    Diabetes is associated with increased mortality following acute myocardial infarction compared to the general population. Elevated glycated haemoglobin (HbA1c) in diabetic patients is also associated with increased mortality following acute myocardial infarction, while mild elevation in HbA1c are associated with impaired glucose tolerance. The aim of this study was to determine the influence of HbA1c on outcome of acute myocardial infarction in 253 non-diabetic patients, 46 of whom died in one year. In univariate analysis, risk factors for death included smoking, glucose, cholesterol and HbA1c. In logistic regression analysis HbA1c was an independent risk factor for death. Over one-third of the fatality group had an HbA1c in the highest quartile, compared to one-fifth of the surviving group (p = 0.02). Elevated HbA1c is a risk marker for short-term mortality following acute myocardial infarction in non-diabetic subjects.
