BACKGROUND AND PURPOSE: Echolucent carotid atherosclerotic plaques are associated with an increased risk of neurological symptoms. Elevated plasma triglycerides is a risk factor for cerebral and coronary infarction. This study examined these individual pathogenetic risk factors to determine whether they were related.
METHODS: We included 85 symptomatic patients with at least 40% carotid artery stenosis. Plaque morphology of the relevant artery was evaluated by high-resolution B-mode ultrasonography as echolucent, echo-rich, or intermediate. Fasting and postprandial lipids and lipoproteins were measured before and at hourly intervals for 4 hours after a fatty meal (1 g cream fat per kilogram body weight).
RESULTS: When we compared patients with echolucent plaques to patients with echo-rich or intermediate plaques, the former had higher fasting and postprandial plasma triglycerides (P < or = .006), higher chylomicron remnants/VLDL cholesterol (P = .02) and triglycerides (P < or = .004), a larger area under the plasma triglyceride curve 0 to 4 hours after a fatty meal, with (AUCTG-TG oh) or without (AUCTG) subtraction of fasting levels (P = .007 and P = .003), a larger body mass index (P = .03), and were younger (P = .01). Multiple logistic regression analysis found that when age and body mass index were taken into account, fasting plasma and VLDL triglycerides, postprandial chylomicron remnants/VLDL triglycerides, AUCTG-TG oh and AUCTG with odds ratios of 4.1, 3.8, 3.0, 2.7, and 4.3, respectively, were independent predictors of an echolucent plaque.
CONCLUSIONS: Echolucent carotid artery plaques are associated with elevated levels of triglyceride-rich lipoproteins in the fasting or postprandial state.
