Body 2016 T-MACS logistic ACS probability from caller-assigned ECG ischaemia, wo

Body 2016 T-MACS logistic ACS probability from caller-assigned ECG ischaemia, worsening angina, right-arm radiation, vomiting, observed sweating, hypotension (SBP <100), and Roche Elecsys hs-cTnT ng/L. Uses that paper's 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 troponin. Not original MACS, HEART, EDACS, or Vancouver. Not a diagnosis or medical device.
