  1. p values refer to the significance of the difference between no rejection and rejection. The significance of the difference between healthy volunteers and no rejection is denoted by *(p < 0.05) or (p < 0.01). LV indicates left ventricle; EDV end diastolic volume; ESV end-systolic volume; SV stroke volume; EF ejection fraction, εcc peak systolic circumferential strain; SR strain rate; %AVC refers to time between peak electrocardiogram R wave and aortic valve closure expressed as a percentage. The suffix I indicates indexed to body surface area.
