EndoPAT Exam

At Hadassah Optimal, we want to lower you risk of a heart attack!

Heart attacks do not come out of nowhere. They are predictable and can be prevented by simple and safe evaluations. We are proud to offer our patients an innovative new procedure. This procedure, a simple exam, measures the level of endothelial levels, through which doctors will be able to predict the likelihood of a heart attack.


A few years ago, an Israeli BioTech company, “Itamar Medical” introduced an innovative new device, the EndoPAT. In 2009, EndoPAT was labeled one of the ten biggest breakthroughs in preventative medicine by "Prevention" medical journal. EndoPAT has been approved by the FDA, the European CE and the Israeli Ministry of Health. The exam provides patients with a look at the current status of their blood vessels and helps determine their level of risk for heart attacks. As many people who suffer from heart attacks also suffer from a damaged endothelial level, early diagnosis of such can help prevent future heart attacks.


The EndoPAT device is used to check the functionality of the endothelial cell layer, a main component in heart diseases. The exam is around 15 minutes long, and is done while the patient is fully clothed and in a comfortable position. The exam is not invasive or painful and nothing is injected into the patient’s body.


The endothelial cells are found all throughout the internal walls of our blood vessels and they are responsible for the flexibility of the arteries and their capability to expand when needed. Therefore the endothelial cells affect the sink rate of lipids and their rate that they will stick to blood vessel walls. Many studies have shown that many people who have suffered from heart attacks also suffer from a damaged endothelial cell layer.


How is it done?

The patient cannot eat for three hours before the exam.


Two disposable sensors will be put on one finger on each hand, and blood flow to one arm will be stopped using a special sleeve. After five minutes, blood flow will be continued. The comparison between the renewed blood flow in one arm and the blood flow in the other arm enables us to measure the sensitivity of the blood vessels, their flexibility, the quality of flow in the arteries and most importantly- the endothelial cells’ ability to secrete substances that will expand the blood vessels.


At the end of the evaluation, the functionality of the endothelial cells will be graded. The higher the grade value, the better the endothelial cells are functioning. The results are then read by a senior cardiologist and based on these results your primary care physician will be able to suggest the best follow-up treatment for you.
