An apparatus for measuring functionality of an arterial system of an individual includes a photoplethysmography sensor for emitting, to the arterial system, electromagnetic radiation having a wavelength in the range from 475 nm to 600 nm and for receiving a part of the electromagnetic radiation reflected off the arterial system. The apparatus further includes a pressure instrument for managing mechanical pressure applied on the arterial system when the photoplethysmography sensor emits and receives the electromagnetic radiation to and from the arterial system. The effect of the mechanical pressure on the envelope of the reflected electromagnetic radiation can be used for determining diastolic blood pressure of arteries or for determining whether there is normal endothelial function.
