Abstract
OBJECTIVE: METHODS: RESULTS: The ABI was <0.9 in 41.1% of patients. In the multivariate analysis, absence of ≥1 pulse (odds ratio [OR], 2.18; 95% confidence interval [CI], 1.81 to 2.63; P < .0001), arterial bruit (OR, 1.92; 95%CI, 1.34 to 2.75; P < .0004), previous non-Q-wave myocardial infarction (OR, 1.50; 95%CI, 1.08 to 2.08; P = .02), regular smoking (OR, 1.49; 95%CI, 1.22 to 1.80; P < .0001), age ≥81 years (OR, 1.45; 95%CI, 1.15 to 1.82; P = .001), creatinine clearance <60 mL/min (OR, 1.33; 95%CI, 1.08 to 1.63; P = .008), and treated hypertension (OR, 1.28; 95%CI, 1.03 to 1.59; P = .03) were significantly associated with PAD. Although risk increased with the number of variables, the model, based on clinical symptoms and on medical history parameters, was not discriminatory (AUC = 0.66). On average, physicians took 15 minutes to perform the ABI test. CONCLUSIONS
