Biomarkers and Risk Prediction Tools for Stroke and Dementia in Patients with Atrial Fibrillation

AbstractPurpose of ReviewWith the aging population, atrial fibrillation (AF) associations with both stroke and dementia have become a priority for the healthcare system. The purpose of this paper is to review the emerging role of clinical scores and biomarkers in the risk stratification of AF patients for risk of stroke and risk of dementia.Recent FindingsAF is the most common arrhythmia in the aging population and a common comorbidity in atherosclerotic disease and heart failure. In this review, we identified 34 most relevant papers that specifically address the role of biomarkers in risk-stratifying patients with AF with regard to stroke and dementia. Recent data suggest an incremental value for biomarkers of myocardial injury, myocardial strain, and hemostasis for risk-stratifying patients at risk with AF at greater risk of stroke. Furthermore, biomarker risk scores such as the Intermountain Risk Score are emerging as complementary to the commonly used CHA2DS2-VASc score for both stroke and dementia. Imaging biomarkers including left atrial size and left atrial reservoir strain may complement these circulating biomarkers to identify patients at greater risk of stroke, and the combination of AF and evidence of subclinical stroke could further inform the risk cognitive decline.SummarySeveral clinical biomarker risk scores and biomarkers can complement the risk stratification of AF and dementia. With the more frequent use of anticoagulation, developing integrated risk scores ...

Authors: Sabet Sarvestani F, Azarpira N Abstract Heart and cerebral infarctions, as two important ischemic diseases, lead to the death of tissues due to inadequate blood supply and high mortality worldwide. These statuses are started via blockage of vessels and depletion of oxygen and nutrients which affected these areas. After reperfusion and restoration of oxygen supply, more severe injury was mediated by multifaceted cascades of inflammation and oxidative stress. microRNAs (miRNAs) as the regulator of biological and pathological pathways can adjust these conditions by interaction with their targets. Also, miRNAs...

Authors: Zhao N, Xiang Q, Liu Z, Zhao X, Cui Y Abstract INTRODUCTION: There remains an unmet need for better anticoagulants. The phase I clinical trial is of great significance in the development of anticoagulants, and the design is special. This system review aims to provide insights for the design of future phase I clinical trials of anticoagulants. AREAS COVERED: We searched the database PubMed and ClinicalTrail.gov website, to collate the phase I clinical trial of anticoagulants in healthy people. The study protocol, inclusion exclusion criteria, safety and pharmacodynamic indexes were reviewed. EXPERT ...

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...
