Angina is a type of chest pain or discomfort that occurs when the heart muscle does not get enough oxygen-rich blood. It is often described as a feeling of pressure, tightness, or squeezing in the chest. Angina can be triggered by physical strain, emotional stress, or exposure to cold temperatures. It is typically a symptom of underlying heart disease, such as coronary artery disease, where the arteries that supply blood to the heart become narrowed or blocked by fatty buildup called plaque. While angina itself is not a heart attack, it can be a warning sign of a future heart attack. Treatment for angina may involve medications to relieve symptoms and reduce the risk of complications, lifestyle changes such as quitting smoking and adopting a heart-healthy diet, and procedures such as angioplasty or bypass surgery to improve blood flow to the heart. Immediate medical attention is important for anyone experiencing angina symptoms to prevent complications and manage heart health effectively.
