Abstract

Atrial fibrillation (AF) is an independent factor increasing the risk of an ischemic stroke (IS) fivefold. The objective of the study was to evaluate the frequency of coexistence of non-valvular AF and IS during the acute stroke and to analyze the attitude of AF patients to treatment.

The study included 3712 successive patients presenting either an IS or a transient ischemic attack.

The analysis revealed a significant increase in the rate of patients with AF and IS in the years 2010–2013 (31.9%) compared with 2002–2005 (20.2%). A rise in the proportion of AF and IS patients was recorded over the course of consecutive years in group II. The proportion of newly detected AF cases during hospital stay differed significantly between the groups (16.9% vs. 31.9%). Group I and II patients differed essentially with regards to hypertension incidence and female rates. Antiplatelet medications or OACs were taken by a significantly greater number of AF patients in group II. Low number of therapeutic levels of INR was recorded in both groups.

IS and AF coexist more frequently than indicated by previous assessments and demographic data from other countries. Increase in the number of IS and AF patients may result from higher detectability of AF and older age of patients affected with stroke, women in particular. Despite a well grounded knowledge about the benefits of OACs use in the prophylaxis of thrombotic-embolic events in AF patients, they are rarely used. A surprisingly low proportion of patients taking OACs reaches a therapeutic INR level.
