Validation of a Magnetic Sensor in Arterial Flow Recording, Compared With the Reference Method, at Various Peripheral Arterial Sites

Condition(s) studied

Investigational drug(s) / intervention(s)

Evaluation by magnetic sensor: Evaluation by magnetic sensor on arm and leg

Study summary

The measurement of magnetic fields emitted by cardiac activity has already been studied in magneto-cardiography. To date, however, this technology has never been evaluated in the peripheral circulation.

The magnetic susceptibility of iron in the circulating blood and the ionic currents in the blood stream generate a very weak induced magnetic current, which can be detected by the micro-sensor of the prototype investigators wish to study.

Proving the validity of this prototype would make it a new diagnostic and even prognostic tool, non-invasive, less costly and more accessible than Doppler for screening peripheral arterial disease.

Eligibility

Primary outcome measure(s)

• Correlation of the two curve amplitudes (y) versus time (x) between the signal recording obtained by the CapMagic prototype on the radial artery and the pulsed echo-Doppler recording on the radial artery — On day 1
  Correlation of the two curve amplitudes (y) versus time (x) between the signal recording obtained by the CapMagic prototype on the radial artery and the pulsed echo-Doppler recording on the radial artery, in adult patients with or without AOMI in hospital. The result is expressed by a Spearman correlation coefficient ranging from -1 to 1, with 0 corresponding to no correlation and 1 corresponding to a perfect positive correlation
