One-hundred subjects were selected from a convenience sample. The “risk” of AMI diagnosis was modeled using binary multiple logistic regression. Overall, 78% (39 out of 50 cases) were diagnosed with an AMI at Tinitial. Clearly, the initial cTnI assay is the most critical of the four sequential time points for the accurate assessment of the presence or absence of an AMI. Most importantly, sequential troponin testing increased the ability to diagnose AMI by 10-fold.ABBREVIATIONS: ECG - electrocardio-gram, CK - creatine kinase, AMI – acute myocardial infarction, cTnI - cardiac troponin I, CSRA - Central Savannah River Area, STEMI - ST-elevation myocardial infarction
