Abstract
OBJECTIVES: Edaravone, a free radical scavenger, alleviates blood-brain barrier disruption in conjunction with suppression of the inflammatory reaction in acute cerebral infarction. Thrombolysis with recombinant tissue plasminogen activator (rtPA) is an established therapy for acute cerebral infarction patients. The purpose of this study was to assess the effects of edaravone on outcomes in acute cerebral infarction patients treated with ultra-early thrombolysis of iv-rt-PA. PATIENTS AND METHODS: We conducted a retrospective cohort study using the database of Ningbo First Hospital. We identified patients who were admitted with a primary diagnosis of acute cerebral infarction and treated with intravenous rtPA(iv-rtPA) within 3 h of symptom onset from March 1st in 2014 to October 31st in 2016.Thenceforth,the patients were divided into 2 groups by treatment with(edaravone group) or without edaravone(non-edaravone group). Glasgow Coma Scale (GCS) scores and mRS score at admission were used. Clinical background, risk factors for acute cerebral infarction hemorrhagic transformation, 7-day mortality, recanalization rate, bleeding complications and blood rheology indexes were collected. We also collected the following factors: National Institutes of Health Stroke Scale scores, barthel index. RESULTS: 136 patients treated without edaravone during hospitalization were selected in non-edaravone group while edaravone group included 132 patients treated with edaravone during hospitalization. The patient baseline distributions were well balanced between non-edaravone group and edaravone group. The rate of hemorrhagic transformation in non-edaravone group was higher than that in edaravone group (P ＜ 0.05). The NIHSS scores 7 days and 14 days after symptom onset were higher in non-edaravone group than in edaravone group (both P ＜ 0.05). Edaravone group showed a higher recanalization rate and a lower bleeding complications rate at discharge than the non-edaravone group (both P ＜ 0.05). The differences of all the blood rheology indexes between the two groups were statistically significant (all P ＜ 0.05). CONCLUSIONS: Edaravone may improve outcomes of acute cerebral infarction patients treated with ultra-early thrombolysis of iv-rt-PA.
