Abstract:
Objective To investigate the predictive factors of no early improvement and their impact on outcomes after alteplase intravenous thrombolysis in patients with acute ischemic stroke.Methods Between March 2015 and March 2016,the clinical data of the patients with acute ischemic stroke admitted to the Department of Neurology,Fengcheng People's Hospital and treated with intravenous thrombolysis were analyzed retrospectively.The National Institutes of Health Stroke Scale score declined ＜4 within 24 h after admission was defined as no early improvement,and the modified Rankin Scale score ＞ 2 at 3 months was defined as poor outcome.Multivariate logistic regression analysis was used to determine predictors of no early improvement and their impact on outcomes.Results A total of 85 patients were enrolled,aged 63.88 ± 11.12 years,63 (74.1％) were males;45 (52.9％) had no early improvement,40 (47.1％) had early improvement;48 (56.5％) had good outcome at 3 months,and 37 (43.5％) had poor outcome.The proportion of hypertension (73.3％ vs.45.0％;x2 =7.083,P =0.008) and diabetes mellitus (33.3％ vs.15.0％;x2 =3.826,P =0.051),as well as the baseline fasting blood glucose (8.74 ± 4.28 mmol/L vs.6.87 ±2.57 mmol/L;t=2.471,P=0.016) in the no early improvement group were significantly higher than those in the early improvement group.Multivariate logistic regression analysis showed that hypertension alone was an independent risk factor for no early improvement after intravenous thrombolysis with ateplase (odds ratio 2.896,95％ confidence interval 1.108-7.570;P =0.030).The proportion of early improvement in the good outcome group was significantly higher than that in the poor outcome group (58.3％ vs.32.4％;x2=5.626,P=0.018).Multivariate logistic regression analysis showed that early improvement might be a independent predictor of good outcome (odds ratio 3.187,95％ confidence interval 1.099-9.242;P =0.033).Conclusion In patients treated with alteplase thrombolytic therapy,hypertension was an independent risk factor for no early improvement,and no early improvement was independently associated with poor outcome.
