To assess the efficacy of intravenous recombinant tissue plasminogen activator (rt-PA) thrombolysis on clinical outcomes and risk of death in patients with acute cerebral infarction. Patients (n = 258) with acute cerebral infarction, treated within 4–5 h of the episode, were grouped according to whether intravenous thrombolysis was performed using rt-PA or not. Both groups received routine treatment for cerebral infarction, but the former received rt-PA intravenously at a dosage of 0.9 mg/kg. The National Institutes of Health Stroke Scale (NIHSS) score, clinical efficacy, and risk of bleeding and death were compared between the two groups. The NIHSS score and clinical effects for the rt-PA group were more favorable than those of its counterpart (P < 0.05), though there was no significant difference in risk of an intracranial hemorrhage. The mortality rate for the rt-PA group was lower than that of the control group (P < 0.05). Administration of intravenous rt-PA thrombolysis within 4.5 h of an acute cerebral infarction had a significant impact and did not increase risk of intracranial hemorrhage or death.
