New paper strip test can detect heart failure

Scientists from China have developed a new paper strip test that could allow heart failure patients to monitor their condition at home.

A study on the new strip, conducted by researchers at Xi’an Jiatong University, was published in the journal ACS Nano.

The strip is fairly easy to use and only needs a small blood sample of 10 microliters to test if the cardiac biomarker ST2 is present in the sample. If it is present, a blue dot glows on the strip, and if BNP is present, a green dot glows.

If a patient’s heart failure is worsening, the colors on the strip will intensify. An accompanying smartphone app can analyze results and send data to a remote physician, who can then adjust treatment accordingly.

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.
