| Angina | ||||||||
| Angina results when the coronary arteries do not deliver an adequate amount of oxygen-rich blood to the heart. | ||||||||
| This is broadly classifield as stable or unstable. | ||||||||
| Stable angina occurs when increased physical activity (ex. hurrying across a street or climbing a long flight of stairs) creates a greater demand for oxygen-rich blood to reach heart tissue. | ||||||||
