With heart attacks, every second counts. A new blood test diagnoses them in minutes rather than hours and could be adapted as a tool for first responders and people at home.

With heart attacks, every second counts. A new blood test diagnoses them 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," said 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."

The proof-of-concept work, which can be modified to detect infectious diseases and cancer biomarkers, is newly published in Advanced Science.
