Low-dose urokinase combined with low-molecular weight heparin nadroparin calcium and ozagrel sodium in patients with acute cerebral infarction

Abstract

[Objective]To explore an individualized treatment measure enjoying more practical,effective and safe characteristics through evaluating the efficacy and safety of combined medications of low-dose urokinase,low-molecular weight heparin nadroparin calcium and ozagrel sodium in treating patients with acute cerebral infarction.[Methods]One-hunderd patients with acute cerebral infarction patients were recruited in this trail,and grouped according to different treatment times:Group A (n=40,from January 2005 to February 2008,being selected into the group in accordance with standards of China Guideline for Cerebrovascular Disease Prevention and Treatment) and Group B (n=60,from March 2008 to June 2011,being selected into the group in accordance with indications for onset time within 24 h and allowing age more than 75 years).Standard thrombolytic therapy (high dose urokinase) was performed on Group A and combined medications of low-dose urokinase,low-molecular weight heparin nadroparin calcium and ozagrel sodium (triple antithrombotic therapy) were performed on group B.National Institute of Health Neurological Deficit Scale (NIHSS) and Evaluation Standard of Clinical Efficacy were used to evaluate the recovery of neurological function before treatment and 24 h,7 and 14 d after treatment.[Results] NIHSS scores after therapy rapidly decreased in both groups as compared with those before treatment (P＜0.05).The NIHSS scores of Group B at 24 h,and 7 and 14 d after treatment were significantly decreased as compared with those of Group A (P＜0.05).The efficacy rate of Group B was significantly higher than that of Group A (P＜0.05).Intraparenchymal hemorrhage rate was 10.0％ (4/40) in Group A and 3.3％ (2/60) in Group B.[Conclusion] Triple antithrombotic therapy is more effective and relatively safer than standard thrombolytic therapy in treatment of patients with acute cerebral infarction.
