血浆脂联素水平下降与2型糖尿病合并慢性稳定性心绞痛患者冠状动脉病变的严重性相关

目的研究血浆脂联素水平与2型糖尿病合并慢性稳定性心绞痛(DM-SAP)患者冠状动脉病变严重程度的关系。方法 236例DM-SAP患者的诊断依靠冠状动脉造影确诊,采用Gensini积分计算方法评价冠脉病变的严重程度,并根据Gensini积分四分位数分成4组,另外选取138例健康体检者作为阴性对照组。所有研究对象均采用ELISA法测定血浆脂联素水平,以免疫比浊法测定血清hs-CRP水平。结果 DM-SAP组血浆脂联素水平较阴性对照组明显降低(6.51±1.97μg/ml:7.55±1.63μg/ml,P<0.001)。较高Gensini积分四分位组(组4、3和2)的DM-SAP患者其血浆脂联素水平明显低于最低四分位组(组1)(P<0.001)。DM-SAP患者脂联素水平与当前吸烟、HbA1c水平呈显著负相关(P<0.05)。多因素Logistic回归分析显示,低脂联素水平是DM-SAP患者冠脉病变严重程度的独立危险因素(OR=17.78,95%CI 6.453～49.01,P<0.001)。结论血浆脂联素水平随着2型糖尿病合并慢性稳定性心绞痛冠脉病变的严重性显著下降,表明血浆脂联素水平下降可能参与了动脉粥样硬化的病理过程。

Relationship between Decreased Plasma Adiponectin and Severity of Coronary Artery Lesions in Patients with Type-2 DM and Chronic Stable Angina Pectoris

Objective To investigate the relationship between plasma adiponectin level and the severity of coronary artery lesions in patients with type-2 DM and chronic stable angina pectoris(DM-SAP).Methods 236 DM-SAP patients were diagnosed by coronary angiography,and the severity of coronary artery lesions was measured by Gensini score,then the DM-SAP patients were assigned into 4 groups according to the quartile of Gensini score,and a healthy control group(n=138) was established.Plasma adiponectin concentrations i...
