Echocardiographic images were taken by certified sonographers, within the first 72-hours from the time of PCI, prior to the hospital discharge. The LV dimensions and volumetric measurements were done in the standard transthoracic views. The Synapse Cardiovascular (FujiFilm, Valhalla, NY, USA) Software was used to postprocess and interpret the echocardiograms.
Cardiac MRI was acquired within 72 hours after echocardiography acquisition. A GE 1.5-T scanner with technical parameters recommended by the manufacturer was used. Scout images in coronal, sagittal and axial planes; fast spin-echo (FSE) axial slices; short-axis and two, three, and four-chamber steady-state free precession (SSFP) sequences; T2-weighted triple-inversion recovery images; T1-weighted FSE sequence, and delayed enhanced images 7–10 minutes after gadolinium (Omniscan 0.1 mmol/kg) injection were acquired. LV dimensions and measurements were performed by using Segment version 3.2 R8531 (http://segment.heiberg.se ), as described previously by our group (18 (link)).
