title: Differences between markers of atherogenic lipoproteins in predicting high cardiovascular risk and subclinical atherosclerosis in asymptomatic men.
abstract: OBJECTIVE
  As main markers of atherogenic lipoproteins, apolipoprotein B (apoB), non-HDL cholesterol (non-HDLC), and LDL cholesterol (LDLC) do not seem equipotent to predict cardiovascular complications, we have compared simultaneously their capacity to predict high cardiovascular risk and subclinical atherosclerosis in a primary prevention population.
  
  
  METHODS
  In 723 asymptomatic men, we measured apoB, non-HDLC, and LDLC, and we determined concomitantly coronary heart disease (CHD) risk equivalent defined by National Cholesterol Education Program guidelines, ultrasound-assessed extra-coronary plaques at multiple sites, and electron beam computed tomography-assessed high coronary calcium.
  
  
  RESULTS
  Odds ratios (95% confidence interval) per standard deviation of apoB, non-HDLC, and LDLC of having: (i) CHD risk equivalent were 1.90 (1.53-2.37), 1.78 (1.43-2.21), 1.47 (1.19-1.81); (ii) extra-coronary plaques were 1.37 (1.16-1.61), 1.31 (1.11-1.56), 1.19 (1.01-1.39); (iii) high coronary calcium were 1.35 (1.09-1.68), 1.33 (1.07-1.64), 1.26 (1.01-1.39), respectively. Risk factors and treatment did not confound the above associations, except triglycerides for which adjustment weakened the risk predictions of lipids and annihilated lipids differences in predicting CHD risk equivalent and atherosclerosis markers.
  
  
  CONCLUSIONS
  ApoB was the best predictor, non-HDLC the second best predictor, and LDLC the poorest predictor of high cardiovascular risk and subclinical extra-coronary and coronary atherosclerosis, and triglycerides participated to these differences.
