The first step is to categorize the nature of the chest pain or discomfort. This can be done as follows:
Typical angina (definite): The characteristics of typical angina include: Substernal chest discomfort of characteristic quality and duration The pain is provoked by exercise or emotional stress The pain is relieved by rest or NTG Atypical angina (probable): Meets two of the above criteria Non-anginal pain: Meets one or zero of the anginal characteristics.
Based on the ACC/AHA 2002 guidelines,  the pretest probability can be classified into:
Low probability: less than 10%-20%; Intermediate probability: between 20%-80%; High probability: more than 80%-90%.
A quick way to assess this is shown in Table 1.
