[Study of the origin of hyperglycemia in acute myocardial infarct].
In order to clarify the origin of hyperglycaemia, blood glucose, glycated haemoglobin (GHb) and protein-corrected serum fructosamine (SFA) values were simultaneously determined at admission of 65 patients with acute myocardial infarction while oral glucose tolerance test was performed later at discharge. In 29 patients no alterations in carbohydrate metabolism were found (blood glucose: 5.2 +/- 0.1 mmol/l, GHb: 4.4 +/- 0.1%, SFA: 2.20 +/- 0.08 mmol/l) while in 9 patients diabetes was already recorded in the medical history (blood glucose: 11.5 +/- 1.1 mmol/l, GHb: 7.9 +/- 0.9%, SFA: 3.36 +/- 0.31 mmol/l, p < 0.001). Undiagnosed diabetes was documented in 8 patients (blood glucose: 11.8 +/- 1.3 mmol/l, GHb: 7.3 +/- 0.6%, SFA: 3.51 +/- 0.24 mmol/l) while stress-hyperglycaemia was found in 19 patients (blood glucose: 8.4 +/- 0.3 mmol/l, GHb: 4.5 +/- 0.1%, SFA: 2.55 +/- 0.17 mmol/l). Undiagnosed diabetes could be recorded in one seventh while stress-hyperglycaemia could be found in one third of non-diabetic patients with acute myocardial infarction. Due to overlapping values SFA is not suitable to distinguish between stress-hyperglycaemia and undiagnosed diabetes in patients with acute myocardial infarction.
