白细胞与钾离子联合辅助诊断及治疗急性ST段抬高型心肌梗死的研究

目的探讨白细胞和钾离子在急性ST段抬高型心肌梗死的诊断及急性期治疗中的作用。方法选取2008年1月至2011年12月沧州市人民医院收治的心肌梗死患者105例,根据ST段是否升高分为ST段抬高组(55例)和非ST段抬高组(50例),另外选取40例健康体检者作为正常对照组,比较三组受试者白细胞和钾离子的情况及其与病情的关系。结果与正常对照组及非ST段抬高组患者相比,ST段抬高组白细胞数计数显著增高,钾离子水平显著下降(P<0.05)。ST抬高组患者的病死率、心力衰竭发生率、心脏病复发率均显著高于非ST抬高组,差异均有统计学意义(P<0.05)。结论 ST段抬高心肌梗死患者入院时白细胞计数及钾离子水平,对于患者的诊断、治疗及预后评估具有重要的价值,可以作为ST段抬高型心肌梗死的关键指标。

Study on the Effect of White Blood Cells Combined with Potassium Ion on the Supplementary Diagnosis and Treatment for Acute ST Segment Elevation Myocardial Infarction

Objective To explore the effect of the leukocytes and potassium ions on the diagnosis and treatment in the acute period for acute ST segment elevation myocardial infarction.Methods A total of 105 cases of patients with myocardial infarction admitted in Cangzhou People＇s Hospital from Jan.2008 to Dec.2011 were divided into ST segment elevation group（55 cases） and non ST segment elevation group（50 cases）,and another 40 cases of healthy patients underwent physical examination were selected as normal control group,levels of white blood cells and potassium ions of the three groups and their relationship with the disease were compared.Results Compared with normal control group and non ST segment elevation group,the number of white blood cell of ST segment elevation group increased significantly,and potassium ion concentration significantly decreased （P ＜ 0.05）.The mortality rate,incidence of heart failure,heart disease recurrencerate of ST elevation group were significantly higher than those of non ST elevation group,the differences were statistically significant（P ＜ 0.05）.Conclusion White blood cell count and potassium level of patients with ST elevation myocardial infarction on admission have important value for the diagnosis,treatment and prognosis of the patients,which can be used as key indicators of ST segment elevation myocardial infarction.
