NT-proBNP and MR-proANP were lower in obese vs. non-obese HF individuals (p = 0.013 and p = 0.01, respectively), whereas GDF-15 was similar and MR-proADM was higher in obese vs. non-obese HF individuals.
Pooled results showed that overexpression of GDF-15 was associated with poor survival in heart failure patients (log unit GDF-15: hazard ratio = 1.86, 95% CI = 1.37-2.52).
We assessed GDF-15 levels in 910 patients enrolled in the HF-ACTION (Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training) trial, a randomized clinical trial of exercise training in patients with HFrEF.Median follow-up was 30 months.
In addition to regulating body weight, MIC-1/GDF15 may be used to predict mortality and/or disease course in cancer, cardiovascular disease (CVD), chronic renal and heart failure, as well as pulmonary embolism.
