Stratified Medicine of Eplerenone in Acute Myocardial Infarction or Injury and no Obstructive Coronary Arteries.

Patients with heart attack or heart injury are tested (angiogram) for blockages in their arteries. 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. Aim: to test the use of eplerenone in patients with heart attack/heart injury an no obstructive coronary arteries and small vessel problems (coronary microvascular dysfunction). Patients 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 \<2.0), microvascular resistance reserve ratio (MRR, abnormal \<2.5), 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: * …
