Heart
- The HEART (History ECG Age Risk factors Troponin) score was developed for undifferentiated patients with possible ACS [21].
- It considers history [8], ECG findings, age, risk factors and initial troponin.
- Low risk patients have a 0.9 – 1.7% 6 week risk of a Major Cardiac Event (MACE). After a repeat 3 hour negative troponin, they can be discharged with outpatient follow up.
- High risk patients require admission and serial assessment [21].
