室舒张功能进行评价。方法 :指标采用高峰充盈率 (PFR)、平均充盈率 (MFR)、 1/ 3充盈率 (1/ 3FR) ,1/ 3充盈分数 (1/ 3FF)。结果 :DOB负荷前后 ,AMI组PFR、MFR、 1/ 3FR均显著低于对照组 (P <0 0 1及P <0 0 5 )。AMI组DOB负荷后上述指标均有一定程度的改善 (P <0 0 1)。结论 :AMI再灌注后左室舒张功能降低 ,而小剂量DOB负荷后可得到明显改善 。Objective:To assess the left ventricular diastolic function after reperfusion in AMI patients with thrombolytic therapy.Methods:Low-dose dobutamine stress radionuclide Ventriculography was performed in 23 cases of AMI patients and 13 cases of control group.The following parameters were selected:PFR,MFR,1/3FR,1/3FF.Results:With or without dobutamine stress,The PFR,MFR,1/3FR of AMI patients were all in lower lever than those of control significantly (p<0 01.and p<0 05).In AMI group,the parametets metioned above after DOB stress were improved comparing with those before dobutamine Stress (p<0 01).Conclusion:The diastolic function of left ventricle after reperfusion were all depressed,and the cardiac function improved with low-dose dobutamine stress.
