概要 BACKGROUND: Atrial fibrillation (AF) includes paroxysmal and sustained (persistent or permanent) AF, and both forms are considered risk factors for ischemic stroke. This study aimed to investigate the differences in stroke severity at admission between patients with paroxysmal AF and sustained AF when treated with direct oral anticoagulants (DOACs). METHODS: Using data from DOAC-treated 300 nonvalvular patients with AF and acute anterior circulation stroke who were registered in the Multicenter Prospective Analysis of Stroke Patients Taking Oral Anticoagulants study, patients were divided into two groups, namely, paroxysmal AF and sustained AF. We compared the clinical characteristics between the two groups and determined the effect of these two types of AF on stroke severity on admission. RESULTS: Of 300 patients, 246 (males, n = 149; median age, 80 years) and 54 (males, n = 32; median age, 78 years) were assigned to the sustained AF and paroxysmal AF groups, respectively. The sustained AF group had a higher proportion of severe stroke (National Institutes of Health Stroke Scale score, >20) on admission (22.0% vs. 5.7%, p = 0.006) and internal carotid artery occlusion (11.4% vs. 1.9%, p = 0.03) compared to the paroxysmal AF group. Multivariate analysis showed that sustained AF was independently associated with severe stroke on admission (odds ratio 4.31, 95% confidence interval 1.24-15.0, p = 0.02). CONCLUSIONS: Sustained AF was associated with a higher severity of stroke accompanied with major vessel occlusion than paroxysmal AF, even prior to DOACs treatment.
