Abstract
AIMS:The risks of thromboembolism and bleeding in patients with atrial fibrillation (AF) and valvular heart disease (VHD) are sparsely described. We described the risk of events in non-anticoagulated and anticoagulated patients with AF and VHD according to the EHRA classification, EHRA Type 1 and Type 2 VHD, and within subgroups of EHRA Type 1 and Type 2 VHD. METHODS AND RESULTS:Cohort study of AF patients with coexisting VHD, identified in nationwide Danish registries from 2000-2018. Risk of thromboembolism and bleeding after 1 year of follow-up were calculated in each group. We identified 28,770 incident AF patients with VHD. Not surprisingly, we observed the highest risks of thromboembolism in the non-anticoagulated AF patients with EHRA Type 1 and Type 2 VHD (4.9% vs. 2.6% and 3.2% vs. 1.9%) and the highest risks of bleeding in the anticoagulated AF patients with EHRA Type 1 and Type 2 VHD (6.6% vs. 4.3% and 6.1% vs. 4.9%). However, within the subgroups of AF patients with EHRA Type 1 and Type 2 VHD, we observed a large proportion of non-anticoagulated patients (32.9-49.2%), despite a CHA2 DS2 -VASc score of 2≤ in the majority of these patients (81.9-95.6%). CONCLUSIONS:When using data reflecting contemporary clinical practice, we observed markedly different risks of thromboembolism and bleeding in EHRA Type 1 and Type 2 VHD. Additionally, we observed a potential underuse of oral anticoagulation within the subgroups of AF patients with EHRA Type 1 and Type 2 VHD, underlining need for further attention on this patient group.
