Outcome Measures

Primary Outcomes (1)

  • A composite of death of any cause, recurrent myocardial infarction, incident heart failure, coronary revascularization, ischemic stroke, malignant ventricular arrhythmia including resuscitated cardiac arrest of cardiac origin

    Incidence of combined endpoint from randomization. Estimated maximal follow-up for each patient for this outcome is 6 months to 6 years

    6 months (minimum) to 6 years (maximum)

Secondary Outcomes (18)

  • Recurrent MI

    6 months (minimum) to 6 years (maximum)

  • All-cause death

    6 months (minimum) to 6 years (maximum)

  • Malignant ventricular arrhythmias including resuscitated cardiac arrest of cardiac origin

    6 months (minimum) to 6 years (maximum)

  • Hospitalization or outpatient consultation for incident heart failure

    6 months (minimum) to 6 years (maximum)

  • Unplanned coronary revascularization

    6 months (minimum) to 6 years (maximum)

  • +13 more secondary outcomes

Study Arms (2)

Betablocker

ACTIVE COMPARATOR

Patients receiving a betablocker. Any other treatment or management is to be given as per usual care.

Drug: Betablocker

Non-Betablocker

EXPERIMENTAL

No betablocker is given to this arm. Any other treatment or management is to be given as per usual care.

Other: Non-betablocker

Interventions

No betablocker will be administered. Patients randomized to no beta-blockade will be discouraged to use beta-blockade as long as there is no other indication than strictly secondary prevention after myocardial infarction. Any other treatment or management is to be given as per usual care.

Non-Betablocker

A betablocker will be administered. To reflect contemporary management, for which this study is designed to test, there will not be a defined minimum dosage. The type and dose of BB will be left at the discretion of the PI. Generic drug and accepted dosages will be: * Metoprolol succinate up to a total dose of 200mg daily * Bisoprolol up to a total dose of 10mg daily * Carvedilol up to a total dose of 50mg daily The treating physician will be encouraged to aim for an equipotent dose of 100 mg metoprolol succinate or higher. Any other treatment or management is to be given as per usual care.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • years or older
  • Diagnosed with an acute MI type I according to the "Universal Definition of MI" (Defined as a detection of a rise and/or fall of cardiac biomarker value, preferably troponin, with at least one value above the 99th percentile upper reference limit and with at least one of the following; a) symptoms of ischemia, b) new or presumed new significant ST-segment-T wave changes or new left bundle branch block, c) development of pathological Q waves, d) imaging evidence of new loss of viable myocardium or e) identification of an intracoronary thrombus by coronary angiogram)
  • Must have been treated with PCI or thrombolysis during current hospitalization
  • Signed informed consent and expected cooperation of the patient according to ICH/GCP and national/local regulations
  • Have a national personal identification number and not be expected to emigrate during study

You may not qualify if:

  • Study subjects must not meet any of the following criteria:
  • Having a condition where betablocker-therapy is required, including but not limited to:
  • Arrhythmias
  • Hypertension
  • Cardiomyopathies
  • Clinical diagnosis of heart failure
  • LVEF \< 40% by echocardiography (by measurement and not only visual assessment for STEMI patients)
  • Left ventricular akinesia in ≥ 3 segments regardless of the LVEF
  • Contraindications to betablocker-therapy, including but not limited to:
  • Bradyarrhythmias
  • Hypotension
  • Severe peripheral artery disease
  • Previously known side-effects causing withdrawal
  • Severe chronic obstructive pulmonary disease
  • Women of childbearing potential (a woman is considered of childbearing potential, i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile)
  • +3 more criteria
