非糖尿病性持续性高血糖与一过性高血糖对急性心肌梗死患者预后的影响

【目的】探讨非糖尿病性持续性高血糖对急性心肌梗死（AMI）患者预后影响。【方法】将2010年8月至2012年8月本院收治的125例A M I住院患者排除糖尿病后，根据住院期间患者随机血糖值分为：A组（入院24 h后空腹血糖＜6．1 mmol/L ）；B 组（入院24 h 后空腹血糖＜6．1 mmol/L 且随机血糖＜9．0 mmol/L ）；C组（入院24 h后空腹血糖≥6．1 mmol/L或随机血糖≥9．0 mmol/L ）。分析比较各组恶性心律失常、心力衰竭、死亡的发生率。【结果】C组恶性心律失常、心力衰竭、死亡发生率均高于A组、B组，且差异有显著性（P ＜0．05）。B组恶性心律失常及心力衰竭的发生率均高于A组，且差异有显著性（P ＜0．05），A组与B组死亡的发生率相比较差异无显著性（ P＞0．05）。【结论】非糖尿病性持续性高血糖AMI患者的预后较一过性高血糖患者的预后差，检测其血糖水平对判断此类患者的预后具有一定的临床意义。

Effect of Non-diabetic Persistent and Transient Hyperglycemia on the Prognosis of Patients with Acute Myocardial Infarction

Objective] To explore the impact of non-diabetic persistent hyperglycemia on the prognosis of pa-tients with acute myocardial infarction （AMI） .Methods]Totally 125 AMI inpatients excluding diabetes mellitus in our hospital from Aug .2010 to Aug .2012 were recruited .According to hospitalization time ,all patients were divid-ed into group A（fasting blood sugar 24h after admission〈6 .1mmol/L） ,group B（fasting blood sugar 24h after ad-mission〈6 .1mmol/L and randomized blood sugar 〈9 .0mmol/L） and group C（fasting blood sugar 24h after admis-sion≥6 .1mmol/L or randomized blood sugar≥9 .0mmol/L） .The incidences of malignant arrhythmias ,heart failure and death in each group was analyzed and compared .Results]The incidences of malignant arrhythmias ,heart failure and death in group C were higher than those in group A and group B ,and there was significant difference （ P 〈0 .05） .The incidences of malignant arrhythmias and heart failure in group B were higher than those in group A ,and there was significant difference （ P 〈0 .05） .There was no significant difference in the incidence of death between group A and group B（ P〈0 .05） .Conclusion] The prognosis of AMI patients with non-diabetic persistent hyper-glycemia is poorer than that of patients with transient hyperglycemia .Blood sugar level is of clinical significance for forecasting the prognosis of these patients .
