BACKGROUND AND PURPOSE: @entity1779 ( @entity1779 ) are associated with an increased risk of @entity1779 . The impact of oral anticoagulation (OAC) on @entity1779 is not well characterized. Our aim was to assess the prevalence of @entity1779 in @entity64 and @entity4905 ( @entity4905 ) @entity1 with @entity955 ( @entity955 ) and to analyze the implications of previous treatment with OAC. METHODS: In this retrospective analysis on data from a prospectively recruiting @entity64 registry, @entity1 with @entity64 or @entity4905 with brain magnetic resonance imaging including susceptibility weighted imaging were consecutively enrolled during a 3-year period. For each @entity1 cardiovascular risk factors, @entity955 history and recent diagnosis of @entity955 , present use of OAC and antiplatelets, the National Institute of Health @entity64 Scale and the premorbid modified Rankin Scale score were recorded. Two independent raters identified @entity1779 according to consensus criteria. CMB location was classified as lobar, deep or in the posterior fossa. RESULTS: In all, 785 @entity1 (mean age 63.9      14.2 years) were included. At least one CMB was detected in 186 (23.7%) @entity1 . @entity1779 were significantly more frequent in @entity1 with @entity955 (30.5% vs. 22.4%). @entity1 with previous OAC treatment were more likely to have @entity1779 (36.7% vs. 22.8%, P  =  0.03) and abundant @entity1779 (n  >  10) were more frequent in anticoagulated @entity1 even after adjustment for age. However, age was the only independent factor predicting @entity1779 (P  =  0.001). CONCLUSIONS: @entity1779 are common in elderly @entity955 @entity1 with acute @entity64 . Previous OAC is associated with a higher number of @entity1779 predominantly in the lobar location. Establishing a causal relationship requires prospective longitudinal investigation.
