The ankle-brachial index (ABI) is a good tool to evaluate
systemic atherosclerosis [8] and the outcome of cardiovas-cular disease. An ABI less than 0.9 is highly sensitive and specific for the diagnosis of peripheral arterial occlusive
disease (PAOD) [9], which is a prominent risk factor for
ischemic heart disease and cardiovascular mortality [10].
The aim of this study was to evaluate whether low ABI is
a good predictive factor for determining renal outcome and
cardiovascular events in patients with CKD.
