  • Patent number: 9365888
    Abstract: Methods for characterizing the near term risk of experiencing a major adverse cardiac event in a patient presenting to an Emergency Department with chest pain are provided. In one embodiment the method comprises determining the level of myeloperoxidase (MPO) activity and/or mass in a bodily sample obtained from the patient. Levels of MPO activity or MPO mass in bodily samples from the test subject are then compared to a control value in comparable bodily samples obtained from a control population. Such comparison can also be used to determine the near term treatment of the patient.
