ABSTRACT
BACKGROUND AND AIMS:
Atrial fibrillation (AF) is the most frequent arrhythmia of the elderly, and electrical cardioversion (ECV) is a common procedure, although incidence of recurrences remains high. We evaluated the possible association between arterial stiffness (AS) and the persistence or recurrence of AF in elderly patients after ECV.METHODS:
We enrolled all subjects undergoing ECV over a 9-month period. AS was evaluated with the cardio-ankle vascular index (CAVI). Patients were then visited at follow-up (on average at 6 months).RESULTS:
Thirty-one patients (age 78 ± 7 years; men 67.7 %; CHA2DS2-VASc 4.1 ± 1.6; AF length >2 months 51.6 %; CAVI 9.9 ± 1.6) underwent ECV. At follow-up, sinus rhythm was recorded in 16 (51.6 %) patients. At multivariate analysis, the presence of AF was directly associated with CHA2DS2-VASc score and CAVI. Amiodarone therapy reduced the risk of relapsed AF.CONCLUSIONS:
In elderly AF patients treated with ECV, AS at baseline seems to predict AF at follow-up.Palavras-chave
