Racial Differences in the Prevalence and Outcomes of Atrial Fibrillation Among Patients Hospitalized With Heart Failure
Background The intersection of heart failure (HF) and atrial fibrillation (AF) is common, but the burden of AF among black patients with HF is poorly characterized. We sought to determine the prevalence of AF, characteristics, in‐hospital outcomes, and warfarin use associated with AF in patients hospitalized with HF as a function of race.
Methods and Results We analyzed data on 135 494 hospitalizations from January 2006 through January 2012 at 276 hospitals participating in the American Heart Association’s Get With The Guidelines HF Program. Multivariable logistic regression models using generalized estimating equations approach for risk‐adjusted comparison of AF prevalence, in‐hospital outcomes, and warfarin use. In this HF population, 53 389 (39.4%) had AF. Black patients had markedly less AF than white patients (20.8% versus 44.8%, P<0.001). Read More
