Discontinuation of β-blockers in stable patients with previous myocardial infarction, preserved left ventricular ejection fraction, and no heart failure: a pooled analysis of individual patient data.
In stable patients with previous myocardial infarction, left ventricular ejection fraction ≥40%, no heart failure, and no other indication for β-blocker therapy, discontinuation met the non-inferiority criteria for the primary and key secondary endpoints.
