Early verification of myocardial ischemia with a novel biomarker of acute tissue damage: C-reactive protein fractional forms

► Acute tissue damage was measured by fractional forms of C-Reactive Protein (fracCRP). ► FracCRP × Troponin I (TnI) was a first-draw metric for Acute Coronary Syndrome (ACS). ► The metric identified 18% of ACS cases having TnI within the normal reference range.
