Plasma sialic acid and acute-phase proteins in patients with myocardial infarction

Angiology. 1994 Aug;45(8):709-15. doi: 10.1177/000331979404500806.

Abstract

Plasma total sialic acid (TSA) and lipid-associated sialic acid (LASA) were measured in 19 patients with a myocardial infarction (MI) on days 1, 2, and 5 and in 19 normal subjects. On each day plasma TSA was elevated in the MI patients as compared with that of normal subjects, although no significant difference was seen in the plasma LASA between the two groups. The following plasma acute-phase proteins were also assayed in the MI patients and the normal subjects: C-reactive protein (CRP), alpha-1 acid glycoprotein (AGP), alpha-1 antichymotrypsin (ACT), alpha-2 macroglobulin (AMG), and fibrinogen (FIB). Significantly elevated plasma concentrations were found in the MI patients as compared with normal subjects. Furthermore, a significant correlation was found between some of these plasma acute-phase proteins (ACT, AMG, and FIB) and plasma TSA in the MI patients and also in normal subjects (ACT, AMG, CRP, and FIB). However, no significant difference was noted in any of the plasma acute-phase proteins, or plasma TSA, or plasma LASA between survivors and patients who died of their MI.
