EndoPAT™ is a safe, accurate, and non-invasive diagnostic test used to determine the health of your blood vessels.

Performed just like taking your blood pressure, this 15 minute test assesses the endothelial function of the blood vessels by measuring the blood flow through your arteries before and after a blood pressure cuff is applied. The results are available in minutes.


  • Simple, in-office test
  • Non-invasive
  • Painless
  • Quick — 15 minutes
  • FDA-cleared
  • Highly accurate & reproducible
  • No radiation exposure


The endothelium is the inside lining of your blood vessels. The cells of the endothelium control how your blood vessels dilate or constrict to maintain blood pressure and blood flow throughout your body. Normal endothelial function also protects blood vessels from forming plaque and blockages. When your endothelium is damaged because of high blood sugar, high insulin, high cholesterol, or high blood pressure, your blood vessels do not dilate normally. This, in turn, puts you at increased risk for heart attacks, strokes, kidney failure, poor circulation, gangrene, and other complications. Endothelial dysfunction is damage in progress — the sooner it is diagnosed the quicker and better it can be reversed.

Who should take the EndoPAT™ test?

EndoPAT™ testing is highly recommended for patients with any of the following risk factors for heart disease:

  • Tobacco user
  • High blood pressure
  • Elevated cholesterol
  • Diabetes or prediabetes
  • Family history of heart disease
  • Obesity
  • Sedentary lifestyle

In addition, EndoPAT™ testing may uncover underlying coronary artery disease in asymptomatic patients without identifiable risk factors.


How do I prepare for the test?

At least 3 hours prior to the test, do not eat, drink only water, and do not smoke (including e-cigarettes and other nicotine replacements). Dr. Gutman may instruct you to stop certain medications the day before the test.


How is the EndoPAT™ test performed?

Step 1: A standard inflatable blood pressure cuff is placed around one arm. Special finger sensors connected to the EndoPAT™ recording device are placed over the index finger of each hand to monitor the blood flow at the fingertips.

Step 2: After about 5 minutes, the blood pressure cuff is inflated, which temporarily stops the flow of blood through the arm and hand. After another five minutes, the blood pressure cuff is deflated, allowing blood flow to resume.

Step 3: The special finger sensors monitor reactive hyperemia, which is the normal increase in blood flow that occurs when the blood pressure cuff is released and blood returns to the fingertips. The EndoPAT™ then automatically analyzes the data and your results are printed on a graphical report that you can take home.
