Effectiveness and Safety of Apixaban, Dabigatran, and Rivaroxaban Versus Warfarin in Patients With Nonvalvular Atrial Fibrillation and Previous Stroke or Transient Ischemic Attack Clinical Sciences
Conclusions—Results from our study of the 3 NOACs versus warfarin in nonvalvular atrial fibrillation patients with a previous history of stroke/transient ischemic attack are relatively consistent with their respective phase III trials and previous stroke/transient ischemic attack subgroup analyses. All NOACs seemed no worse than warfarin in respect to ischemic stroke, ICH, or major bleeding risk.

Effect of Adherence to Oral Anticoagulants on Risk of Stroke and Major Bleeding Among Patients With Atrial Fibrillation Arrhythmia and Electrophysiology
Conclusions Adherence to anticoagulation is poor in practice and may be modestly improved with NOACs. Adherence to therapy appears to be most important in patients with CHA2DS2-VASc score ≥2, whereas the benefits of anticoagulation may not outweigh the harms in patients with CHA2DS2-VASc score 0 or 1.

Long-term stroke and major bleeding risk in patients with non-valvular atrial fibrillation: A comparative analysis between non-vitamin K antagonist oral anticoagulants and warfarin using a clinical data warehouse
ConclusionsIn this CDW based study, NOACs are more effective and safer than warfarin in patients with AF even with long-term follow-up. NOACs should be used to prevent ischemic stroke in patients with AF

The Use of Oral Anticoagulants for Stroke Prevention in Atrial Fibrillation Patients with History of Intra-Cranial Hemorrhage.
CONCLUSIONS: -Warfarin use may be beneficial for AF patients with prior ICH having a CHA2DS2-VASc score ≥6. Whether the use of non-vitamin K antagonist oral anticoagulants (NOACs) could lower the threshold for treatment deserves further study. PMID: 26969761 [PubMed - as supplied by publisher]

Effectiveness and Safety of Non-Vitamin K Antagonist Oral Anticoagulants in Asian Patients With Atrial Fibrillation Clinical Sciences
Conclusions—In real-world practice among a high-risk Asian atrial fibrillation population, all 3 NOACs demonstrated similar risk of ischemic stroke and lower risk of ICH compared with warfarin. All-cause mortality was significantly lower only with dabigatran and apixaban.

Oral Anticoagulation in Very Elderly Patients with Atrial Fibrillation - A Nationwide Cohort Study.
Conclusions -Among AF patients age ≥90 years, warfarin was associated with a lower risk of ischemic stroke and positive NCB. Compared to warfarin, NOACs were associated with a lower risk of ICH. Thus, OACs may still be considered as thromboprophylaxis for elderly patients with NOACs being as the more favorable choice. PMID: 29490992 [PubMed - as supplied by publisher]

Comparing the Effectiveness and Safety of Non-Vitamin K Antagonist Oral Anticoagulants and Warfarin in the Elderly Asian Patients with Atrial Fibrillation: A Nationwide Cohort Study.
CONCLUSIONS: Compared to warfarin, NOACs were associated with a significantly lower risk of adverse events, with heterogeneity in treatment effects among different age strata. Overall, the clear safety signal in favor of NOACs over warfarin was evident irrespective of age strata, being most marked in the most elderly. PMID: 31809694 [PubMed - as supplied by publisher]

Utilization of triple antithrombotic therapy in patients with atrial fibrillation undergoing percutaneous coronary intervention
ConclusionsThe utilization of TAT following PCI among high-stroke risk AF patients steadily increased from 2011 to 2020, reaching 65.4% by the end of the study period. However, in 2020, a significant proportion of 29.4% of patients still received DAPT, indicating that many AF patients undergoing PCI did not receive adequate antithrombotic therapy.

Effectiveness and Safety of Non-Vitamin K Antagonist Oral Anticoagulants in Asian Patients with Atrial Fibrillation and Valvular Heart Disease.
CONCLUSIONS: NOACs had a comparable risk of ischemic stroke and bleeding in patients with AF and VHD, and reduced the risk of venous thromboembolism, intracranial hemorrhage, and mortality, compared to warfarin. Therefore, NOAC is an effective and safe alternative to warfarin in these patients. PMID: 33538623 [PubMed - as supplied by publisher]

Thromboembolic, Bleeding, and Mortality  Risks of Rivaroxaban and Dabigatran in Asians With Nonvalvular Atrial Fibrillation
BackgroundIt is unclear whether the non –vitamin K antagonist oral anticoagulant agents rivaroxaban and dabigatran are superior to warfarin for efficacy and safety outcomes in Asians with nonvalvular atrial fibrillation (NVAF).ObjectivesThe aim of this study was to compare the risk for thromboembolic events, bleeding, and mortality associated with rivaroxaban and dabigatran versus warfarin in Asians with NVAF.MethodsA nationwide retrospective cohort study was conducted of consecutive patients with NVAF taking rivaroxaban (n  = 3,916), dabigatran (n = 5,921), or warfarin (n = 5,251) using data collected from the Taiwan...

Impact of Non-Vitamin K Antagonist Oral Anticoagulants on the Change of Antithrombotic Regimens in Patients with Atrial Fibrillation Undergoing Percutaneous Coronary Intervention
CONCLUSION: Since the introduction of NOACs, the patterns of periprocedural antithrombotic regimens have changed rapidly toward more use of TAT, specifically with NOAC-based regimen. Appropriate stroke prevention with oral anticoagulants is still underutilized in patients with AF undergoing PCI in Korea.PMID:33764010 | DOI:10.4070/kcj.2020.0407
