The Vascular Flow Study is an advanced non-invasive vascular screening device to diagnose arteriosclerosis from different angles- arterial stenosis by Ankle-Brachial Index (ABI) and arterial wall stiffness by Pulse Wave Velocity (PWV). It is a communication tool between medical professionals and patients aimed at preventing cardiovascular diseases. By bringing together the techniques of pulse wave measurements and blood pressures, the device provides easy and quantitative assessments of vascular conditions. It gives comprehensive user-specific reports to improve patient compliance with medication.


The ankle-brachial index test is a quick, non-invasive way to check for the risk of Peripheral Artery Disease(PAD). Peripheral artery disease is a condition in which the arteries in your legs or arms are narrowed or blocked. People with Peripheral Artery Disease are at a high risk of heart attack, stroke, poor circulation, and leg pain. The ankle-brachial index(ABI) test compares your blood pressure measured at your ankle with your blood pressure measured at your arms. A low ankle-brachial index number can indicate narrowing or blockage of the arteries in your legs, leading to circulatory problems, heart disease, or stroke. The ankle-brachial index test is sometimes recommended as part of a series of three tests, including the carotid ultrasound and abdominal ultrasound, to check for blocked or narrowed arteries. The Ankle-Brachial Index (ABI) indicates the existence or nonexistence of stenosis for the lower extremity artery.

Why Is It Done?

The Ankle-Brachial Index test checks for Peripheral Artery Disease (PAD), a condition in which the arteries in your legs or arms get narrowed. It is a predictive marker to detect cardiovascular disease. Pulse Wave Velocity(PWV) recognizes blood Vascular sclerosis and distensibility. When PWV is fast, arteriosclerosis for the heart, brain, or whole body is suspected.

If you are 50 years or older, consult our doctors to rule out any doubts, especially if you are:

  • A current or former smoker
  • Have Diabetes
  • Overweight (a body mass index of 25 or greater)
  • Have high blood pressure
  • Have high cholesterol

If you have already been diagnosed with PAD, your doctor may recommend having the ankle-brachial index test to see if your treatment is working or if your condition has worsened. If you have symptoms of Periphery Arterial Disease, your doctor may recommend an exercise ankle-brachial index test. In an exercise ankle-brachial index test, your walk on a treadmill for a short time before your ankle–brachial index is measured.
