Abstract

Introduction: Hypertension (HTN) is a common chronic disease among the elderly, associated with various cardiovascular complications, including peripheral arterial disease (PAD). However, screening for PAD remains underused. Measuring the ankle-brachial index (ABI) is a simple and convenient method for screening and early detection of PAD. Objective: Evaluation of ABI characteristics and some risk factors related to PAD in elderly patients with HTN at Can Tho University of Medicine and Pharmacy Hospital in 2023. Methods: A cross-sectional descriptive study using a convenience sampling method was conducted on 51 elderly patients with HTN. ABI was categorized using the following thresholds: ABI≤0.9 (PAD), 0.91–1.4 (normal), and ABI>1.4 (arterial calcification). Information on risk factors for PAD was also collected. Results: The mean ABI of the study population was 1.23±0.19, with 5.9% of patients having ABI≤0.9. ABI was significantly associated with higher BMI and the severity of HTN. Conclusion: Measuring ABI is an effective tool for the early detection of PAD in elderly patients with HTN, especially among those with high BMI and severe HTN. The findings highlight the importance of managing body weight and blood pressure to prevent PAD in HTN patients.
