Objectives
Narrative objectives1 To compare the arteriosclerotic indicators in patients with ischemic stroke: ankle-brachial index, brachial-ankle pulse wave velocity, and cardio-ankle vascular index
Basic objectives2 Others
Basic objectives -Others Ankle-brachial index (ABI), brachial-ankle pulse wave velocity (baPWV), and cardio-ankle vascular index (CAVI) are surrogate markers of arteriosclerosis. However, analyses of these indicators in patients with ischemic stroke still remain unclear.
Trial characteristics_1 Confirmatory
Trial characteristics_2 Pragmatic
Developmental phase Not applicable

Assessment
Primary outcomes The aim of the present study was to compare ABI, baPWV, and CAVI in patients with ischemic stroke and those without a history of stroke.

Results 
Between October 2003 and September 2011, we consecutively enrolled patients with stroke presenting with large infarcts (diameter more than 1.5cm) attribute to large artery atherosclerosis (LAA) or lacunar infarcts (diameter less than 1.5cm) attribute to small artery disease (SAD). Outpatients without a history stroke were recruited as a control group (CTL). We divided the study period into two terms and assessed recruited patients using two oscillometric devises respectively in each term. Concretely, ABI and baPWV were measured using Form PWV/ABI during the former term. ABI and CAVI were measured using VaSera VS-1500 during the latter term.

A total of 1380 patients with acute ischemic stroke admitted to the Hyogo Brain and Heart Center at Himeji within 48 hours after stroke onset during the study period. Among them, we excluded 488 patients with cardioembolism and 384 patients with other determined etiology. Of 508 remaining patients, we excluded 126 patients; 69 recurrent stroke, 39 lack of data, and 18 having ABI <0.9. Hence, 382 patients with first-ever ischemic stroke consisting of 280 as SAD and 102 as LAA were enrolled. As a control group (CTL), 460 outpatients consisting of 240 recruited in the first period and 220 recruited in the second period were also enrolled in this study. Finally, we analyzed 842 patients.
