Continuous variables are presented as mean ± SD. CMR indicates cardiovascular magnetic resonance imaging; CO, cardiac output; ESV, end-systole volume; EDV, end-diastole volume; GCS, global circumferential strain; GLS, global longitudinal strain; GRS, global radial strain; HR, heart rate; LVSD, left ventricular systolic dysfunction; LVEF, left ventricular ejection fraction; SV, stroke volume.
