Fig. 4

Flow pathline visualization showing different flow compartments in a control (a&b, 48yo M) and an anterior AMI patient (d&e, 66yo M). The right column shows group-averaged flow component distributions in c) controls and f) anterior AMI patients. Reported values are median ± interquartile range. Green = Direct Flow: Blood that enters the LV during diastole and leaves during systole of the same heartbeat. Yellow = Retained Inflow: Blood that enters the LV during diastole but does not leave during systole. Blue = Delayed Ejection Flow: Blood that starts inside the LV during diastole and leaves during systole. Red = Residual Volume: Blood that resides within the LV for at least two cardiac cycles
