Background

Conflicting data exist regarding the superiority of non-HDL-C for the prediction of cardiovascular disease (CVD) risk, compared with LDL-C [1-5]. Therefore, there is a need to assess the predictive value of non-HDL-C for CVD and total mortality, in comparison to the predictive value of LDL-C in various populations.

In the prospective Cardiovascular Occupational Risk Factor Determination in Israel Study (CORDIS), it was evaluated whether lipid levels, including non-HDL-C, in 4,832 young, apparently healthy, male workers from 21 industrial plants have a better predictive value for total mortality and CVD mortality, compared with other lipid measures, in a long-term follow-up of 22 years, ending in 2007. The current analysis was restricted to a working population of Jewish men aged 20 to 70 years at baseline. Arab men were excluded from the current analysis.

Main results

Conclusion

In a large population of young males who were followed-up for 22 years, non-HDL-C was a more potent predictor of CVD mortality compared with LDL-C levels, after adjustment for many relevant confounding factors. These findings support existing data, according to which, non-HDL-C should be preferred over LDL-C for CV risk stratification. Interestingly, higher levels of non-HDL-C seemed to attenuate the “protective” effect of lower levels of LDL-C, although these results need to be confirmed in larger studies.
