Blood test could detect heart attack early

Researchers in Canada are developing a new blood test that they say shows promise of becoming a quicker and more accurate method for diagnosing whether patients with chest pain are having a heart attack. The test could save lives by allowing quicker intervention to prevent more advanced heart damage and could improve the quality of life for heart attack survivors, they say. In preliminary lab studies, the test produced results in just five minutes and had a 99 percent accuracy rate, according to the researchers.
