摘　　要：目的探讨急性心肌梗死（AMI）患者人院时红细胞计数（RBC）和血红蛋白（Hb）水平与住院期间死亡的关系。方法以849例初发AMI住院患者为研究对象，收集入院时人口统计学、血RBC计数和Hb等生化指标，收集住院期间死亡资料，采用单因素和多因素分析方法，分析入院时血RBC计数和Hb水平与住院期间死亡的关联关系。结果死亡病例的入院RBC计数和HB水平显著高于存活病例。经单因素Logistic回归分析，RBC计数与住院期间死亡呈显著的关联关系（P〈0．01），但经多因素分析后，这种关联变得无统计学意义。经单因素分析，与Hb120-140g／L组相比，Hb〈100g／L组住院期间发生死亡的危险性为2．716，但经多因素分析后，其OR值无统计学意义。结论人院时血RBC计数和Hb水平可能不是AMI住院患者死亡的重要预示指标。Objective To examine the relationship between admission red blood celI（RBC） count and hemoglobin（Hb）and in-hospital death among patients with acute myocardial infarction（AMI）.Methods 849 patients with AMI were selected as study subjects,demographic data, biochemical indicators including RBC count and Hb and data on in-hospital death were collected for all subjects,relationship between admission RBC count and Hb and in-hospital death was analyzed with univariate and multivariate analysis methods. Results Admission RBC count and Hb were higher in the death cases than that in survival cases.By univariate logistic analysis,there was a significant association between admission RBC count and in-hospital death,but no significant association by multivariate logistic analysis.Unadjusted OR of death for the patients with Hb〈100g/L was 2.716 compared to those with Hb of 120 - 140g/L,but the OR was not significant after adjusted for multivariate. Conclusion Admission RBC count and Hb maybe not important predictors for death of patients with AMI.
