Abstract
Introduction
Known atrial fibrillation (AF) rate and appropriate prescription of oral anticoagulants (OACs) in acute ischemic stroke (AIS) patients with AF in China are not as well known as in Western countries.
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, including 103 female and 75 male patients), 154 of overall, 88 of female and 66 of male patients, respectively, were indicated to be taking OACs. 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 cerebral infraction (MCI; 43.0%, 148/344), the known AF rate was 65.5% (97/148). Among the MCI patients in the AF-known group with echocardiography results (61 patients), 50 patients had an OACs indication. However, only 22.0% (11/50) of these patients took OACs, and none met the guideline-based criteria for OACs.
Conclusions
This study revealed a low known AF rate, low OACs use rate and low rate of meeting the guideline-based criteria for OACs in AIS patients with AF in the northwest region of China. These findings indicated the importance of AF as a public health problem in China.
