Figure 2 Overview of Major Meta-Analyses of Randomized Controlled Trials of Beta-Blockers in Patients With Heart Failure

In patients with heart failure, beta-blockers are efficacious agents for the prevention of cardiovascular events. ACEi = angiotensin-converting enzyme inhibitors; ARBs = angiotensin receptor blockers; BB = beta-blocker; CI = confidence interval; HR = hazard ratio; LVEF = left ventricular ejection fraction; NYHA = New York Heart Association.
