Use of Warfarin at Discharge Among Acute Ischemic Stroke Patients With Nonvalvular Atrial Fibrillation in China Clinical Sciences
Conclusions— The rate of warfarin use remains low among patients with ischemic stroke and known nonvalvular atrial fibrillation in China. Hospital size and academic status together with patient age, heart failure, heavy alcohol drinking, international normalized ratio in hospital, and stroke severity on admission were each independently associated with the use of warfarin at discharge. There is much room for improvement for secondary stroke prevention in nonvalvular atrial fibrillation patients in China.

Predicting Major Bleeding in Ischemic Stroke Patients With Atrial Fibrillation Brief Report
Conclusions—Performance of prediction models for major bleeding in patients with cerebral ischemia and atrial fibrillation is modest but comparable with performance in patients with only atrial fibrillation. Bleeding risk scores cannot guide treatment decisions for oral anticoagulants but may still be useful to identify modifiable risk factors for bleeding. Clinical usefulness may be best for ORBIT, which is based on a limited number of easily obtainable variables and showed reasonable performance.

Ischemic Stroke and Intracranial Hemorrhage With Aspirin, Dabigatran, and Warfarin: Impact of Quality of Anticoagulation Control Clinical Sciences
Conclusions— In Chinese patients with atrial fibrillation, the benefits of warfarin therapy for stroke prevention and ICH risk are closely dependent on the quality of anticoagulation, as reflected by TTR. Even at the top TTR quartile, warfarin was associated with a higher stroke and ICH risk than dabigatran.

Risk of warfarin-associated intracerebral haemorrhage after ischaemic stroke is low and unchanged during the 2000s
Commentary on: Asberg A, Erisksson M, Henriksson KM, et al.. Warfarin-associated intracerebral hemorrhage after ischemic stroke. Stroke 2014;45:2118–20. Context Since its isolation during the early half of the 20th century from the mouldy hay responsible for ‘sweet clover disease’ in cattle, warfarin has become the most widely used oral anticoagulant.1 Indications include atrial fibrillation (AF), mechanical prosthetic valves and venous thromboembolism treatment.2 Warfarin reduces stroke risk in patients with AF by nearly two-thirds; AF accounts for 20% of ischaemic strokes, which tend to be more severe t...

Stroke risk 'higher at start of warfarin treatment'
Conclusion This study has found that warfarin was associated with an increased risk of ischaemic stroke during the first 30 days of treatment. After 30 days of treatment, warfarin was associated with a decreased risk of stroke. However, this study has a number of limitations that should be considered: All information was from patient records, which means that it wasn't subject to recall bias, but the information may not be complete – we do not know if, for example, people took the medication they were prescribed. There may be other factors (confounders) that explain the association seen. In particular, the ba...

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, ...

Stroke and bleeding risk assessment in atrial fibrillation: when, how, and why?
The objective of this review article is to provide an overview of stroke and bleeding risk assessment in AF. There would be particular emphasis on when, how, and why to use these risk stratification schemes, with a specific focus on the CHADS2 [congestive heart failure, hypertension, age, diabetes, stroke (doubled)], CHA2DS2-VASc [congestive heart failure or left ventricular dysfunction, hypertension, age ≥75 (doubled), diabetes, stroke (doubled)-vascular disease, age 65–74 and sex category (female)], and HAS-BLED [hypertension (i.e. uncontrolled blood pressure), abnormal renal/liver function, stroke, bleeding his...

Primary Prevention of Ischaemic Stroke in Atrial Fibrillation: New Oral Anticoagulant Drugs for all?
Abstract Atrial fibrillation (AF) confers a 4.5% risk of stroke per year. The risk of stroke increases with various risk factors and until recently, warfarin has been the gold standard of thromboembolism prophylaxis in AF for many years. The dosage of warfarin requires regular adjustment dependent on the INR, to keep within a narrow therapeutic range of 2.0- 3.0. The INR can be altered by concomitant drugs, foods and alcohol and requires inconvenient blood monitoring. Underanticoagulation places patients at risk of stroke, whilst over-anticoagulation confers significant bleeding risk. Consequently approximately ha...

Recurrent Ischemic Stroke: Strategies for Prevention.
Abstract Recurrent strokes make up almost 25% of the nearly 800,000 strokes that occur annually in the United States. Risk factors for ischemic stroke include hypertension, diabetes mellitus, hyperlipidemia, sleep apnea, and obesity. Lifestyle modifications, including tobacco cessation, decreased alcohol use, and increased physical activity, are also important in the management of patients with a history of stroke or transient ischemic attack. Antiplatelet therapy is recommended to reduce the risk of recurrent ischemic stroke. The selection of antiplatelet therapy should be based on timing, safety, effectiveness, ...

Real ‐World Clinical Characteristics and Treatment Patterns of Individuals Aged 80 and Older with Nonvalvular Atrial Fibrillation: Results from the ReAl‐life Multicenter Survey Evaluating Stroke Study
ConclusionNearly one‐fifth of individuals with NVAF in this real‐world sample were aged 80 and older. Participants aged 80 and older were more likely to be female and have more comorbidities than those who were younger than 80. Those aged 80 and older with AF were less likely to receive anticoagulants than those who were younger than 80, but having more comorbidities and other individual‐level characteristics may explain this difference. When they were prescribed OACs, participants aged 80 and older had poorer quality of anticoagulation than those who were younger, suggesting opportunities for improvement.

Characteristics of Intracerebral Hemorrhage During Rivaroxaban Treatment: Comparison With Those During Warfarin Brief Reports
Conclusions— Rivaroxaban-associated ICH occurs in patients at high risk for major bleeding. However, they had a relatively small hematoma, no expansion of hematoma, and favorable functional and vital outcomes compared with warfarin-associated ICH.

Risk of aspirin-related bleeding is higher in the over-75s
Conclusion This valuable cohort study helps to quantify the extent of bleeding risk in people taking aspirin for secondary prevention of cardiovascular disease. Aspirin is well known to carry bleeding risk – particularly in older adults – but this study suggests the risk may be higher than previously thought. The researchers say that for adults under the age of 75, the annual bleeding risk at around 1% is similar to that suggested by previous trials, as is the ratio of bleeds to the number of cardiovascular events. However, this risk increases for older adults, especially for major bleeds of the stomach and upper diges...

87 Evolution of Atrial Fibrillation
ConclusionThere has been a significant increase in primary prevention practices for AF and this is reflected in the number of stroke patients presenting with known AF on a NOAC, however more needs to be done as there are still patients who have AF that are not being anticoagulated in the community.
