For the standard group and study participants the clinical records will be reviewed to check if any primary or secondary endpoints were met. They will be contacted at 30 days for a telephone consultation after the index event (time from when patient was admitted), and they will be asked to fill in a patient satisfaction questionnaire

Patients who are randomised to the study group will receive a blood pressure monitor and instructions on how to use the device and transfer data to the study team. The study nurses will contact the patient every day for 3 days following their discharge and perform an virtual ward round assessment by telephone (see table). This will determine whether the patient continues to be monitored via the virtual ward, or whether they need to be referred to the clinical team. They will be issued with an emergency contact number out of hours (coronary care unit LGI) and the nursing hub will operate from 8am to 5pm 7 days a week. They will be referred to the community cardiac rehabilitation service whilst on the pathway.

(time starts at admission of patient). No randomised controlled trials (RCTs) have compared 24-48 hours discharge to >48 hours discharge in low-risk STEMI patients. To the knowledge there has been a prior meta-analysis included 5 RCTs comparing discharge at 48 to 72 hours versus >72 hours and this was found to be safe(4). The 30-day event rate of any hospitalisation or all-cause death that was available from 3 RCTs was 31/489 (6.3%) in the routine care arm and 21/515 (4.1%) in the early discharge arm. For a non-inferiority design, assuming an event rate of 6% in the routine care arm and 4% in the very early discharge arm and a non-inferiority margin of 2.5%, 290 patients would be needed in each arm to provide 80% power, at 5% significance level. To allow for approximate 3-4% drop-out rate, it is intended to recruit 600 patients in total
