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]

Effectiveness and Safety of Four Direct Oral Anticoagulants in Asians with Non-valvular Atrial Fibrillation.
CONCLUSIONS: In the largest real-world practice study among Asians with NVAF, four DOACs were associated with lower risks of thromboembolism and bleeding than warfarin. There was consistency even amongst high risk subgroups and whether standard dose or low dose regimes were compared. PMID: 31103697 [PubMed - as supplied by publisher]

Reversal of Direct Oral Anticoagulants: Current Status and Future Directions
Semin Respir Crit Care Med 2017; 38: 040-050 DOI: 10.1055/s-0036-1597831Direct oral anticoagulants (DOACs) are increasingly used for prevention and treatment of venous thromboembolism and for prevention of stroke in patients with nonvalvular atrial fibrillation. In phase III clinical trials that included more than 100,000 patients, the DOACs were at least as effective as vitamin K antagonists (VKAs) and were associated with less serious bleeding, particularly less intracranial bleeding. Real-world evidence supports these outcomes. Despite this, some physicians and patients are concerned about serious bleeding or emergencie...
