Background: Diabetes mellitus (DM) reduces life expectancy by a third, principally because of cardiovascular disease and endothelial dysfunction is considered to be one of the first manifestations of vascular disease. Photoplethysmography is a non-invasive technique to evaluate endothelial dysfunction based on the emission of infra-red light on the skin.
Objective: To evaluate endothelial function by photoplethysmography in patients with type 2 DM without evidence of vascular disease.
Methods: A cross-sectional study of patients with and without DM was undertaken. Endothelial function was evaluated using photoplethysmographic waves taking into consideration the shape of the curve and time of maximum amplitude/total time of the curve (TMA/TT) before and after ischemia induced by arterial obstruction.
