Abstract
Objective To explore the diagnostic value of white blood cell count and its classification in a-cute myocardial infarction.Methods A retrospective analysis was made on the clinical data of 195 cases under-going coronary angiography,which were divided into the case group and the control group.The case group was comprised of 60 cases of ST elevation acute myocardial infarction(STEMI)and 66 cases of non ST elevation myocardial infarction(NSTEMI)while 69 cases of non-acute myocardial infarction(AMI)were used as control group.White blood cell count and its classification were tested using Sysmex 2100.Troponin I(TNI)and B type of brain natriuretic peptide(BNP) were tested using Beckman DXI800.Blood glucose,blood lipids and myocardial enzymes were tested using Roche Cobas c701.Results White blood cell count(WBC),neutrophil count(N)and the ratio of neutrophil to lymphocyte(NLR) were all increased in both STEMI group and NSTEMI group compared with control group.And these indices were also higher in STEMI group than those in NSTEMI group.The largest area under the curve of ROC curve(AUC ROC) was observed when N was used for diagnosis of STEMI(AUC = 0.865;95% confidence interval 0.813 -0.917).Moreover,the ROC curve of combined N and TNI yields a larger AUC ROC than that of N and TNI being used individually (AUC=0.887 7;95% confidence interval 0.840 9 -0.934 5).Conclusion Neutrophil count has a high diag-nostic value in ST segment elevation acute myocardial infarction,and it is very useful in the classification of a-cute myocardial infarction.关键词
