Stable angina is chest pain or discomfort that typically occurs with activity or stress. The pain usually begins slowly and gets worse over the next few minutes before going away. It quickly goes away with medication or rest, but may happen again with additional activity or stress.
Stable angina is also called chronic angina.

Angina is caused by too little blood flow to the heart. The most common cause of angina is coronary heart disease (CHD). Angina pectoris is the medical term for this type of chest pain.
Situations that increase blood flow to the heart may cause angina in people with CHD. These include exercise, heavy meals, and stress.
The risk factors for angina include:
Less common causes of angina include:
The most common symptom is chest pain that occurs behind the breastbone or slightly to the left. It may feel like tightness, heavy pressure, squeezing, or crushing pain. The pain may spread to shoulder, arm, jaw, neck, back, or other areas.
Some people say the pain feels like gas or indigestion.
The pain:
Your health care provider will perform a physical exam and measure your blood pressure. The following tests may be done to diagnose or rule out angina:
Treatment involves rest and medicine.
Medicines used to treat angina include:
Ranolazine (Ranexa) is a relatively new medicine approved for the treatment of chronic angina. The drug is for patients who do not respond to traditional angina treatment. It should be used in combination with other medication. Your doctor will tell you which ones.
Your doctor may recommend a cardiac rehabilitation program to help improve your heart's fitness.
Some patients may need surgery such as:
Recent studies show that angioplasty with stenting does not help you live longer than medicine alone, but it can reduce angina or other symptoms of coronary artery disease.
Angioplasty with stenting, however, can be a life-saving procedure if you are having a heart attack.
Stable angina usually improves with medication.
You should seek medical attention if you have new, unexplained chest pain or pressure. If you have had angina before, call your doctor.
Immediately go to the hospital if chest pain or heaviness lasts longer than 15 minutes or is not relieved with medication prescribed by your doctor. The pain may represent unstable angina or a heart attack.
Call your health care provider if:
Seek immediate medical help if a person with angina loses alertness (consciousness).
Your doctor may tell you to take nitroglycerin a few minutes in advance if you plan to perform an activity that may trigger angina pain.
The best prevention for angina is to lower your risk for coronary heart disease.
Reducing risk factors may prevent the blockages from getting worse and can reduce their severity, which reduces angina pain.
