Of 73 patients with initial
lacunar stroke subsequently treated with
aspirin, 13 (18%) developed recurrent
stroke (11
lacunar infarcts and 2 nonlacunar
infarcts), and 4 (5%) died within 1 year. Of the
aspirin-treated
lacunar infarct patients, 58 received 325 mg or lower-dose
aspirin, and 15 received 600-1,300 mg of
aspirin. Thirteen
aspirin-treated patients who developed recurrent
ischemic stroke received 80 mg or 325 mg of
aspirin, whereas recurrent
stroke did not occur in 15 patients treated with 600-1,300 mg of
aspirin daily. Of 25 patients with
lacunar stroke who were subsequently treated with 250 mg of
ticlopidine twice daily, 1 patient (4%) developed recurrent
lacunar infarct, and none died within 1 year. Of 10 patients who had an initial
lacunar stroke and subsequently received no antiplatelet medication, 4 (40%) developed recurrent
lacunar stroke, and 1 (10%) died within 1 year.
