Figure 2. Kaplan-Meier curves displaying survival free from heart failure or death. A: Heart failure rehospitalizations. Frail patients experienced higher prevalence during follow-up; B: All cause mortality. Frail patients showed higher death rate than non frail patients; C: Composite end-point (death/readmission due to heart failure). Frail patients showed worse outcome.
