摘要

In a double-blind, randomised trial, adding clopidogrel to aspirin after a minor ischaemic stroke or transient ischaemic attack reduced the risk of recurrent ischaemic stroke, but had no demonstrated effect on mortality or disability. After one month of dual therapy, the incidence of ischaemic events (mainly strokes) fell from 5.8% with aspirin alone to 3.9% with dual therapy. Increasing the duration of clopidogrel administration to 3 months did not result in any greater efficacy whereas it increased the risk of haemorrhage. Low dose aspirin is the first-choice antithrombotic after an ischaemic stroke or a transient ischaemic attack (TIA), in the absence of prosthetic valves or heart disease predisposing to embolism (1). A randomised trial in 5170 patients showed that adding clopidogrel to aspirin (two antiplatelet drugs) for the 3 weeks following a stroke appeared to prevent a few recurrences, but had no demonstrated effect on mortality and did not increase the risk of major bleeding events (1). Another trial of clopidogrel versus placebo in addition to aspirin, with a slightly different protocol, in particular a longer duration of dual therapy, has provided further information.
