Additionally, FABP4 (HR 2.07, 95% CI 1.11–3.87; p-value = 0.022), but not FABP3, predicted the occurrence of the composite endpoint (CV death or rehospitalization for HF) in subjects with CHF and T2D (Table 4), but not in subjects without T2D (Supplementary Table S3). Here, FABP4 is linked to hydrops fetalis.
