The clinical efficacy rate (CER) of Danshen decoction combined with conventional treatment (CT) in patients with HF, as well as the improvement of Danshen decoction combined with CT on CF, serological diagnostic indicators such as brain natriuretic peptide (BNP) [21], N-terminal pro-B type natriuretic peptide (NT-proBNP) and hypersensitive C-reactive protein (hs-CRP) in patients with HF were evaluated [22]. Here, CRP is linked to hydrops fetalis.
