Heart failure is a leading cause of death and hospitalization in the US. Designing practical approaches to improving heart failure care is therefore a national health priority. One retrospective study suggested that patients taking beta-blockers while hospitalized for heart failure had a lower risk of rehospitalization at 6-months. One prospective study suggested that starting beta blockers among hospitalized heart failure patients is safe and improves compliance. However, improved outcomes of this approach have not been prospectively demonstrated.
