目的探讨应激性高血糖对急性心肌梗死预后的影响。方法520例非糖尿病急性心肌梗死患者按早期血糖情况分A组(血糖正常或轻度升高,<72mmol/L)、B组(中度升高,72～111mmol/L)、C组(重度升高,>111mmol/L),进行24h动态心电监测,采用Wagner法计算心电图QRS积分。对各组梗死范围、主要并发症的发生率和病死率进行比较。结果应激性血糖升高提示心肌梗死范围的增大、心肌梗死并发症的增加、病死率的升高,预后凶险。结论应激性高血糖的变化是观察急性心肌梗死病情的发展和预后较敏感、简便、直观的指标。
Objective To investigate the effect of stress hyperglycemia on the prognosis of acute myocardial infarction. Methods 520 patients with non-diabetic acute myocardial infarction were divided into group A (normal or slightly elevated blood glucose <72mmol / L), group B (moderately elevated 72 ~ 111mmol / L), group C Elevated,> 111mmol / L), 24h Holter monitoring, using Wagner method to calculate ECG QRS integral. The infarct size, the incidence of major complications and the mortality were compared between groups. The results of stress-induced hyperglycemia prompted an increase in the scope of myocardial infarction, myocardial infarction complications increased mortality increased, the prognosis is dangerous. Conclusions The changes of stress hyperglycemia are more sensitive, simple and visual indicators for the development of acute myocardial infarction and the prognosis of acute myocardial infarction.
