| Objective:To analyze the relationship between white blood cell count or other factors and no-reflow phenomenon after emergency PCI for acute myocardial infarction.Methods:The Clinical and coronary angiographic data of 440 patients with ST Elevation Myocardial Infarction complicated with emergency PCI were selected from the general hospital of Ningxia university from February 2016 to February 2017.The patients were divided into two groups,with the anterior coronary blood flow less than or equal to TIMI flow grades of 2 as the criterion of no-reflow and TIMI 3 flow is defined as normal flow.52patients were enrolled in the no-reflow group and 388 patients in the normal flow group.The relationship between white blood cell count or other factors and no-reflow after emergency PCI for acute myocardial infarction was analyzed by x~2 test,T test and Logistic regression.Results:x~2 test and T test showed that age,gender,the time from myocardial infarction to vessel opening,arrhythmia,diabetes,glycosylated hemoglobin,Killip?2,white blood cell count,absolute neutrophil value and brain natriuretic peptide were significantly different between the no-reflow group and the normal flow group(P<0.05).Univariate Logistic regression analysis showed that except the absolute value of neutrophils,the other 9 factors were related to no-reflow.Multivariate Logistic regression analysis showed that white blood cell count(OR:1.116;95%CI:1.029-1.211),myocardial infarction to vessel opening time(OR:1.092;95%CI:1.008~1.182)and age(OR:1.049;95%CI:1.013-1.086)were independent risk factors of no-reflow(P<0.05).Conclusion:1.The increase of the white blood cell count at admission was positively correlated with no-reflow after emergency PCI for acute myocardial infarction,and was an independent risk factor of no-reflow;2.The time from myocardial infarction to vessel opening and age are also risk factors of no-reflow. |
