Association between Paroxysmal Atrial Fibrillation and the Left Atrial Appendage Ejection Fraction during Sinus Rhythm in the Acute Stage of Stroke: A Transesophageal Echocardiographic Study
This study aimed to investigate whether left atrial appendage (LAA) dysfunction evaluated by transesophageal echocardiography (TEE) during sinus rhythm is predictable of paroxysmal atrial fibrillation (PAF) as an embolic source in the acute stage of stroke.Methods and Results: We measured and analyzed LAA flow velocity (LAA-FV) and LAA ejection fraction (LAA-EF) in 300 acute ischemic stroke patients by TEE. We divided the acute ischemic stroke patients into 3 groups. The atrial fibrillation (AF) group (n = 58) comprised patients whose TEE was performed during AF rhythm. The PAF group (n = 42) comprised patients with a hist...

Cryptogenic Stroke with More Than One Cause versus No Cause by TOAST Classification Lacks Adequate Predictive Power for Stroke Risk Factors and Outcomes (P1.116)
Conclusion: Differentiating between cryptogenic more than one cause and cryptogenic no cause demonstrates significant difference in the rates of cardiac-related, vasculature-related, and outcome variables. However, cryptogenic more than one cause does not have significant predictive power in demographic, baseline, or outcome prediction models.Disclosure: Dr. Scullen has nothing to disclose.

90 Day Outcomes in Stroke/Transient Ischemic Attack Patients Receiving Initial or Follow-up Care in a Comprehensive Outpatient Stroke Center (P3.120)
CONCLUSIONS: The completion of diagnostic evaluation and implementation or adjustment of treatments including optimizing antiplatelet therapy or changing to coumadin when cardiac monitoring demonstrates atrial fibrillation in a timely manner has resulted in better than expected outcomes. We feel this is due to "closing the loop" in the episode of care.Disclosure: Dr. Bates has nothing to disclose. Dr. Westphal has nothing to disclose. Dr. Rainka has nothing to disclose.

The Impact of a Stroke Prevention Clinic after Discharge for TIA/ Stroke: University Hospitals Case Medical Center Comprehensive Stroke Center Experience (P3.121)
Conclusions: The burden of risk factors in our patients was very high. Although patients reported uniform adherence to treatment, risk factor control to target was good for hypertension and atrial fibrillation and poor for smoking, diabetes and dyslipidemia. Despite high rates of insurance and established primary care, multiple interventions were performed during this visit, particularly in the more disabled. The post-discharge SPC visit augments primary care and offers an important opportunity to review and revise the care plan, assess patient adherence and control of risk factors to target.*Chart and Graph imaging to be ...

Diagnostic Yield of Prolonged Cardiac Rhythm Monitoring in Cryptogenic Stroke (I2-1.003)
CONCLUSIONS: Our study demonstrates the diagnostic yield of cardiac rhythm monitoring of up to 30 days is significantly lower than previously reported. This may be secondary to differences in monitoring devices used, the variability in definition of cryptogenic stroke, and duration of monitoring. Alternatively, longer duration of monitoring with implantable devices may be needed to detect paroxysmal AF, particularly in those with clinical, electrocardiographic or echocardiographic features associated with this dysrhythmia.Disclosure: Dr. Kalani has nothing to disclose.

Mobile Cardiac Outpatient Telemetry Identifies Occult Atrial Fibrillation After Cryptogenic Stroke (I2-2.002)
CONCLUSIONS:Atrial fibrillation is detected on MCOT in a substantial minority of cryptogenic stroke patients. Age蠅60 and the presence of prior cortical or cerebellar strokes should raise suspicion for occult AF. These data may aid in the selection of patients for prolonged arrhythmia monitoring.Disclosure: Dr. Ingala has nothing to disclose. Dr. Jara has nothing to disclose.

Prescription frequency and predictors for the use of novel direct oral anticoagulants for secondary stroke prevention in the first year after their marketing in Europe – a multicentric evaluation
ConclusionsShortly after their marketing, DOAC are used as frequently as VKA for secondary stroke prevention in patients with atrial fibrillation. The decision between VKA and DOAC is mainly determined by the patient's renal function and the absence or presence of prior oral anticoagulant therapy.

Atrial Fibrillation and Paroxysmal Atrial Fibrillation Detection in Patients with Acute Ischemic Stroke
Conclusions: AF/PAF was one of the common causes of ischemic stroke in Thai patients. Most PAF was detected by continuous ECG monitoring. Snapshot 12-lead ECG and continuous ECG monitoring should be recommended in all patients with acute ischemic stroke.

Abstract 12: Accuracy and Validation of an Automated Electronic Medical Record Algorithm to Identify Patients with Atrial Fibrillation at Risk for Stroke Session Title: Concurrent I Session B: Oral Abstracts on Stroke Topics
Discussion: Automated methods can be used to identify patients with prevalent AF indicated for anticoagulation, but may suffer from misclassification of up to 12%. Misclassification is minimized by requiring a diagnosis of AF within the prior year and using a CHA2DS2-Vasc based algorithm. Despite differences in accuracy between definitions, system-wide anticoagulation rates assessed using these definitions were similar. The diagnosis codes validated in this study can be applied for internal quality improvement and observational studies, and might be adapted for use in nationwide quality reporting programs.

Prolonged cardiac monitoring after cryptogenic stroke superior to 24 h ECG in detection of occult paroxysmal atrial fibrillation
Commentary on: Gladstone DJ, Spring M, Dorian P, et al.. Atrial fibrillation in patients with cryptogenic stroke. N Eng J Med 2014;370:2467–77. Context Stroke remains a prevalent and devastating condition for many people across the world, it is a leading cause of disability and is associated with significant monetary and social losses, yet is considered to be a largely preventable disease. One-third of all strokes are considered cryptogenic after initial diagnostic evaluations. Cryptogenic stroke has been identified, only recently, as an important area of additional investigation. Part of the EMBRACE trial, Gladstone...

Embolic Stroke of Undetermined Source (ESUS): A single center study from Argentina (P1.060)
CONCLUSIONS: Even with complete work-up, upon initial assessment more than one third of ischemic stroke patients met criteria for ESUS. After one year follow-up, it is possible to reclassify some of them, mostly as cardioembolic. More studies are needed to establish unidentified etiologies and the effect of longer follow-ups.

Are there Different Rates of Acute Stroke Risk Factors in the South Texas Mexican American population? (P7.146)
CONCLUSION: In the South Texas Mexican American AIS population, there is greater then a three-fold higher prevalence of hypertension, diabetes and CHF compared with Hispanics/Latinos in the US. AFIB and CHF are significant predictors of poor outcome in this unique population.Disclosure: Dr. Tekle has nothing to disclose. Dr. Hassan has nothing to disclose. Dr. Malik has nothing to disclose.

Antiphospholipid Syndrome of Late Onset: A Difficult Diagnosis of a Recurrent Embolic Stroke
A 77-year-old woman with atrial fibrillation (AF) treated with warfarin had a cortical left middle cerebral artery (MCA) stroke (October 2009, international normalized ratio [INR], 1.6) and a cortical left frontal stroke (October 2011, INR, 1.9). Anticoagulation was adjusted. In October 2011, she had a right frontal stroke (INR, 2.3). Acetylsalicylic acid (ASA) was temporally added to the treatment. In June 2013, she had a left occipital stroke (INR, 2.3). Warfarin was changed to rivaroxaban. In August 2013, she had a right occipital stroke.

Stroke Risk Perception in Atrial Fibrillation Patients is not Associated with Clinical Stroke Risk
Clinical risk stratification models, such as the CHA2DS2-VASc, are used to assess stroke risk in atrial fibrillation (AF) patients. No study has yet investigated whether and to which extent these patients have a realistic perception of their personal stroke risk. The purpose of this study was to investigate and describe the association between AF patients' stroke risk perception and clinical stroke risk.
