Previous investigations have analysed the relationship between weekend (WE) admission and early death in patients with atrial fibrillation (AF) patients without reaching univocal results. We systematically reviewed the available literature and performed a meta-analysis of data from cohort studies to estimate the association between WE admission and short-term mortality in AF patients. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. We searched relevant publications using MEDLINE and Scopus from inception until 15 November 2022. Studies reporting the mortality risk as an adjusted odds ratio (OR), with relative 95% confidence interval (CI) comparing early (in‐hospital or 30‐day) mortality between patients admitted during the WE (Friday to Sunday) versus weekdays (WD) and having confirmed AF were included into the analysis. Data were pooled using a random-effects models with OR and related 95% CI. Overall, 5.164.986 AF patients (mean age 69.7 years old, 47.6% males) enrolled in five retrospective investigations were considered for the analysis. A random-effect model evidenced that AF patients admitted during the WE had a higher risk of 30-day or in-hospital death (adjusted OR: 1.57; 95% CI, 1.05–1.27,  p  = .003, I2 = 64.7%). Sensitivity analysis confirmed yielded results. A meta-regression analysis showed a relationship between mortality and the mean age of the studies included ( p  = .001) while no associations were identified using sex as moderating variables ( p  = .15). Patients admitted during WE for AF are characterised by an approximately 58% excess in the risk of early death.
