Methods: Known AF and unknown AF, rate and adequacy of OACs use of AIS patients with AF attending five hospitals from April 2018 to August 2019 in the northwest region of China were investigated. Results: A total of 344 patients were enrolled. Of these, 237 (AF-known group; 237/344, 68.9%) and 107 patients (AF-unknown group; 107/344, 31.1%) were diagnosed with AF before and after AIS during this hospitalization, respectively. In the AF-known group with echocardiography results (178 patients, includT. Fan Department of Neurology, Xi’an Gaoxin Hospital, Xi’an, China G.

However, the actual OACs proportion was much lower [overall (30.5%, 47/154); female (31.8%, 28/88) and male (28.8%, 19/66) patients] than indicated. Only one female patient met the guideline-based criteria for OACs. As for patients diagnosed with massive cer
