Background: The efficacy and safety of statins for secondary prevention in patients who have experienced a cardioembolic stroke are not well-defined. However, previous observational data reported hyperlipidemia as a risk factor for both ischemic and bleeding complications in patients with AF and previous stroke. Based on these premises, we conducted a sub-analysis of the RAF and RAF-NOAC studies to evaluate the efficacy and safety of statins in secondary prevention in patients with acute ischemic stroke and AF. Methods: We combined patient data from the RAF and RAF-NOAC studies. We included consecutive patients with AF who suffered an acute ischemic stroke with a follow-up of 90 days. Our outcomes were the combined endpoint, including stroke, transient ischemic attack, systemic embolism, symptomatic intracerebral hemorrhage, and major extracranial bleeding. Furthermore, both ischemic and hemorrhagic outcomes were evaluated separately. Results: A total of 1.742 patients were included, 898 (52%) received statins after the index event. At multivariable analysis, statin use was statistically associated with age (OR 0.92, 95% CI 0.97 - 0.99, p = 0.001), male sex (OR 1.35, 95% CI 1.07 - 1.70, p = 0.013), anticoagulation (OR 2.53, 95% CI 1.90 - 3.36, p <0.0001), hyperlipidemia (OR 5.52, 95% CI 4.28 - 7.12, p <0.0001), paroxysmal AF (OR 1.40, 95% CI 1.12 - 1.75, p = 0.003), leukoaraiosis (OR 1.39, 95% CI 1.11 - 1.75, p = 0.004) and heart failure (OR 0.72, 95% CI 0.53 - 0.98, p = 0.034). Statin use was not associated with the combined outcome event (OR 0,81, 95% CI 0,56 ? 1,19, p = 0.286) and ischemic outcome event (OR 1,13, 95% CI 0,71 ? 1,82, p = 0.604) while was associated with a lower risk of hemorrhagic outcome event (OR 0,49, 95% CI 0,27 ? 0,88, p = 0.016). Conclusions: Statins seem to protect against global bleeding events in cardioembolic stroke patients; this may be due to the pleiotropic effect of statins.
