BACKGROUND
Lipid oxidation and formation of oxygen radicals have been identified to be the important factors of atherogenesis. Because bilirubin, a potent physiological antioxidant inhibits lipid oxidation, it is suggested that low serum concentrations of bilirubin is associated with atherosclerosis. The aim of this study was to evaluate the relationship between bilirubin levels and coronary atherosclerosis. METHODS: The coronary calcium score (CCS) of 172 subjects (male 63, mean age 60.5 +/- 1.0) with type 2 diabetes were evaluated in Yeungnam University Hospital between January 2005 and February 2007. The subjects were divided into two groups with CCS 10 as the cut off. RESULTS: Higher CCS was significantly associated with lower bilirubin (P < 0.05), but after adjusted with age, no longer correlation were seen (P = 0.121). To determine the relationship between subclinical coronary atherosclerosis and bilirubin, the subjects with previous history of cardiovascular disease were excluded. In 138 subjects (male 54, mean age 58.4 +/- 1.1), higher CCS was significantly associated with lower levels of bilirubin. After adjusted with age, duration of diabetes, and history of hypertension, CCS was also inversely related with bilirubin (P < 0.05). CONCLUSION: These results suggest that lower levels of bilirubin might be considered as a risk factor of coronary artery disease, especially in type 2 diabetics without cardiovascular disease.

Abstract PDF: BACKGROUND
Cardiovascular disease including coronary heart disease (CHD) is the most common cause of morbidity and mortality in patients with diabetes. But traditional risk factor assessment is limited to predict CHD in asymptomatic high-risk individuals. In this study, relationship between coronary calcium score (CCS) and CHD was evaluated to determine value of coronary artery calcification detected by multi-slice spiral computed tomography to predict CHD in high risk asymptomatic patients with type 2 diabetes. METHODS: 127 patients were enrolled who admitted in Yeungnam University Hospital between December 2004 and May 2005. Standard cardiovascular risk factors and the CCS measured by multi-slice spiral computed tomography were assessed. RESULTS: Enrolled subjects were consisted of 56 subjects with diabetes and 71 subjects without diabetes. The mean CCS was significantly greater in patients with diabetes than without diabetics (P < 0.01). In both groups, patients with higher CCS had higher prevalence of CHD (P < 0.05). In all subjects, LDL cholesterol levels and CCS were significantly associated in multi-variate analysis (P < 0.05). In patients without diabetes, age was only associated with presence of CHD (P < 0.05). CCS was only associated with CHD in patients with diabetes, even after adjusting for the effects of age, LDL cholesterol and CRP (P < 0.05). CONCLUSION: Therefore, multi-slice spiral computed tomography can non-invasively and accurately detect coronary calcification. By detection of coronary artery calcification, it may be possible to predict coronary heart disease early in high-risk asymptomatic patients with type 2 diabetes.
