Angina (Chest Pain)
Angina, or chest pain, is the result of myocardial ischemia, which is an improper blood flow through the vessels supplying the heart. It’s caused by the imbalance of blood supply and oxygen demand of the heart.
Myocardial ischemia can result from atherosclerosis, a buildup of fat and cholesterol that reduce the area inside vessels for blood to flow to the coronary arteries. Other causes of angina include a coronary artery spasm or decreased oxygen-carrying capacity of blood. Angina is an indicator for heart disease.
The risk factors for angina include:
- Cardiomyopathy, or disease of the heart muscle
- Collagen vascular diseases
- Congenital heart defects
- High cholesterol
- Metabolic syndrome
- Syndrome X, which is chest pain without blockages in the arteries, often found in women
Symptoms of Angina
Angina is chest discomfort or pain, usually a pressure or heaviness. It can also feel like a squeezing of the chest or a burning feeling.
Other common signs include:
- Pain can also be felt in the back, neck, chest, jaw, or shoulders.
- Pain does not change with cough or breathing.
- Pain is usually brought on by exertion, eating, cold, or stress.
- Pain lasts 1-5 minutes and is relieved by nitroglycerin.
Diagnosis of Angina
Unless there are other causes, your doctor can usually diagnose angina through a normal physical exam.
Other diagnostic techniques include:
- Coronary angiography – assesses coronary arteries for blockage
- Electrocardiogram (ECG) tracks changes in the amount of time from the chambers contracting until resting
- Graded exercise stress test performed with or without echocardiography or myocardial perfusion tests
- Levine sign – describes the pain by clenching your first over your chest
- Myocardial perfusion study – evaluates perfusion defects
- NYHA classification:
- Class I – ordinary physical activity; does not cause symptoms
- Class II – ordinary physical activity; does cause symptoms
- Class III – comfortable at rest, but less than ordinary activities cause symptoms
- Class IV – symptomatic at rest
- Stress echocardiography evaluates changes in heart wall motion during exercise
Angina Treatment Options
Lifestyle changes often are a part of treating angina. Common treatment options include:
- Aspirin daily to thin blood
- Beta-blockers and calcium-channel blockers for improving blood flow
- Exercise training to improve blood flow
- Intra-aortic balloon pump for unstable angina not controlled by medications
- Nitroglycerin placed under the tongue for symptomatic episodes
- Nicotine cessation
- Angioplasty and stenting
- Coronary artery bypass graft
- Treat diabetes, hypertension, obesity, and high cholesterol
