Non-LDL-related dyslipidaemia and coronary risk: a case-control study.

To assess the non-LDL-C-related dyslipidaemia risk of MI, 823 men aged 23 to 65 with a first MI were compared with 823 MI-free PROCAM controls matched for sex, age, smoking, DM, BP and LDL-C. Overall, the odds of MI in men with HDL-C < 1.15 mmol/L were 2.6 times those of men with HDL-C >or= 1.15 mmol/L, and the odds of MI in men with triglycerides >or= 1.71 mmol/L were 1.4 times those of men with lower triglycerides. If LDL-C was < 2.58 mmol/L, relative MI odds attributed to HDL-C < 1.15 mmol/L increased to 3.4, while relative odds attributed to triglycerides >or= 1.71 mmol/L increased to 2.6; men in this LDL category with HDL-C < 1.15 mmol/L and/or triglycerides >or= 1.71 mmol/L displayed an MI odds ratio of 5.0. MI risk associated with low HDL-C and/or high triglycerides is substantial, particularly if LDL-C is low.
