Figure 1. GDF‐15 (growth differentiation factor‐15) values (pg/mL) with respect to time to decompensated heart failure admission (blue dots) or ventricular tachycardia/fibrillation (red crosses) event.

Negative numbers indicate days preceding heart failure admission date or ventricular tachycardia/fibrillation event, whereas positive numbers indicate days after the heart failure admission date or ventricular tachycardia/fibrillation event. CHF indicates congestive heart failure; GDF‐15, growth differentiation factor‐15; and VT/VF, ventricular tachycardia/fibrillation.
