|[en] Serum alpha 1-acid glycoprotein and haptoglobin concentrations were evaluated in 151 patients with acute myocardial infarction (MI) during the first ten days of hospitalization. Maximum glycoprotein concentrations were found to be related to myoglobin and enzyme peak levels. Glycoprotein levels recorded upon patients' admission did not vary for acute phase survivors and early deaths (15 patients), but the latter demonstrated significantly higher alpha 1-acid glycoprotein levels (p less than 0.05) on day 1. The maximum glycoprotein concentrations were, however, reached too long after the onset of acute MI to be of interest for short-term prognosis. Comparison of the evolution of the two glycoproteins investigated in late deaths (10 patients) and in 6-month survivors indicated increased alpha 1-acid glycoprotein levels in non-survivors, with a maximum discrimination occurring on day 8 (p less than 0.001). Haptoglobin was not significantly different in the two groups and even demonstrated lower concentrations from day 4 to day 10 in non-survivors. The decrease of haptoglobin levels in patients with hepatic dysfunction could explain the divergent results given by the serum concentrations of the two glycoproteins to predict mortality. We show in this study that alpha 1-acid glycoprotein measured at the end of hospitalization can give relevant prognostic information for the 6-month period following acute MI.|
