Background: Managing antithrombotic therapy transitions at hospital admission and discharge in patients with atrial fibrillation (AF) and an acute coronary syndrome (ACS) or percutaneous coronary intervention (PCI) is challenging and is affected by prior treatment. We examined oral anticoagulant (OAC) use prior to enrollment and the relationship with outcomes in the AUGUSTUS trial. Methods: Patients in AUGUSTUS (N=4,614) were analyzed according to whether they were [n=2262] or were not [n=2352] on a prior OAC. Bleeding and clinical outcomes were compared by Kaplan-Meier (KM) estimates at 180 days. For each outcome, KM estimates and treatment interactions were determined by randomized arm and prior OAC status. Results: Those with prior OAC use had higher CHA 2 DS 2 -VASC and HAS-BLED scores and more comorbid medical conditions (hypertension, heart failure, diabetes, prior stroke), and were more likely to have been enrolled following elective PCI. Prior OAC use included vitamin K antagonists (VKAs) 47%, rivaroxaban 22%, apixaban 22%, dabigatran 12%, and edoxaban 1%. There was no difference in combined ISTH major/clinically relevant non-major (CRNM) bleeding with or without prior OAC use (13.5% vs. 13.5%; HR 1.00, 95% CI 0.85-1.18). Patients with prior OAC use had lower risk of death or ischemic events (5.4% vs. 7.6%; HR 0.72, 95% CI 0.57-0.91). No interactions were observed between randomized treatment (apixaban vs. VKA and aspirin vs. placebo) and prior OAC status for outcomes other than MI where apixaban (vs. VKA) was associated with a lower risk of MI in those with prior OAC use (Figure). Conclusion: In AUGUSTUS, OAC prior to enrollment was more common in patients with comorbidities and those enrolled following elective PCI. Prior OAC was associated with fewer ischemic events but not more bleeding. Our results support the use of apixaban plus a P2Y12 inhibitor without aspirin for patients with AF and ACS/PCI, irrespective of prior OAC use.

ObjectiveTo examine the real-world patterns of oral anticoagulant (OAC) therapy in patients with acute coronary syndrome (ACS) and atrial fibrillation (AF) in Southern China undergoing percutaneous coronary intervention (PCI) and determine the clinical characteristics associated with OAC prescription.DesignA retrospective cohort study.SettingThis study was conducted in the Shunde Hospital, Southern Medical University and the second hospital of Zhaoqing, China, from January 2013 to 31 December 2018.ParticipantsPatients were aged ≥18 years, hospitalised for ACS and received PCI treatment.Outcome measuresAF was diagnosed based on an ECG recording or a Holter monitor. Prescription of OACs and antiplatelets were determined from the discharge medication list.ResultsA total of 3612 patients with ACS were included: 286 (7.9%) were diagnosed with AF, including 45 (1.2%) with paroxysmal AF, 227 (6.3%) with persistent/permanent AF and 14 (0.4%) with unclassified AF. Although 95.5% of patients with AF were at high risk (CHA2DS2-VASc score ≥2) of stroke, only 21.7% of them were discharged on OACs (10.5% received warfarin and 11.2% received non-vitamin K antagonist OACs). Patients with pre-admission use of OAC, a HAS-BLED score <3, with persistent/permanent AF were more likely to receive OAC treatment at discharge.ConclusionWe found that approximately 8% of patients who underwent PCI during ACS hospitalisation also demonstrated AF. Anticoagulant therapy was greatly underused. Patients with paroxysmal AF and an increased risk of bleeding were less likely to receive anticoagulant treatment. Further efforts should be made to increase the adherence to guideline recommendations for OACs.

Abstract Background Antithrombotic therapy is effective in preventing ischemic and thromboembolic events, however it simultaneously increases the risk of bleeding. The efforts thus focus on balancing the intensity of combined antiplatelet and anticoagulant therapy. Purpose The study aimed to compare efficacy and safety of single (aspirin/clopidogrel) or dual (aspirin plus clopidogrel) antiplatelet therapy in combination with an oral anticoagulant in non-selected patient population with atrial fibrillation (AFib) and an acute coronary syndrome (ACS). Methods The analysis used data from National Registry of Reimbursed Health Services (NRRHS), which contains data of the entirety of health care paid from the public health insurance (almost 100% of healthcare in the Czech Republic) combined with the database of death records. Occurrence of an ACS, stroke, and bleeding requiring hospitalization within one year was compared in patients discharged on dual and triple antithrombotic therapy. Dual antithrombotic therapy consists of aspirin/clopidogrel plus an oral anticoagulant. Triple antithrombotic therapy was defined as combination of aspirin, clopidogrel and an oral anticoagulant. Results Over a four-year period (2012–2016) 104 000 patients with an ACS were hospitalized in the Czech Republic. AFib (any types) was reported in 12.4% (N=12 891) of them (21.2% in patients 75+ years old). +AFib (vs. −AFib) patients were a higher risk population with respect to the comorbidity (diabetes, hypertension, renal disease, stroke, heart failure) (p<0.05 for all comorbidities). Oral anticoagulant therapy was indicated in 25.3% of them. PCI was performed in 57.7% (−AFib) and 43.4% (+AFib) patients, respectively. Hospital mortality was significantly higher in +AFib patients (8.6% and 5.6%, OR (95% CI): 1.585 (1.481; 1.696), p<0.001). We identified 1017 patients discharged on dual and 967 patients on triple antithrombotic therapy. Risk of recurrent ACS within one year with dual therapy was comparable to that with triple therapy (OR (95% CI): 1.219 (0.766; 1.940), p=0.403). The same was also observed for the risk of stroke (1.273 (0.648; 2.501), p=0.483). After six months, persistence on dual antithrombotic therapy (33.4% patients) was higher than on triple therapy (10.3%, p<0.001). Within the first three months, de-escalation from triple antithrombotic therapy to dual antithrombotic therapy (in 212 patients) was accompanied by a significant increase of bleeding requiring hospitalization (0% on dual vs. 3.3% on triple therapy, p=0.048). Conclusion Protective effect of dual antithrombotic therapy on the occurence of recurrent major adverse cardiovascular event is comparable to that of the triple antithrombotic therapy in non-selected patients with an acute coronary syndrome and atrial fibrillation. Moreover, long-term persistence on triple therapy is significantly lower due to bleeding risk.
