Based on logistic regression analysis, ROC analysis demonstrated that HSPH1 (AUC = 0.814, P = 0.005) and VEGFA (AUC = 0.814, P = 0.005) had high accuracy in diagnosing chronic DCM-induced HF, especially HSPH1 combined with VEGFA (AUC = 0.898, P = 0.000) (Figures 11B–D). Here, VEGFA is linked to hydrops fetalis.
