Insights
For patients with atrial fibrillation and coronary artery disease after percutaneous coronary intervention, one month of triple therapy followed by dual therapy is recommended. Tailoring antithrombotic therapy balances bleeding and ischemic risks.
Area of Science:
- Cardiology
- Pharmacology
- Interventional Cardiology
Background:
- Atrial fibrillation (AF) and coronary artery disease (CAD) often coexist.
- Percutaneous coronary intervention (PCI) is a common treatment for CAD.
- Antithrombotic therapy is crucial but complex in patients with both conditions post-PCI.
Purpose of the Study:
- To review current literature on antithrombotic therapy for AF patients post-PCI.
- To analyze optimal therapy type, duration, and strategies for elderly patients.
- To identify methods for reducing bleeding risk.
Main Methods:
- Literature search of major databases (PubMed, Web of Science, etc.).
- Inclusion of randomized controlled trials, meta-analyses, observational studies, and guidelines.
- Analysis of 236 retrieved publications, with 76 deemed relevant.
Main Results:
- Most guidelines recommend 1 month of triple therapy (oral anticoagulant + dual antiplatelet) followed by 11 months of dual therapy.
- Shorter dual antiplatelet therapy (≤6 months) may be safer with newer drug-eluting stents.
- In the elderly, dual therapy is often preferred over triple therapy due to bleeding risk.
Conclusions:
- Individualized antithrombotic therapy is essential, balancing ischemic and bleeding risks.
- For most AF patients post-PCI, 1 month of triple therapy followed by 11 months of dual therapy is recommended.
- Proton-pump inhibitors may benefit patients at high risk for gastrointestinal bleeding.
Aim:
The objective of this article is to review the contemporary literature on the use of antithrombotic therapy in patients with atrial fibrillation (AF) and coronary artery disease after undergoing percutaneous coronary intervention (PCI). Special consideration was given to the type and duration of therapy, treatment strategies for the elderly (≥65 years of age), and strategies to reduce bleeding.
Methods:
Relevant studies were searched through MEDLINE/PubMed, Web of Science, Cochrane Library, ClinicalTrials.gov, and Google Scholar. Of the 236 publications retrieved, 76 were considered relevant including 35 randomized controlled trials, 17 meta-analyses, 16 observational studies, and 8 published major guidelines.
Results:
Most trials, meta-analyses, and guidelines support 1 month of triple therapy (TT) with an oral anticoagulant (OAC), dual antiplatelet agents (DAPT) with aspirin (ASA)/clopidogrel, and, afterward, dual therapy (DT) with OAC and single antiplatelet agent for an additional 11 months, or alternatively DT alone for 12 months after PCI. Individual consideration is given to the risk and impact of stent thrombosis (ST), thromboembolism, and bleeding. Several trials and meta-analyses have also suggested that shorter DAPT duration (≤6 months) may be safer than longer therapy (≥6 months) when weighing the risk of bleeding with ischemic outcomes, especially with newer generation drug-eluting stents. The selective use of proton-pump inhibitors in patients prone to gastrointestinal bleeding who are subjected to prolonged exposure with TT or DT may be beneficial. In the elderly, the risk of bleeding from TT, compared with DT, outweighs the benefit of reducing ischemic events.
Conclusions:
In conclusion, tailoring therapy to the individual patient is recommended considering the ischemic and bleeding risk as well as the risk of thromboembolism. For most patients with AF, 1 month of TT and subsequently DT for additional 11 months are recommended.
