Answer: Angina often occurs when the heart muscle needs more blood than it's getting, such as during physical activity like climbing a hill or stairs, or when you're having strong emotions.
Step-by-step explanation:
Stable angina, also called angina pectoris, is the most common type of angina. Stable angina is a predictable pattern of chest pain. You can usually track the pattern based on what you're doing when you feel the pain in your chest.
good luck!
