Key result
Higher AF symptom severity is linked to poor sleep quality, reaching ~62% in EHRA IV.
Why the study?
Poor sleep quality is common in atrial fibrillation patients and its prevalence in relation to symptom severity assessed by the EHRA score was not well characterized.
Population
177 consecutive hospitalized patients with non-valvular AF without recent MI, stroke, or heart failure decompensation
Comparison
Poor sleep quality prevalence according to EHRA symptom severity score
Design
Cross-sectional study

Poor sleep quality prevalence rises with EHRA symptom severity in AF; supports assessment in symptomatic patients but leaves causal impact and interventions open.
Cross-Sectional (n=177)
p-value: p=0.01
Poor sleep quality affects approximately half of patients with non-valvular atrial fibrillation and its prevalence significantly increases with worsening symptom severity as measured by the EHRA score.
Szymański et al. (2014) conducted a cross-sectional in Atrial fibrillation (n=177). Atrial fibrillation symptom severity (EHRA score) vs. Lower EHRA score was evaluated on Poor sleep quality (assessed by PSQI) (p=0.01). Higher atrial fibrillation symptom severity (EHRA score) was significantly associated with an increased prevalence of poor sleep quality, rising from 33.3% in EHRA I to 61.5% in EHRA IV (P=0.01 for trend).
