To determine whether an increased familial risk for coronary artery disease in young adult men is related to changes in postprandial lipoprotein metabolism.
Coronary angiography departments of four central general hospitals in the Netherlands.
80 sons (mean age, 24.8 years) of men with severe coronary artery disease and 55 sons (mean age, 23.2 years) of controls.
Postprandial levels of serum triglycerides, retinyl palmitate, and total cholesterol were measured during a 12-hour period after a standardized oral lipid load.
Both groups showed a marked increase in levels of serum triglyceride and retinyl palmitate after lipid loading, reaching a maximum 4 to 6 hours postprandially. No changes in postprandial total cholesterol levels were observed in either group. Sons of men with coronary artery disease had prolonged postprandial hypertriglyceridemia when compared with sons of controls. Significant differences in postprandial triglyceride levels were found at 8 hours (difference, 0.35 mmol/L; 95% CI, 0.07 to 0.62 mmol/L), at 10 hours (difference, 0.21 mmol/L; CI, 0.06 to 0.36 mmol/L), and at 12 hours after lipid loading (difference, 0.13 mmol/L; CI, 0.01 to 0.26 mmol/L). Levels of postprandial retinyl palmitate were also slightly, but not statistically, different (mainly after 6 hours).
Healthy young adult sons, whose fathers have established coronary artery disease, have prolonged postprandial hypertriglyceridemia. Changes in postprandial lipoprotein metabolism appear to be associated with familial risk for coronary atherosclerosis.
