目的研究急性前壁心肌梗死(心梗)与下壁心梗心律失常对预后的影响。方法 98例心梗患者,将患者按病发部位分为前壁心梗组(48例)和下壁心梗组(50例)。所有患者在100 ml生理盐水中加入100万~150万U尿激酶,并在30 min内采用静脉滴注的方式输入到患者体内。采用pm8000型参监护仪对患者的心律状况进行连续3 d的监测。对比两组患者预后。结果前壁心梗组发现陈旧性心肌梗死14例,占29.17%;下壁心梗组发现陈旧性心肌梗死6例,占12.00%。前壁心梗组出现陈旧性心肌梗死患者的比例明显高于下壁心梗组(P<0.05)。前壁心梗组出现28例心律失常现象,其中3例患者因心律失常死亡,心律失常发生率为58.33%,死亡率为6.25%。下壁心梗组出现32例心律失常现象,6例患者因心律失常死亡,心律失常发生率为64.00%,死亡率为12.00%。下壁心梗组心律失常发生率及病死率均高于前壁心梗组(P<0.05)。结论急性前壁心梗与下壁心梗心律失常对预后有显著影响。
Objective To study the effect of arrhythmia of acute anterior myocardial infarction (MI) and inferior myocardial infarction on prognosis. Methods A total of 98 patients with myocardial infarction were divided into the anterior myocardial infarction group (48 cases) and the inferior myocardial infarction group (50 cases) according to the disease site. All patients in 100 ml of saline added 1 million to 1.5 million urokinase, and within 30 min by intravenous infusion into the patient’s body. The patient’s heart rate was monitored continuously for 3 days using pm8000 Patient Monitor. The prognosis of two groups was compared. Results In the anterior wall myocardial infarction group, 14 cases of old myocardial infarction were found, accounting for 29.17%. Six cases of old myocardial infarction were found in inferior wall myocardial infarction group, accounting for 12.00%. The proportion of patients with anterior myocardial infarction in the anterior myocardial infarction group was significantly higher than that in the inferior myocardial infarction group (P <0.05). There were 28 cases of arrhythmia in anterior MI group, of which 3 cases died of arrhythmia. The incidence of arrhythmia was 58.33% and the mortality rate was 6.25%. There were 32 cases of arrhythmia in the inferior myocardial infarction group, 6 cases died of cardiac arrhythmia, the incidence of arrhythmia was 64.00% and the mortality rate was 12.00%. The incidence and mortality of arrhythmia in the inferior myocardial infarction group were higher than those in the anterior myocardial infarction group (P <0.05). Conclusion Arrhythmia of acute anterior and inferior myocardial infarction have a significant effect on prognosis.
