Stable angina is a type of chest pain caused by reduced blood flow to the heart. It is usually caused by narrowing or blockage of the coronary arteries, which supply the heart muscle with blood. Stable angina is a common symptom of coronary artery disease (CAD). It typically occurs during physical activity or emotional stress and goes away with rest or medications.
Symptoms of Stable Angina
The main symptom of stable angina is chest pain, which may range from a dull ache to a sharp, burning sensation. It usually occurs on the left side of the chest, but it can also occur on the right side or in both arms. Other symptoms may include shortness of breath, fatigue, sweating, nausea, and lightheadedness.
Diagnosis of Stable Angina
Your doctor may diagnose stable angina based on your symptoms and medical history. Other tests may include an electrocardiogram (ECG), which measures the electrical activity of the heart, and a stress test, which measures how the heart responds to physical activity. Your doctor may also order imaging tests, such as a computed tomography (CT) scan, to examine the coronary arteries and check for blockages.
Treatment of Stable Angina
Treatment for stable angina focuses on reducing the risk of heart attack and improving your quality of life. It may include lifestyle changes, such as quitting smoking and increasing physical activity, as well as medications to reduce blood pressure and cholesterol levels. Your doctor may also recommend procedures such as angioplasty to open blocked arteries.
