冠心病合并代谢综合征患者踝臂指数与冠脉病变程度的关系

目的：研究合并代谢综合征（MS）冠心病患者MS与踝臂指数和冠脉病变的严重程度的关系。方法：连续人选经冠状动脉造影明确诊断为冠心病的老年患者．评估冠脉病变情况，测定其踝臂指数（ABI），根据是否存在MS及ABI正常与否进行分组。分析单独及联合MS、ABI≤0．90预测冠心病冠脉病变程度的状况。结果：共人选151例冠心病患者，其中合并MS者64例，无MS者87例。相对于无MS组，MS组的低ABI（≤0．9）比例明显增高（43．8％：27．6％．P=0．039）；ABI值更低（0．91±0．31）：（1．02±0．25），P=0．016；低ABI者三支病变显著增多（60．9％：32．2％．P=0．000）．而单支病变明显较少（18．8％：42．5%，P=0．002）。结论：冠心病患者如合并代谢综合征．则ABI值更低．冠状动脉病变更加严重，应进行强化治疗。

Relationship between abnormal ankle brachial index and extent of coronary artery stenosis in aged coronary artery disease patients with metabolism syndrome

Objective： To study the relationship between abnormal ankle brachial index （ABI） and extent of coronary artery stenosis in aged coronary artery disease patients with metabolism syndrome. Methods： A total of 151 patients with coronary artery disease were study subjects. In which, 64 cases complicated MS, 87 cases without MS. ABI was examined in all patients. Results： Compared with non MS group, a significant lower ratio of ABI （43.8% ： 27.6%, P=0.039）, lower ABI （0.91±0.31） ： （1.02±0.25）, P=0.016] in MS group; whereas much more 3-- vessel disease （60.9%： 32.2%, P=0. 000）, a fewer single-vessel disease in ABI≤0.90 group compared with those of ABI normal group （18.8% ： 42.5%, P=0. 002）. Conclusion： There is more severe of coronary artery stenosis in ABI≤ 0.90 patients for CAD patients with metabolic syndrome, should pay more attention to CAD patients combined with MS and ABI≤0.90.
