Antithrombotic Therapy for Atrial Fibrillation and Coronary Disease de-Mystified

Publication date: Available online 20 August 2018Source: Canadian Journal of CardiologyAuthor(s): Jason G. Andrade, Marc W. Deyell, Graham C. Wong, Laurent MacleABSTRACTAtrial fibrillation (AF) is a progressive chronic disease characterized by exacerbations and periods of remission. It is estimated that up to 20-30% of those with AF also have coronary artery disease (CAD), and 5-15% will require percutaneous coronary intervention (PCI). In patients with concomitant AF and CAD, management remains challenging and requires a careful and balanced assessment of the risk of bleeding against the anticipated impact on ischemic outcomes (AF related stroke and systemic embolism, as well as ischemic coronary events). Oral anticoagulation (OAC) is indicated for the prevention of AF-related stroke and systemic embolism, whereas antiplatelet therapy is indicated for the prevention of coronary events. Each offers a relative efficacy benefit (e.g. dual antiplatelet therapy [DAPT] is more effective than OAC alone in reducing cardiovascular death, myocardial infarction, stent thrombosis, and ischemic coronary events in an ACS population), but with a relative compromise (e.g. DAPT is significantly inferior to OAC for the prevention of stroke/systemic embolism in an AF population at increased risk of stroke). The purpose of this review is to explore the current evidence and rationale for antithrombotic treatment strategies in patients with both AF and CAD. Specifically, there is a focus on how t...

AbstractTriple anti-thrombotic therapy combining oral anticoagulation and dual anti-platelet therapy following percutaneous coronary intervention in patients with atrial fibrillation was considered as standard and recommended by guidelines. While bleeding risk is considerable with that approach, data for efficacy are scare. Several trials assessed the possibility of reducing anti-thrombotic treatment by mainly shortening the exposure to acetylsalicylic acid. Dropping one of the anti-platelet components might increase the risk of stent thrombosis, myocardial infarction or stroke. Despite that fear, the recent trials ’...

This study evaluated the benefit of dual therapy in reducing ischemic events in atrial fibrillation (AF) patients presenting with acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI). We searched PubMed, Cochrane Library, and ClinicalTrials.gov for randomized controlled trials (RCTs) comparing dual and triple therapies (oral anticoagulation plus aspirin and P2Y12 inhibitor) for AF patients with ACS or those undergoing PCI. The composite primary outcome included all-cause death, myocardial infarction (MI), stent thrombosis (ST), or stroke. Relative risk (RR) and the corresponding 95% confiden...

Conclusion: In adults with AF after PCI, dual therapy reduces risk for bleeding compared with triple therapy, whereas its effects on risks for death and ischemic end points are still unclear. Primary Funding Source: None. PMID: 32176890 [PubMed - as supplied by publisher]

gro G Abstract Background: Combination of dual antiplatelet (DAPT) and oral anticoagulation therapy is required to decrease cardioembolic stroke and stent thrombosis risk in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS). We compared the safety and efficacy of dabigatran etexilate with vitamin K antagonist (VKA), in combination with DAPT (aspirin plus clopidogrel) treatment in AF patients who underwent percutaneous coronary intervention (PCI) with stenting for ACS. Methods: Consecutive nonvalvular AF patients who received twice-daily dabigatran 110 mg (n = 389) or VKA (n = 510) and D...

AbstractThe number of patients with atrial fibrillation undergoing percutaneous coronary intervention (PCI) is increasing. Since these patients have a CHA2DS2-VASc score of 1 or higher, they should be treated with oral anticoagulation to prevent stroke. However, combination therapy with oral anticoagulation for prevention of embolic stroke and dual platelet inhibition for prevention of coronary thrombosis significantly increases bleeding complications. The optimal combination, intensity and duration of antithrombotic combination therapy is still not known. In the rather small randomized WOEST trial, the combination of a vi...
