Echocardiography for Embolic Risk Stratification in Atrial Fibrillation: Improvement of CHA2DS2-VASc in the Era of New Oral Anticoagulants
نویسنده
چکیده
It is well known that atrial fibrillation (AF) is the most frequent sustained cardiac rhythm disturbance, occurring in between 1 and 2% of the general population. AF confers a fivefold risk of stroke and one in five of all strokes plus an unknown number of “cryptogenic strokes” is attributable to AF. (1) The mean incidence of a disabling stroke in AF patients is 2.5%/ year, which increase to 7% if TIA and silent stroke are included. Therefore, in the management of antithrombotic therapy in patients with AF the balance between embolic and hemorrhagic risk is essential. In these patients the first task for the physician is the risk stratification for embolism and hemorrhage with all the available score systems. This is the basis for the “individualized antithrombotic therapy”, which sometimes remain an ideal goal, to best treat AF against the two great risks: cerebral embolism and major hemorrhages.

Stroke Risk Predictor Scoring Systems in Atrial Fibrillation.
An effective risk stratification which could help us identify high-risk patients who should take oral anticoagulants (OACs) is the key step for stroke prevention in atrial fibrillation (SPAF). Several scoring systems were available to estimate the risk of stroke in AF, including CHADS2, CHA2DS2-VASc, R2CHADS2 and ATRIA scores, which were constituted of different clinical risk factors. Recently,...
متن کاملIschemic Stroke Risk in Patients With Atrial Fibrillation and CHA2DS2-VASc Score of 1: Systematic Review and Meta-Analysis.
BACKGROUND AND PURPOSE The CHA2DS2-VASc score aims to improve risk stratification of ischemic stroke among patients with atrial fibrillation to identify those who can safely forego oral anticoagulation. Oral anticoagulation treatment guidelines remain uncertain for CHA2DS2-VASc score of 1. We conducted a systematic review and meta-analysis of the risk of ischemic stroke for patients with atrial...
متن کاملEffect of Metabolic Syndrome on Risk Stratification for Left Atrial or Left Atrial Appendage Thrombus Formation in Patients with Nonvalvular Atrial Fibrillation
BACKGROUND Metabolic syndrome (MS) is a risk factor for stroke and thromboembolism event. Left atrial or LA appendage (LA/LAA) thrombus is a surrogate of potential stroke. The relationship between MS and atrial thrombus remains unclear. In this study, we sought to investigate the effect of MS on risk stratification of LA/LAA thrombus formation in patients with nonvalvular atrial fibrillation (N...
متن کامل[Atrial fibrillation and stroke].
BACKGROUND More than 70,000 Norwegians have atrial fibrillation, which is a major risk factor for ischemic stroke. A large proportion of ischemic strokes caused by atrial fibrillation could be prevented if patients receive optimal prophylactic treatment. This article describes the risk for ischemic stroke in patients with atrial fibrillation, and discusses who should receive prophylactic treatm...
متن کاملRelationship of CHA2DS2-VASc and CHADS2 Score to Left Atrial Remodeling Detected by Velocity Vector Imaging in Patients with Atrial Fibrillation
BACKGROUND The CHADS2/CHA2DS2-VASc scores are used to predict thrombo-embolic/stroke in patients with nonvalvular atrial fibrillation (AF). Nevertheless, limited data are available regarding the association between these risk stratification for stroke and left atrial (LA) remodeling status of AF patients. The purpose of this study was to explore the association between these scores and LA remod...
