Angina And Heart Health

Angina pain happens when your heart muscle does not get as much oxygen-rich blood as it needs. The cells in your heart need oxygen to work: The harder your heart muscle works, the more oxygen it needs. When cells need more oxygen than they can get, they may stop working as they should. That is why angina usually occurs when your heart is working harder than usual (for example, during physical activity) or when the blood flow to your heart muscle is lower than usual (for example, if your arteries are partially blocked).
