Role of beta-blockers in patients admitted for worsening heart failure in a real world setting: data from the Italian Survey on Acute Heart Failure.

Aims: Randomized trials have shown that beta-blockers (BBs) reduce mortality in chronic heart failure (HF). Less data are available on the role of BBs in patients with acute HF, specifically if BBs should be continued or temporarily withdrawn. The aim of this study was to evaluate the role of BBs on in-hospital outcomes of patients admitted for worsening HF in a Cardiology setting.
