A new blood test diagnoses heart attacks in minutes rather than hours and could be adapted as a tool for first responders and people at home.
“Heart attacks require immediate medical intervention in order to improve patient outcomes, but while early diagnosis is critical, it can also be very challenging—and near impossible outside of a clinical setting,” says lead author Peng Zheng, an assistant research scientist at Johns Hopkins University.
“We were able to invent a new technology that can quickly and accurately establish if someone is having a heart attack.”
A paper on the proof-of-concept work, which can be modified to detect infectious diseases and cancer biomarkers, appears in Advanced Science.
Zheng and senior author Ishan Barman develop diagnostic tools through biophotonics, using laser light to detect biomarkers, which are bodily responses to conditions including disease. Here they used the technology to find the earliest signs in the blood that someone was having a heart attack.
