Levels of soluble E-selectin and ICAM-1 in the coronary circulation of patients with stable coronary artery disease: association with the severity of coronary atherosclerosis

The recruitment of circulating leukocytes to atherosclerotic sites is mediated by a family of adhesion molecules. The objective of the present study was to evaluate the relationship between circulating adhesion molecule levels in the coronary circulation and the severity of coronary atherosclerosis in patients with stable coronary artery disease. The subjects were 79 patients undergoing coronary angiography. According to the severity of coronary atherosclerosis as assessed by the Gensini Score (GS) of the left coronary artery, they were classified into three groups: group C (no organic stenosis, score 0, n = 14), group M (mild organic stenosis, score 1-13, n = 39) and group S (severe organic stenosis, score > or = 14, n = 26). Blood samples were taken from the aorta (Ao) and coronary sinus (CS), and plasma levels of soluble E-selectin (sE-selectin) and soluble intercellular adhesion molecule-1 (sICAM-1) were measured by enzyme-linked immunosorbent assay. These levels were then compared between groups. There were no significant differences in plasma sICAM-1 levels in the Ao or CS between the three groups. The difference in sICAM-1 levels between the CS and Ao (CS-Ao) also showed no significant difference. Plasma sE-selectin levels in both the Ao and CS were significantly higher in group S than in groups C and M (p < 0.05), but there were no significant differences in CS-Ao. There was a weak but significant correlation between the plasma levels of these adhesion molecules and the number of coronary risk factors present. Multivariate analysis showed that the number of coronary risk factors was the only positive predictor (p = 0.0048) of the GS; there was no association between the plasma level of either adhesion molecule and the GS. In patients with stable coronary artery disease, sICAM-1 plasma levels do not indicate the severity of coronary atherosclerosis, while sE-selectin plasma levels appear to reflect the severity of systemic rather than coronary atherosclerosis.     

老年冠心病患者血尿酸水平与冠状动脉病变程度的相关性

目的探讨老年冠心病患者血尿酸水平与冠状动脉病变范围及狭窄程度的关系。方法选取289例经冠状动脉造影确诊冠心病（管腔狭窄≥50％）的70岁以上老年冠心病患者。采用Gensini积分评价冠状动脉病变严重程度。术前检查血尿酸水平。对比分析患者血尿酸水平与冠状动脉狭窄程度及范围的关系。结果289例患者中单支病变组、双支病变组和多支病变组患者的血尿酸水平差异无统计学意义[（0．358±0．102）w（0．379±0．112）VS（0．366±0．112），P〉O．05]，不同Gensini积分组患者的血尿酸水平差异无统计学意义[（0．360±0．100）坩（0．375±0．119）w（0．369±0．100）w（0．370±0．123），P〉0．05]，尿酸正常组与高尿酸血症组患者的Gensini积分差异无统计学意义[（37．138±24．934）w（41．887±35．294），P〉0．05]。单独分析男性患者和女性患者，单支病变组、双支病变组和多支病变组的血尿酸水平差异均无统计学意义，不同Gensini积分组患者的血尿酸水平差异无统计学意义。结论目前尚缺乏证据证明血尿酸水平可以作为老年冠心病患者冠状动脉病变严重程度的危险因素或预测因子。     

Significance of soluble thrombomodulin in the coronary circulation of patients with coronary artery disease

OBJECTIVES: The relationship between plasma levels of soluble thrombomodulin, a probable marker for endothelial damage, and the severity of coronary atherosclerosis was investigated. METHODS: Plasma soluble thrombomodulin levels were evaluated in 160 patients(mean age 62 +/- 11 years) who underwent coronary angiography. Blood samples were obtained from the peripheral vein, ostium of the left coronary artery and coronary sinus. The levels of plasma thrombomodulin were measured by enzyme-linked immunosorbent assay. The change of thrombomodulin level in the coronary circulation (delta TM) was calculated as the coronary sino-arterial difference. Patients were classified into four groups according to the number of diseased vessels, and the severity of coronary atherosclerosis was evaluated with the modified Gensini score. RESULTS: Coronary sinus levels of thrombomodulin were significantly higher in the two or more vessel disease(VD) groups than in the no or one VD groups(p < 0.05). delta TM were significantly higher in the 2VD than in the 0VD groups(p < 0.05), and higher in the 3VD than in the 0VD or 1VD groups(p < 0.05). delta TM showed positive correlation with Gensini score for left coronary arteries(r = 0.347, p < 0.0001). CONCLUSIONS: The increment of thrombomodulin across the coronary circulation was significantly correlated with the severity of coronary atherosclerosis, suggesting a close association between the progression of coronary atherosclerotic stenosis and damage to the endothelial surface.

Reduced adiponectin level is associated with severity of coronary artery disease

Adipocyte-derived adiponectin has an antiatherosclerotic effect that acts independently of its antidiabetic effect. Plasma adiponectin levels are generally low in subjects with coronary artery disease. In this study, the relationship between the plasma adiponectin level and the severity of coronary artery disease, as assessed using the Gensini score, an index for the severity of coronary artery stenosis, was investigated. The subjects of the study were 104 patients (72 men and 32 women; BMI, 23.5 +/- 3.3 kg/m(2); age, 63.6 +/- 10.1 years) admitted to Tokyo University Hospital for coronary angiography. Plasma adiponectin levels were inversely correlated with the insulin resistance index HOMA-IR (P = 0.0127). The plasma adiponectin level was significantly associated with the Gensini score (P = 0.0332). After adjustment for conventional risk factors for cardiovascular diseases, the plasma adiponectin level tended to be inversely correlated with the Gensini score (P = 0.087). The measurement of plasma adiponectin levels may be useful for predicting the severity of coronary artery stenosis.     

Decreased plasma urotensin Ⅱ levels inversely correlate with extent and severity of coronary artery disease

Objective To determine the plasma urolensin Ⅱ(UII) levels in various types of coronary heart disease and to clarify how the plasma UII levels correlate with the clinical presentation, extent and severity of coronary artery atherosclerosis (CAD). Methods: One hundred and three aged patients undergoing elective diagnostic coronary angiography for proven or clinical suspected coronary heart disease were enrolled in this study. The extent and severity of coronary artery disease were evaluated by vessel score and Gensini score, respectively. Plasma UII levels were measured by radioimmunoassay. Results: The plasma UII levels in the patients with modest to severe coronary stenosis (3.03±0.34 pg/ml, 1.83±0.67 pg/ml) were significantly lower than that in subjects with normal coronary artery (4.80±1.11 pg/ml, P<0.001). The plasma UII levels in patients with coronary heart disease were also significantly lower than that in patients with insignificant coronary stenosis (P < 0. 001). Compared to patients with stable angina pectoris, plasma UII levels in patients with acute coronary syndrome were significantly decreased (1.89±0.51 pg/ml vs 2.42±0.77 pg/ml, P < 0.001). Plasma UII levels were found to be negatively correlated with the severity of coronary artery stenosis (r = -0.488, P<0.001), as well as the vessel score (r = -0.408, P<0.05) in the patients with CAD. Conclusion: Significant inverse correlations exist between the plasma UII levels, and the extent and severity of coronary artery stenosis. These findings suggest that plasma UII contribute to the development and progression of coronary artery stenosis, and may be a novel marker to predict clinical types, as well as the extent and severity of coronary artery disease in the patients.

The extent and severity of coronary artery disease were evaluated by vessel score and Gensini score, respectively. Plasma UⅡ levels were measured by radioimmunoassay. Results: The plasma UⅡ levels in the patients with modest to severe coronary stenosis (3.03±0.34 pg/ml, 1.83±0.67 pg/ml) were significantly lower than that in subjects with normal coronary artery (4.80±1.11 pg/ml, P＜0.001). The plasma UⅡ levels in patients with coronary heart disease were also significantly lower than that in patients with insignificant coronary stenosis (P ＜ 0.001). Compared to patients with stable angina pectoris, plasma UⅡ levels in patients with acute coronary syndrome were significantly decreased (1.89±0.51 pg/ml vs 2.42±0.77 pg/ml, P＜ 0.001). Plasma UⅡ levels were found to be negatively correlated with the severity of coronary artery stenosis (r = -0.488, P＜0.001), as well as the vessel score (r = -0.408, P＜0.05) in the patients with CAD. Conclusion: Significant inverse correlations exist between the plasma UⅡ levels, and the extent and severity of coronary artery stenosis. These findings suggest that plasma UⅡ contribute to the development and progression of coronary artery stenosis, and may be a novel marker to predict clinical types, as well as the extent and severity of coronary artery disease in the patients.
