Abstract

Objective

this study was designed to better understand the evolution of the ankle brachial Index (ABI) over time, so as to better inform clinical decision-making.

Methods

patient selection included consecutive patients with at least two documented ABI Indexes obtained at Emory Healthcare between April 2005 and April 2013. Retrospective chart reviews were conducted on consecutive patients to assess ABI Index values, time between ABIs and whether revascularization had occurred between the two ABI measures. Qualifying patients included 76 patients with two ABIs and without a surgical intervention between the two measures.

Results

the primary study outcome measure was the change in ABI per day. The average change in ABI per year was calculated as -0.012045. Extrapolating from these data, the estimated time in which meaningful deterioration (0.1) was found to be 8.3 years.

Conclusion

these data demonstrate a change in ABI that is minimal and thus suggest that without intervening medical treatments that would change the ABI, routinely repeating this test is not warranted.

踝肱指数随时间的变化

目的本研究旨在更好地了解踝肱指数(ankle brachial Index, ABI)随时间的演变，从而更好地为临床决策提供依据。方法患者选择于2005年4月至2013年4月在Emory Healthcare获得至少两项ABI指数的连续患者。对连续患者进行回顾性图表回顾，以评估ABI指数值、ABI间隔时间以及两次ABI测量之间是否发生血运重建。符合条件的患者包括76例患有两种abi且在两种措施之间没有手术干预的患者。主要的研究结果测量是每天ABI的变化。每年ABI的平均变化计算为-0.012045。从这些数据推断，发现有意义的恶化(0.1)的估计时间为8.3年。结论:这些数据表明ABI的变化很小，因此，如果没有干预药物治疗来改变ABI，常规重复该测试是不合理的。
