Anticoagulant Use Among the total AF population in this study, based on claims data, 9093 (35%) patients with AF received
anticoagulant treatment to reduce the risk for stroke and 16,617 (65%) did not (Table 3). Because the data used
in this analysis were collected only up to June 2010,newer oral anticoagulant agents were not included. Of the 9093 patients who received an anticoagulant, 4877 (54%) had a gap of ≥60 days in therapy. The mean time
from initiation of anticoagulation to interruption of therapy was 166 days.
