For example, concentrations of 3 chemical species, namely IIa, Tf-fVIIa-fXa, and fIXa-fVIIIa-fX, averaged over specific time windows (see Table 3) chosen relative to the time of trigger (Tf), could be used to classify ACS/CAD to an accuracy of about 87.2%. This evidence concerns the gene TF and coronary artery disorder.
