The aim of our study was to compare apolipoprotein B (apoB), non-high density lipoprotein cholesterol (nonHDL-C), low density lipoprotein cholesterol (LDL-C), and other lipid markers as predictors of coronary heart disease (CHD) in Chinese. Overall, 122 individuals developed CHD during a median 13.6 years of follow-up in 3,568 adult participants from a community-based cohort. The multivariate relative risk of CHD in the highest quintile compared with the lowest quintile was 2.74 [95% confidence interval (CI), 1.45–5.19] for apoB, 1.98 (95% CI, 1.00–3.92) for nonHDL-C, and 1.86 (95% CI, 1.00–3.49) for LDL-C (all tests for trend, P < 0.05). ApoB also had the highest receiver operator characteristic curve area (0.63; 95% CI, 0.58–0.68) in predicting CHD. When apoB and nonHDL-C were mutually adjusted, only apoB was predictive; the relative risk was 2.80 (95% CI, 1.31–5.96; P = 0.001) compared with 1.09 (95% CI, 0.49–2.40; P = 0.75) for nonHDL-C. Compared with the lowest risk, participants with the highest apoB and total cholesterol/HDL-C had a 3-fold increased risk of developing CHD (relative risk = 3.21; 95% CI, 1.45–7.14). These data provide strong evidence that apoB concentration was a better predictor of CHD than other lipid markers in Chinese.
