Is angina caused by anemia

Angina is typically caused by reduced blood flow to the heart muscle, often due to coronary artery disease. While anemia can lead to decreased oxygen delivery to tissues, including the heart, it is not a direct cause of angina. However, severe anemia may exacerbate existing heart conditions or contribute to angina symptoms in susceptible individuals. Therefore, while anemia can influence heart health, it is not a primary cause of angina.
