Paper Abstract

According to international guidelines, patients with Peripheral Artery Disease (PAD) are burdened with high cardiovascular risk. One of the simplest, non-invasive methods for PAD detection is the ankle-brachial index (ABI) measurement. The ABI is calculated as the ratio of systolic blood pressure at the ankle (pressure in the posterior tibial artery or the dorsal artery) to the systolic pressure in the arm (in the brachial artery) when the body is in a horizontal position. The physiological value of the ABI is assumed to be between 1 and 1.3; however, these limits vary from study to study. A value less than 0.9 indicates PAD. Some authors propose also measuring the ABI on both sides of the body to highlight possible differences in blood pressure between the opposite arterial segments. The aim of this study was to perform a meta-analysis of the ABI diagnostic criteria used in different publications. Additionally, ABI measurements were performed on 19 healthy patients in age ranged from 20 to 63 years. The results showed a slight dependence between age and the differences between the values obtained from left and right sides of the body.
