ABSTRACT: A low ankle-brachial index (ABI<0.9) is predictive of peripheral arterial disease (PAD). PAD is frequently present in patients with acute ischaemic stroke and patients with PAD demonstrate higher vascular mortality during follow-up than do those without. However, there are limited data regarding the association between low ABI and the severity of stroke. ABI is an effective and cost efficient screening tool not only for PAD but also for cardiovascular diseases. This study was aimed to determine the prevalence of low ABI among acute ischaemic stroke patients and the association between ABI and the initial severity of acute ischaemic stroke. Eighty-eight patients of first ever ischaemic stroke were enrolled and ABI measurements were done at admission. Patients were categorized into the normal (≥0.9) and low ABI (<0.9) groups. The severity of stroke was assessed with the National Institutes of Health Stroke Scale (NIHSS) and it was compared between the groups. Among 88 patients, normal ABI was present in 81.82% of the patients whereas 18.18% had low ABI. In low ABI group, 9 out of 16 patients were between NIHSS 1-15 and the remaining 7 out of 16 patients were between NIHSS 16-42. Therefore, there was no association between low ABI and the severity of acute ischaemic stroke (p=0.218). Therefore, this study showed that low ABI does not appear to be associated with more severe stroke.
