Abstract
Background The benefit of periprocedural bridging with low-molecular-weight heparin (LMWH) in patients with atrial fibrillation has been contested by the publication of the BRIDGE trial.
Objective This article determines whether publication of the BRIDGE trial has led to less bridging procedures and better patient outcomes (i.e., a composite of thromboembolism, major bleeding, and death) in patients undergoing invasive procedures at the Leiden Anticoagulation Clinic, the Netherlands.
Methods We identified all procedures that required vitamin K antagonist interruption. Procedures were divided in a period before (2014–2016; 22 months) and after the publication of the BRIDGE trial (2016–2017; 22 months). Cumulative incidences 30 days postprocedure and relative risks of thromboembolic events, major bleeding, and mortality were calculated.
Results A total of 4,892 and 4,237 eligible procedures were performed in 2014 to 2016 and 2016 to 2017, respectively. The cumulative incidence of thromboembolism was 0.5% in 2014 to 2016 compared with 0.3% in 2016 to 2017; adjusted odds ratio (OR) 0.60 (95% confidence interval [CI] 0.30–1.21). The cumulative incidence of major bleeding was 1.0% in the 2014 to 2016 period as compared with 1.3% in the 2016 to 2017 period; adjusted OR was 1.27 (95% CI 0.85–1.90). The adjusted OR of the composite endpoint was 1.05 (95% CI 0.74–1.48). The frequency of bridging with LMWH (14.8% in 2014–2016 vs. 16.6% in 2016–2017) as well as mean CHA2DS2-VASc scores of patients receiving bridging did not change after publication of the BRIDGE trial.
Conclusion We showed that despite publication of the BRIDGE trial, the frequency of bridging with LMWH and patient outcomes regarding bleeding complications did not change.
