Peripheral arterial disease is usually measured with ankle brachial index (ABI). It is previously shown that the ABI would reflect LV systolic func-tion, as well as atherosclerosis; however, these results are not shown in non-diabetic indi-viduals. In this study, we aim to evaluate this relation in non-diabetic individu-als.Methods: In a prospective study, 73 non-diabetic individuals (38.4% male with mean age of 59.20±14.42 years) referred for ABI determination who had had the left ventricular ejection fraction determined using trans-thoracic echocardiography were studied. Partici-pants were compared in normal and low ABI groups. Results: The mean left ventricular ejection fraction (LVEF) was 52.34±7.69, mean ankle brachial index for the right leg was 1.08±0.13, and the mean ankle brachial index for the left leg was 1.07±0.12. Low ABI incidence was 12.32%. Individuals with low ABI significantly were older (p<0.001) and had lower left ventricular ejection fraction (p<0.001). ABI had significantly inverse corre-lation with LVEF (r=-0.53, p<0.001) and positive correlation with age (r=0.43, p<0.001). The ABI correlated inversely with LVEF in the patients with (r =-0.52, p=0.008) and without (r=-0.55, p<0.001) IHD. Conclusion: Results showed that ankle brachial index would be influenced by left ventricular ejection fraction in non-diabetics and to evaluate and monitor cardiovascular risk in patients these should be considered together.
