Abstract AIMS: To evaluate the association of serum concentrations of glycated apolipoprotein B (ApoBg) with the incidence of myocardial infarction (MI) in subjects with and without diabetes. METHODS: The design is a nested case-control study. The cohort included 5632 subjects over 50 years of age attending the clinical laboratories of a small geographic area in southern Italy. After five years, 4563 subjects were traced and 103 had developed MI. We sampled from the cohort two controls for each incident case of MI, frequency matched for sex and diabetes. ApoBg was measured using a monoclonal antibody. Logistic regression was used for statistical analysis of the data. RESULTS: ApoBg at baseline was higher in subjects who developed myocardial infarction than in controls in both non-diabetic and diabetic subjects (t test, P=0.009 and P=0.05 respectively). MI odds ratio in the third tertile of ApoBg was 2.01 (95\% CI 0.93-4.33) in non-diabetic and 2.88 (0.85-9.68) in diabetic subjects (chi-square test for trend; non-diabetics P=0.03, diabetics P=0.06). Serum triglycerides, cholesterol, HDL and LDL cholesterol, glucose and insulin were not associated with MI (P>0.10). CONCLUSION: ApoBg at baseline is directly associated with the development of MI in the following five years in both diabetic and non-diabetic individuals.
