老年冠心病合并代谢综合征患者踝臂指数的临床研究

目的 研究老年冠心病合并代谢综合征(MS)患者踝臂指数(ABI)和冠状动脉病变的严重程度及心功能的关系.方法 经冠状动脉造影明确诊断为冠心病的老年患者140例,其中未合并MS者74例(无MS组),合并MS者66例(Ms组),评估两组冠状动脉病变情况,测定其ABI及心功能.结果 MS组ABI为0.90±0.32,无MS组为1.03±0.26,两组比较差异有统计学意义(P=0.015).MS组ABI≤0.9者比率高于无MS组[43.9%(29/66)比27.0%(20/74)],差异有统计学意义(P=0.038).在MS组中,ABI≤0.9者冠状动脉3支病变发生率显著高于ABI>0.9者[86.3%(25/29)比37.8%(14/37),P=0.000];ABI≤0.9者心功能降低更显著(P<0.05).结论 老年冠心病合并MS患者,其ABI较低,冠状动脉病变程度更加严重,心功能降低更加明显,应进行强化治疗.

Clinical research of the ankle-brachial index in the elderly patients with coronary heart disease with metabolism syndrome

Objective To investigate the relationship between the ankle-brachial index (ABI)and the extent of coronary artery stenosis and the left ventricular function in elderly patients with coronary heart disease (CHD)with metabolism syndrome (MS). Methods A total of 140 patients with coronary artery disease was study subjects. In which, 66 cases complicated MS (MS group), 74 cases without MS (non MS group). ABI and the left ventricular function was examined in an patients. Results ABI was 0.90±0.32 in MS group, and 1.03±0.26 in non MS group, there was significant difference between two groups(P=0.015). Compared with non MS group, significant lower ratio of ABI in MS group [43.9%(29/66) vs 27.0%(20/74)] (P=0.038); whereas much more 3-vessel disease in ABI≤0.9 patients compared with those of ABI > 0.9 patients [86.3%(25/29) vs 37.8%(14/37) ], significant lower of the left ventricular function in ABI≤0.9 patients compared with those of ABI >0.9 patients (P<0.05). Conclusion There is more severe of coronary artery stenosis in ABI≤0.9 patients for CHD with MS, more attention should be payed to CHD patients combined with MS.
