Cardiac ischemia happens when an artery leading to the heart becomes narrowed or blocked for a short time and oxygen-rich blood cannot reach your heart.
In most cases of ischemia, this temporary blood shortage to the heart causes pain in the chest (called angina pectoris).
In certain other cases, there is no pain. These cases are called silent ischemia.
Ischemic cardiomyopathy is the loss or weakening of heart muscle tissue caused by ischemia or silent ischemia.
The ischemia usually results from coronary artery disease and heart attacks.
Treatment for ischemic cardiomyopathy is similar to that for other forms of cardiomyopathy, with special attention given to treating coronary artery disease.
For patients whose hearts have been seriously damaged by ischemic cardiomyopathy, doctors may recommend that a heart transplant be considered.
