血糖浓度增高对急性心肌梗死愈后的影响

Influence of hyperglycemia on the prognosis of acute myocardial infarction

目的:回顾性地了解无论是否伴有糖尿病,血糖浓度增高对急性心肌梗死住院病死率及心梗后心衰、心源性休克的影响。方法:心肌梗死住院病人100例,将入院时血糖浓度<6.6mmol/L作为A组,血糖浓度在6.6～11.1mmol/L者作为B组,血糖浓度>11.1mmol/L作为C组,分别计算各组发生心衰、心源性休克的百分率及住院病死率。结果:A组心衰发生率为10.71％,心源性休克发生率为3.57％,住院病死率为3.57％;B组心衰发生率为41.18％,心源性休克发生率为29.41％,住院病死率为26.47％;C组心衰发生率为52.63％,心源性休克发生率为31.58％,住院病死率为26.32％。B组、C组心衰发生率、心源性休克发生率及住院病死率比A组明显增加,差异有显著性。而B组与C组心衰发生率、心源性休克发生率及住院病死率无显著性差异。结论:血糖浓度增高,心衰、心源性休克发生率及住院病死率也明显增高。

Objective;To investigate retrospectively the influence of hyperglycemia in patients with or without diabetes mellitus on the rates of in-hospital mortality, congestive heart failure and cardiogenic shock after acute myocardial infarction. Method: One hundred in-patients with myocardial infarction were divided according to their level of blood glucose into Group A, whose blood glucose level < 6. 6mmol/L; Group B, whose blood glucose level > 6. 6mmlo/L and < 11. 1mmlo/L and Group C, whose blood glucose level>11. 1mmol/L. The percentage of patients with congestive heart failure, cardiogenic shock and in-hospital mortality of each group were calculated. Results:The values of Group B and Group C were significantly higher than those in Group A, while the differences in values between Group B and Group C were not significant. Conclusion:The risks of congestive heart failure,cardiogenic shock and in-hospital death after myocardial infarction are significantly increased in patients with hyperglycemia.
