RelationshipEvaluation of Long-term Antithrombotic Management for Atrial Fibrillation Patients with a History of Coronary Stent Implantation
Main Article Content
Abstract
Purpose: American expert consensus publications recommend discontinuation of antiplatelet agents 6 to 12 months after Percutaneous Coronary Intervention (PCI) in patients with Atrial Fibrillation (AF) who require chronic anticoagulation, and use of oral anticoagulant monotherapy thereafter. This study aimed to assess real-world long-term antithrombotic therapy management practices and factors associated with the continuation of antiplatelet agents past 12 months post-PCI in patients with AF requiring chronic anticoagulation.
Methods: Patients with AF and a history of PCI greater than 12 months before their most recent encounter with physicians at an outpatient electrophysiology clinic were identified by chart review. Patient demographics, clinical characteristics, and current antithrombotic regimen were collected from encounters that occurred between July 2019 and June 2022. The independent predictive factors associated with the continuation of antiplatelet agents were identified using univariate and regression analyses.
Results: Out of 66 patients, 67% continued antiplatelet therapy for greater than 12 months post-PCI. Patients on antiplatelets were significantly less likely to have bare metal stents (p = 0.006), be greater than five years post-PCI (p = 0.002), and have a HASBLED score of two or less (p = 0.028) when compared to patients on oral anticoagulant monotherapy. Bare metal stent history (p = 0.045) and HASBLED score of two or less (p = 0.016) were also significant in regression analysis.
Conclusion: This study found that most patients with AF and a history of PCI continued antiplatelet therapy longer than 12 months post-PCI, often despite the high bleeding risk.
