Abstract
Background: There is no validated tool to assess patients' knowledge of oral anticoagulant therapy in atrial fibrillation in China. Methods: Using a standard translation program, the Jessa Atrial fibrillation Knowledge Questionnaire (JAKQ) was translated into Chinese. The reliability of the JAKQ was assessed by internal consistency (Cronbach's α coefficient), repeatability (test-retest reliability), and sensitivity tests. Effectiveness was assessed by hypothesizing that a lower JAKQ score was a risk factor for bleeding. A total of 447 patients with atrial fibrillation (AF) who were hospitalized between July 2019 and December 2021 were studied and followed up. Participants were followed up 1, 3, 6, and 12 months after enrollment. Bleeding during follow-up was recorded. Data were obtained from hospital databases and telephone follow-up. Result: A total of 447 patients with AF completed JAKQ. The mean age of patients was 67.7 ± 10.2 years. The median JAKQ score was 31.3% (12.5-43.8). The Cronbach's α coefficient of JAKQ was 0.616-0.637, and the test-retest reliability value was 0.902 (p < 0.001). Multivariate logistic regression showed that the higher knowledge level of AF was associated with secondary education or above, an income of more than 2000 yuan, and a history of AF of more than 1 year. Bleeding was associated with a lower JAKQ score, hypertension, and a history of bleeding. Non-bleeding patients on VKA had a better understanding of how often INR should be monitored and what to do if an OAC dose was missed. Conclusion: The Chinese version of JAKQ shows good reliability and validity, indicating that it is a valuable tool for AF and oral anticoagulation (OAC) knowledge assessment. It can be used in clinical practice to guide educational activities and improve the effectiveness and safety of treatment. It was shown that Chinese patients with AF have insufficient knowledge about AF and OAC. Lower JAKQ scores are associated with bleeding, so targeted education is necessary. Targeted educational efforts should focus on patients recently diagnosed with AF and those with lower formal education and income.

Abstract
Objective Limited data exist regarding the comparative detailed clinical characteristics of patients with ischemic stroke (IS)/transient ischemic attack (TIA) and intracerebral hemorrhage (ICH) receiving oral anticoagulants (OACs). Methods The prospective analysis of stroke patients taking oral anticoagulants (PASTA) registry, a multicenter registry of 1,043 stroke patients receiving OACs [vitamin K antagonists (VKAs) or non-vitamin K antagonist oral anticoagulant (NOACs)] across 25 medical institutions throughout Japan, was used. Univariate and multivariable analyses were used to analyze differences in clinical characteristics between IS/TIA and ICH patients with atrial fibrillation (AF) who were registered in the PASTA registry. Results There was no significant differences in cardiovascular risk factors, such as hypertension, diabetes mellitus, dyslipidemia, smoking, or alcohol consumption (all p>0.05), between IS/TIA and ICH among both NOAC and VKA users. Cerebral microbleeds (CMBs) [odds ratio (OR), 4.77; p<0.0001] were independently associated with ICH, and high brain natriuretic peptide/N-terminal pro B-type natriuretic peptide levels (OR, 1.89; p=0.0390) were independently associated with IS/TIA among NOAC users. A history of ICH (OR, 13.59; p=0.0279) and the high prothrombin time-international normalized ratio (PT-INR) (OR, 1.17; p<0.0001) were independently associated with ICH, and a history of IS/TIA (OR, 3.37; 95% CI, 1.34-8.49; p=0.0101) and high D-dimer levels (OR, 2.47; 95% CI, 1.05-5.82; p=0.0377) were independently associated with IS/TIA among VKA users. Conclusion The presence of CMBs, a history of stroke, natriuretic peptide and D-dimer levels, and PT-INR may be useful for risk stratification of either IS/TIA or ICH development in patients with AF receiving OACs.

Abstract
BACKGROUND Prescriptions of off-label under- and overdosing of direct oral anticoagulants (DOACs) are common for patients with atrial fibrillation, but their efficacy and safety remain unknown. METHODS Databases were searched for randomized controlled trial or adjusted observational study that compared an off-label versus on-label dosing of DOACs through June 15, 2021. The primary efficacy outcome was ischemic stroke/system embolism (IS/SE), and primary safety outcome was major bleeding. Net clinical outcome was generally defined as the composite of IS/SE, major bleeding, and all-cause death. Hazard ratios (HRs) with 95% CIs were pooled with random-effects models with Hartung-Knapp-Sidik-Jonkman method for adjustment. RESULTS Sixteen studies with 130 609 patients were included. Compared with on-labeling dosing, off-label underdosing of DOACs was associated with a higher risk of IS/SE (HR, 1.22 [95% CI, 1.05-1.42], P=0.01). The incidence of major bleeding was similar (HR, 0.95 [95% CI, 0.82-1.11], P=0.48). Off-label underdosing was associated with a higher risk of net clinical outcome (HR, 1.19 [95% CI, 1.04-1.40], P=0.04) and all-cause death (HR, 1.24 [95% CI, 1.04-1.48], P=0.02). Stratified analysis of off-label underdosing of DOACs for IS/SE showed subgroup differences among different DOAC types and study regions. Limited data showed that off-label overdosing was associated with a higher risk of IS/SE (HR, 1.26 [95% CI, 1.11-1.43], P=0.003) and major bleeding (HR, 1.30 [95% CI, 1.04-1.62], P=0.025). CONCLUSIONS Compared with on-label dosing, off-label underdosing of DOACs increased the risk of thromboembolic events but did not decrease the risk of bleeding. Limited data for off-label overdosing showed higher risks of thromboembolic and bleeding. Further studies are warranted to confirm the results of off-label overdosing DOACs and subgroup results of underdosing DOACs.
