Wireless Implant Predicts Heart Attack Hours In Advance

A team of EPFL scientists led by Giovanni de Micheli and Sandro Carrara have developed a 14mm implant that can wirelessly monitor substances in the bloodstream, sending data directly to a doctor’s computer. The tiny device is inserted just under the skin to analyze the concentration of up to five proteins and organic acids simultaneously.

It includes five sensors, a radio transmitter, and a power delivery system. Inserted into the interstitial tissue just beneath the skin of the abdomen, legs or arms using a needle, it can remain in place for months before needing to be replaced.

Wireless Implant Can Predict Heart Attacks Hours In Advance

The Verge reports that the device can predict heart attacks three to fours hours in advance by detecting a molecule called “troponin,” which is released by the heart muscle once it starts malfunctioning. This way, if someone has the device implanted, they would know that a heart attack is coming and could better prepare.

The scientists are going to test the device on intensive care patients, who require a lot of close monitoring, and hope it will be made available within four years. You can check out the video below to learn more:
