Increased non-enzymatic glycation of plasma proteins and hemoglobin in non-diabetic patients with acute myocardial infarction (MI).

BACKGROUND Glycation is known to play a key role in complications of many pathophysiological processes. The present study was carried out to assess whether there are abnormalities of non-enzymatic glycation of proteins and hemoglobin in acute Myocardial Infarction (MI) patients. METHODS Eighteen acute Myocardial Infarction (MI) patients and 20 healthy controls were enrolled for the present study. Fasting plasma glucose, fructosamine, glycated hemoglobin were evaluated. RESULTS A significant rise in the mean values of fructosamine and glycated hemoglobin was found in acute myocardial patients when compared with controls. When Pearson's correlation analysis was performed, no significant correlation was found between fasting plasma glucose with either fructosamine or glycated hemoglobin levels. CONCLUSION This data suggests an increased glycation of both plasma proteins and glycated hemoglobin in acute myocardial patients, which might be independent of prevailing glucose concentration.
