"Summary and Takeaways:
- The risk of ACS in patients with negative biomarkers and normal ECGs approaches 0.2%.
- Prior risk scores, such as TIMI and GRACE, provide little, if any benefit, in risk stratification for ED chest pain patients.
- The HEART score and pathway can risk stratify patients into three separate categories: low (0-3), moderate (4-6), and high score (> 7).
- Low risk patients on the HEART pathway demonstrate likelihood of ACS that approaches < 1%, and it is easy to use in the ED.
- Risk factors, history, ECG, troponin, follow up, gestalt, patients with points 3 or 4, and research design are areas of potential weakness.
- Further improvement of the HEART pathway at this time is difficult, but in patients at moderate risk, CCTA may hold promise for evaluation of risk. This requires further study."
