Összefoglaló szövege

Introduction: Circulating growth differentiation factor 15 (GDF15) predicts adverse outcomes in patients with heart failure (HF). However, clinically actionable biomarkers in patients with severe HF that predict post–orthotopic heart transplantation (HTX) outcomes are scarce. Since GDF15 is a non–cardiac–specific marker of cellular stress, it might also predict post–HTX outcomes in these patients.
Aims: To characterize association between pre–HTX serum GDF15 and post–HTX outcomes in patients with end–stage HF.
Method: Using ELISA, serum GDF15 was measured in 260 healthy controls, and 343 consecutive end–stage HF patients free of mechanical circulatory support undergoing HTX. Then, these HF patients were followed for at least 1 year after HTX. The primary outcome was the association between pre–HTX GDF15 levels in patients with HF and mortality within 1 year after HTX, assessed using Cox regression analyses.
Results: End–stage HF patients had significantly higher serum GDF15 levels (median: 2032 pg/mL, interquartile range [IQR]: 1234–3978 pg/mL) compared with healthy controls (median: 215 pg/mL, IQR: 138–338 pg/mL) (p<0.001). Patients with pre–HTX serum GDF15 higher than 2550 pg/mL had significantly greater risk of death within 1 year of HTX, compared to those with lower values (hazard ratio [HR]: 3.37, 95% confidence interval [CI]: 1.94–5.86, p<0.001), even after adjusting for age, sex, body mass index, pulmonary vascular resistance, estimated glomerular filtration rate, bilirubin, and donor ischemic time (adjusted HR: 2.82, 95% CI: 1.48–5.37, p=0.002).
Conclusion: In patients with severe HF, pre–HTX GDF15 level is an independent predictor of 1–year mortality following HTX. This could inform clinical decision–making in these patients and might highlight the relevance of pharmacological interventions that alter GDF15 levels.
