目的观察应激性高血糖浓度对急性心肌梗死预后的影响。方法选择符合急性心肌梗死诊断标准且有糖耐量异常患者183例,按入院后空腹血糖数值分为两组;糖耐量减低组65例,糖尿病组118例;观察两组患者血糖的变化、并发症发生的情况和死亡率。结果糖耐量减低组组患者出现并发症者18例,糖尿病组出现并发症者51例,χ2=4.30,P<0.05;糖耐量减低组30 d死亡6例,糖尿病组30 d死亡15例,χ2=0.50,P>0.05;糖耐量减低组1年内死亡12,糖尿病组1年内死亡38例,χ2=3.99,P<0.05。结论应激性高血糖浓度对缺血心肌的损害是肯定的,要及时监测和调控急性心肌梗死的血糖,阻断其对心肌细胞的进一步损害,以降低急性心肌梗死的病死率和并发症等。
Objective To observe the effect of stress hyperglycemia on the prognosis of acute myocardial infarction. Methods According to the diagnostic criteria of acute myocardial infarction, 183 patients with impaired glucose tolerance were divided into two groups according to the fasting blood glucose level after admission: 65 patients with impaired glucose tolerance and 118 patients with diabetes mellitus. The changes of blood glucose and complications What happens and mortality. Results There were 18 complications in patients with impaired glucose tolerance group, 51 complications in diabetic group (χ2 = 4.30, P <0.05), 6 in 30 d after glucose tolerance decrease and 15 in 30 d in diabetes mellitus (χ2 = 4.30, = 0.50, P> 0.05; in the group with impaired glucose tolerance, one died within one year; and in the diabetic group, 38 patients died within one year (χ2 = 3.99, P <0.05). Conclusions The stress hyperglycemia has a positive effect on ischemic myocardium. It is necessary to monitor and regulate the blood glucose in acute myocardial infarction in time and to prevent its further damage to myocardial cells, so as to reduce the mortality and complications of acute myocardial infarction .
