Study summary

Myocardial infarction with non-obstructive coronary arteries" (MINOCA) occurs in 5-10% of all patients with AMI. There are neither any randomized clinical trials in MINOCA patients evaluating effects of secondary preventive treatments proven beneficial in patients with classic AMI, nor any treatment guidelines.

The primary objective of this multi-national, multi-center pragmatic randomized clinical trial is to determine whether oral beta-blockade compared to no oral beta-blockade, and whether Angiotensin Converting Enzyme Inhibitors (ACEI/ Angiotensin Receptor Blockers (ARB) compared to no ACEI/ARB, reduce the composite endpoint of death of any cause and readmission because of AMI, ischemic stroke or heart failure in patients discharged with myocardial infarction with non-obstructive coronary artery disease (MINOCA) and with no clinical signs of heart failure and with left ventricular (LV) systolic ejection fraction ≥40%.

Read the detailed description

Large-scale use of acute coronary angiography has revealed a large portion of AMI without angiographically obstructive (defined as ≥50% diameter stenosis) coronary artery disease (CAD). The term "myocardial infarction with non-obstructive coronary arteries" (MINOCA) has been coined for this entity. MINOCA occurs in 5-10% of all patients with AMI and these patients are younger and more often females compared to patients with AMI and obstructive CAD. The 1-year mortality after MINOCA was found to be 3.5% in the systematic review by Pasupathy et al.. There are no randomized clinical trials in MINOCA patients evaluating effects of secondary preventive treatments proven beneficial in patients with classic AMI. However, in an observational study with propensity score matched comparisons the risk of experiencing a Major Adverse Cardiac Event (MACE) was 18% lower in patients treated with ACEI/ARB compared to no ACEI/ARB; in patients on beta blockers compared to patients not using beta blockers there was a non-significant 14% reduction in MACE.

The primary objective of this multi-national, multi-center pragmatic randomized clinical trial is to determine whether oral beta-blockade compared to no oral beta-blockade, and whether ACEI/ARB compared to no ACEI/ARB, reduce the composite endpoint of death of any cause and readmission because of AMI, ischemic stroke or heart failure in patients discharged with myocardial infarction with non-obstructive coronary artery disease (MINOCA) and with no clinical signs of heart failure and with LV systolic ejection fraction ≥40%.

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Individual participant data

Plan to share: Yes — We will make a limited, de-identified set of data available for researchers outside the primary investigators two years after the publication of the primary results of the study. Before data are shared, a data-sharing agreement should be established documenting what data are being shared and how the data can be used. The agreement serves two purposes. First, it protects the agency providing the data, ensuring that the data will not be misused. Second, it prevents miscommunication on the part of the provider of the data and the agency receiving the data by making certain that any questions about data use are discussed. The following items should be covered in the data-sharing agreement: Period of agreement Intended use of the data Constraints on use of the data Data confidentiality Data security Methods of data-sharing

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 27, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
