Can anemia cause myocardial ischemia?

Anemia can cause myocardial ischemia, depending on the type of disease, severity and other factors to judge.

If the patient has chronic anemia, and the disease is mild, hemoglobin concentration remains at a relatively normal level, usually does not cause myocardial ischemia. However, if the patient has severe disease, excessive hemoglobin concentration can lead to myocardial hypoxia, resulting in myocardial ischemia.

If the patient has acute anemia, it can lead to a sharp drop in hemoglobin, resulting in insufficient oxygen supply to the heart, hemodynamic changes, increased cardiac load, resulting in increased cardiac burden, resulting in myocardial ischemia.
