Two photos on the left: The photo on the left shows healthy blood vessels. Following injection of acetylcholine, the blood vessels have dilated, and their increased size allows more blood flow, as noted in the right photo. This increased blood flow is also indicated in the before and after angiogram tracings noted directly below the photos. The EndoPAT results below this confirm these exact findings after blood flow was constricted in the brachial artery (left side graph) and then released, (right side graph), with reactive hyperemia then measured in the fingers with EndoPAT. EndoPAT features PAT (Peripheral Arterial Tone) technology, which measures the overall health of the endothelium. The PAT signal is measured from the fingertip by recording finger arterial pulsatile volume changes. Results of the 15-minute test are automatically calculated and an EndoScore is generated, which indicates thepresent state of endothelial health. Note that the redbar on theright graph, which is a marker of increased reactive hyperemia and good blood flow, is much larger than the green bar on the left, indicating good blood flow and normal endothelial function. |
