CMR imaging protocol and analysis
EVENT
Within 10 days after the index event an identical CMR protocol was applied in all patients. The protocol was performed on 1.5 or 3 T CMR scanners at the respective study sites including balanced steady-state free precession sequences (bSSFP) of long-axis 2- and 4-chamber views as well as short axis (SAx) stacks. Typical bSSFP sequence parameters were as follows: TR 3.2 ms, TE 1.2 ms, flip angle 60°, 8 mm slice thickness in SAx. More detailed information on CMR scan protocols have been published previously [
