    Abstract:
    Atherosclerosis develops simultaneously in multiple arterial beds, that creates opportunity to diagnose of coronary artery disease. Aim of the study was the evaluation of association between atherosclerotic involvement of peripheral arteries assessed by ultrasound and significant coronary artery disease revealed by angiography. Study included 410 patients, (73% males), mean age 56.0 +/- 9.5 year scheduled for coronary angiography. During ultrasound examination of common carotid and common femoral arteries arterial wall intima-media (IMT) thickness and atherosclerotic plaques presence were assessed. Significant coronary artery disease (CAD) was diagnosed with coronary angiography as diameter stenosis > 50%. Intimo-media thickness (IMT) of common carotid arteries did not differ between groups with and without significant coronary artery disease (right 6.6 vs 6.4 mm, p = ns, left 6.9 vs 6.6 mm, p = ns) but in common femoral arterial was greater in patients with coronary artery disease (right 8.2 vs 7.1 mm, p < 0.005, left 7.9 vs 7.1 mm, p = 0.03). Atherosclerotic plaques in carotid and femoral arteries was detected more often in CAD patients (90.1% vs 34.6%, p < 0.0001). Positive predictive value for CAD diagnosis with detection of plaque in carotid or femoral artery was 93% and negative prognostic value for exclusion CAD after plaque exclusion in all arteries was 61%. Search for atherosclerotic plaques in ultrasound examination of peripheral arteries may facilitate CAD diagnosis in selected patients groups.
