The measurement of lipids currently and 9 years ago--which is more associated with carotid intima-media thickness?

Massive evidence supports that increase of lipids bring more risk of atherosclerosis. However, it is not clear if lipids measured a long time ago bear more risk than the current measurement. Lipids measured currently is more associated with carotid atherosclerosis than lipids measured long time ago. A cohort of 1195 participants age 35 to 64 years was examined in both 1993-1994 and 2002 for serum lipids, and in 2002 for carotid intima-media thickness (CIMT) with B mode ultrasound. The associations of lipids at baseline and at reexamination with CIMT were analyzed and compared using multiple linear regressions. All lipid variables, except for high-density lipoprotein cholesterol (HDL-C) both at baseline and reexamination, were significantly associated with age-adjusted CIMT in both males and females (all P(trend) <0.01). The age-adjusted mean of CIMT in all of the population was 0.696 mm in those having low low-density lipoprotein cholesterol (LDL-C) at both examinations, 0.719 mm in those having high LDL-C only at baseline, 0.706 mm in those having high LDL-C only at reexamination, and 0.727 mm in those having high LDL-C at both examinations. Further analysis showed that lipids measured at baseline remained significant, whereas lipids at reexamination became not significant in all models, except those for HDL-C and total cholesterol (TC)/HDL-C, which allow the lipids at different times to compete in association with CIMT. Both the current measurement of lipids (TC, LDL-C, non-HDL-C, TC/HDL-C, and LDL-C/HDL-C) and the measurement from 9 years ago are significantly associated with CIMT, but the measurement from 9 years ago had an even stronger association.

Predictors of anterior and posterior wall carotid intima media thickness progression in men and women at moderate risk of coronary heart disease.

The rate of carotid intima media thickness (CIMT) progression has been widely used in clinical trials as a surrogate marker for subclinical atherosclerosis. The aim of this study was to investigate relationships between coronary heart disease (CHD) risk markers and progression of CIMT in patients at moderate CHD risk. Participants included men (45-75 years) and women (55-74 years) in the control arm of a clinical trial. All had at least one major CHD risk factor and baseline posterior wall CIMT 0.7-2.0 mm, without significant stenosis. Posterior (n = 134) and anterior wall (in a subset, n = 72) CIMT were assessed with B-mode ultrasound at baseline and 12 and ∼18 months. Fasting lipoprotein lipid, apolipoprotein (Apo), inflammatory, and oxidative stress markers were evaluated. Baseline CIMT was inversely associated (P < .001) with CIMT progression. After adjustment for baseline CIMT, significant predictors of anterior wall CIMT progression in linear regression analyses included glucose (P = .044), high-density lipoprotein cholesterol (HDL-C, inverse, P = .006), triglycerides (TG, P = .006), and ratios of total cholesterol (TC)/HDL-C (P = .013), TG/HDL-C (P = .005), and Apo B/HDL-C (P = .021). Posterior wall CIMT progressed on average, whereas anterior wall CIMT regressed (0.0078 vs -0.0164 mm/year, P = .014). Significant baseline CIMT-adjusted predictors of posterior wall CIMT progression included TC (P = .028), low-density lipoprotein-C (P = .035), non-HDL-C (P = .004), TG (P = .016), Apo B (P = .005), and ratios of TC/HDL-C (P < .001), TG/HDL-C (P = .015), Apo B/Apo AI (P = .012) and Apo B/HDL-C (P = .004). The strongest predictors for CIMT progression in anterior and posterior walls were lower baseline CIMT, increased TG, and elevated ratios, including TC/HDL-C, TG/HDL-C and Apo B/HDL-C.
