Study	Reason for exclusion
CAPRICORN 2001	Participants with heart failure and LVEF < 40% were included
COMMIT 2005	Patients were followed only during the acute phase after myocardial infarction; hence, follow‐up was limited to 1 month
Mazur 1994	This was not a randomised controlled trial
Mickley 1991	Patients did not receive any intervention with beta‐blockers
Park 2013	Most included patients had a history of stable angina pectoris ‐ not myocardial infarction
Smith 2008	This was a cluster randomised trial

LVEF: left ventricular ejection fraction.
