- While certain aspects of the history, exam, and EKG may increase likelihood of ACS, there is no one element that performs well on its own
- Elements of the history have been found to have different likelihood ratios, which can increase or decrease the probability of a patient having ACS
- Likelihood ratios greater than one increase the chance of the patient having the disease. Ratios less than one decrease it
- Bilateral arm radiation is one of very few historical features that increases the likelihood of ACS
- ST depressions are one of the few EKG findings with a high LR for ACS
- Scoring systems such as the HEART score can be useful to risk stratify your patients
