Serum glucose and lipid levels in adult congenital heart disease patients

Atherosclerosis has been correlated with known cardiovascular risk factors such as serum glucose or lipid levels. Because congenital heart disease patients tend to survive until adulthood, atherosclerosis has also become a matter of concern in these patients. One hundred fifty-eight congenital heart disease patients and 152 patients selected at random from the population were studied and compared to determine serum glucose, total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein cholesterol, and triglycerides levels. Both groups had similar socioeconomic status levels and the same environmental influences. Significant differences were seen between congenital heart disease patients and the control group, after sex, age, and body mass index adjustment, in fasting plasma glucose (97.7 [94.2-101.2] vs 86.9 [83.2-90.7], P < .001), total cholesterol (171.5 [165.7-177.3] vs 199.8 [90.7-206.0], P < .001), LDL cholesterol (103.9 [98.8-108.8] vs 123.8 [118.5-129.1], P < .001), and high-density lipoprotein cholesterol (48.1 [46.2-50.0] vs 54.2 [52.1-56.2], P < .001) levels. Nonsignificant differences were seen in triglycerides concentrations. Those patients with ventricular septal defect, coarctation of the aorta, and cyanosis had the lowest total cholesterol and LDL cholesterol concentrations. Congenital heart disease patients have lower plasma cholesterol concentrations and higher serum glucose levels than noncongenital ones.
