Question 1 Jurgen is newly diagnosed with NVAF and has a CHA 2 DS 2 -VASc score of 4 and a HAS-BLED score of 3. According to the 2012 ESC guidelines, a NOAC should be considered rather than adjusted-dose VKA (INR 2–3) 1 Jurgen has hypertension and prior coronary artery disease Would ELIQUIS® (apixaban) be a good option for Jürgen’s stroke prevention? 1. Yes 2. No NOAC(s), novel oral anticoagulant(s); VKA, vitamin K antagonist 1. Camm et al. Eur Heart J 2012;33:2719–47.

Jürgen has a high risk of stroke as well as a high risk of bleeding and may benefit most from a therapy that protects against stroke and limits major bleeding In ARISTOTLE, ELIQUIS® (apixaban) significantly reduced the rates of stroke/SE and major bleeding as compared to warfarin 1 – In addition all-cause mortality was reduced significantly for ELIQUIS® (apixaban) vs warfarin 1 What about ELIQUIS® (apixban) 1.

Prevalence in the REACH Registry 1 Jürgen is put on ELIQUIS® (apixaban) 5 mg twice-daily How does his CAD influence his treatment? 1. Goto et al. Am Heart J 2008;156:855–63. 37,724 stable outpatients with CAD The REACH study was a large-scale international, prospective cohort study of 68,236 stable outpatients with established atherothrombosis or >= 3 atherothrombotic risk factors. Adapted from Goto et al. Am Heart J 2008;156:855–63 Atrial Fibrillation and CAD frequently coincide

CAD patients with AF have a higher rate of major clinical events than CAD patients without AF 1 p<0.0001 CV, cardiovascular 1. Goto et al. Am Heart J 2008;156:855–63. Adapted from Goto et al. Am Heart J 2008;156:855–63 37,724 patients with CAD: 12.5% prevalence of atrial fibrillation 1

What data for ELIQUIS® (apixaban) in for stroke prevention in NVAF exist in patients with prior CAD? 1 Of the study population in ARISTOTLE, 6,639 (36.5%) of patients had prior CAD Patients with prior CAD were more often male and were more likely to have prior stroke, diabetes and hypertension as compared with patients without prior CAD Patients with prior CAD were more likely to be on aspirin at baseline (42.2% vs 24.5%; p<0.001) when compared with patients without prior CAD 1.

Conclusion of the subanalysis of patients with prior CAD in ARISTOTLE In patients with NVAF, ELIQUIS® (apixaban) prevents stroke or systemic embolism and causes less major bleeding and death compared with warfarin These treatment effects were consistent in patients with and without a history of CAD As the combination of NVAF and CAD commonly occurs and as there are higher rates of CV events and death in these patients, ELIQUIS® (apixaban) may be a better option than warfarin in this high-risk group 1.

Question 2 Jürgen is now on ELIQUIS® (apixaban) for stroke prevention in NVAF and is also still taking aspirin given his prior CAD. His CAD has been stable ever since he has had the MI 2 years ago Can Jürgen discontinue taking ASA? 1. Yes, ASA can be discontinued 2. No, he still needs ASA
13
ELIQUIS® (apixaban) and antiplatelet therapy in NVAF patients In ARISTOTLE, concomitant use of ASA increased the major bleeding risk: 1 1. Apixaban SmPC. Available at http://www.ema.europa.eu There was limited (2.1%) use of concomitant dual antiplatelet therapy 1 Created from Apixaban SmPC
14
Concomitant use of ELIQUIS® (apixaban) with antiplatelet agents increases the risk of bleeding 1 Care is to be taken if patients are treated concomitantly with non-steroidal anti-inflammatory drugs (NSAIDs), including acetylsalicylic acid In patients with NVAF and conditions that warrant mono or dual antiplatelet therapy, a careful assessment of the potential benefits against the potential risks should be made before combining this therapy with apixaban 1. Apixaban SmPC. Available at http://www.ema.europa.eu
15
In ARISTOTLE, concomitant ASA use was left to the discretion of the treating physician 1 On Day 1, 4434 (24%) of patients were taking ASA 1 Event rates for apixaban vs warfarin in patients on ASA vs no ASA: Apixaban benefits vs warfarin were consistent for patients taking or not taking ASA 1 What do we know about the use of concomitant ASA in patients using apixaban? 1.

EHRA guidance on concomitant ASA 1 Stable CAD patients developing AF should receive anticoagulation, depending on their CHA 2 DS 2 -VASc score Anticoagulation without additional antiplatelet agents is considered sufficient for most AF patients with stable CAD (acute coronary syndrome ≥1 year ago; elective bare-metal stent ≥1 month; drug- eluting stent ≥6 months) The advantages of NOACs over VKA are likely to be preserved in stable CAD patients. NOACs may be an appropriate and effective alternative to VKAs 1. Heidbüchel et al. Europace 2013;15:625–51.

Patient case: Key learnings 1. Bahit et al. Int J Cardiol 2013;170:215–220; 2. Alexander et al. Eur Heart J 2014;35:224–232; 3. Heidbüchel et al. Europace 2013;15:625–651. This high-risk patient may benefit most from a therapy that protects against stroke while limiting major bleeding – In ARISTOTLE, ELIQUIS® (apixaban) significantly reduced the risk of stroke/SE and major bleeding as compared to warfarin The results of the ARISTOTLE trial were consistent in predefined subgroups according to: – Prior coronary artery disease 1 – Use of ASA 2 According to the EHRA practical guide on the use of NOACs in NVAF, anticoagulation without additional antiplatelet agents is considered sufficient for most patients with stable CAD 3
