Abstract

Introduction: Peripheral artery disease (PAD) is a manifestation of atherosclerosis commonly associated with coronary artery disease, increasing the risk of cardiovascular events. The ankle-brachial index (ABI) is a simple, non-invasive tool to detect PAD early. However, there are limited studies evaluating the characteristics and prevalence of PAD in patients with acute coronary syndrome (ACS). Therefore, we conducted this study. Objective: This study was conducted to assess the prevalence of PAD diagnosed by the ankle-brachial index in patients with acute coronary syndrome. Subjects: Patients with first-time acute coronary syndrome treated at the Department of Cardiology and Interventional Cardiology, Cho Ray Hospital, from January 2024 to July 2024. Study design: A cross-sectional descriptive study. Results: A total of 78 subjects were included, of which 43 patients with acute coronary syndrome formed the disease group, and 35 served as the control group. The disease group had a mean age of 65 ± 8.4 years, with a male proportion of 65.1%. Common comorbidities in the disease group included dyslipidemia (93.0%), hypertension (81.4%), and type 2 diabetes mellitus (34.9%). The prevalence of PAD based on ABI ≤ 0.9 in the disease group was 32.6%, significantly higher than in the control group (2.9%). Most PAD patients were in Fontaine stage I, with only 35.7% presenting with intermittent claudication symptoms (stages IIA and IIB). Conclusion: PAD was observed in 32.6% of patients with acute coronary syndrome. Most patients were classified as Fontaine stage I, with only 35.7% reporting intermittent claudication symptoms.
