Researchers Developed New High-Sensitivity Blood Test for Heart Attacks


Researchers developed new high-sensitivity blood test for faster diagnosis of heart attacks, according to a study published on August 6, 2018.

The newly discovered method was found to be faster in diagnosing heart attacks when compared to the conventional methods. The high-sensitivity blood test for cardiac troponin was found to be effective when it was used in a hospital emergency room. When patients are admitted in emergency rooms with symptoms of heart attack, using cardiac troponin test, doctors assessed them in part for measuring the protein that is released into the blood when the heart is damaged.

Experts of the research say that they did not miss any heart attacks using this test in the people present for the test. A high-sensitivity troponin test that is being used in Europe was recently approved by the U.S. Food and Drug Administration. A procedure was developed by the researchers for assessing the results of the new test and compared it to the existing practice using a conventional troponin test, which takes three hours to complete. 536 patients who were admitted to an emergency room with heart attack symptoms were study participants.

The results were obtained and it was found that the new procedure successfully ‘ruled out’ 30 percent of the patients immediately and an additional 25 percent at one hour. By three hours, the new procedure ruled out heart attack in 83.8 percent of patients compared with 80.4 percent using the conventional test.

Rebecca Vigen, lead author said, “We anticipate that this procedure will allow many patients with chest pain to be given a ‘yes’ or ‘no’ diagnosis of whether they are having a heart attack faster and also hopes that clinicians from other institutions will learn from these results.”
