Comparison of primary and secondary stroke prevention in patients with nonvalvular atrial fibrillation: Results from the RAFFINE registry
Atrial fibrillation (AF) is a predictor of severe stroke and early death in acute ischemic stroke patients.1 The prevalence of AF has increased as the Japanese population has aged.2 AF has been more common among patients with ischemic stroke than previously reported.3 In particular, AF patients with a history of stroke or TIA have had higher risks for stroke, hemorrhagic events, and death compared to those without.4,5 In these previous studies, most patients received warfarin for anticoagulation therapy.

Higher On-admission Serum Triglycerides Predict Less Severe Disability and Lower All-cause Mortality after Acute Ischemic Stroke
Conclusions: These data suggest that higher fasting TGs on-admission predict less severe disability, reduced disability progression, and all-cause mortality in patients with acute ischemic stroke.

Usefulness of N-Terminal Pro-B-Type Natriuretic Peptide Levels for Stroke Risk Prediction in Anticoagulated Patients With Atrial Fibrillation Clinical Sciences
Conclusions— In real-world cohort of anticoagulated patients with AF, NT-proBNP provided complementary prognostic information to an established clinical risk score (CHA2DS2–VASc) for the prediction of stroke/systemic embolism. NT-proBNP was also predictive of all-cause mortality, suggesting that this biomarker may potentially be used to refine clinical risk stratification in anticoagulated patients with AF.

Cross-Border Acute Ischemic Stroke Subtype Comparison Between Hispanics and Mexican Mestizos (P1.123)
CONCLUSIONS: Small artery ischemic strokes were the most common subtype in both MM and Hispanic patients, and occurred with a similar frequency in the two populations. This similarity could be a consequence of a high pre-existing condition of hypertension in both groups. A higher incidence of large vessel and cardioembolic ischemic strokes were seen in MM compared with Hispanics, which may reflect the higher number of patients with risk factors of smoking and atrial fibrillation in the MM group.Disclosure: Dr. Cerdan-Trevino has nothing to disclose.

Troponin Elevation in Intra-arterial Stroke Intervention (P4.211)
CONCLUSIONS: Aggressive treatment may increase the risk of troponin elevation without increasing mortality in AIS patients. This finding is reassuring in view of continued interest in IA treatment of stroke in addition to tPA thrombolysis.Disclosure: Dr. Kumar has nothing to disclose. Dr. Mehta has nothing to disclose.

Factors Associated with Proximal Carotid Axis Occlusion in Patients with Acute Stroke and Atrial Fibrillation
Conclusions: Female sex, advanced age, history of systemic embolism, and higher BNP level were independently associated with more proximal carotid axis occlusion. Patients with AF having these factors may be prone to have relatively large thrombi in the heart.

Impaired Renal Function in Stroke Patients with Atrial Fibrillation
In this study, we analyzed frequency and predictors for impaired renal function and its impact on functional outcome in stroke patients with underlying AF.Methods: We analyzed 272 patients with acute ischemic stroke and AF of our prospective, observational stroke database. Estimated glomerular filtration rate (eGFR) was calculated on admission and during hospitalization from the equation of the Modification Diet for Renal Disease. Outcome measures included mortality and functional outcome at 90 days, assessed as modified Rankin Scale (mRS) score.Results: On admission, impaired renal function was found in 41.5% (n = 113)...

Prevalence of Intracranial Stenosis in a Norwegian Ischemic Stroke Population
Conclusions: IS occurs in approximately 10% and is symptomatic in about 7% of a Norwegian ischemic stroke/TIA population. Diabetes mellitus appears to be the major risk factor for IS.

Atrial Fibrillation and Cognitive Decline-The Role of Subclinical Cerebral Infarcts: The Atherosclerosis Risk in Communities Study Clinical Sciences
Conclusions— The association of incident AF with cognitive decline in stroke-free individuals can be explained by the presence or development of SCIs, raising the possibility of anticoagulation as a strategy to prevent cognitive decline in AF.

Risk of Thromboembolic Events in Atrial Fibrillation With Chronic Kidney Disease Clinical Sciences
Conclusions— Impaired renal function is an independent predictor of stroke or systemic embolism in patients with nonvalvular AF. Consideration of renal function may improve stroke risk stratification in patients with AF.

Detection of Paroxysmal Atrial Fibrillation in Very Young Cryptogenic Ischemic Stroke Patients under 40 Years: A Three Week ECG-Holter Monitoring Study (P7.121)
CONCLUSIONS: PAF was detected in 5 [percnt] of very young CIS patients < 40 years. Long-term ECG-Holter monitoring seems to be beneficial in the detection of PAF also in very young stroke population.

Improved ischemic stroke outcome prediction using model estimation of outcome probability: The THRIVE‐c calculation
ConclusionBy computing the logistic equation with patient‐specific continuous variables in the THRIVE‐c calculation, outcomes at the individual patient level are more accurately estimated. Given the widespread availability of computers and devices at the point of care, such calculations can be easily performed with a simple user interface.

Very short paroxysms account for more than half of the cases of atrial fibrillation detected after stroke and TIA: a systematic review and meta‐analysis
ConclusionsThe clinical and prognostic significance of poststroke atrial fibrillation episodes shorter than 30 s is unknown. The high frequency of poststroke atrial fibrillation episodes shorter than 30 s justify further investigation into the risk of stroke recurrence and the risk–benefit profile of anticoagulation for this patient population.

The Clinical Relevance of Microbleeds in Stroke study (CROMIS‐2): rationale, design, and methods
Background and rationaleThe increasing use of oral anticoagulants, mostly to prevent ischemic stroke due to atrial fibrillation in an ageing population, has been associated with a fivefold increased incidence of oral anticoagulant‐associated intracerebral hemorrhage: a rare, serious, and unpredictable complication. We hypothesize that cerebral microbleeds and other markers of cerebral small vessel disease on magnetic resonance imaging, and genetic polymorphisms (e.g. influencing cerebral small vessel integrity or anticoagulation stability), are associated with an increased risk of oral anticoagulant‐associated intracer...
