Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The specific brand of medication to be prescribed will be at the discretion of your cardiologist, but the type of drug will be a beta blocker, Angiotensin Converting Enzyme inhibitor (ACEI)/angiotensin receptor blocker (ARB). In Australia, commonly prescribed agents in these drug classes include atenolol, perindopril and candesartan.

The randomisation will be carried out using an online randomization module. Following the screening process, the investigator will discuss the suitability of the participant in the trial with the treating cardiologist. Following the approval from the treating cardiologist, the participant will be approached and consented for the trial. The randomization will be performed in the module using permuted block randomization with 1:1:1:1 ratio, stratified by country.

Group 1: Beta Blocker Alone (oral administration)
- Starting dose (first 2 weeks after the randomisation): Atenolol 25mg daily
- Target dose: Atenolol 50 mg daily

Group 2: ACEI or ARB Alone (oral administration)
- Starting dose (first 2 weeks after the randomisation): Perindopril Arginine 2.5mg daily (or alternatively Perindopril Erbumine 2mg daily) or Candesartan 4mg daily
- Target dose: Perindopril Arginine 10 mg daily (or alternatively Perindopril Erbumine 8 mg daily) or Candesartan 16mg daily

Group 3: Both Beta blocker and ACEI or ARB (oral administration)
- Starting dose (first 2 weeks after the randomisation): Atenolol 25mg daily + Perindopril Arginine 2.5mg daily (or alternative ACEI or
ARB as above)
- Target dose: Atenolol 50mg daily + Perindopril Arginine 10 mg daily (or alternative ACEI or ARB as above)

The suggested target dose escalation is at the treating physician's discretion.

Patients will be encouraged to continue the use of the randomized treatment following
discharge for the total study period (4 years) until contraindications.

Due to the pragmatic nature of this trial, the participant's compliance will be evaluated via follow-up telephone calls by the study coordinator. The study medications will be prescribed by the treating clinician, who will have a thorough understanding of the clinical trial, as part of their routine patient care. Participants will be asked to send their pharmacy receipts for the study drugs to the coordinating centre which will also provide an indication as to medication compliance

Composite of angina frequency, physical limitation, quality of life and patient satisfaction as scored by the Seattle Angina Questionnaire (SAQ)

The SAQ is a self-administered, disease-specific measure for patients with heart disease. The SAQ quantifies patients’ physical limitations caused by angina, the frequency of and recent changes in their symptoms, their satisfaction with treatment, and the degree to which they perceive their disease to affect their quality of life. Each scale is transformed to a score of 0 to 100, where higher scores indicate better function (eg, less physical limitation, less angina, and better quality of life).

Summary
Brief summary
Myocardial infarction with non-obstructive coronary arteries" (MINOCA) occurs in 5-10% of all patients with acute myocardial infarction (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 MINOCA and with no clinical signs of heart failure and with left ventricular (LV) systolic ejection fraction above or equal to 40%.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
Yes
What data in particular will be shared?
A limited, de-identified set of data available for researchers outside the primary investigators and will be specified in the data sharing plan.
When will data be available (start and end dates)?
Two years after the publication of the primary results of the study. The endpoint of the availability to be specified by the investigators.
Available to whom?
Researchers outside the primary investigators.
Available for what types of analyses?
The type of analyses must be specified in the data sharing agreement between the providing agency and the requesting researchers.
How or where can data be obtained?
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
The intended use of the data
Constraints on the use of the data
Data confidentiality
Data security
Methods of data-sharing
