Aims: This study aimed to (1) define the prevalence of vascular disease (VD; coronary (CAD) and/or peripheral artery disease (PAD)) and associated risk factors in patients with atrial fibrillation (AF); (2) establish the relationship of VD and associated treatment patterns on adverse events in AF.
Methods: Data from 701 Polish AF patients enrolled in the EORP-AF General Long-Term Registry in the years 2013-2016 were included in this analysis. During the one-year follow-up, the occurrence of major adverse events (MAE; all-cause death, thromboembolic event, myocardial infraction) and its components was evaluated.
Results: VD was recorded in 293 (44%) patients and based on multivariate logistic analysis was associated with age >75, diabetes, hypercholesterolemia, heart failure (HF). There was no significant difference in rates of MAE between patients with and without VD based on Fisher's exact test (8.8% vs 5.7%, P = .16), as well as between patients with concomitant CAD and PAD, PAD and CAD alone based on the Chi-square test (21% vs 7.5% vs 6.7%; P = .09). A higher risk of MAE was associated with HF, chronic kidney disease (in all study group), age >75, HF, diabetes (VD group),chronic obstructive pulmonary disease (non-VD group) based on the multivariate logistic analysis. Relative to patients with VD on vitamin K antagonists (VKA), those treated with non-VKA-oral anticoagulants (NOAC) had lower absolute rate of MAE according to Fisher's exact test (1.4% vs 10%, P = .02) but similar risks for thromboembolic and hemorrhagic events. The concomitant use of triple therapy was associated with increased risk of MAE as compared with those on OAC alone or dual therapy based on the Chi-square test (20% vs 4.8%, 3.2%, P = .02).
Conclusion: VD was prevalent in almost two-fifths of AF patients. The incidence of MAE was higher in patients with VD on VKA (vs NOAC) and on triple therapy (vs dual therapy, OAC alone) within one-year follow-up.
