Abstract

Purpose: To evaluate the prevalence of peripheral artery disease in patients with cerebral infarction and assess age- and sex-related differences, as well as associated risk factors.

Methods: We enrolled 2,228 stroke patients aged over 40 years with a history of cerebral infarction from our outpatient clinic. Baseline medical conditions and Ankle-Brachial Index (ABI) measurements were recorded.

Results: The prevalence of abnormal ABI was 13.5%. ABI values decreased with advancing age. In the risk factor analysis, diabetes, hypertension, and atrial fibrillation were significantly associated with abnormal ABI values, with odds ratios of 1.47, 1.74, and 2.28, respectively.

Conclusion: Older age was strongly correlated with abnormal ABI values. Additionally, diabetes, hypertension, and atrial fibrillation were identified as significant risk factors for abnormal ABI in stroke patients.
