目的 观察急性心肌梗死 (AMI)患者急性期白细胞 (WBC)数与病死率的关系 ,探讨白细胞增高对临床预后的意义。方法 收集 12 0 8例AMI的临床资料 ,按WBC高低分 6组 ,同时比较各组间心率、血压、心肌酶、血糖、血脂及临床表现资料 ,进行统计学分析。结果 WBC与病死率呈显著正相关 (r =1 0 0 ,P =0 0 0 5 )与肌酸激酶 -同功酶 (CK -MB)也呈正相关 (r =0 82 ,P =0 0 4 6 ) ,同时不同WBC数组间心率、胆固醇 (TC)、血糖、吸烟也有显著性差异 (P <0 0 5 )。结论 升高的WBC是AMI不良预后的标志。
Objective To observe the relationship between the number of leucocytes (WBC) and mortality in patients with acute myocardial infarction (AMI) and to investigate the significance of the leukocytosis in clinical prognosis. Methods The clinical data of 1208 AMI patients were collected and divided into 6 groups according to their WBC levels. Heart rate, blood pressure, myocardial enzymes, blood glucose, blood lipids and clinical manifestations were also compared between groups for statistical analysis. Results There was a significant positive correlation between WBC and mortality (r = 100, P = 0 055) and creatine kinase-isoenzyme (CK-MB) 6). Heart rate, cholesterol (TC), blood sugar and smoking were also significantly different among different WBC arrays (P <0.05). Conclusion The elevated WBC is a sign of poor prognosis of AMI.
