Ticagrelor plus aspirin lowers risk of recurrent stroke, death vs aspirin alone

Posted on

In this randomized, placebo-controlled, double-blind trial, 11,016 patients with a prior mild-to-moderate acute noncardioembolic ischemic stroke, with a National Institutes of Health Stroke Scale (NIHSS) score of <5 or transient ischemic attack (TIA).and who were not undergoing thrombolysis or thrombectomy, were randomized to receive a 30-day regimen of ticagrelor plus aspirin (n = 5523) or aspirin (n = 5493) within 24 hours of the start of symptoms.

Stroke or death occurred in 5.5% of patients taking ticagrelor in combination with aspirin compared with 6.6% of patients taking aspirin alone (HR = 0.83; 95% CI, 0.71-0.96, P = 0.02).

Ischemic stroke occurred in 5.0% of patients taking ticagrelor in combination with aspirin compared with 6.3% of patients taking aspirin alone (HR = 0.79; 95% CI, 0.68 to 0.93; P = 0.004).

The incidence of disability was not significantly different between the groups.

Severe bleeding occurred in 0.5% and 0.1% of patients in the ticagrelor plus aspirin group and the aspirin group, respectively.
