目的:探讨踝臂指数(ABI)与冠状动脉(冠脉)病变程度的关系。方法:对纳入研究的192例患者收集其基线资料、测量ABI、行冠脉造影,ABI<0.9者为研究组(56例),ABI≥0.9者为对照组(136例,应用多变量Logistic回归分析2组ABI与冠心病危险因子及冠脉病变程度的相关性。结果:2组的病变血管支数,3支病变、B2/C型复杂病变例数比较,差异均有统计学意义(P<0.01);多个心血管危险因子与ABI<0.9存在相关性,ABI<0.9是冠脉3支病变及B2/C型复杂病变的独立预测因子(OR值分别为3.839、3.001)。结论:ABI<0.9一定程度上能够预测冠脉复杂病变(3支病变及B2/C型复杂病变)。
Objective: To investigate the relationship between the ankle-brachial index (ABI) and the degree of coronary artery (coronary artery) lesion. METHODS: A total of 192 patients enrolled in the study were enrolled in this study. Baseline data were collected and ABI and coronary angiography were performed. ABI <0.9 in the study group (56 cases) and ABI ≥ 0.9 in the control group (136 cases. Multivariate Logistic regression The correlation between ABI and risk factors of coronary heart disease and coronary artery disease were analyzed.Results: There were significant differences in the number of vascular lesions, 3 lesions and complicated type B2 / C lesions between the two groups (P <0.01) .Among multiple cardiovascular risk factors and ABI <0.9, ABI <0.9 was an independent predictor of 3 lesions of coronary artery and complex type B2 / C (OR = 3.839 and 3.001 respectively) .Conclusion: ABI <0.9 to some extent able to predict the complex coronary lesions (3 lesions and B2 / C complex lesions).
