７６例急性心肌梗塞病人进行尿激酶静脉溶栓治疗。溶栓后４周和６个月时，前侧壁梗塞再通病人的左室舒张末容量、收缩末容量均低于未通者，左室射血分数高于未通者，严重节段室壁运动异常节段的百分率较未通者显著减少（Ｐ＜０．０１）；下后壁梗塞再通者与未通者无显著性差异。提示早期溶栓再灌注可使前侧壁梗塞病人的左心功能得到显著改善。 76 patients with acute myocardial infarction were treated with intravenous thrombolysis of urokinase. At 4 weeks and 6 months after thrombolysis, left ventricular end-diastolic volume, end-systolic volume in patients with recanalization of the anterior lateral wall were significantly lower than those in the control group, and left ventricular ejection fraction was higher than those in the unresectable group. Severe segmental compartment The percentage of abnormal wall motion segment was significantly lower than that of the non-communicating artery (P <0.01). There was no significant difference between the inferior posterior wall infarction recanalization and the non-communicating. Tip early thrombolytic reperfusion in patients with anterior infarction can be significantly improved left ventricular function.
