Abstract:
Introduction: Growth differentiation factor-15 (GDF-15), a stress-responsive member of the transforming growth factor ꞵ cytokine superfamily is an independent prognostic predictor in patients with heart failure (HF). GDF-15 has been also reported to be associated with cardiac cachexia and malnutrition. However the association of GDF-15 and prognosis in patients with HF according to body mass index (BMI) is unclear. Methods: The PREHOSP-CHF study is a multicenter prospective cohort study among patients with HF. A total of 1,024 patients (mean age, 75.5 years, 58.7% male) were included in the analyses. Serum levels of GDF-15, as well as N-terminal pro brain natriuretic peptide (NT-proBNP), high sensitivity troponin I (hs-cTnI), and high sensitivity C-reactive protein (hs-CRP), were measured. We divided the patients into 3 groups based on the tertile of BMI: low (≤19.9), middle (19.9 〈 , ≤23.4), and high ( 〉 23.4). Results: The low BMI group were older, and had more female, HF with preserved ejection fraction (≥50%), and NYHA 3/4. NT-proBNP levels were higher in the low group, but hs-cTnI and hs-CRP were comparable between the 3 subgroups. Median GDF-15 levels in the low, middle and high groups were 2271, 2264, and 1888 pg/ml, respectively. During 2 years follow-up, all-cause death and major adverse cardiovascular events (MACE: cardiovascular death and HF hospitalization) occurred in 111 and 130 in the low group, 66 and 132 in the middle group, and 34 and 88 in the high group. After adjustment for clinical confounders and cardiac biomarkers, higher GDF-15 was significantly associated with the incidence of all-caused death and MACE in the entire cohort. BMI subgroup analysis revealed that higher GDF-15 was significantly associated with the incidence of all-caused death and MACE in the middle and high groups, but not in the low group (Figure). Conclusions: Among HF, higher GDF-15 was significantly associated with all-cause death and MACE especially in the middle and high BMI groups.
