Adiponectin levels in coronary artery ectasia

Etiopathogenesis of coronary artery ectasia (CAE), which is defi ned as abnormal dilatation of a segment of the coronary artery to 1.5 times of an adjacent normal coronary artery segment, is unclear. However, it is speculated that CAE develops in the atherosclerosis process through degeneration of coronary artery media layer. Our objective in this study is to compare levels of adiponectin between cases with CAE and normal coronary anatomy, and to examine whether adiponectin plays a role in CAE etiopathogenesis. The study registered a total of 66 cases, consisting of CAE cases (group 1, n = 36) and cases with normal coronary anatomy (group 2, n = 30). Taking coronary artery diameters of the control group cases as the reference, patients with abnormal segments 1.5 times larger than the adjacent segments were accepted as CAE. Serum adiponectin levels were 4.31 ± 2.02 μg/ml in group 1 and 6.73 ± 4.0 μg/ml in group 2 (P = 0.02). High-sensitivity Creactive protein was 4.8 ± 3.8 mg/l in group 1 and 3.6 ± 3.4 mg/l in group 2 (P > 0.05). There was a negative correlation between ectatic coronary artery diameter and plasma adiponectin level (P = 0.03; r = −0.339). It was known that adiponectin levels dropped in atherosclerotic heart disease. In this study we found low plasma adiponectin levels in acquired CAE, attributed to atherosclerosis. Therefore, we think that adiponectin might be playing a role in etiopathogenesis and progression of CAE. This in turn may indicate that hypo-adiponectinemia may be useful in revealing a realized risk in CAE. However, larger, randomized, multicenter studies are required to examine the role of adiponectin in the development of CAE.

血清同型半胱氨酸与冠心病的相关性研究

目的探讨冠心病患者血清同型半胱氨酸(homocysteine,Hcy)水平变化的临床意义。方法检测106例冠心病患者和50例健康对照组的血清Hcy的水平。结果冠心病患者血清Hcy水平较健康对照组明显升高(P0.01);稳定型心绞痛、不稳定型心绞痛及急性心肌梗死三组Hcy比较水平依次升高,差异有统计学意义(P0.05)。Hcy水平随着冠状动脉病变支数的增加依次升高,有显著性差异(P0.05)。结论血清Hcy水平变化与冠状动脉病变的严重程度相关,是冠状动脉病变程度的重要危险因素之一。

Associations Between Plasma Kinin B1 Receptor Levels and the Presence and Severity of Coronary Artery Disease

Aim: Kinin B1 receptor (KB1R) was shown to be up-regulated in human carotid atherosclerotic lesions. Serum KB1R levels were also reported to be high in patients with stroke. However, KB1R deficiency increased atherosclerotic lesions. Therefore, the role of KB1R in atherosclerosis remains unclear. Moreover, no study has reported blood KB1R levels in patients with coronary artery disease (CAD). Methods: We measured plasma KB1R levels in 375 patients undergoing coronary angiography. The severity of CAD was represented as the numbers of ＞50% stenotic vessels and segments and the severity score. Results: CAD was found in 197 patients, of whom 89 had 1-vessel disease (1-VD), 62 had 2-VD, and 46 had 3-VD. Plasma KB1R levels were higher in 197 patients with CAD than in 178 without CAD (median 83.3 vs. 73.7 pg/mL, p ＜0.01). A stepwise increase in KB1R levels was found depending on the number of stenotic vessels: 77.1 in 1-VD, 87.8 in 2-VD, and 88.5 pg/mL in 3-VD ( p ＜0.025). A high KB1R level (＞90.0 pg/mL) was present in 30% of patients with CAD(-), 39% of 1-VD, 50% of 2-VD, and 48% of 3-VD ( p ＜0.025). KB1R levels correlated with the number of stenotic segments and the severity score (r=0.14 and r=0.17, p ＜0.01). In multivariate analysis, KB1R levels were an independent factor associated with CAD. Odds ratio for CAD was 1.62 (95%CI=1.02-2.58) for high KB1R level ＞90.0 pg/mL. Conclusion: Plasma KB1R levels in patients with CAD were high and were associated with the presence and severity of CAD independent of atherosclerotic risk factors.
