Myocardial Ischaemia National Audit Project (MINAP)
The Myocardial Ischaemia National Audit Project (MINAP) is a domain within the National Cardiac Audit Programme (NCAP) that contains information about the care provided to patients who are admitted to hospital with acute coronary syndromes (heart attack).
What is a heart attack?
A heart attack is a medical emergency, and you should call 999 for an ambulance immediately. It happens when there’s a sudden loss of blood flow to a part of the heart muscle. Without enough blood and oxygen your heart can be seriously damaged.
Myocardial Ischaemia National Audit Project (MINAP)
Data is collected and analysed to illustrate the ‘patient journey’ from a call to the emergency services or their self-presentation at an Emergency Department, through diagnosis and treatment at hospital, to the prescription of preventive medications on discharge. Provision of care by staff practising in participating hospitals, and, where relevant, ambulance trusts, is expressed through clinically important quality improvement/assurance indicators. The current analysis is for heart attacks admitted to hospital during the 12 months between 1 April 2024 and 31 March 2025. Hospital and Ambulance Trust performance, with respect to a number of aspects of care, are presented in tabular form in our interactive report.
MINAP works closely with the British Cardiovascular Society (BCS) – the body that represents and supports those professionals who work in cardiology in the UK. BCS maintains close links with patients and carers of patients with cardiac disease, and with cardiac nurses and physiologists.

STEMI & NSTEMI heart attacks
Based upon electrical heart tracings – electrocardiograms or ECGs recorded during a heart attack, patients are diagnosed as having suffered either ST-elevation myocardial infarction (STEMI) or non-ST elevation myocardial infarction (NSTEMI). The management of these two forms of heart attack are broadly similar yet include important early differences.
In the annual NCAP report, the terms ‘higher-risk’ and ‘lower-risk’ have been used to differentiate STEMI from NSTEMI. Those with ST-segment elevation are most likely to have complete or nearly complete blockage of one or more coronary arteries and require primary angioplasty. Higher-risk heart attacks in the report therefore refer to STEMI – patients who are at high risk of substantial heart muscle damage or early death. Lower-risk heart attacks in the report therefore refer NSTEMI – though, because patients with NSTEMI tend to be significantly older and have more co-morbid conditions than those with STEMI, over a one-year period the risk of death is about the same in both groups.
