PURPOSE: The relationship between response to clopidogrel and early neurological
deterioration (END) after acute ischemic stroke (IS) is not well defined. The aim
of present study was to evaluate the associations of clopidogrel resistance (CR)
with END, and stratified analyze the effectiveness of clopidogrel alone and
clopidogrel plus aspirin for the prevention of END. RESULTS: A total of 375
patients, 144 patients were received clopidogrel alone, 231 patients took
clopidogrel plus aspirin. CR occurred in 153 patients (40.8%). 95 (25.3%)
patients developed END within the first 10 days. Platelet aggregation was higher
on admission, and inhibition of platelet aggregation was significantly lower in
patients with END than patients without END. Diabetes mellitus, CR, and
clopidogrel plus aspirin were independently associated with END. Dual
antiplatelet therapy with aspirin and clopidogrel can inhibit both arachidonic
acid (AA)-induced and ADP-induced platelet aggregation. METHODS: This was a
prospective, two-center study. A total of 375 IS patients taking clopidogrel
alone or clopidogrel plus aspirin were enrolled. Platelet aggregation was
measured before and after the 7-10 day treatment. CR was assessed by adenosine
diphosphate (ADP)-induced platelet aggregation. The primary endpoint was END
within the 10 days after admission. The secondary endpoint was a composite of
recurrent ischemic stroke, myocardial infarction, and death during the 10 days
after admission. CONCLUSIONS: CR and END are fairly common after acute IS. CR is
associated with higher risk of END. Clopidogrel plus aspirin combination therapy
provides greater inhibition of platelet aggregation, and may afford protection
against END.
