Background Despite doubts about their efficacy and concern abouttheir safety, antithrombotic agents are often used to treatacute ischemic stroke. Recent experience in patients with otherthromboembolic disorders suggests that low-molecular-weightheparin, which requires only subcutaneous administration onceor twice daily, may be more effective and safer than standard(unfractionated) heparin.
Methods We conducted a randomized, double-blind, placebo-controlledtrial comparing two dosages of low-molecular-weight heparinwith placebo in the treatment of ischemic stroke. Patients wererandomly assigned within 48 hours of the onset of symptoms toreceive high-dose nadroparin (4100 antifactor Xa IU twicedaily), low-dose nadroparin (4100 IU once daily), or placebosubcutaneously for 10 days. The primary measure of outcome wasdeath or dependency regarding activities of daily living sixmonths after randomization. Secondary outcomes were death, hemorrhagictransformation of the infarction, and other complications at10 days, and death or dependency at 3 months.
Results A total of 2750 patients were screened for the study.Among 312 patients randomized, 306 had outcomes that were analyzedat six months. Forty-five patients (45 percent) in the high-dosegroup, 53 patients (52 percent) in the low-dose group, and 68patients (65 percent) in the placebo group died or became dependent.There was a significant dose-dependent effect among the threestudy groups in favor of low-molecular-weight heparin (P = 0.005by the chi-square test for trend). No significant differencesamong the groups in the occurrence of secondary outcomes wereobserved at 10 days.
Conclusions For patients with ischemic stroke treated within48 hours of the onset of symptoms, low-molecular-weight heparinwas effective in improving outcomes at six months.
