The myocardial mass of late gadolinium (grams) will be quantified by a semi-automatic detection method using a signal intensity threshold of >5 standard deviations above a remote reference region. Late gadolinium enhancement is revealed by MRI scanning 10 - 15 minutes after intravenous gadolinium contrast administration. Final infarct size įinal infarct size imaged on the MRI scan 6 months after initial hospitalisation for STEMI.The myocardial salvage index was defined as infarct size at 6 months indexed to the initial area-at-risk revealed by T2-weighted MRI. Myocardial salvage (% left ventricular volume) was defined as the difference between the initial jeopardised area-at-risk revealed by T2-weighted MRI (1.5 Tesla, Siemens Healthcare) at baseline and final infarct size revealed by contrast-enhanced MRI at 6 months on the same MRI scanner. Outcome Measures Primary Outcome Measures The main statistical analyses will be conducted by an independent Through central National Health Service (NHS) and government health records in order toĭetermine the long-term prognostic significance of our initial observations with angiography, Rehospitalisation, death) will be assessed at the end of the study (minimum 1 year) and againĭuring longer term follow-up (minimum 3 years, maximum 20 years) by electronic linkage Quality of life will be obtained at baseline and at 6 months post-MI. On days <12 hours, and days 2, 7-10 days and 6 months post-MI. In a subgroup of 30 patients, MRI will be performed In all patients MRI will be performed atīaseline (~day 2) and again at 6 months. Have functional and prognostic significance. We hypothesise that myocardial salvage, oedema, haemorrhage, and strain as revealed by MRI, All of this information will be linked with health outcomes in the Usual coronary wire and can provide information on heart injury, which can be linked in turn Pressure-sensitive coronary guidewire (St Jude Medical). Secondly, we will assess coronary artery disease severityīy angiography and coronary artery function at the time of the heart attack treatment using a (AAR), and the nature of this injury (strain, haemorrhage). Used to quantify the extent of myocardial jeopardy representing the initial area-at-risk

Myocardial salvage and haemorrhage are prioritised outcomes. MRI will be used to assess initial heart function and injury. Cardiac MRI scans will be performed at 1.5 Tesla Percutaneous coronary intervention (PCI). Here, we will study at least 300 consecutive patients with acute ST elevation MI (STEMI) andįocus on oedema, scar and bleeding in the heart using MRI in patients managed by emergency Recent advances in MRI have the potential to reveal new insights into the evolution andįunctional significance of myocardial injury and repair. Magnetic resonance imaging (MRI) provides detailed insights into soft tissue characteristicsĪnd this technique has particular value for imaging patients with acute myocardial infarction Other: Magnetic resonance imaging of the heart.Acute ST-elevation Myocardial Infarction.With long term being the nature of the study, most of the devices are small in size & weight to make the monitoring experience as easy as possible for the patient. Mobile Cardiac Telemetry monitors can vary slightly in size & configuration with a cellular communication device.Ĭardiac event monitors are designed to be used for long term ECG monitoring. Mobile cardiac telemetry (MCT, MCOT) monitors automatically detect and transmit real time ECG information to a diagnostic laboratory. Holter monitors are a small recording device designed to record continuous ECG information for a period of 24 hours to 14 days. Some devices are designed to capture transient symptomatic ECG arrhythmias while others are used to monitor more closely. Each type of cardiac monitoring device is designed to capture ECG information for a variety of medical conditions. Cardiac monitoring devices can range from a simple recording device to a real time monitor with cellular communication capabilities to transmit each beat. Cardiac Monitoring (AECG) devices can vary significantly in function, size & monitoring capabilities for each type of cardiac monitoring study.
