Overview
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).
Description
Pragmatic, controlled, prospective, randomized, open-label, blinded endpoint clinical trial testing the benefits of beta-blocker maintenance therapy in patients discharged after an acute myocardial infarction (MI). Patients being discharged after an acute MI, with or without ST-segment elevation, and with a left ventricular ejection fraction >40%, and without history of heart failure (HF) prior to study inclusion, will be recruited. At discharge, patients will be randomized (1:1) to receive beta-blocker therapy (agent and dose according to treating physician) or no beta-blocker therapy. Primary outcome is the 5 years incidence of MACE (all cause mortality, reinfarction, heart failure admission).
Eligibility
Inclusion Criteria:
- ≥18 years old
- Admitted for STEMI or NSTEMI and invasive management (i.e. coronary angiography during index hospitalization).
- LVEF>40% as evaluated by any imaging technique anytime during hospitalization.
- Signed informed consent
Exclusion Criteria:
- Known allergy or intolerance to beta-blockers
- Absolute contraindication to beta-blocker therapy according to treating physician judge
- Prior history of HF, Killip class on admission or during hospitalization ≥ II
- Severe valvular heart disease (> 3+ for aortic or mitral insufficiency, aortic or mitral valve area ≤1.0 cm2).
- Any condition (appart from AMI) that requires beta-blocker prescription on discharge according to treating physician judge
- Any medical condition that, in the investigator´s judgment, would seriously limit life expectancy (less than one year),
- Patients participating in other clinical trials
