Prognostic value of apolipoprotein B and A-I in the prediction of myocardial infarction in middle-aged men and women: results from the MONICA/KORA Augsburg cohort study.

To investigate the association between apolipoprotein B (apoB), A-I (apoA-I), the apoB/apoA-I ratio, and the incidence of coronary events.


Analysis included 1414 men and 1436 women aged 35-64 years without a prior coronary event who participated in the population-based MONICA Augsburg survey 1984-85 (median followed-up period 13 years). Incidence of fatal and non-fatal myocardial infarction, and sudden cardiac death was assessed using data of the MONICA/KORA Augsburg coronary event registry. During follow-up, 114 incident coronary events occurred in men and 31 in women. In multivariable analysis, an increase of 1 standard deviation in the serum concentration of apoB was associated with an increased risk of coronary events in men [hazard ratio (HR)=1.49; 95% confidence interval (CI); 1.25-1.78] and in women (HR=1.73; 95% CI; 1.32-2.27). By contrast, elevated concentrations of apoA-I were not associated with a significantly decreased risk of coronary events in either sex (HR=0.91). Furthermore, the predictive power of the apoB/apoA-I ratio was similar to that of the total cholesterol/HDL cholesterol ratio in men and women.


ApoB and the apoB/apoA-I ratio were strong predictors of coronary events in middle-aged men and women, whereas apoA-I did not add significantly to the estimation of future coronary risk.
