Patients may develop heart problems caused by damage to small (microvascular) blood vessels. Eplerenone, a mineralocorticoid receptor-selective antagonist, reduces blood vessel injury and is used to treat high blood pressure and heart failure.\n\nAim: to test the use of eplerenone in patients with heart attack\u002Fheart injury an no obstructive coronary arteries and small vessel problems (coronary microvascular dysfunction).\n\nPatients admitted to hospitals in the West of Scotland (2.5 million) and referred for invasive management to the Golden Jubilee and Hairmyres hospitals because of a suspected heart attack heart 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 invited to participate in 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 \\\u003C2.0), microvascular resistance reserve ratio (MRR, abnormal \\\u003C2.5), and resistance reserve ratio (RRR abnormal \\\u003C2.0), measured simultaneously with IMR, are predefined parameters of interest.\n\nPatients will be allocated into one of the 3 groups:\n\n* Group 1: Patients without coronary microvascular dysfunction. No eplerenone\n* Group 2: Patient with coronary microvascular dysfunction. Usual care, no eplerenone.\n* Group 3: Small vessels abnormal. Eplerenone tablets.\n\nThe 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.\n\nThe 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 endotypes of myocardial infarction or injury with no obstructive coronary arteries.",[27,28,29],"Myocardial Infarction, Acute","Myocardial Infarction With Nonobstructive Coronary Arteries","Myocardial Injury",[31,32,33,34,35,36],"Stratified Medicine","Mineralocorticoid receptor antagonists","MINOCA","Myocardial injury","Myocardial infarction","Myocardial Infarction with Nonobstructive Coronary Arteries","RECRUITING","2026-03-12",{"date":40,"type":41},"2026-03-16","ACTUAL",{"date":43,"type":41},"2022-02-04",{"date":45,"type":21},"2026-07-31",{"name":47,"class":48},"NHS National Waiting Times Centre Board","OTHER",{"id":50,"slug":51,"hasResults":11,"nctId":52,"briefTitle":53,"officialTitle":54,"acronym":55,"eligibilityCriteria":56,"healthyVolunteers":11,"sex":17,"minAge":57,"maxAge":58,"enrollmentInfo":59,"targetDuration":4,"studyType":22,"phases":61,"briefSummary":63,"conditions":64,"keywords":4,"overallStatus":37,"whyStopped":4,"lastUpdateSubmitDate":65,"lastUpdatePostDateStruct":66,"startDateStruct":68,"completionDateStruct":70,"leadSponsor":72,"locationsCount":74},"100472017","stockholm-myocardial-infarction-with-nonobstructive-coronaries-study-3-100472017","NCT05426408","Stockholm Myocardial Infarction with Nonobstructive Coronaries Study 3","Stockholm Myocardial Infarction with Nonobstructive Coronaries Study 3 - Pilot Study of Prevalence of Coronary Microvascular Dysfunction in Myocardial Infarction with Nonobstructive Coronary Arteries","SMINC-3","Inclusion Criteria:\n\n* a suspected diagnosis of MINOCA or takotsubo syndrome with coronary angiography without diameter stenosis ≥50%\n* age 35-80 years\n* reading and writing proficiency in Swedish\n\nExclusion Criteria:\n\n* Claustrofobia\n* Arrythmia and\u002For pacemaker (atrial fibrillation and AV-block I- III)\n* Asthma or severe chronic obstructive lung disease\n* eGFR \\\u003C 30 ml\u002Fmin\n* spontaneous coronary artery dissection\n* acute pulmonary embolism\n* acute myocardial infarction type 2\n* cardiomyopathy other than takotsubo syndrome\n* a previous myocardial infarction due to CAD","35 Years","79 Years",{"count":60,"type":21},85,[62],"NA","The present pilot study will investigate the prevalence of CMD in an unselected cohort of patients with the working diagnosis MINOCA and to study if the diagnostic yield can be improved by adding adenosine to the CMR investigation.
