文摘

Approximately 10 years have passed since intravenous (IV) recombinant tissue plasminogen activator therapy was approved in Japan. The aim of this retrospective study was to identify the effectiveness and safety of IV alteplase therapy with the Japanese original dose around Hiroshima via consideration of the patients' backgrounds, examination findings, and outcomes.

Methods

All consecutive patients with ischemic stroke who received IV alteplase therapy between October 2005 and October 2010 were registered.

Results

Four hundred twenty-nine patients with ischemic stroke (172 female [40.1%], mean age 73.7 ± 11.8 years) were registered. The proportion of patients over 75 years old was 51.5% (221 patients). The median National Institutes of Health Stroke Scale (NIHSS) scores at admission were 13 (interquartile range, 9-19), and the NIHSS scores 24 hours after alteplase infusion were 8 (interquartile range, 3-15). The proportion of intracerebral hemorrhage within the initial 36 hours was 20.2% (86 patients). After the multivariate regression analysis, a history of hypertension (odds ratio = 4.14; 95% confidence interval, 1.32-14.79; P = .01) and no recanalization (odds ratio = 10.10; 95% confidence interval, 3.03-39.33; P < .0001) were independently associated with a modified Rankin Scale (mRS) score of 2 or higher at 3 months. Patients over 75 years old were not significantly associated with an intracerebral hemorrhage within the initial 36 hours and an mRS score of 2 or higher at 3 months.

Conclusions

The results of our study demonstrated that IV alteplase therapy with the Japanese original dose was effective and exhibited a safety profile similar to other studies. Moreover, we should not hesitate to IV alteplase therapy simply because of advanced age.
