为观察急性心肌梗死（ＡＭＩ）患者，静脉溶栓疗效与心脏收缩功能之关系。选８８例接受静脉溶栓治疗的ＡＭＩ患者，分为两组：溶栓再通组６６例及未溶通组２２例。以Ｋｉｌｉｐ分级判定临床心功能，超声心动图测定左室射血分数（ＬＶＥＦ）。结果显示：①重度左心功能不全（即ＫｉｌｉｐⅢ级）患者，溶通组明显少于未溶通组（１０．６％比３１．８％）；②室壁瘤出现率，溶通组明显少于未溶通组（９．１％比３６．４％）；③ＬＶＥＦ值，溶通组明显高于未溶通组（５８．３±１０．５比５０．９±１１．９）。以上比较的Ｐ值均＜０．０１。可认为经静脉溶栓使梗死相关血管再灌注后的ＡＭＩ患者，左心室收缩功能一定程度上得以保护。
To observe the relationship between the efficacy of intravenous thrombolysis and cardiac contractility in patients with acute myocardial infarction (AMI). A total of 88 AMI patients undergoing intravenous thrombolysis were divided into two groups: 66 patients in the thrombolytic group and 22 patients in the non-dissolving group. Clinical cardiac function was evaluated by Kilip grading and left ventricular ejection fraction (LVEF) by echocardiography. The results showed that: ① in patients with severe left ventricular dysfunction (ie, Kilip Ⅲ grade), the number of patients with lymphatic metastasis was significantly lower than that of patients without lymphatic (10.6% vs 31.8%); ② The incidence of aneurysm was significantly lower (9.1% vs. 36.4%). The LVEF values in the lytic group were significantly higher than those in the non-lymphatic group (58.3 ± 10.5 vs. 50.9 ± 11.9). The above P values were all <0.01. Can be considered by intravenous thrombolysis infarction related vascular reperfusion AMI patients, left ventricular systolic function to some extent be protected.
