文摘

Gender differences in the use of recombinant tissue-type plasminogen activator (r-tPA) in stroke are complicated. In this study, we investigated gender differences using r-tPA exclusion criterion in a stroke population.

Methods

We analyzed the data from ischemic stroke patients aged 18 years or older from the Greenville Health System stroke registry on r-tPA administration between January 2010 and December 2013. We identified exclusion criterion and used specific clinical factors to determine gender differences in stroke patients receiving r-tPA.

Results

Of the 633 patients who were eligible to receive r-tPA, less than half received r-tPA (n = 241) whereas 422 were not able to receive r-tPA. Of the 241 patients who received r-tPA, 49.4% were female and 50.6% were male. Of the 422 patients who did not receive r-tPA, more women (235) were excluded from r-tPA than men (187) (P < .05). There were no gender differences in warning signs and contraindications in female versus male stroke patients (P > .005). There were however gender differences in age group as more women (38%; n = 235) were more likely to be excluded if they are more than 80 years old than men (19%, n = 187).

Conclusions

Within a large stroke population, exclusion criteria for r-tPA in women and men were similar with regard to race, initial National Institutes of Health Stroke Scale score, warning signs, and contraindications, but were different in the age group population exclusion criterion for intravenous r-tPA. We observed that intracerebral hemorrhage and match on computed tomography perfusion/magnetic resonance imaging or visible infarct greater than one third of the middle cerebral artery distribution were absolute criteria for exclusion.
