In medicine, angina is the "symptom of paroxysmal pain consequent to myocardial ischemia usually of distinctive character, location and radiation. It is thought to be provoked by a transient stressful situation during which the oxygen requirements of the myocardium exceed that supplied by the coronary circulation."[1]
Angina may be a symptom of coronary heart disease.
Angina has three characteristics:[2]
- "Substernal chest discomfort with a characteristic quality and duration that is"
- "provoked by exertion or emotional stress"
- "relieved by rest or nitroglycerin"
Based on the number of these characteristics that a patient's chest pain has, the angina is further categorized as:[2]
- Typical angina has all three characteristics
- Atypical angina has two of the three
- Nonangina chest pain has only one of the three
Angina that occurs at rest, originally described by Prinzmetal, is now considered a variant form. [3] Subsequently, the term Prinzmetal angina is now regarded as a subset of coronary artery vasospasm[4]
The probability of underlying coronary heart disease can then be estimated (see table).[5][6][7]
