Bootstrap-based Feature Selection to Balance Model Discrimination and Predictor Significance: A Study of Stroke Prediction in Atrial Fibrillation.
Authors: Li X, Sun Z, Du X, Liu H, Hu G, Xie G Abstract Atrial fibrillation (AF) is a common cardiac arrhythmias, which increases the risk and severity of ischemic stroke. For predicting ischemic stroke in AF patients, a risk prediction model that can achieve both good model discrimination (e.g., A UC) and statistical significance ofpredictors is required in real clinical practices. In this paper, we propose a new bootstrap-based wrapper (Boots-wrapper) method of feature selection, and apply this method on Chinese Atrial Fibrillation Registry data to develop 1-year stroke prediction models in AF. The proposed metho...

Stroke care in 1960 and now-the case of Ren é Maugras.
CONCLUSION: The entire field of acute stroke care has been revolutionized in the last 60 years. Big data management, telemedicine, software, new brain and vascular imaging techniques, biomarkers, robotics etc., are currently in development and again should lead to new and surprising changes during the next decades.

Sepsis-driven atrial fibrillation and ischaemic stroke. Is there enough evidence to recommend anticoagulation?
Eur J Intern Med. 2021 Nov 8:S0953-6205(21)00361-7. doi: 10.1016/j.ejim.2021.10.022. Online ahead of print.ABSTRACTSepsis can lead to cardiac arrhythmias, of which the most common is atrial fibrillation (AF). Sepsis is associated with up to a six-fold higher risk of developing AF, where it occurs most commonly in the first 3 days of hospital admission. In many patients, AF detected during sepsis is the first documented episode of AF, either as an unmasking of sub-clinical AF or as a newly developed arrhythmia. In the short term, sepsis that is complicated by AF leads to longer hospital stays and an increased risk of inpati...

Cardioembolic stroke related to limb-girdle muscular dystrophy 1B
Conclusion: We suggested that LMNA gene related myopathies should be considered in young stroke patients with long-standing myopathic features.

The impact of CHADS2 score on late stroke after the Cox maze procedure
Conclusions: The risk of stroke or transient ischemic attack in patients after a surgical Cox maze procedure was low and not associated with CHADS2 score or warfarin use. Given the known risks of warfarin, we recommend discontinuation of anticoagulation 3 months after the procedure if the patient has no evidence of atrial fibrillation, has discontinued antiarrhythmic medications, and is without any other indication for systemic anticoagulation.

Stroke Prevention in Atrial Fibrillation in Older Adults: Existing Knowledge Gaps and Areas for Innovation: A Summary of an American Federation for Aging Research Seminar
This article summarizes the meeting discussion and emphasizes innovative topic areas that may ultimately facilitate the application of novel preventive, diagnostic, and therapeutic insights into the management of older adults with AF. The opinions of those that participated in the meeting limit this report, which may not represent all of the questions that other experts in this field might raise.

Stroke and ventricular arrhythmias
Abstract: Electrocardiographic abnormalities and cardiac arrhythmias are commonly noted after acute stroke. Risk of malignant ventricular arrhythmias is increased after a stroke and is associated with sudden cardiac death. Autonomic imbalance modulated by direct injury to neurogenic structures and enhanced by catecholamine storm can lead to myocardial damage and arrhythmogenesis. Experimental and clinical evidence suggests that insular cortex infarcts play a key role in autonomic dysregulation that lead to arrhythmias in the acute setting. Management of ventricular arrhythmias associated with acute stroke should focus on c...

Stroke and Bleeding Risks in Patients with Atrial Fibrillation
Publication date: April 2014 Source:Interventional Cardiology Clinics, Volume 3, Issue 2 Author(s): Abhishek Maan , Jeremy N. Ruskin , E. Kevin HeistTeaser Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with a substantial risk of stroke and mortality. Strokes in patients with AF are associated with a greater disability and poorer outcomes than strokes in patients in sinus rhythm. Patients with AF are at increased risk of bleeding, especially if they use anticoagulant therapy. Recent research in the field of anticoagulation has led to development of new anticoagulants for stroke preventio...

Neuroanatomical correlates of severe cardiac arrhythmias in acute ischemic stroke
Abstract Neurocardiological interactions can cause severe cardiac arrhythmias in patients with acute ischemic stroke. The relationship between the lesion location in the brain and the occurrence of cardiac arrhythmias is still discussed controversially. The aim of the present study was to correlate the lesion location with the occurrence of cardiac arrhythmias in patients with acute ischemic stroke. Cardiac arrhythmias were systematically assessed in patients with acute ischemic stroke during the first 72 h after admission to a monitored stroke unit. Voxel-based lesion-symptom mapping (VLSM) was used to correlate...

Direct Oral Anticoagulants for the Prevention of Stroke in Patients with Nonvalvular Atrial Fibrillation: Understanding Differences and Similarities
Abstract The presence of atrial fibrillation (AF), the most common sustained cardiac arrhythmia, significantly increases the risk for stroke. Current guidelines recommend that the vitamin K antagonist warfarin or direct oral anticoagulants (DOACs), such as the approved direct thrombin inhibitor dabigatran and the approved direct factor Xa inhibitors apixaban, rivaroxaban, and edoxaban, should be used for thromboprophylaxis in patients with nonvalvular AF at risk for stroke or systemic embolic events (SEE). Warfarin, the mainstay of stroke prevention in AF, increases the risk of major bleeding. Furthermore, warfari...
