Overzealous ventricular remodeling and molecular cardiac stress markers, including B-type natriuretic peptide (BNP), N-terminal pro-B natriuretic peptide (NT-proBNP), cardiac troponin T (cTnT), and cardiac troponin I (cTnI), are predominant compared to diastolic HF. The gene discussed is TNNI3; the disease is hydrops fetalis.
