Abstract:Pulse wave velocity (PWV), developed in recent years, is an early and sensitive indicator for arterial elasticity and stiffness. It has been gradually applied in clinical practice since it is non-invasive, easy to operate, and of good repeatability. Both non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome promote the development and progress of atherosclerosis, so PWV is helpful to identify the patients with early-stage atherosclerosis. The article reviewed the literatures concerning brachial-ankle pulse wave velocity (ba-PWV) and NAFLD as well as metabolic syndrome.
