摘　　要：目的 :运用利声显静脉心肌声学造影的方法评价心肌梗塞患者经血管再通术后心肌微循环 ,探讨无再流 ( NR)与左心室重构的关系。方法 :对 2 7例心肌梗塞患者根据术后一周心肌声学造影 ( MCE)结果分成 NR组与非 NR组 ,并与其后一月内二维超声随访的结果进行比较。结果 :非 NR及 NR组左室收缩及舒张末期内径术后第1周与术后第 5周的变化在二组间均有显著性差异 ( P<0 .0 5 )。 NR组患者中有 7例 ( 88% )左室舒张末期内径增大 ,而非 NR组中只有 2例 ( 11% ) ( P=0 .0 0 1)。结论 :术后 NR的患者发生左室重构的可能性较非 NR者大。Objective:To evaluate the microcirculation in the patients after revascularization by myocardial contrast echocardiography(MCE)using intravenous injection of Levovist and to assess the relationship between the no reflow(NR)and left ventricular remodeling.Methods:Twenty seven patients with previous myocardial infarction who had undergone revascularization and fulfilled follow up were studied.Results:There was significant difference in change of end systolic and end diastolic diameter of left ventricle during lst and 5th week follow up between NR and non NR groups(all P <0 05).The enlargement of left ventricular end diastolic diameter was occurred in 7 patients(88%) in NR group and 2 patients (11%)in non NR group( P =0 001)during follow up.Conclusions:Patietns with NR are more probably to have ventricular remodeling in the follow up after revascularization.
