Design
Randomised (allocation concealed*), blinded (clinicians and patients),* placebo controlled trial with mean follow up of 2 years (Beta-Blocker Evaluation of Survival Trial [BEST]).
Setting
90 clinical sites in the USA and Canada.

Inclusion criteria were New York Heart Association (NYHA) class III or IV chronic heart failure caused by primary or secondary dilated cardiomyopathy; left ventricular ejection fraction ≤ 35%; optimal medical treatment, including angiotensin-converting enzyme inhibitors for ≥ 1 month; and ≥ 18 years of age. Exclusion criteria included reversible heart failure; uncorrected primary valvular disease; active myocarditis; recent myocardial infarction or revascularisation; unstable angina; heart rate < 50 beats/minute; or serious concomitant illness.
Intervention
Patients were allocated to bucindolol, 3 mg twice daily for 1 week, which was then titrated gradually to a maximum dose of 100 mg twice daily (n=1354) or to placebo (n=1354).
