Observational studies have suggested that early discharge (24hrs with follow up virtually by telephone) of patients who are low risk and have had successful treatment following ST elevation myocardial infarction is safe. This has not been tested in a randomised controlled trial. In this trial the study team propose to identify low risk patients and randomise them to usual care or early discharge and follow up virtually by telephone. The primary endpoint would be readmission to hospital or all cause death up to 30 day following the event. If the outcome is positive, the study will assist early discharge of patients, reduce length of stay, potentially improve patient well being and have positive financial implications for the health service
