Conclusion

In the EPIC-Norfolk cohort, HDL-c and apoA-I were strongly and inversely associated with CHD risk. However, these associations were not interchangeable as apoA-I levels did not show a similar trend within HDL-c quartiles, while vice versa, this was. Therefore, apoA-I levels do not offer predictive information over and above HDL-c. In contrast, an unexpected trend was even observed towards increased risk in some apoA-I quartiles. This was supported by a positive association of apoA-I levels with CHD risk factors within all HDL-c quartiles. All observations were confirmed in two independent cohorts, suggesting biological relevant associations.
