Background: Peripheral arterial disease (PAD) is frequently present in patients with acute ischemic stroke. However, there are limited data regarding the association between ankle brachial index (ABI) <= 0.90 (which is diagnostic of PAD) or > 1.40 (suggesting calcified arteries) and the severity of stroke and in-hospital outcome in this population. We aimed to evaluate these associations in patients with acute ischemic stroke. Patients and methods: We prospectively studied 342 consecutive patients admitted for acute ischemic stroke (37.4 % males, mean age 78.8 +/- 6.4 years). The severity of stroke was assessed with the National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin scale (mRS) at admission. The outcome was assessed with the mRS and dependency (mRS 2 - 5) at discharge and in-hospital mortality. Results: An ABI <= 0.90 was present in 24.6 % of the patients whereas 68.1 % had ABI 0.91 - 1.40 and 7.3 % had ABI > 1.40. At admission, the NIHSS score did not differ between the 3 groups (10.4 +/- 10.6, 8.3 +/- 9.3 and 9.3 +/- 9.4, respectively). The mRS score was also comparable in the 3 groups (3.6 +/- 1.7, 3.1 +/- 1.8 and 3.5 +/- 2.3, respectively). At discharge, the mRS score did not differ between the 3 groups (2.9 +/- 2.2, 2.3 +/- 2.1 and 2.7 +/- 2.5, respectively) and dependency rates were also comparable (59.5, 47.6 and 53.3 %, respectively). In-hospital mortality was almost two-times higher in patients with ABI <= 0.90 than in patients with ABI 0.91 - 1.40 or > 1.40 but this difference was not significant (10.9, 6.6 and 6.3 %, respectively). Conclusions: An ABI <= 0.90 or > 1.40 does not appear to be associated with more severe stroke or worse in-hospital out-come in patients with acute ischemic stroke.
