Hemodynamic changes by Impella® output and RRI. (a). Cardiac Index (CI) by Impella output (IO) and RRI. (b). Cardiac output (CO) by Impella output (IO) and RRI. In patients with baseline RRI ≥ 0.8 CO showed no significant elevation from baseline 5.3 ± 1.4 L/min to 5.81 ± 1.2 L/min p = 0.06 and 6.18 ± 1.3 L/min p = 0.09, respectively. (c). Central venous oxygen saturation (cvsO2) by Impella output (IO) and RRI. (d): Systemic vascular resistance (SVR) by Impella output and RRI. In patients with baseline RRI < 0.8, SVR could be reduced significantly when increasing Impella® output by 1.0 L/min from baseline 1064 ± 558 s·cm−5 to 932 ± 483 s·cm−5 p = 0.04 (BL: baseline; ns: not significant, p ≥ 0.05; *: p < 0.05, **: p ≤ 0.01, ***: p < 0.001).
