Authors' conclusion

In patients with advanced HFrEF, elevated circulating GDF-15 levels are associated with a higher prevalence of anorexia and cachexia, right ventricular dysfunction, and congestion, as well as an independently increased risk of adverse events.

Study context

Population
Patients with advanced heart failure with reduced ejection fraction (HFrEF) (age 58 ± 10 years, 85% male, 67% NYHA class III)
Participants
344 patients
Exposure
Higher vs lower GDF-15 levels
Outcome
Combined endpoint of death, urgent transplantation or LV assist device implantation

Main finding

As reported in the abstract

Death, urgent transplantation or LV assist device implantation

Hazard ratio

2.31

95% CI 1.47–3.66

P < 0.001

T3 vs T1
HR 2.31 (95% CI 1.47–3.66); P < 0.001

Observational data: associations, not effects.

Further findings

GDF-15 level

Median GDF-15 (Q1-Q3: 955-2,332 ng/L; reference range <1,200 ng/L)
1,503 ng/L

Anorexia and cachexia

Higher GDF-15 associated with more prevalent anorexia and cachexia

Circulating metabolites

Higher GDF-15: increased free fatty acids and beta-hydroxybutyrate, lower albumin, cholesterol and insulin/glucagon ratio, consistent with a catabolic state

Congestion and RV function

Higher GDF-15: worse congestion and more severe RV dysfunction
