Statin use and stroke outcomes in the Heart and Estrogen–Progestin Replacement Study (HERS)

The authors investigated the relationship between statin use and the risk of stroke in the Heart and Estrogen–Progestin Replacement Study (HERS). Despite large reductions in relative risk point estimates, statin use was not associated with differences in the risks of all fatal stroke (relative hazard [RH] 0.52, 95% CI 0.23 to 1.18, p = 0.12), fatal ischemic stroke (RH 0.51, 95% CI 0.18 to 1.45, p = 0.21), fatal hemorrhagic stroke (RH 0.18, 95% CI 0.02 to 1.46, p = 0.11), or TIA (RH 1.32, 95% CI 0.84 to 2.09, p = 0.23).
