Abstract：Objective To analyze the value of neutrophil to lymphocyte ratio in prediction of in-hospital adverse events in patients with aortic dissection.Methods Clinical data of 504 patients with aortic dissection admitted to Beijing Anzhen Hospital,Capital Medical University from January 2012 to December 2014 were retrospectively analyzed.According to the mean value of NLR,the patients were divided into high NLR group(n =183,NLR≥7.70) and low NLR group (n =321,N LR ＜ 7.70).Risk factors of in-hospital adverse events were analyzed.Results Hypertension history rate,white blood cell count,neutrophil count,rates of acute and type A aortic dissection in high NLR group were higher than those in low NLR group;lymphocyte count,red blood cell count and platelet count in high NLR group were lower than those in low NLR group;the differences were significant (all P ＜0.05).Among patients with type A aortic dissection,incidence of in-hospital adverse events in high NLR group was significantly higher than that in low NLR group [24.8％ (33/133) vs 15.5％ (31/200)] (P =0.035).Among patients with type B aortic dissection,incidence of in-hospital adverse events showed no significant difference between groups (P ＞ 0.05).Logistic regression indicated that NLR was an independent risk factor of in-hospital adverse events in patients with type A aortic dissection (odds ratio =2.752,95％ confidence interval:1.043-7.262,P =0.041).Conclusion NLR is an independent predictor of in-hospital adverse events in patients with type A aortic dissection.
