Quest for the Perfect Anticoagulant
The current referenced meta-analysis study by Selvaraj et al1 examines the relative merits of anticoagulation with a direct oral anticoagulant (DOAC) versus vitamin K antagonist (VKA) after transcatheter aortic valve implantation (TAVI) in patients meeting the indications for anticoagulation because of atrial fibrillation (AF). Although guidelines vary, the general consensus appears to indicate noninferiority to superiority of DOACs in the treatment of nonvalvular AF. In the landmark Apixiban for Reduction In Stroke and Other Thromboemoblic Events in Atrial Fibrillation trial comparing apixaban to warfarin in patients with...

High rates of oral anticoagulation in atrial fibrillation patients observed in a large multi-specialty health system in the Northeast
ConclusionsWe show dramatically increased OAC usage among patients with AF and that NOACs comprise the large majority of OACs compared with previous studies. This suggests an association between widespread adoption of NOACs and increased oral anticoagulation rates. Future directions include assessing barriers to oral anticoagulation and developing interventions to reduce disparity in OAC use between clinics.

Warfarin faring better: Vitamin K antagonists beat rivaroxaban and apixaban in the INVICTUS and PROACT Xa trials
J Thromb Haemost. 2023 Jul 8:S1538-7836(23)00523-8. doi: 10.1016/j.jtha.2023.06.036. Online ahead of print.ABSTRACTAlthough guidelines give preference to the direct oral anticoagulants (DOACs) over vitamin K antagonists (VKAs) for stroke prevention in most patients with atrial fibrillation (AF), DOACs are not recommended in those with rheumatic heart disease or mechanical heart valves. The results of the INVICTUS trial (Investigation of Rheumatic AF Treatment Using Vitamin K Antagonists, Rivaroxaban or Aspirin Studies), which compared rivaroxaban with a VKA in patients with rheumatic heart disease associated AF, and the PR...

Effect of prior anticoagulation therapy on stroke severity and in-hospital outcomes in patients with acute ischemic stroke and atrial fibrillation
We aimed to assess the prevalence of prior anticoagulation therapy (warfarin or non-vitamin K antagonist oral anticoagulants [NOACs]) among patients with acute ischemic stroke (AIS) and atrial fibrillation (AF) in China and investigate the associations between prior anticoagulation therapy and initial stroke severity and in-hospital outcomes.

Direct Oral Anticoagulants Versus Warfarin Across the Spectrum of Kidney Function: Patient-Level Network Meta-Analyses From COMBINE AF
CONCLUSIONS: Standard-dose DOACs are safer and more effective than warfarin down to a CrCl of at least 25 mL/min. Lower-dose DOACs do not significantly lower the incidence of bleeding or ICH compared with standard-dose DOACs but are associated with a higher incidence of S/SE and death. These findings support the use of standard-dose DOACs over warfarin in patients with kidney dysfunction.PMID:37042255 | DOI:10.1161/CIRCULATIONAHA.122.062752

Direct Oral Anticoagulants as the First Choice of Anticoagulation for Patients with Peripheral Artery Disease to Prevent Adverse Vascular Events: A Systematic Review and Meta-Analysis
J Cardiovasc Dev Dis. 2023 Feb 3;10(2):65. doi: 10.3390/jcdd10020065.ABSTRACTThe best method of anticoagulation for patients with peripheral artery disease (PAD) is still a topic of interest for physicians. We conducted a meta-analysis to compare the effects of direct oral anticoagulants (DOACs) with those of vitamin-K-antagonist (VKA) anticoagulants in patients with peripheral artery disease. Five databases (Medline (via PubMed), EMBASE, Scopus, Web of Science, and CENTRAL) were searched systematically for studies comparing the effects of the two types of anticoagulants in patients with PAD, with an emphasis on lower-limb...

Integrating Real-World Evidence in Economic Evaluation of Oral Anticoagulants for Stroke Prevention in Non-valvular Atrial Fibrillation in a Developing Country
ConclusionsIn a developing country where suboptimal anticoagulation control is common, apixaban was the cost-effective alternative to warfarin for patients with both low and intermediate TTR control.

Antiplatelet Agents and Oral Anticoagulant Use in Patients with Atrial Fibrillation and Carotid Artery Disease After First-Time Ischaemic Stroke
CONCLUSIONS: The results suggest for patients with AF and carotid artery disease after ischaemic stroke, receiving NOACs without APA is associated with a lower risk of major bleeding with no negative impact on recurrent stroke or mortality. Evidence from randomised trials is needed to confirm this finding.PMID:36692658 | DOI:10.1007/s10557-023-07433-4

Can Warfarin be replaced by non-vitamin K anticoagulants in prosthetic valves?
In this report, the authors discussed the published data related to NOACs use in prosthetic valves highlighting the proposed mechanisms of NOACs failure and other controversial data regarding their efficacy and safety in prosthetic valves.EXPERT OPINION: Although NOACs have proven to be even safer and more effective alternatives to vitamin K antagonists (VKAs) in several indications for anticoagulation, the data regarding their safety and efficacy in prosthetic heart valves is still debatable. The controversial data regarding NOACs use in prosthetic valves renders it difficult to define specific guideline-recommendation fo...

Oral Anticoagulant Use in Patients With Atrial Fibrillation and Chronic Kidney Disease: A Review of the Evidence With Recommendations for Australian Clinical Practice
Chronic kidney disease is common in patients with atrial fibrillation (AF) and is associated with heightened risks of stroke/systemic embolisation and bleeding. In this review we outline the evidence for AF stroke prevention in kidney disease, identify current knowledge gaps, and give recommendations for anticoagulation at various stages of chronic kidney disease.Overall, anticoagulation is underused. Warfarin use becomes increasingly difficult with advancing kidney disease, with difficulty maintaining international normalised ratio (INR) in therapeutic range, increased risk of intracranial and fatal bleeding compared to n...

Comparison of Dabigatran Versus Warfarin Treatment for the Prevention of New Cerebral Lesions in Valvular Atrial Fibrillation
Atrial fibrillation is one of the most common arrhythmias in the United States and is associated with an increased risk of thromboembolic events.1 The American Heart Association/American College of Cardiology/Heart Rhythm Society guidelines recommend oral anticoagulation with either warfarin or oral non-vitamin K antagonists for patients diagnosed with atrial fibrillation with a high risk for ischemic stroke based on the CHA2DS2-VASc score.2 The recently published article “Comparison of Dabigatran Versus Warfarin Treatment for Prevention of New Cerebral Lesions in Valvular Atrial Fibrillation” discussed the efficacy of...

Persisting stroke risk in patients with atrial fibrillation despite proper anticoagulation – Unmet clinical needs
Oral anticoagulation (OAC) is crucial to prevent cardioembolic stroke in patients with atrial fibrillation (AF). Development of the direct oral anticoagulants (DOAC), which inhibit activities of the coagulant proteases thrombin and activated factor X (FXs), has improved the safety and efficacy of anticoagulation in AF, compared to traditional vitamin K antagonists like warfarin [1,2]. Yet in a small, but numerically relevant proportion of up to 2% of patients, this cornerstone principle fails for unclear reasons.
