用心电图记分法，分三组对１５５例应用静脉溶栓治疗或常规治疗的急性心肌梗塞（ＡＭＩ）患者的最初和最后梗塞面积、最初和最后左心室射血分数（ＥＦ）进行了统计分析。结果显示：溶栓治疗再通组的最后梗塞面积与对照组相比明显缩小（Ｐ＜０．０５），与溶栓未通组相比亦缩小显著（Ｐ＜０．００１）．溶栓再通组的梗塞心肌存活率明显高于对照组（Ｐ＜０．００１）及溶栓未通用（Ｐ＜０．０５）其心肌挽救达５５％。溶栓再通组最后ＥＦ较未通组及对照组提高明显，其ＥＦ提高的百分比明显高于溶栓未通组及时间组，并具有统计学意义（Ｐ＜０．０５）。而溶栓未通组及对照组最后便塞面积略有缩小、ＥＦ稍有提高，但均无统计学意义（Ｐ＞０．０５）。
Electrocardiographic scoring was used to statistically analyze the initial and final infarct size, initial and final left ventricular ejection fraction (EF) in 155 patients with acute myocardial infarction (AMI) treated with intravenous thrombolysis or conventional therapy in three groups. The results showed that the final infarct size of Thrombolytic Therapy recanalization group was significantly reduced compared with the control group (P <0.05), and significantly reduced compared with the thrombolytic group (P <0.001). The survival rate of infarcted myocardium in thrombolytic group was significantly higher than that in control group (P <0.001) and thrombolytic therapy was not common (P <0.05). The final EF of the thrombolysis recanalization group was significantly higher than that of the control group and the non-recanalization group. The percentage of EF improvement was significantly higher than that of the failed group and the time of thrombolysis group (P <0.05). However, the area of the last plug of thrombolysis group and control group was slightly reduced, EF slightly increased, but no statistical significance (P> 0.05).
