Technology Network - Scientists from King’s College London have developed a new blood test that is more sensitive in detecting damaged heart muscle caused by a heart attack. In a paper published today in the journal Clinical Chemistry, the team investigated how many heart muscle cells needed to die before they could be detected in the blood stream.
Currently, patients with chest pain are responsible for 2.2 million admissions to Emergency Departments every year. Of those suspected of having suffered a heart attack, only a small proportion are shown as having diagnostic changes on a heart trace or ECG.
