Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Aim: to test the use of eplerenone in patients with heart attack/heart injury who have small vessel disease, including patients with COVID-19
Patients referred to the Golden Jubilee hospital with a suspected heart attack heart / injury will be invited to participate into a registry-based clinical trial. Screening, enrolment and verbal, informed consent will be obtained during the angiogram then written consent on the ward. Small vessel disease will be assessed using a 'diagnostic' guidewire during the standard angiogram. People with small vessel problems will be allocated to a clinical trial of usual care or eplerenone. Coronary microvascular dysfunction is defined as an index of microvascular resistance ≥25. Coronary flow reserve (CFR abnormal \<2.0) and resistance reserve ratio (RRR abnormal \<2.0), measured simultaneously with IMR, are predefined parameters of interest.
Patients will be allocated into one of the 3 groups:
* Group 1: Patients without coronary microvascular dysfunction. No eplerenone
* Group 2: Patient with coronary microvascular dysfunction. Usual care, no eplerenone.
* Group 3: Small vessels abnormal. Eplerenone tablets.
The primary outcome for the trial will be reduced heart injury (biomarkers) in patients with microvascular disease. We will also test heart function (MRI scan) at enrolment and at six months. All patients (Groups 1, 2 and 3) will have an angiogram. Standard blood tests will be collected during the hospital stay, and then again at 1 and 6 months. Other outcomes include questionnaires (health status). We will gather information on longer-term health outcomes (hospitalisation, death) using confidential electronic record linkage. We will ask for permission to store blood samples for future research.
The research will improve scientific knowledge about eplerenone therapy in this patient group. The study will create a repository of clinical samples and images which will provide vital data for studies of COVID-19.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Stratified medicine is defined by the Medical Research Council Framework (2015) as the identification of key sub-groups of patients within a heterogeneous population; these being distinguishable groups with differing mechanisms of disease, or particular responses to treatments. Stratification can be used to improve mechanistic understanding of disease processes and enable: the identification of new targets for treatments; the development of biomarkers for disease risk, diagnosis, progression and response to treatment; and treatments to be tested and applied in the most appropriate patient groups.
Objective: To implement stratified medicine in MINOCA.
Hypothesis: In MINOCA, early risk stratification by coronary microvascular dysfunction (index of microvascular resistance (IMR) ≥25) coupled with cardio-protective MRA therapy using eplerenone limits myocardial damage reflected by changes in N-terminal (NT)-pro hormone BNP (NT-proBNP).
Aim: To undertake a developmental clinical study, clarify evidence-gaps and provide training in academic cardiology. Prospective randomized open, blinded end-point (PROBE) design: Step-1: Screening in during coronary angiography of patients with acute myocardial infarction including MINOCA without heart failure or left ventricular ejection fraction ≤40%; Step-2: Guidewire-based measurement of microvascular resistance (culprit artery or if unknown, the left anterior descending coronary artery. Registry population, n=300); Step-3: Stratify subgroup with -increased vascular risk (IMR≥25) (Trial, n=150 eligible for MRA, informed consent); Step-4: Randomise this higher-risk group: eplerenone 25-50 mg daily for 6 months or standard care. Coronary physiology parameters including coronary flow reserve (CFR abnormal \<2.0), the resistance reserve ratio (RRR abnormal \<2.0) and left ventricular end-diastolic pressure will be prospectively measured.
Outcomes: Primary: within-subject change in NT-proBNP by group; Secondary: left ventricular ejection fraction; left ventricular volumes; patient reported outcome measures (PROMS). Value: Evidence-synthesis on stratified medicine for MINOCA.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Eplerenone
Patients with MINOCA and an index of microvascular resistance (IMR) greater than or equal to 25 will be randomised to receive eplerenone (starting dose 25 mg, uptitrated to 50mg after two weeks) for six months or standard of care and research protocol study visits. Patients who are screened, give informed consent but are not randomized will enter a followup registry.
Stratified medicine - Microvascular dysfunction and eplerenone therapy, tablets
Stratified medicine including interventional diagnostic procedure (IDP) and linked treatment with eplerenone. Patients with an increased IMR (strata with microvascular dysfunction, IMR ≥25) will be eligible for randomization to this arm. Patients randomized to receive eplerenone will be commenced on 25 mg once daily, and uptitrated to 50 mg once daily after two weeks. Treatment will be continued for a period of six months.
Standard of care
Patients with MINOCA and an index of microvascular resistance (IMR) greater than or equal to 25 will be randomised to receive eplerenone (starting dose 25 mg, uptitrated to 50 mg after two weeks) for six months or standard of care and research protocol study visits. Patients who are screened, give informed consent but are not randomized will enter a followup registry.
Stratification and standard care
Interventional diagnostic procedure (IDP) without linked treatment i.e., standard care. Patients with an increased IMR (strata with microvascular dysfunction, IMR ≥25) will be eligible for randomization to this arm. In the standard care group, the IDP is performed but the results are not disclosed. The IDP is therefore a sham procedure. Patients randomized to receive eplerenone will be commenced on 25 mg once daily, and uptitrated to 50 mg once daily after two weeks. Treatment will be continued for a period of six months.
