Effect of renal function on whole blood and fibrin clot formation in atrial fibrillation patients on warfarin.
CONCLUSION: In warfarinised AF patients, renal function is linked to whole blood clot and fibrin clot formation, structure and dissolution, but has no effect on the INR. Key messages Despite oral anticoagulation, patients with atrial fibrillation (AF) still suffer from stroke and venous thromboembolism. The effect of renal function in warfarinised patients with AF is unknown and may account for excess thrombosis and/or haemorrhage. Using two different laboratory methods, our data point to an effect of renal function on clot structure and function that is independent of an effect of warfarin.

An audit of coagulation screening in patients presenting to the Emergency Department for potential stroke thrombolysis
ConclusionsA high proportion of laboratory specimens were unsuitable for testing and overall samples took an unacceptably long time to process. Point‐of‐care testing may potentially allow quicker decisions regarding whether thrombolysis is contra‐indicated but is likely to affect only a small proportion of patients.

Adoption of direct oral anticoagulants for stroke prevention in atrial fibrillation
Conclusion DOAC prescribing grew rapidly from 2013 to 2014, regionally and nationally. Warfarin prescriptions have remained stable, indicating that more patients are being appropriately anticoagulated for AF who previously were not. DOAC were found to be prescribed to patients with lower CHA2DS2VASc and HAS‐BLED scores, younger age and higher glomerular filtration rates. Aspirin therapy remains over utilised in AF.

Detecting Nonvalvular Atrial Fibrillation and Anticoagulant Therapy in Cardioembolic Ischemic Stroke.
Authors: Min J, Farooq MU Abstract Nonvalvular Atrial fibrillation (NVAF) is the most common cardiac arrhythmia associated with an increase in risk of stroke and systemic thromboembolism. Strokes related to AF are associated with higher mortality, greater disability, longer hospital stays, and lower chance of being discharged home. The present review will focus on the current status of detecting NVAF and stroke prevention when there is AF. The CHA2DS2-VASc risk stratification scheme is discussed for the identification of patients who are at risk for thromboembolic stroke related to NVAF. Patient with a CHA2DS2-VASc...

Cancer-related Stroke due to Mural Thrombus in the Extracranial Carotid Artery.
Authors: Ando D, Kobayashi J, Kuroda H, Aoki M Abstract A 41-year-old man was admitted to our hospital because of a cancer-related stroke (CRS) caused by a thrombus of the extracranial carotid artery. He had undergone neoadjuvant radiochemotherapy for metastatic colorectal adenocarcinoma. The serum D-dimer values were within the normal range. We treated him with intravenous unfractionated heparin followed by warfarin. There were no recurrent stroke events over six months. The leading cause of a CRS is an embolism caused by hypercoagulopathy, mainly represented by non-bacterial thrombotic endocarditis. However, it w...

Management of patients with atrial fibrillation and chronic kidney disease in light of the latest guidelines.
Authors: Młodawska E, Tomaszuk-Kazberuk A, Łopatowska P, Musiał WJ, Małyszko J Abstract Atrial fibrillation (AF) frequently occurs in patients with chronic kidney disease (CKD), and the rate reaches even 30% in patients with end-stage renal disease (ESRD). Patients with AF and CKD have a significantly higher risk of thrombotic complications, particularly ischemic stroke, and at the same time, a higher bleeding risk (proportionally to the grade of renal failure). In addition, AF and CKD share a number of comorbidities and risk factors, which results in increased mortality rates. Moreover, disturbances in hemosta...

New reversal agent for factor Xa inhibitors shows promise
Commentary on: Siegal DM, Curnette JT, Connolly SJ, et al.. Andexanet alfa for the reversal of Factor Xa inhibitor activity. N Engl J Med 2015;373:2413–24. Context Direct oral anticoagulants (DOACs) have emerged as alternatives to vitamin K-antagonists (eg, warfarin) for the long-term management of stroke prevention for non-valvular atrial fibrillation or venous thromboembolic disease. Favourable side-effect profiles and absence of therapeutic monitoring are important benefits of these newer agents. Warfarin is readily reversed with fresh frozen plasma (FFP) or prothrombin complex concentrates.1 The first reversal ag...

Quality of warfarin control in atrial fibrillation patients in South East Queensland, Australia
ConclusionsThe observed mean TTR of over 80% is superior to the minimum recommended threshold of 60%. The TTR achieved by the Queensland pathology practice demonstrates that dedicated warfarin programs can produce high quality warfarin care ensuring full benefit of warfarin for Australian patients.

A tailored treatment strategy: a modern approach for stroke prevention in patients with atrial fibrillation
The objective of this review is to provide an overview of modern AF stroke prevention with a focus on tailored treatment strategies. Biomarkers and genetic factors have been proposed to help identify ‘high‐risk’ patients to be targeted for oral anticoagulation, but ultimately their use must be balanced against that of more simple and practical considerations for everyday use. Current guidelines have directed focus on initial identification of ‘truly low‐risk’ patients with AF, that is those patients with a CHA2DS2‐VASc [congestive heart failure, hypertension, age ≥75 years (two points), diabetes mellitus, ...

Comparison of aspirin and Naoxintong Capsule (脑心通胶囊) with adjusted-dose warfarin in elderly patients with high-risk of non-valvular atrial fibrillation and genetic variants of vitamin K epoxide reductase
Conclusions Aspirin combined with NXT and warfarin displayed comparable rates of primary end point including ischemic stroke and all-cause death during the 1-year follow-up. However, as compared with warfarin, the combination therapy reduced the rate of serious bleeding. Therefore, aspirin combined with NXT might provide an alternative pharmacotherapy in preventing ischemic stroke for elderly patients with NAVF who cannot tolerate warfarin. (No. ChiCTR-TRC-13003596)
