CHADS2 and CHA2DS2-VASc Scores in the Prediction of Clinical Outcomes in Patients With Atrial Fibrillation After Catheter Ablation

Abstract

The CHADS(2) and CHA(2)DS(2)-VASc scores are useful predictors of adverse events after catheter ablation of AF.

Catheter Ablation of Lone Atrial Fibrillation

“…Adverse events were more common among patients with AF recurrence than among those who were free of AF score ≤1, the risk of adverse events gradually increased, in parallel with the value of CHA 2 DS 2 -VASc score (0.6% for score 0, 1.6% for score 1, 6.2% for score 2 and 11.8% for score 3) [156]. Therefore, it seems that the CHA 2 DS 2 -VASc scoring system is more sensitive (than CHADS 2 ) for assessment of thromboembolic risk after catheter ablation of AF.…”

“…Over the long term follow-up period of 38 months after AF ablation, 4.8% of a total of 565 study patients have suffered some adverse event, including thromboembolism [156].…”

“…As already mentioned, several recent studies suggested potential value of CHA 2 DS 2 -VASc score in further stratification of so called "low risk" patients (based on a low CHADS 2 score of 0-1) after catheter ablation of AF. Thus, despite low CHADS 2 score, in patients with a CHA 2 DS 2 -VASc score of ≥2 and/or recurrence of AF, long term anticoagulation after the procedure should be considered [156,157].…”

EHRA/HRS/APHRS/SOLAECE expert consensus on atrial cardiomyopathies: definition, characterization, and clinical implication

“…However, late recurrences are common and associated with more advanced atrial substrate associated with structural heart disease. [436][437][438][439][440][441][442][443][444][445][446] It is in this context that it is important to consider the various types of underlying atrial cardiomyopathy and how they may affect ablation outcomes. This is timely, as it has recently been observed that lone AF is a rapidly disappearing entity as we recognize conditions such as sleep apnoea, obesity, endurance exercise etc.…”

“…Для оценки риска инсульта и тромбоэмболиче-ских событий у пациентов с ФП использовалась шкала CHA 2 DS 2 [5] и ее новая модификация CHA 2 DS 2 -VASc [6], которая лучше подходит для оценки риска инсульта и тромбоэмболических собы-тий у пациентов с ФП, особенно в группе пациентов с низким риском.…”
