Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Life-long therapy with oral anticoagulants (OAC) is strongly recommended in AF patients receiving left atrial appendage isolation (LAAI) to prevent thromboembolic (TE) events. However, some patients are observed to remain stroke-free while off OACs for years whereas others experience TE events if OAC is discontinued even for a short period of time. Therefore, we aim to evaluate the association of genetic variants (single nucleotide polymorphisms - SNPs) with off-anticoagulation stroke-risk in AF patients.
