In patients receiving 0.6 mg/kg alteplase, the outcome and the incidence of sICH were comparable to published data for 0.9 mg/kg. These findings indicate that alteplase, when administered at 0.6 mg/kg to Japanese patients, might offer a clinical efficacy and safety that are compatible with data reported in North America and the European Union for a 0.9 mg/kg dose 1).
Medical records were collected from patients suffered from AIS between 2010 and 2013 and allocated into either the intravenous recombinant tissue plasminogen activator (as rt-PA group) treatment, or non-rt-PA treatment group (as control group). The primary outcomes included a proportion of patients with favorable outcome [as defined with a modified Rankin Scale (mRS) of 0-1], functional independence (mRS of 0-2) or with bad outcome (mRS of 5-6) at 3, 6 and 12 months and the overall mortality. The secondary outcome included the events of intracranial hemorrhage. A total of 357 patients from Xinhua Hospital were selected. At 3-month follow-up, 86 patients in rt-PA vs. 99 in control group had favorable outcome, 105 vs. 122 were independent and 23 vs. 27 had bad outcome. At 6-month follow-up, 101 patients in rt-PA vs. 104 in control group had favorable outcome, 114 vs. 124 were independent and 20 vs. 34 had bad outcome. At 12 months, 104 patients in rt-PA vs. 105 in control group had favorable outcome, 117 vs. 125 were independent and 12 vs. 32 had bad outcome. At the end of 12 months, more deaths occurred in control group (20) than in the rt-PA group (11), but it was not statistically significant. Alteplase treatment in AIS patients showed the superior primary outcomes compared with control group, especially during the middle/long follow-up 2).
