Angina (chest pain) that occurs regularly with activity, after heavy meals, or at other predictable times is termed stable angina and is associated with high grade narrowings of the heart arteries. The symptoms of angina are often treated with betablocker therapy such as metoprolol or atenolol.
Nitrate preparations such as nitroglycerin, which come in short-acting and long-acting forms are also effective in relieving symptoms but are not known to reduce the chances of future heart attacks.
Many other more effective treatments, especially of the underlying atheromatous disease, have been developed.
Angina that changes in intensity, character or frequency is termed unstable. Unstable angina may precede myocardial infarction, and requires urgent medical attention. It may be treated with oxygen, intravenous nitroglycerin, and aspirin. Interventional procedures such as angioplasty may be done.
