Popis: | Objectives: To determine whether current influenza vaccination is associated with reduced risk of major vascular events in patients with recent ischemic stroke or TIA of mainly atherothrombotic origin. Methods: Data were pooled from 2 prospective cohort studies, the OPTIC Registry (n = 3,635) and the AMISTAD Study (n = 618), and from the randomized PERFORM Trial (n = 19,120), all of which included patients with recent ischemic stroke or TIA. Influenza vaccination status was determined in 23,110 patients. The primary outcome was a composite of nonfatal myocardial infarction, nonfatal stroke, or vascular death up to 2 years. Secondary outcomes were myocardial infarction and stroke separately. Results: Influenza vaccination had no association with the primary outcome in the propensity score–matched cohort (hazard ratio 0.97, 95% confidence interval [CI] 0.85–1.11; p = 0.67) or in the propensity score–adjusted cohort (hazard ratio 1.00, 95% CI 0.89–1.12; p = 0.99). Similarly, the risk of stroke and myocardial infarction did not differ between the vaccinated group and the unvaccinated group; in the matched cohort, the hazard ratio was 1.01 (95% CI 0.88–1.17; p = 0.89) for stroke and 0.84 (95% CI 0.59–1.18; p = 0.30) for myocardial infarction. Conclusions: Influenza vaccination was not associated with reduced outcome events in patients with recent atherothrombotic ischemic stroke after considering all baseline characteristics (including concomitant medications) associated with influenza vaccination. |
