Single-Center Description of Therapeutic Anticoagulation Practices and Outcomes in Large Hemispheric Infarctions
Discussion Although radiographic HT is common among patients with LHI, it does not always portend symptomatic clinical deterioration. Further research regarding AC timing and safety is necessary.

Racial and Ethnic Disparities in Stroke Prevention for Atrial Fibrillation
Atrial fibrillation (AF) is the most common cardiac arrhythmia, affecting around 2% of the population (1,2) and increasing the risk of stroke by 4 to 5 times (3). Anticoagulation with Vitamin K antagonists (VKAs) such as Warfarin (4) or the newer Direct Oral Anticoagulants (DOACs) (4,5) reduces this risk by up to 60%. AF-related strokes also tend to be more severe and disabling (6).

Clinical impact of oral anticoagulation among octogenarians with atrial fibrillation and anaemia
AbstractOur study aimed to describe the efficacy and safety of oral anticoagulation (OAC) use in elderly patients (>  or = 80 years-old) with atrial fibrillation (AF) and concomitant anaemia. Data for this study were sourced from AF Research Database (NCT03760874). AF patients aged ≥ 80 who received OAC treatment, both direct oral anticoagulant (DOAC) and vitamin K antagonist (VKA) were selected. Partici pants were categorized as anaemic and non-anaemic. The primary outcome was the occurrence of overall bleeding. The primary effectiveness outcome was the occurrence of thromboembolic events (a composite of isch...

Delaying clinical events among patients with non-valvular atrial fibrillation treated with oral anticoagulants: Insights from the ARISTOPHANES study
CONCLUSIONS: Over 12 months after initiation, apixaban and dabigatran conferred progressive increases in event free time for stroke/SE and MB vs warfarin, whereas rivaroxaban conferred an increase in stroke/SE-free time but a loss in MB-free time vs warfarin.PMID:36456387 | DOI:10.1016/j.ejim.2022.10.021

EPH8 Factors Associated With Oral Anticoagulant Switching in Patients With Atrial Fibrillation
The objective of this study was to determine factors associated with OAC switching for VKA to DOAC, DOAC to VKA, and DOAC to DOAC switches.

Continued non-vitamin K antagonist oral anticoagulants versus vitamin K antagonists during transcatheter aortic valve implantation
CONCLUSIONS: Continued NOAC compared with continued VKA during TAVI led to comparable outcomes with regard to the composite outcome measure indicating that continued OAC with both drugs is feasible. These hypothesis-generating results need to be confirmed by a dedicated randomised controlled trial.PMID:36440479 | DOI:10.4244/EIJ-D-22-00521

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...

Left atrial appendage closure for stroke prevention in nonvalvular atrial fibrillation: A current overview
J Cardiol. 2022 Nov 15:S0914-5087(22)00277-5. doi: 10.1016/j.jjcc.2022.11.006. Online ahead of print.ABSTRACTAtrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice and its prevalence increases with age. AF causes palpitations, heart failure, and cardiogenic embolism. Of them, the most critical and fatal complication is a cardio-embolic event. Oral anticoagulation plays a central role in reducing stroke risk in AF patients. Recently, when oral anticoagulation is considered in patients with non-valvular AF who are eligible for direct oral coagulations, they are preferred to vitamin K antagoni...
