Chest pain traditionally has been classified into typical and atypical types. Chest pain that is more likely associated with ischemia includes of substernal chest discomfort aggravated by exertion or emotional stress and relieved by rest or nitroglycerin. Ischemic chest discomfort  can be described based on quality, location, radiation, and provoking and relieving factors. Using the term of atypical chest pain is problematic. Although the term of atypical chest pain was intended to describe angina without typical chest symptoms, it is more often used to consider that the symptom is noncardiac in origin. Then, based upon the ACC/AHA Guideline 2021, it is discouraged to use the term of atypical chest pain. Notably, chest pain is a broadly term to define referred pain in the shoulders, arms, jaw, neck, and upper abdomen. So, using the terms of cardiac, possible cardiac, and noncardiac are encouraged to describe the nature of chest pain.
