Objective-The Apolipoprotein-related Mortality Risk (AMORIS) study concluded that the apolipoprotein (apo)B/apoA-I ratio was the best predictor of coronary heart disease (CHD) risk. We have compared the pairwise combinations of total cholesterol, triglycerides (TGs), apoB, high density lipoprotein (HDL) cholesterol, low density lipoprotein cholesterol, and apoA-I on CHD risk prediction in middle-aged men. Methods and Results-Healthy middle-aged men (nϭ2508), free of CHD at baseline, were

The relative risk (RR) of CHD associated with cholesterol, TGs, apoB, apoA-I, apoB/apoA-I, low density lipoprotein cholesterol, and HDL cholesterol were examined by survival analysis. The apoB/apoA-I ratio was associated with the strongest effect on the RR (3.58, 95% CI 2.08 to 6.19). In multivariate analysis, apoA-I had no significant effect on risk. Examining RR by quartiles, apoB and HDL in combination (RR 8.38, 95% CI 3.21 to 21.92) were better predictors of CHD risk than apoB and TGs (RR 4.05, 95% CI 1.57 to 6.23). However, apoB and TGs in combination added risk information over and above lifestyle factors, whereas apoB and HDL cholesterol did not. Conclusions-The combined evaluation of apoB with TGs provides useful diagnostic criteria for CHD risk. (Arterioscler Thromb Vasc Biol. 2002;22:1918-1923.)
