CMR Repeatability in STEMI

October 27, 2014 updated by: Elisa McAlindon, University of Bristol

Cardiovascular Magnetic Resonance Scan Repeatability in ST Segment Elevation Myocardial Infarction

The investigators propose to conduct a study to measure the reproducibility of CMR parameters that have been used to predict outcome following PPCI: infarct size, left ventricular volumes, myocardial salvage, microvascular obstruction (MVO) and myocardial oedema.
