BACKGROUND: Although the total to high-density lipoprotein cholesterol ratio (TC/HDL-C) has been used for decades to identify individuals at risk for coronary heart disease (CHD), apolipoprotein-based (apolipoprotein B/apolipoprotein A-I [apoB/apoA-I]) and nuclear magnetic resonance spectroscopy (NMR)-based lipoprotein concentrations (low-density lipoprotein(NMR) /high-density lipoprotein(NMR) [LDL(NMR) /HDL(NMR)]) may also be useful for CHD risk stratification. MATERIALS AND METHODS: In a case-control study conducted within the European Prospective Investigation into Cancer and Nutrition (EPIC)-Norfolk study population, 870 individuals who developed CHD during a 6-year follow-up were matched to 1659 controls on the basis of gender, age and enrollment time. LDL(NMR) and HDL(NMR) were measured by proton NMR spectroscopy. RESULTS: After adjusting for traditional CHD risk factors, men in the top quintile of the various lipoprotein ratios proved to be at increased CHD risk (OR = 2·59 [95% IC, 1·76-3·83] for TC/HDL-C ratio, 2·59 [1·75-3·83] for apoB/apoA-I ratio and 2·78 [1·86-4·17] for LDL(NMR) /HDL(NMR) ratio) compared with men in the bottom quintile. Similar associations were observed in women (OR = 2·86 [1·71-4·80] for TC/HDL-C ratio, 2·94 [1·74-4·97] for apoB/apoA-I ratio and 2·03 [1·21-3·43] for LDL(NMR)/HDL(NMR) ratio). Compared with participants with only one component of the metabolic syndrome, those who had five had an increased TC/HDL-C ratio (73·0% and 80·4% in men and women respectively), apoB/apoA-I ratio (58·0% and 62·9% in men and women respectively) and for LDL(NMR)/HDL(NMR) ratio (52·6% and 54·1% in men and women respectively). CONCLUSION: In this European study population, the TC/HDL-C, apoB/apoA-I and LDL(NMR) /HDL(NMR) ratios were similarly associated with components of the metabolic syndrome and CHD risk.
