What does angina refer to?

Angina refers specifically to chest pain that occurs when the heart does not receive enough blood, which often happens due to narrowing or blockage of the coronary arteries. This type of pain is typically described as a feeling of pressure or squeezing in the chest, and it can also radiate to other areas such as the shoulders, arms, neck, jaw, or back. Angina is often a symptom of an underlying heart condition, such as coronary artery disease. Understanding angina is crucial for patient care technicians as it can be an important indicator of cardiac issues needing immediate attention. The condition may arise during physical activity or stress and often resolves with rest or medication.
