用ST段预测法和QRS积分法计算32例冠状动脉内尿激酶溶栓和17例常规治疗急性心肌梗塞的最初和最后梗塞面积。结果显示,溶栓治疗组最后梗塞面积显著缩小(15.2±5.6%VS 22.4±6.2％,P<0.01),其中溶栓再通组最后梗塞面积显著小于最初梗塞面积(P<0.01),溶栓未通组虽最后梗塞面积缩小,但无显著性差异(P>0.05)。常规治疗组最后梗塞面积无显著变化(P>0.05)。溶栓再通组、未通组和常规治疗组的心肌挽救率分别为91.7％、25.0%和5.9%。
The initial and final infarct size of 32 patients with intra-urokinase thrombolysis and 17 patients with conventional acute myocardial infarction were calculated by ST segment prediction and QRS integration. The results showed that the final infarct size was significantly reduced in the thrombolysis group (15.2 ± 5.6% VS 22.4 ± 6.2%, P <0.01), and the final infarct size in the thrombolysis recanalization group was significantly less than the initial infarct size (P <0.01) Although the final infarction area was reduced, there was no significant difference (P> 0.05). Conventional treatment group, the final infarct size no significant change (P> 0.05). The myocardial salvage rates of thrombolytic group, untreated group and routine treatment group were 91.7%, 25.0% and 5.9% respectively.
