Stable angina
Stable Angina
Stable angina (pronounced: /ˈænˌdʒaɪ.nə/), also known as angina pectoris, is a type of chest pain that occurs due to reduced blood flow to the heart. The term "angina" is derived from the Greek word "ankhon" meaning "strangling", and the Latin word "pectus" meaning "chest". This condition is typically triggered by physical exertion or stress.
Causes
Stable angina is caused by the narrowing or blockage of the coronary arteries due to the buildup of cholesterol and other substances, a condition known as atherosclerosis. This reduces the blood flow to the heart muscle, causing pain and discomfort.
Symptoms
The main symptom of stable angina is chest pain or discomfort, often described as a feeling of pressure, squeezing, or heaviness in the chest. The pain may also spread to the arms, neck, jaw, shoulder, or back. Other symptoms may include shortness of breath, fatigue, and nausea.
Diagnosis
Diagnosis of stable angina typically involves a physical examination, a review of the patient's medical history, and various tests such as an electrocardiogram (ECG), stress test, and coronary angiography.
Treatment
Treatment for stable angina includes lifestyle changes, medication, and in some cases, surgical procedures such as angioplasty and coronary artery bypass grafting (CABG). The goal of treatment is to reduce symptoms, improve quality of life, and prevent a heart attack.
