| Summary: | Aim. To reveal the association of hereditary specifics of inflammatory factors with the adverse risk in atrial fibrillation (AF).Material and methods. Totally 258 patients studied (68,5±0,67 y. o.) with nonvalvular AF, recording the events as ischemic stroke, myocardial infarction, venous and arterial thromboembolism. Mean follow-up was 455±11,71 days.Results. Factors that are independently associated with ischemic stroke development in patients not receiving anticoagulants (n=101), were the allele C of polymorphic marker rs2228145(А/С) of gene IL-6 receptor (OR 13,25 CI 1,57112,18, р=0,018), age ?75 y. o. (OR 1,1, CI 1,008-1,2, р=0,032) and EF LV (OR 0,97 CI 0,94-0,99 р=0,027), with a “thrombotic endpoint” development — DM (OR 4,3 CI 1,46-12,45 р=0,008), EF LV (OR 0,96 CI 0,94-0,98, р<0,0001) and carriage of allele C of polymorphic marker rs2228145(А/С) of receptor to IL-6 gene (OR 4,03 CI 1,0715,26, р=0,04). There was no association with adverse outcomes in genes IL-6 polymorphisms as (G(-174)C and G(-572)C), ИЛ-10 (C(-819)T), ФНО (G(-238)A, G(-308)A and ФНО? rs180630). In those receiving adequate anticoagulant therapy (n=157) there was no significant association of IL-6 receptor gene polymorphism with adverse outcomes.Conclusion. Therefore, the carriage of allele C of polymorphic marker rs2228145(А/С) of the IL-6 receptor gene might be an independent risk marker for adverse outcome in non-valvular AF, potentially, being a selection tool for those patients not having enough high risk according to common scores. |
