TREatment With Beta-blockers After myOcardial Infarction withOut Reduced Ejection fracTion"

REBOOT clinical trial will study whether long-term maintenance beta-blockers therapy results in a clinical benefit after heart attack without reduced left ventricular function. Half of the participants will be randomized to receive long-term beta-blocker therapy and the other half to no beta-blocker therapy after hospital discharge. All patients will be followed up for up to 5 years to determine the occurrence of adverse events (all cause mortality, re-infarction, and heart failure admission).
