Changes of acute phase proteins glycosylation profile as a possible prognostic marker in myocardial infarction

Abstract

In 24 consecutive patients with myocardial infarction, the concentrations of C-reactive protein, α 1-acid glycoprotein and α 1-antichymotrypsin, as well as acid α 1-glycoprotein and α 1-antichymotrypsin glycosylation profiles were estimated. Blood samples were taken at admission, after 4, 8, 12 and 24 h, on 2, 3, 6, 9, and 12 days of hospitalization. All studied patients were divided into 2 groups: 12 patients without clinical or radiological symptoms of acute heart failure and 12 patients with acute heart failure. The results of all investigations were tested statistically to appraise significance of differences between the two investigated groups. At admission, as well as after 6 and 12 h, C-reactive protein concentration was significantly higher in patients who developed heart failure. Similarly, the glycosylation profile of α 1-antichymotrypsin, reported as reactivity coefficient, was of good prognostic value from the first time-point on. Development of acute cardiac failure seemed to correlate more with the magnitude of inflammatory reaction (measured by changes in acute phase proteins) than with enzymatically estimated infarct size.
