Receiver-operating characteristic (ROC) analysis between AL-CA patients with impaired LV systolic function and normal controls. The use of cut-off values of upslope (Green), TTM (Blue) and MaxSI (Red) could discriminate the microcirculation of AL-CA patients with impaired LV systolic function from that of normal controls in the basal (a), mid-ventricular (b) and apex (c) segments
