Key result
Beta-blocker treatment in heart failure patients improved left ventricular ejection fraction, with mean increases of 7.4 units for metoprolol, 5.7 for carvedilol, and 4.6 for bucindolol.
Why the study?
Does beta-blocker treatment improve ejection fraction differently depending on the specific agent or etiology in patients with heart failure?

Beta-blockers improve LVEF across agents in HF; confirms class effect on remodeling while survival differences arise via other mechanisms.
Systematic Review
Does beta-blocker treatment improve ejection fraction differently depending on the specific agent or etiology in patients with heart failure?
Beta-blockers consistently improve ejection fraction in heart failure patients regardless of the specific agent, suggesting that observed survival differences between agents are mediated by mechanisms other than LV function improvement.
CAMPEN et al. (1998) conducted a systematic review in Heart failure. Beta-blockers vs. Various beta-blockers and etiologies was evaluated on Improvement in ejection fraction (EF). Beta-blocker treatment in heart failure patients improved left ventricular ejection fraction, with mean increases of 7.4 units for metoprolol, 5.7 for carvedilol, and 4.6 for bucindolol.
