HF patients showed higher plasma levels of MPO-related chlorinating activity, Cp, BNP, norepinephrine, hsCRP, free MAD, nitrated protein, and 15-F2t-isoprostane as compared to CTR subjects, whereas FeOxI activity, albumin, and prealbumin were significantly reduced in HF versus CTR subjects (Table 2).
