Cine CMR diastolic function parameters in acute ST-elevation MI (STEMI) patients are associated with cardiac injury and left ventricular strain

Background Presence of diastolic dysfunction in patients with history of myocardial infarction represents a marker of adverse outcomes. However, its role in acute ST-elevation myocardial infarction (STEMI) is not fully elucidated. Cardiovascular magnetic resonance (CMR) allows quantitative measurement of volumetric changes that occur during diastole and form basis for calculation of different parameters of diastolic function. The relationships between these parameters, LV systolic function and strain, and markers of cardiac injury in STEMI are unknown.
