History: {formmenu: default=Slightly suspicious; Moderately suspicious; Highly suspicious; name=history}

EKG: {formmenu: default=Normal; Non-specific repolarization disturbance; Significant ST deviation; name=EKG} 1 point: No ST deviation but LBBB, LVH, repolarization changes (e.g. digoxin); 2 points: ST deviation not due to LBBB, LVH, or digoxin.

Age: {formmenu: default=<45; 45-64; >65; name=age}

Risk Factors: {formmenu: default=No known risk factors; 1-2 risk factors; >3 risk factors or history of atherosclerotic disease; name=riskfactors} HTN, hypercholesterolemia, DM, obesity (BMI >30 kg/m²), smoking (current, or smoking cessation ≤3 mo), positive family history (parent or sibling with CVD before age 65); atherosclerotic disease: prior MI, PCI/CABG, CVA/TIA, or peripheral arterial disease.

Initial troponin: {formmenu: default=<normal limit; 1-3x normal limit; >3x normal limit; name=troponin} Use local, regular sensitivity troponin assays and corresponding cutoffs

{=score} points {if: score<4}Low Score (0-3 points)

Risk of MACE of 0.9-1.7%.{elseif: score<7}Moderate Score (4-6 points)

Risk of MACE of 12-16.6%.

If troponin is positive, many experts recommend further workup and admission even with a low HEART Score.{elseif: score>6}High Score (7-10 points)
