Chest PainHow do you risk-stratify undifferentiated chest pain patients in the Emergency Department? There are a multitude of causes for chest pain. We are always taught to think of the 5 big life-threats: ACS, PE, aortic dissection, tension pneumothorax, and pericardial tamponade.

So how do YOU risk-stratify your patients for unstable angina (UA) and non-ST elevation myocardial infarction (NSTEMI)? STEMI’s are usually obvious. UA and NSTEMIs — not so much.

Fortunately a 2000 JAMA article and a followup Academic Emergency Medicine 2006 study have solidified the TIMI risk scoring system as a reasonable risk-stratification tool for all-comer ED patients with chest pain requiring an ECG.

Generally there is an upslope in risk at a TIMI score of 3 and greater.
