Relationship between the CHA2DS2-VASc score and atrial fibrillation in patients hospitalised due to heart failure

Abstract

Background: Heart failure (HF) has become an epidemic. A similar situation is also observed for atrial fibrillation (AF). The CHA 2 DS 2 -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 CHA 2 DS 2 -VASc score. Methods:We analysed the prevalence of AF in a group of 1108 patients (327 women) hospitalised due to HF decompensation 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 recruitment period was from 2011 to 2014. The data were analysed retrospectively. Patients were divided into groups according to the CHA 2 DS 2 -VASC score. Results:The study sample was characterised by a high occurrence of AF (44.3%), with the highest prevalence in patients with a CHA 2 DS 2 -VASC score ≥ 6 (61.3%, p = 0.01). Conclusions:The CHA 2 DS 2 -VASc score may be a useful tool for detecting patients with HF characterised by the highest risk of AF.

Association of CHA2DS2-VASC Score with in-Hospital Cardiovascular Adverse Events in Patients with Acute ST-Segment Elevation Myocardial Infarction

“…e variables that comprise the CHA2DS2-VASc score have been extensively studied as risk factors for death and adverse events in patients with acute STEMI [17][18][19]. In addition, numerous studies have shown that that CHA2DS2-VASc score can predict the prognosis of patients with various cardiovascular diseases, regardless of atrial fibrillation [20][21][22][23]. In patients diagnosed with the acute coronary syndrome, the CHA2DS2-VASc score was also associated with adverse cardiovascular events.…”

Usefulness of CHADS2, R2CHADS2, and CHA2DS2‐VASc scores for predicting incident atrial fibrillation in heart failure with preserved ejection fraction patients

“…The prevalence of AF in patients with HFpEF might vary among the populations from different regions or ages 3 . Previously, Kuczaj et al 22 . found that the CHA2DS2‐VASc score could be used to detect patients with decompensated HF characterized by the highest prevalence of AF.…”

“…21 The prevalence of AF in patients with HFpEF might vary among the populations from different regions or ages. 3 Previously, Kuczaj et al 22 found that the CHA2DS2-VASc score could be used to detect patients with decompensated HF characterized by the highest prevalence of AF. In our study, the AF prevalence rates in HFpEF patients with a score of ≥3 increased in a graded manner across the CHADS2 (range: 39.1-56.7%), R2CHADS2 (range: 35.9-71.4%), or CHA2DS2-VASc (range: 28.0-50.0%) score categories.…”
