Atrial Fibrillation had Less Impact on the Risk of Ischemic Stroke in Non-anticoagulated Patients Undergoing Hemodialysis: Insight from the RAKUEN study.
Conclusion A great impact on death, but not ischemic stroke, was observed in non-anticoagulated hemodialysis patients with AF in comparison to those without AF from the analysis of the RAKUEN study. PMID: 29607945 [PubMed - as supplied by publisher]

Cerebral microbleeds and intracranial haemorrhage risk in patients anticoagulated for atrial fibrillation after acute ischaemic stroke or transient ischaemic attack (CROMIS-2): a multicentre observational cohort study
This study is registered with ClinicalTrials.gov, number NCT02513316. Findings Between Aug 4, 2011, and July 31, 2015, we recruited 1490 participants of whom follow-up data were available for 1447 (97%), over a mean period of 850 days (SD 373; 3366 patient-years). The symptomatic intracranial haemorrhage rate in patients with cerebral microbleeds was 9·8 per 1000 patient-years (95% CI 4·0–20·3) compared with 2·6 per 1000 patient-years (95% CI 1·1–5·4) in those without cerebral microbleeds (adjusted hazard ratio 3·67, 95% CI 1·27–10·60). Compared with the HAS-BLED score alone (C-index 0·41, 95% CI 0·29–0Â...

Long-term health benefits of stroke prevention with apixaban versus vitamin K antagonist warfarin in patients with non-valvular atrial fibrillation in Germany: a population-based modelling study.
CONCLUSION: This study demonstrated that using apixaban instead of VKA for stroke prevention can lead to considerable reduction in cardiovascular events. PMID: 30295561 [PubMed - as supplied by publisher]

Novel Oral Anticoagulants for the Prevention of Stroke in Patients with Atrial Fibrillation and Hypertension: A Meta-Analysis
ConclusionsOur findings suggest that NOACs can be recommended for the prevention of stroke or systemic embolism in patients with AF and hypertension.

Number needed to treat based on real-world evidence for non-vitamin K antagonist oral anticoagulants versus vitamin K antagonist oral anticoagulants in stroke prevention in patients with non-valvular atrial fibrillation.
CONCLUSIONS: The NNT calculation, when approached and interpreted properly, is a practical measure of the effectiveness of a treatment. The calculation based on HRs showed that NOACs are safe and effective alternatives to VKAs in real life. PMID: 30969801 [PubMed - as supplied by publisher]

Patient characteristics and stroke and bleeding events in nonvalvular atrial fibrillation patients treated with apixaban and vitamin K antagonists: a Spanish real-world study.
Conclusion: Patients prescribed apixaban for the treatment of nonvalvular atrial fibrillation had lower rates of thromboembolic events and minor/major bleeding than patients on acenocoumarol. PMID: 31333045 [PubMed - as supplied by publisher]

Management of oral anticoagulation in very old patients with non valvular atrial fibrillation related acute ischemic stroke
AbstractThe optimal management of oral anticoagulation (OAC) in the acute phase of non valvular atrial fibrillation (NVAF)-related acute ischemic stroke (AIS) remains controversial, especially in very old patients. Therefore, the aim of our study was to evaluate the practical management of OAC in this context. We conducted an observational retrospective study on patients 85-years old and older admitted to two Italian hospitals for NVAF-related AIS. For each patient, clinical and brain computed tomography data were recorded. Type of OAC (vitamin K antagonists, VKAs or Direct Oral Anticoagulants, DOACs), dosage and starting ...

Abbott Wins Approval for CATALYST Trial for At-Risk Stroke Patients
This study is an extremely important step in assessing the Amplatzer Amulet as an effective non-prescription drug alternative for patients with AFib who are at an increased risk for ischemic stroke." In an email sent to MD+DI, Abbott wrote, “We already have an Amulet IDE trial underway that is intended to support our submission for approval in the U.S. for Amplatzer Amulet. The newly announced CATALYST trial will support our submission for an expanded indication for Amulet as a safe and effective alternative to NOAC drugs for patients with atrial fibrillation and at risk of stroke.” Abbo...

Non-Vitamin K Antagonist Oral Anticoagulants in Secondary Stroke Prevention in Atrial Fibrillation Patients: An Updated Analysis by Adding Observational Studies
ConclusionBased on current data, the use of NOACs is at least non-inferior to the use of VKAs in AF patients for secondary stroke prevention irrespective of NOAC type.

Anticoagulants for Stroke Prevention in Atrial Fibrillation in Elderly Patients
AbstractIschaemic stroke and systemic embolism are the major potentially preventable complications of atrial fibrillation (AF) leading to severe morbidity and mortality. Anticoagulation using vitamin K antagonists (VKA) or non-vitamin K oral anticoagulants (NOACs) is mandatory for stroke prevention in AF. Following approval of the four NOACs dabigatran, rivaroxaban, apixaban, and edoxaban, the use of VKA is declining steadily. Increasing age with thresholds of 65 and 75  years is a strong risk factor when determining annual stroke risk in AF patients. Current recommendations such as the “2016 Guidelines for the manageme...

Incidence and consequences of resuming oral anticoagulant therapy following hematuria and risks of ischemic stroke and major bleeding in patients with atrial fibrillation
In conclusion, more and more patients who suffer a hematuria while on oral anticoagulant therapy resume NOAC. Patients resuming NOAC have similar risks of ischemic stroke/systemic embolism and major bleeding compared with those resuming VKA.

Rivaroxaban in Recurrent Ischemic Stroke Due to Protein S Deficiency: A Case Report
In this study our patient was treated with rivaroxaban. Protein S deficiency may be a predisposing factor in recurrent ischemic stroke, and rivaroxaban can be a safe and effective treatment option. Further studies are needed to confirm our findings.

Characteristics of Ischemic Versus Hemorrhagic Stroke in Patients Receiving Oral Anticoagulants: Results of the PASTA Study
Conclusion The presence of CMBs, a history of stroke, natriuretic peptide and D-dimer levels, and PT-INR may be useful for risk stratification of either IS/TIA or ICH development in patients with AF receiving OACs.PMID:34483213 | DOI:10.2169/internalmedicine.8113-21
