Figure 1 The Seattle Heart Failure Score (SHFS) for patients in the original Seattle Heart Failure Model cohort are rounded to the closest integer from 0 to 4 and stratified by NYHA class. Within each NYHA class, the SHFS provided additional risk stratification. For any given SHFS, the risk of death was similar for NYHA Class II, III or IV heart failure patients. The percent of patients with SHFS 3 or 4 (>40% annual mortality) is shown for each NYHA class.

Figure 3 Kaplan–Meier survival curve with the Seattle Heart Failure Score assuming medical management is rounded to the nearest integer from 3 to 5. (a) Survival in the medical group. (b) Survival in the LVAD group, which improved.
