Recommendations on the Use of Non-Vitamin K Antagonist Oral Anticoagulants in Patients with Atrial Fibrillation (Based on 2018 European Heart Rhythm Association Practical Guide)

Non-vitamin K antagonist oral anticoagulants (NOACs) - direct oral anticoagulants - are getting the ever-broadening use in clinical practice. However, many problems related to optimal use of NOACs in specific clinical situations remain unresolved. European Heart Rhythm Association in April 2018 issued the renovated recommendations on the use of NOACs in patients with atrial fibrillation. The authors of recommendations presented some specific clinical variants for which they formulated practical advices based on the evidence obtained in randomized clinical trials. They also outlined the indications for use of NOACs, formulated practical start-program and scheme of subsequent follow-up management of patients taking NOACs. Recommendations contain information on pharmacokinetics of NOACs and their interactions with other drugs, consideration of feasibility of NOACs use in patients with chronic renal insufficiency or advanced liver disease. Many other practical problems are covered as well.

2018 KHRS Practical Guide on the Use of Non-Vitamin K Antagonist Oral Anticoagulants in Korean Patients with Atrial Fibrillation: How to Initiate and Organize the Follow-up

Non-vitamin K antagonist oral anticoagulants (NOACs) are alternatives to vitamin K antagonists to prevent stroke in patients with non-valvular atrial fibrillation (AF) and have emerged as the preferred choice. The use of NOACs is rapidly increasing in Korea after coverage by insurance since 2015. However, the rate of prescribing anticoagulants in Korean patients with AF remains low compared to other countries. Most of the NOAC anticoagulant prescriptions are issued at hospitals. As the prevalence rate of AF in Korea is expected to increase rapidly with the increase in the elderly population, the need to prescribe NOACs in primary care clinics will also increase. Therefore, The Korean Heart Rhythm Society organized the Korean Atrial Fibrillation Management Guideline Committee and analyzed all available studies based on the 2018 European Heart Rhythm Association Practical Guide on the use of NOACs for managing AF, as well as studies on Korean patients. The authors would like to introduce practical guidelines for NOAC prescriptions in Korean patients with AF. (Korean J Med 2019;94:17-39)

The 2018 European Heart Rhythm Association Practical Guide on the use of non-vitamin K antagonist oral anticoagulants in patients with atrial fibrillation: executive summary

Poniższy tekst jest streszczeniem drugiej aktualizacji oryginalnego praktycznego przewodnika opublikowanego w 2013 roku. Leki przeciwkrzepliwe niebędące antagonistami witaminy K (NOAC) stanowią cenną alternatywę dla antagonistów witaminy K (VKA) w zapobieganiu udarom u pacjentów z migotaniem przedsionków (AF) i uznano je za leki preferowane, szczególnie dla osób rozpoczynających leczenie przeciwkrzepliwe. Zarówno lekarze, jak i pacjenci przyzwyczajają się do ich stosowania w praktyce klinicznej, istnieje jednak wiele nierozwiązanych kwestii dotyczących optymalnego stosowania tych leków w określonych sytuacjach klinicznych. Europejskie Stowarzyszenie Zaburzeń Rytmu Serca (EHRA, European Heart Rhythm Association) podjęło się koordynacji opracowania jednolitego sposobu komunikowania się z lekarzami na temat stosowania różnych preparatów NOAC. Grupa określiła 20 tematów zawierających konkretne scenariusze kliniczne, w odniesieniu do których sformułowano praktyczne wskazówki na podstawie dostępnych dowodów. Do problemów klinicznych należą: 1) odpowiednia kwalifikacja pacjentów do leczenia; 2) praktyczne schematy rozpoczynania oraz monitorowania terapii za pomocą NOAC; 3) zagwarantowanie przestrzegania zaleceń przyjmowania doustnych leków przeciwkrzepliwych; 4) zmiana schematów leczenia przeciwkrzepliwego; 5) farmakokinetyka oraz interakcje lekowe; 6) stosowanie NOAC u osób z przewlekłą chorobą nerek i zaawansowaną chorobą wątroby; 7) sposoby pomiaru efektu przeciwkrzepliwego NOAC; 8) pomiar stężenia NOAC w surowicy: rzadkie wskazania, środki ostrożności, potencjalne "pułapki"; 9) postępowanie w przypadku pomyłki w dawkowaniu; 10) postępowanie w przypadku (podejrzenia) przedawkowania bez krwawienia lub badania krzepnięcia wskazujące na potencjalne ryzyko krwawienia; 11) postępowanie w przypadku krwawienia w trakcie terapii za pomocą NOAC; 12) postępowanie u pacjentów poddanych planowym zabiegom chirurgicznym, procedurom inwazyjnym czy ablacji; 13) postępowanie u pacjentów wymagających pilnej interwencji chirurgicznej; 14) pacjenci z AF oraz chorobą wieńcową; 15) unikanie pomyłek w dawkowaniu NOAC w różnych wskazaniach; 16) kardiowersja u pacjenta leczonego NOAC; 17) AF u pacjentów z ostrym udarem mózgu leczonych NOAC; 18) NOAC w sytuacjach szczególnych; 19) leczenie przeciwkrzepliwe w przypadku AF u pacjentów z nowotworami złośliwymi; 20) optymalizacja leczenia za pomocą VKA. Dodatkowe informacje oraz materiały do pobrania, jak również karty leczenia przeciwkrzepliwego w kilku językach można znaleźć na stronie internetowej EHRA (www.NOACforAF.eu).

The 2018 European Heart Rhythm Association Practical Guide on the use of non-vitamin K antagonist oral anticoagulants in patients with atrial fibrillation

The current manuscript is the second update of the original Practical Guide, published in 2013 [Heidbuchel et al. European Heart Rhythm Association Practical Guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation. Europace 2013;15:625-651; Heidbuchel et al. Updated European Heart Rhythm Association Practical Guide on the use of non-vitamin K antagonist anticoagulants in patients with non-valvular atrial fibrillation. Europace 2015;17:1467-1507]. Non-vitamin K antagonist oral anticoagulants (NOACs) are an alternative for vitamin K antagonists (VKAs) to prevent stroke in patients with atrial fibrillation (AF) and have emerged as the preferred choice, particularly in patients newly started on anticoagulation. Both physicians and patients are becoming more accustomed to the use of these drugs in clinical practice. However, many unresolved questions on how to optimally use these agents in specific clinical situations remain. The European Heart Rhythm Association (EHRA) set out to coordinate a unified way of informing physicians on the use of the different NOACs. A writing group identified 20 topics of concrete clinical scenarios for which practical answers were formulated, based on available evidence. The 20 topics are as follows i.e., (1) Eligibility for NOACs; (2) Practical start-up and follow-up scheme for patients on NOACs; (3) Ensuring adherence to prescribed oral anticoagulant intake; (4) Switching between anticoagulant regimens; (5) Pharmacokinetics and drug-drug interactions of NOACs; (6) NOACs in patients with chronic kidney or advanced liver disease; (7) How to measure the anticoagulant effect of NOACs; (8) NOAC plasma level measurement: rare indications, precautions, and potential pitfalls; (9) How to deal with dosing errors; (10) What to do if there is a (suspected) overdose without bleeding, or a clotting test is indicating a potential risk of bleeding; (11) Management of bleeding under NOAC therapy; (12) Patients undergoing a planned invasive procedure, surgery or ablation; (13) Patients requiring an urgent surgical intervention; (14) Patients with AF and coronary artery disease; (15) Avoiding confusion with NOAC dosing across indications; (16) Cardioversion in a NOAC-treated patient; (17) AF patients presenting with acute stroke while on NOACs; (18) NOACs in special situations; (19) Anticoagulation in AF patients with a malignancy; and (20) Optimizing dose adjustments of VKA.

Updated European Heart Rhythm Association practical guide on the use of non-vitamin-K antagonist anticoagulants in patients with non-valvular atrial fibrillation: Executive summary.

In 2013, the European Heart Rhythm Association (EHRA) published a Practical Guide on the use of non-VKA oral anticoagulants (NOACs) in patients with atrial fibrillation (AF) (Heidbuchel H, Verhamme P, Alings M, Antz M, Hacke W, Oldgren J, Sinnaeve P, Camm AJ, Kirchhof P, European Heart Rhythm A. European Heart Rhythm Association Practical Guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation. Europace 2013;15:625-651; Heidbuchel H, Verhamme P, Alings M, Antz M, Hacke W, Oldgren J, Sinnaeve P, Camm AJ, Kirchhof P. EHRA practical guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation: executive summary. Eur Heart J 2013;34:2094-2106). The document received widespread interest, not only from cardiologists but also from neurologists, geriatricians, and general practitioners, as became evident from the distribution of >350 000 copies of its pocket version (the EHRA Key Message Booklet) world-wide. Since 2013, numerous new studies have appeared on different aspects of NOAC therapy in AF patients. Therefore, EHRA updated the Practical Guide, including new information but also providing balanced guiding in the many areas where prospective data are still lacking. The outline of the original guide that addressed 15 clinical scenarios has been preserved, but all chapters have been rewritten. Main changes in the Update comprise a discussion on the definition of 'non-valvular AF' and eligibility for NOAC therapy, inclusion of finalized information on the recently approved edoxaban, tailored dosing information dependent on concomitant drugs, and/or clinical characteristics, an expanded chapter on neurologic scenarios (ischaemic stroke or intracranial haemorrhage under NOAC), an updated anticoagulation card and more specifics on start-up and follow-up issues. There are also many new flow charts, like on appropriate switching between anticoagulants (VKA to NOAC or vice versa), default scenarios for acute management of coronary interventions, step-down schemes for long-term combined antiplatelet-anticoagulant management in coronary heart disease, management of bleeding, and cardioversion under NOAC therapy. The Updated Guide is available in full in EP Europace (Heidbuchel H, Verhamme P, Alings M, Antz M, Diener HC, Hacke W, Oldgren J, Sinnaeve P, Camm AJ, Kirchhof P, Advisors.

The use of direct oral anticoagulants for stroke prevention in atrial fibrillation: A study on physicians' perspective and preferences

Three direct oral anticoagulants (DOACs) – Rivaroxaban, Apixaban and Dabigatran – are available for the prevention of thrombembolic events in patients with non-valvular arial fibrillation (AF) [ [1] Heidbuchel H. Verhamme P. Alings M. et al. European Heart Rhythm Association Practical Guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation. Europace. 2013; 15: 625-651 Crossref PubMed Scopus (705) Google Scholar ]. DOACs are considered as a promising alternative to vitamin K antagonists (VKAs), since frequent laboratory tests are not required and food and drug interference is reduced [ 1 Heidbuchel H. Verhamme P. Alings M. et al. European Heart Rhythm Association Practical Guide on the use of new oral anticoagulants in patients with non-valvular atrial fibrillation. Europace. 2013; 15: 625-651 Crossref PubMed Scopus (705) Google Scholar , 2 Bauer K.A. Pros and cons of new oral anticoagulants. Hematol Am Soc Hematol Educ Prog. 2013; 2013: 464-470 Crossref PubMed Scopus (166) Google Scholar ]. Improvement of patient adherence is therefore expected.

The European Heart Rhythm Association Practical Guide on the Use of New Oral Anticoagulants in Patients with Non-valvular Atrial Fibrillation - A Brief Summary.

New oral anticoagulants (NOACs) are an alternative to vitamin K antagonists (VKAs) in the prevention of stroke in patients with non-valvular atrial fibrillation (AF). The European Heart Rhythm Association (EHRA) has produced a practical guide to detail the use of NOACs in clinical practice. The guide includes a practical start-up and follow-up scheme, emphasising the importance of strict adherence to the regimen - the anticoagulant effect drops rapidly after 12-24 hours. There is also guidance on how to measure the anticoagulant effect of NOACs, switching between anticoagulant regimes and dealing with dosing errors. Physicians will have to consider the pharmacokinetic effect of drugs and co-morbidities when prescribing NOACs - plasma levels of NOACs may be affected by P-glycoprotein (P-gp) substrates, as well as cytochrome P450 (CYP3A4) inducers or inhibitors. In patients with chronic kidney disease, reduced doses of NOACs may be indicated. Guidance is also given on the management of bleeding complications, and the cessation and reinitiation of NOACs in patients undergoing surgical interventions. Finally, the use of NOACs in specific clinical situations is considered; these include patients with AF and coronary artery disease (CAD), patients presenting with acute stroke while taking NOACs and patients with cancer.
