急性心肌梗死患者白细胞与住院死亡率的关系

Relationship between white blood cell and hospital mortality in patients with acute myocardial infarction

目的:探讨急性心肌梗死患者白细胞(WBC)计数及中性粒细胞比率(N)与住院死亡率的关系。方法:选择262例急性心肌梗死(Acute myocardial infarction,AMI)住院患者,在入院24h内采集患者静脉血检测白细胞计数及中性粒细胞比率。结果:262例患者院内死亡47例(17.9%)。饮酒可能降低AMI患者的住院死亡率。随着白细胞计数及中性粒细胞比率增高,住院死亡率呈上升趋势,WBC≤10×109个/L组与WBC>15×109个/L组,N<0.8组与N≥0.9组比较有统计学差异。结论:AMI患者白细胞计数及中性粒细胞比率越高,住院死亡率越高,白细胞计数及中性粒细胞比率对判断AMI患者的病情危险性及预后有着重要价值。

Objective：To investigate relationship between white blood cell count , neutrophil ratio and hospital mortality in patients with acute myocardial infarction （AMI）. Methods：262 subjects with AMI were selected and venous blood was collected in 24 hours after hospital admission. Results： 47 subjects died and hospital mortality was 17.9%. Drink depressed hospital mortality in patients with AMI. As white blood cell count and neutrophil ratio increased, hospital mortality had a rising trend. Hospital mortality in group of WBC ≤10× 10^9 and group of WBC 〉 15×10^9 had statistical difference. The same difference was found with group of N 〈0.8 and group of N 90.9. Conclusion：The more white blood cell count and neutrophil ratio, the more hospital mortality. Blood cell count and neutrophil ratio play important role in caisis and prognosis of patients with AMI.
