Angina is pain or discomfort in the chest that lasts between 2-10 minutes. This discomfort can also be felt in the shoulders, arms, neck, jaws or back. Rest or nitroglycerin typically relieves the pain.
Types of angina include:
- Unstable angina — A more unpredictable and/or severe pattern, where chest pain may occur while resting or even sleeping (nocturnal angina), which may be a sign that you're about to have a heart attack
- Stable angina — A predictable pattern that you can expect and know how to treat beforehand
- Variant or Prinzmetal's angina — A severe, temporary contraction of coronary arteries that occurs when you're at rest
Causes of Angina
Angina is usually a sign of coronary artery disease (CAD). It occurs when the blood vessels that lead to your heart are narrowed or blocked and decrease the blood and oxygen flow to your heart. When your heart is deprived of oxygen, you will feel chest pain and other symptoms.
Other causes of angina include:
- Exercise or exertion
- Cold weather
- A large meal
- Emotional stress
Are You at Risk?
Major risk factors for CAD include the following:
- Male gender
- Increased age
- Strong family history of heart disease
- Obesity
- Smoking
- High blood pressure
- Sedentary lifestyle
- High blood cholesterol
- Diabetes
- Stress
- Excessive alcohol intake
Symptoms of Angina
The most common symptom is pressure or squeezing chest pain. Elderly people, women and diabetics are more likely to have atypical or subtle symptoms.
You're more likely to have a heart attack if you experience severe chest discomfort that lasts more than 15 minutes and is accompanied by other symptoms, such as:
- Pain in the shoulder(s) or arm(s) or into the jaw(s)
- Weakness
- Sweating
- Nausea
- Shortness of breath
Diagnosis & Treatment at UVA
At UVA, we can diagnose you by using these tests:
- Blood tests
- Electrocardiogram (EKG)
- Echocardiogram
- Exercise stress test
- Nuclear scanning
- Electron-beam CT scan (coronary calcium scan, heart scan, CT angiography)
- Coronary angiography
We offer the following treatments for angina.
Medication
Your doctor may prescribe certain medication to decrease your risk of heart attack, lower your blood pressure or prevent the progression of CAD.
Surgery
Patients with severe angina or unstable, progressing angina may benefit from:
- Coronary artery bypass graft — Arteries from other areas of your body bypass blocked heart arteries
- Coronary angioplasty — A balloon opens blocked arteries
