Using the MB-LATER score for predicting arrhythmia outcome after catheter ablation for atrial fibrillation: The Guangzhou atrial fibrillation project

Abstract

Several clinical scoring systems have been derived to predict the arrhythmia outcome of catheter ablation (CA) for atrial fibrillation (AF) but which is better is not clear. Simple clinical risk scores (that any clinician can use in the everyday clinic) can help assess the likelihood of recurrence of AF following CA and the simple MB-LATER score has recently been described. We compare the predictive ability of seven existing clinical scoring systems (HATCH, CHADS2 , CHA2 DS2 -VASc, BASE-AF2 , APPLE, CAAP-AF, and MB-LATER) in a Chinese cohort of AF patients undergoing CA. 1410 patients (mean age 57.2 ± 11.6 years; 68% male) with AF undergoing CA during 2011-2015 were enrolled in final analysis. Symptoms, 12 lead ECG and Holter ECGs were recorded before discharge, and at 1, 3, 6 months, and every 6 months thereafter to detect the arrhythmia relapse. During a mean 20.7 ± 8.8-month follow-up, recurrence occurred in 365 patients(25.9%). All tested scores were predictors of AF recurrence with areas under the curve (AUCs) of 0.58, 0.57, 0.57, 0.75, 0.74, 0.71, and 0.73 respectively (all P < 0.01). Compared to all other scores, the MB-LATER score showed improved reclassification (NRI range 30%-82.6%, P < 0.01) and discrimination indexe...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
