ABSTRACT Background: Data from population studies using ankle⊟brachial index (ABI) measurement to screen patients for peripheral arterial disease (PAD) demonstrate that most patients with PAD have no symptoms or atypical symptoms besides classical intermittent claudication. We aimed at comparing health-related quality of life and ABI in a cohort of cardiovascular risk persons in a general population. Methods: SF-36 questionnaire was completed and ABI measured from 915 individuals aged 45-70 years with hypertension, metabolic syndrome, pre-diabetes, newly detected diabetes, body mass index ≥30 kg/m(2), or a 10-year risk of cardiovascular disease death of 5% or more according to the Systematic Coronary Risk Evaluation (SCORE) system. None of the subjects had symptoms of intermittent claudication. Results: The prevalence of PAD (defined as ABI ≤0.90) and borderline PAD (defined as ABI 0.91-1.00) were 5% (95% CI 4-7%) and 20% (95% CI 18⊟23%), respectively. Patients with PAD had significantly lower quality of life dimension scores for physical functioning, role-physical, general health, and vitality than subjects with normal ABI. Among those with borderline PAD, quality of life was reduced on the general health perception compared to subjects with normal ABI. Conclusion: Health-related quality of life of individuals with asymptomatic or atypical PAD or borderline PAD is worse than that of individuals with normal ABI. The level of ABI is independently related to physical functioning.

    ABSTRACT: We evaluated health-related quality of life (HRQoL) among patients with peripheral arterial disease (PAD) and compared the results with those of the general population. We also evaluated the possible association between some demographic and clinical characteristics of patients with PAD and HRQoL. A cross-sectional study involved 102 consecutive patients with verified PAD referred to the Dedinje Vascular Surgery Clinic in Belgrade. The HRQoL was measured using Medical Outcome Survey Short Form 36 (SF-36). Patients with PAD had significantly lower mean SF-36 scores for physical functioning, role-physical, bodily pain, social functioning, role-emotional, and mental health in comparison with the general population. The HRQoL was significantly more impaired in patients with severe PAD. Patients with PAD had a reduced HRQoL compared with the general population. The impact of PAD on HRQoL was independent of other factors related to both the disease and the HRQoL.
