It may be because serum NT-proBNP levels at first admission can indicate only a short congestive state (51), and there are several novel mechanisms between HDL-C level and left ventricular reverse remodeling in patients with DCM; in our study, there are obvious differences in the HDL-C level but not in hsCRP and NT-proBNP between the LVRR and non-LVRR groups. Here, NPPB is linked to familial dilated cardiomyopathy.
