INTRODUCTION The CHA2DS2-VASc score is widely used for stroke risk stratification in patients with atrial fibrillation (AF). Our endpoints were to evaluate in an old population undergoing electrical cardioversion (ECV) of persistent AF if the CHA2DS2-VASc was associated with some of the Geriatric Multidimensional Assessment tools and with the presence of sinus rhythm at the follow-up. METHODS We enrolled all the consecutive patients admitted in a day-hospital setting aged ≥60 years. The Mini-Mental State Examination (MMSE; neurocognitive function), the 15-item Geriatric Depression Scale (GDS; depressive symptoms) and the Short Physical Performance Battery (SPPB; physical functioning) were administered before ECV. RESULTS Between 2017 and 2019, 134 patients were enrolled (mean age: 77±9 years, range: 60-96; men: 63.4%; EF: 60±12%). Hypertension was the most frequent comorbid condition (82.1%). The CHA2DS2-VASc score was 3.8±1.6. Abnormal values of MMSE, GDS and SPPB were observed in 7.9, 19.8 and 22.3% of cases, respectively. There were significant correlations between the CHA2DS2-VASc score and the MMSE (p=0.008), the GDS (p<0.001) and the SPPB (p<0.001). Depressive symptoms increased CHA2DS2-VASc correlation with SPPB of about 20%. CHA2DS2-VASc score was higher in patients with arrhythmia relapse (p=0.048; mean length of follow-up: 195 days). This association persisted even after adjustment for amiodarone therapy. CONCLUSIONS The CHA2DS2-VASc score significantly correlated with neuro-cognitive performance, depressive symptoms and physical functioning. It was also associated with AF relapse. Accordingly, in the elderly, the CHA2DS2-VASc could help quantify thrombo-embolic risk, give an indication of frailty status and help to choose between a rate- and a rhythm-control strategy.
