Key result
A CHA2DS2-VASc score of 6 or higher was associated with a 61.3% prevalence of atrial fibrillation in patients hospitalized for decompensated heart failure.
Why the study?
Heart failure and atrial fibrillation are both epidemic, and the relationship between CHA2DS2-VASc score subgroups and the prevalence of atrial fibrillation in decompensated heart failure needed assessment.

Is the CHA2DS2-VASc score associated with the prevalence of atrial fibrillation in patients hospitalized for decompensated heart failure?
In patients hospitalized for decompensated heart failure, a higher CHA2DS2-VASc score (≥ 6) is significantly associated with a higher prevalence of atrial fibrillation.
BACKGROUND: Heart failure (HF) has become an epidemic. A similar situation is also observed for atrial fibrillation (AF). The CHA2DS2-VASc score is one of the most useful tools for thromboembolic risk assessment. AIM: The aim of the study was to assess the prevalence of AF in patients with decompensated HF, who were divided into subgroups according to the CHA2DS2-VASc score. METHODS: We analysed the prevalence of AF in a group of 1108 patients (327 women) hospitalised due to HF decompensa- tion in medical centres of different referral levels. Twenty-one patients refused to participate in the registry. The data were collected from Polish centres included in the European Society of Cardiology Heart Failure Long-Term Registry. The recruit- ment period was from 2011 to 2014. The data were analysed retrospectively. Patients were divided into groups according to the CHA2DS2-VASC score. RESULTS: The study sample was characterised by a high occurrence of AF (44.3%), with the highest prevalence in patients with a CHA2DS2-VASC score ≥ 6 (61.3%, p = 0.01). CONCLUSIONS: The CHA2DS2-VASc score may be a useful tool for detecting patients with HF characterised by the highest risk of AF.

Kuczaj et al. (2019) conducted a cross-sectional in Decompensated heart failure (n=1,108). CHA2DS2-VASc score ≥ 6 vs. CHA2DS2-VASc score 0-5 was evaluated on Prevalence of atrial fibrillation (p=0.01). A CHA2DS2-VASc score of 6 or higher was associated with a 61.3% prevalence of atrial fibrillation in patients hospitalized for decompensated heart failure.
