对５２例急性心肌梗塞（ＡＭＩ）患者观察了１个月内心电图的变化及ＱＲＳ记分情况。病例分为溶栓再通组、未通组及对照组。对三组的ＳＴ段回落及ＱＲＳ记分情况进行了对比分析。结果表明：溶栓再通组ＳＴ段回落迅速而显著（Ｐ＜０．０５），甚至１个月时与对照组比较仍有显著性差异。ＱＲＳ记分表明：１个月后再通组ＱＲＳ记分明显降低，与对照组比较，有显著性差异（Ｐ＜０．０５）。未通组ＱＲＳ记分略降低，但无统计学意义。提示ＡＭＩ早期进行静脉溶栓治疗，达到早期再灌注可挽救更多的濒死心肌细胞，并缩小梗塞面积，改善心泵功能。
Fifty-two patients with acute myocardial infarction (AMI) were observed within 1 month ECG changes and QRS score. The cases were divided into thrombolytic group, failed group and control group. The three groups of ST segment regression and QRS score were compared. The results showed that the thrombolysis recanalization ST-segment drop quickly and significantly (P <0.05), even 1 month compared with the control group there are still significant differences. The QRS score showed that QRS score of re-treatment group decreased significantly after one month, which was significantly different from that of control group (P <0.05). The QRS score of the failed group was slightly lower but not statistically significant. Prompt AMI intravenous thrombolytic therapy early, early reperfusion can save more dying cardiomyocytes, and reduce infarct size, improve cardiac pump function.
