BACKGROUND: Screening program in lower extremity atherosclerotic disease (LEAD) has not been widely implemented from health systems. The aim of this study was to assess the incidence of LEAD in Greece though a pilot LEAD screening program.
METHODS: Males > 60 years old without known diagnosis of LEAD or chronic renal disease were invited through public primary health care institutions to participate in a pilot screening program in Central Greece. Demographics, atherosclerotic risk factors and other co-morbidities were recorded. LEAD was defined as ankle-brachial pressure index (ABPI) of <0.9 or >1.4.
RESULTS: Among a total of 1152 individuals (invitation acceptance 70%; 1152/1638) LEAD was detected in 13% (148); including 7% with ABPI<0.9 and 6% with ABPI>1.4. Comparing the groups with ABPI<0.9 vs normal ABPI, abnormal ABPI was associated with older age (p=0.001), hypertension (HT) (p=0.037), smoking (p=0.002), duration of smoking (p=0.01), packs/year (p=0.002), coronary artery disease (p=0.02), chronic obstructive pulmonary disease (p=0.028) and cerebrovascular disease (p=0.001). After multivariate analysis, increased age (0.94, CI. 0.026-5.2; p=0.022), history of HT (2.4, CI. 0.44- 3.7; p=0.05) and longer duration of smoking (0.9, CI. 0.01-6.1; 0.013) were associated with ABPI <0.9. Abnormally higher ABPI (>1.4) was not associated with any factor. Among those without known CAD or CVD (96/148), 37.5% (36/96) were on statins and 21% (20/96) on antiplatelets.
CONCLUSIONS: Incidence of LEAD was 13% in a male >60 years-old population of central Greece; these individuals maybe undertreated. ABPI<0.9 was diagnosed in 7% and was associated with older age, HT and duration of smoking.
