What is an Endo PAT?
Listen to pronunciation. (EN-doh-pat) A medical device that tests to see if endothelial cells are damaged. Endothelial cells line the inner walls of blood vessels, lymph vessels, and the heart, and damage to them may be an early sign of heart disease.
What does EndoPAT measure?
The EndoPAT detects plethysmographic pressure changes in the finger tips caused by the arterial pulse and translates this to a peripheral arterial tone (PAT).
What is an endothelial function test?
The endothelial function test is noninvasive. It is designed to measure blood flow through the arteries. The score that results from the test predicts your risk for heart disease.
What is a normal RHI?
Normal: RHI > 1.67. Abnormal: RHI ≤ 1.67.
What is epithelium and endothelium?
Endothelial cells cover the blood vessel inner surface, while epithelial cells cover outer surface of the internal organs and the body. The endothelial cells and epithelial cells are derived from the epithelium, but they have differences in position, structure, and function.
What’s the difference between epithelium and endothelium?
Endothelium generally lines fully internal pathways (such as the vascular system), while epithelium generally lines pathways that are open to the external environment (such as the respiratory and digestive systems). Nerve cells are specialized for signaling, and red blood cells are specialized for oxygen transport.
What is epithelium?
The term “epithelium” refers to layers of cells that line hollow organs and glands. It is also those cells that make up the outer surface of the body.
What kind of Technology is used for Endo-Pat?
Endo-PAT is based on noninvasive Peripheral Arterial Tone (PAT) signal technology. It measures endothelium-mediated changes in vascular tone using unique bio-sensors placed on the fingertips.
How is the post occlusion ratio calculated in Endo-Pat?
A post-occlusion to pre-occlusion ratio is automatically calculated by the Endo-PAT software, providing the Endo-PAT index. Measurements from the contra-lateral arm are used to control for concurrent nonendothelial dependent changes in vascular tone.
Where can I get an endothelial function test?
The Holistic Healing Heart Center is able to offer EndoPAT testing to our patients who want to receive information about their cardiovascular health.
What causes an increase in the endo-Pat signal?
When the cuff is released, the surge of blood flow causes an endothelium dependent Flow Mediated Dilatation (FMD).The dilatation, manifested as Reactive Hyperemia, is captured by Endo-PAT as an increase in the PAT Signal amplitude.
