The role of left ventricular deformation in the assessment of microvascular obstruction and intramyocardial haemorrhage
Why the study?
Does global longitudinal strain (GLS) measured by CMR correlate with microvascular obstruction, intramyocardial haemorrhage, and adverse LV remodelling in patients with reperfused STEMI?
Population
43 patients with reperfused STEMI and 10 age and gender matched healthy controls

Overview
Baseline global longitudinal strain measured by CMR is strongly associated with microvascular obstruction, intramyocardial haemorrhage, and subsequent adverse LV remodelling in patients with reperfused STEMI.
