Key result
Abnormal ABI affects ~21% of hemodialysis patients, tracking with age, pulse pressure, and diabetes.
Why the study?
Ankle-brachial index as a marker for peripheral artery disease and mortality prediction in hemodialysis patients was seldom studied in southern Taiwan, an area with high ESRD prevalence.
Population
225 routine hemodialysis patients in one regional hospital in southern Taiwan
Comparison
Patients with ABI < 0.9 vs ABI ≥ 1.3 vs normal ABI
Design
Cross-sectional study

Single-center observational data on abnormal ABI prevalence in southern Taiwan HD patients are hypothesis-generating; larger prospective cohorts needed to guide screening.
Cross-Sectional (n=225)
No
Chen et al. (2008) conducted a cross-sectional in End-stage renal disease (n=225). Clinical and demographic risk factors was evaluated on Abnormal ankle-brachial index (ABI < 0.9 and ABI >= 1.3). In hemodialysis patients, ABI <0.9 (15.6%) was associated with advanced age, higher pulse pressure and hematocrit, and lower albumin, while ABI ≥1.3 (5.8%) was associated with diabetes.
