Body 2014 MACS ACS probability from caller-assigned ECG ischaemia, worsening angina, right-arm radiation, vomiting, observed sweating, hypotension (SBP <100), Roche hs-cTnT ng/L, and ELISA H-FABP ng/mL. Table 2 rounded coefficients. Bands p<0.02 very_low, 0.02<=p<0.05 low, 0.05<=p<0.95 moderate, p>=0.95 high. magent does not interpret ECG or assay biomarkers. Not T-MACS, HEART, or EDACS. Not a diagnosis.
