CMAT Heart, Nerve and Metabolic Test

CMAT, short for CardioMetabolic Assessment Test, is one visit of painless Measura measurements that check your blood flow, the tiny nerves, your heart rhythm and your body makeup (muscle, fat and water). Its job is to find quiet problems that can hold back healing after an injury.

You get this test only if your physician orders it. Our staff books it and keeps following up, visit after visit, until the result is in your chart.

What is CMAT?

Several Measura devices are used back to back: pressure cuffs go around the arms and ankles, small sensors clip on the fingers, and you rest your palms and the soles of your feet on flat metal plates.

Why would your physician order it?

When healing lags behind what the injury explains, something else is often in the way. CMAT screens for a few usual suspects: a thin blood supply to the legs, harm to the small nerves of the sweat glands, and a nervous system that never leaves fight-or-flight.

What does the test feel like?

Cuffs squeeze your arms and ankles briefly, small sensors rest on your fingertips, and you place both hands and both feet on metal plates. There are no needles.

How do you get ready?

Pick loose sleeves and pant legs so your arms and ankles are easy to get to. Leave out coffee, soda, energy drinks and tobacco for several hours beforehand.

What should you tell us first?

Let us know before the test if any of these apply to you:

  • A pacemaker
  • Pregnancy

How long does it take?

30 to 45 minutes.

What to remember

  1. No needles, no pain.
  2. Caffeine and nicotine wait until after the test.
  3. It screens for hidden reasons healing is slow.

Show us you have it: Before you leave, name what you will skip in the hours ahead of the test. If any part is unclear, ask us to go over it again; there is no limit on that.

Cold, numb feet are not always a nerve problem; our page on neuropathy or a circulation problem explains the difference. The small-nerve findings tie in with autonomic neuropathy and our metabolic care.
