Plasma apolipoproteins A-I and B in survivors of myocardial infarction and in a control group

determined in a population sample of hospital outpa-tients with a standardized method to verify if the cutpoints calculated in a cross-sectional study in the US are usable with other populations. We also tested the apolipoproteins ’ ability to discriminate between healthy people and survivors of myocardial infarction. In the studied population the apo A-I value correspond-ing to the HDL-cholesterol decisional centile is 1.12 g/L for males and 1.17 g/L for females; the apo B value corresponding to the LDL-cholesterol decisional centile is 1.23 g/L for males and 1.14 g/L for females. These values are quite close to the cutpoints proposed for the American population (1.20 g/L for both apolipopro-teins). In comparison with the LDL- and HDL-choles-terol decisional concentrations, the cutpoints for apoli
