Oral anticoagulant use for stroke prevention in atrial fibrillation patients with difficult scenarios

Publication date: September 2018Source: IJC Heart &Vasculature, Volume 20Author(s): Ting-Yung Chang, Jo-Nan Liao, Tze-Fan Chao, Jennifer Jeanne Vicera, Chin-Yu Lin, Ta-Chuan Tuan, Yenn-Jiang Lin, Shih-Lin Chang, Li-Wei Lo, Yu-Feng Hu, Fa-Po Chung, Shih-Ann ChenAbstractAtrial fibrillation (AF) has become the most prevalent arrhythmia and it will increase the risk of ischemic stroke, heart failure, mortality, sudden cardiac death, myocardial infarction, and dementia. Stroke prevention with oral anticoagulant is crucial for management of AF patients. Vitamin K antagonist, which inhibits the clotting factors II, VII, IX and X, has been recommended for stroke prevention for decades. Non-Vitamin K antagonist oral anticoagulants (NOACs), including dabigatran, rivaroxaban, apixaban and edoxaban are at least as effective as warfarin in reducing ischemic stroke with a lower rate of major bleeding. With the increasing prevalence of AF, prescription of the appropriate oral anticoagulants (OACs) according to patient's characteristics becomes a challenge. This review article aims to provide an overview of anticoagulant use in AF patients with difficult scenarios.

CONCLUSIONS: Currently, available evidence does not unequivocally support the clinical effectiveness of andexanet alfa or prothrombin complex concentrate to reverse factor Xa inhibitor-associated acute major bleeding, nor does it permit conventional meta-analysis of potential superiority. Neither reversal agent was significantly associated with increased effectiveness or a higher rate of venous thromboembolic event. These results underscore the importance of randomized controlled trials comparing the two reversal agents and may provide guidance in designing institutional guidelines.

AbstractCardiovascular disease (CVD) has long been the leading cause of death worldwide, and myocardial infarction (MI) accounts for the greatest proportion of CVD. Recent research has revealed that inflammation plays a major role in the pathogenesis of CVD and other manifestations of atherosclerosis. Overwhelming evidence supports the view that macrophages, as the basic cell component of the innate immune system, play a pivotal role in atherosclerosis initiation and progression. Limited but indispensable resident macrophages have been detected in the healthy heart; however, the number of cardiac macrophages significantly ...

Conclusions: Many unnecessary tests are obtained to evaluate syncope. Selecting tests based on history and examination and prioritizing less expensive and higher yield tests would ensure a more informed and cost-effective approach to evaluating older patients with syncope._____________________________________________________________________________4)    Reed MJ.  The ROSE (Risk Stratification of syncope in the emergency department) Study.  J Am Coll Cardiol, 2010; 55:713-721, doi:10.1016/j.jacc.2009.09.049  Objectives: The aim of this study was to develop and validate a clinical deci...
