Abstract

Background Results obtained largely from case-control studies have suggested that an elevated plasma concentration of apolipoprotein (apo) B may be considered an important risk factor for ischemic heart disease (IHD). Prospective data on the relevance of measuring apo A-I and apo B levels in the assessment of IHD risk, however, remain sparse as well as controversial. Methods and Results Plasma lipid, apo B, and apo A-I levels as well as other risk factors were evaluated at baseline in 1985 in a sample of 2155 men (45 to 76 years old) who were followed for a period of 5 years for clinical signs of IHD. Proportional-hazards analyses indicated that plasma apo B concentrations measured at entry were strongly associated with onset of IHD (relative rate, 1.4; 95% confidence interval [CI], 1.2 to 1.7), independent of covariables such as age, smoking, diabetes mellitus, and systolic blood pressure. Controlling for triglycerides, HDL cholesterol, and total/HDL cholesterol ratio did not eliminate the relationship between plasma apo B levels and IHD. The association between apo A-I and IHD was of lower magnitude (relative rate, 0.85; 95% CI, 0.7 to 1.0), and adjustment for selected plasma lipid and lipoprotein levels eliminated this association. Stepwise logistic regression analysis revealed that, among metabolic variables, apo B was the strongest correlate of IHD. Conclusions These prospective results emphasize the importance of apo B as a risk factor for IHD. Apo B may be regarded as a relevant tool in the assessment of IHD risk in men, because it may provide information that would not be obtained from the conventional lipid-lipoprotein profile.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
