Figure 5. Kaplan-Meier Estimates of Transplant and Ventricular Assist Device-Free Survival According to Cardiac Power Index and Peak VO2.

Figure 5

Subset with Peak VO2 measured, n=174. 38 deaths, 39 orthotopic heart transplants, and 8 ventricular assist device placements occurred during a median [interquartile range] follow-up of 3.12 [0.97, 4.83] years. Log-Rank, chi-square 21.6, p<0.0001 for outcomes at 3 years. Units for CPI are W/m2 and Peak VO2 ml/kg/min. Abbreviations: Peak VO2: peak-stress oxygen consumption and CPI: cardiac power index.
