Clinical decision aids for chest pain in the emergency department: identifying low-risk patients

Figures & data

Figure 1 TIMI score and GRACE score.

Abbreviations: ACS, acute coronary syndrome; Cr, creatinine; ECG, electrocardiogram; GRACE, Global Registry of Acute Coronary Events; HR, heart rate; SBP, systolic blood pressure; TIMI, thrombosis in myocardial infarction.

Figure 2 ADAPT, NACPR, and the HEART Score.

Notes: ADAPT and NACPR, a patient is considered to be in low risk if they have none of the high-risk criteria. For ADAPT, risk factors include family history of coronary disease, hypertension, hypercholesterolemia, diabetes mellitus, and current smoker. The HEART Score; low risk =0–3, high risk =4 or greater. Risk factors include currently treated diabetes mellitus, current or recent (<90 days) smoker, diagnosed and/or treated hypertension, diagnosed hypercholesterolemia, family history of coronary artery disease, obesity (body mass index >30), or a history of significant atherosclerosis (coronary revascularization, myocardial infarction, stroke, or peripheral arterial disease).
