Unstable Angina Types
Types of angina include:
- Stable angina:
- Describes episodes of chest pain that are caused by coronary artery disease. However, these episodes do not worsen and are easily controlled with medications.
- Unstable angina:
- Chest pain that does not respond to usual doses of medication, such as nitroglycerin
- Chest pain that has been occurring more frequently than usual
- Chest pain that has become more severe
- Chest pains that last for longer than usual
- Atypical angina:
- Describes symptoms caused by coronary artery disease, such as nausea, weakness or sweating. However, chest pain is not present.
- Atypical angina may be stable or unstable.
- Prinzmetal's angina:
|Angina Severity||Treatment Options|
|Stable / mild or moderate||Control of cardiac risk factors; drug therapy|
