In obese patients, plasma concentrations of the cardiac biomarkers did not differ between patients with and without HF, NT-proBNP (Estimate: 0.063; T-value 1.84; 95%CI –0.037–1.300; P = 0.064), MR-proANP (Estimate: 0.207; T = 1.32; 95%CI –0.101–0.515; P = 0.187), MR-proADM (Estimate: 0.112; T = 1.38; 95%CI –0.047–0.271; P = 0.168), Copeptin (Estimate: 0.093; T = 0.43; 95%CI –0.333–0.518; P = 0.669). This evidence concerns the gene AVP and hydrops fetalis.
