Abstract:
Objective:To analyze the risk factors for early neurological deterioration(END)in elderly patients with acute ischemic stroke(AIS)after intravenous thrombolysis.Methods:Clinical data of 118 patients with AIS who had received thrombolysis were collected retrospectively.According to the occurrence of END, cases were divided into the END group(n=28)and the non-END group(n=90). Univariate analysis was used to compare general characteristics, clinical data, laboratory test results, TOAST classification, infarct location, and degree of culprit vessel stenosis between the two groups.Multivariate Logistic regression analysis was used to analyze the related factors for END.Results:Univariate analysis showed that the proportion of patients with diabetes mellitus and previous cerebral infarction was higher in the END group than in the non-END group( χ2=4.000 and 8.056, P=0.046 and 0.005). There were significant differences in National Institutes of Health Stroke Scale(NIHSS)score, time from onset to thrombolysis, thrombolysis time, swallowing dysfunction, albumin, leukocyte count, neutrophil count, lymphocyte count, glycosylated hemoglobin(HbA1c), creatinine, total cholesterol(TC), low density lipoprotein cholesterol(LDL-C), high density lipoprotein cholesterol(HDL-C)and lipoprotein(a)levels between the two groups(all P<0.05). There were also significant differences between the two groups in TOAST classification, infarct location and degree of culprit vessel stenosis( χ2=13.109 and 9.509, Z=2.912, P=0.004, 0.023 and 0.004). Multivariate Logistic regression analysis showed that NIHSS score, HbA1c, cardiogenic stroke, degree of culprit vessel stenosis and leukocyte count on admission were independent risk factors for END( OR=1.122, 2.131, 1.965, 1.876 and 1.563, P=0.036, 0.024, 0.028, 0.030 and 0.041). Conclusions:NIHSS score, HbA1c, cardiogenic stroke, degree of culprit vascular stenosis and leukocyte count on admission are independent risk factors for END, which should be closely monitored and managed with well formulated preventive measures in order to improve the prognosis of AIS patients.
