Figure 2. Elevated levels of serum HE4 (human epididymis protein 4) were associated with a high risk of future cardiovascular events.

Kaplan‐Meier analysis for the probability of primary end point (A) and secondary end point (B) in patients with high and low HE4 levels. Primary end point: composite of all‐cause death, left ventricular assist device (LVAD) implantation, and hospitalization for heart failure events. Secondary end point: composite of all‐cause death and LVAD implantation.
