What is the AngioDefender™?

The AngioDefender™ helps assess the presence of early-stage cardiovascular disease (CVD) and coach individuals on how to improve their overall vascular health. Until the AngioDefender™, measuring damage to your arteries required highly technical, expensive, and often invasive procedures. The AngioDefender™ is not only accurate, but is non-invasive and can assess your overall risk of CVD in less than 20 minutes.

How Does the AngioDefender™ Work?

The AngioDefender™ measures the percentage of difference in diameter between fully dilated and resting blood vessels, known as flow-mediated dilation (%FMD). Healthier vessels release more nitric oxide, leading to a higher %FMD and a lower risk of CVD and atherosclerosis.

The results from the AngioDefender™ test are inputted into the Vascular Age Calculator along with some additional information about the individual, which together enables us to get a good understanding of your vascular health. Our trained staff can then identify any CVD risk factors affecting your vascular age and develop a customized plan to improve your overall health and well being.

Why Should I Get an AngioDefender™ Heart Health test?
  • Cardiovascular Disease is responsible for nearly one of every three deaths per year
  • Nine in ten Canadians have at least one risk factor for heart disease and stroke
  • More people throughout the world die from Cardiovascular Disease than any other cause
  • The test is portable, quick, non-invasive, accurate, and provides instant results
  • Up to 80% of premature heart disease and stroke is preventable by adopting healthy behaviour
  • Most people don’t have symptoms before their first heart attack. This is why CVD is known as “the silent killer”
