Testing your blood for the special protein enzyme ST2 to help manage the risk of heart attack

A heart attack causes special proteins to leak into your blood. One of these proteins is called ST2. Measuring the level of this cardiac biomarker in your blood can indicate where, and to what degree, the heart is damaged. Identifying this damage can help determine how you are responding to treatment.
