A study published in the European Heart Journal - Digital Health showed that the new device can detect 90% heart attacks in five minutes and without the need to take a blood sample from the patient.

Scientists have developed a device to be worn on the wrist that could revolutionize the treatment of heart attacks by speeding up diagnosis.

The device helps measure troponin - which plays a key role in causing the heart's muscle cells to contract and relax - without the need to take a blood sample.

By using infrared light through the layers of the skin (transdermally), the technology helps to detect troponin in the blood system. A change in the amount of troponin in the blood can indicate a heart attack, which is especially useful in the case of patients who don't show any changes on the electrocardiogram.

A recent study, published in the European Heart Journal - Digital Health, showed that this device can detect 90% of heart attacks within five minutes.

"With this level of precision, if you use this device and the result is positive, you are almost certain that the patient can be admitted for rapid diagnostic tests, treatment and intervention," says the study's lead author, Partho P. Sengupta. Sengupta.

According to Partho P. Sengupta, the troponin detection device could be useful for detecting heart attacks in clinics or emergency services that treat patients with chest pain. It also prevents patients from waiting for blood samples to be sent to the laboratory, analyzed and returned to the hospital, for example,

The technology could also be used for other tests to detect blood clots, ectopic pregnancy or sepsis, the study guarantees. (News/Link To Leaders/BBC).
