Figure 1 Kaplan-Meier plot of survival without left ventricular assist device or transplant for 173 patients on angiotensin-converting enzyme inhibitors (ACEI), 45 patients with circulatory-renal limitations (CRLimit) not on intravenous (IV) inotropes, and 14 patients with CRLimit on IV inotropes. Patients on angiotensin-converting enzyme inhibitors had significantly longer survival time than patients with CRLimit (p < 0.0001). CRLimit patients who did not receive IV inotropes had significantly longer survival times than CRLimit patients who received IV inotropes (p = 0.002). The numbers of patients remaining at three-month intervals up to 24 months are noted on the plot.
