CAD Silent Ischemia. Thank you very much.
Ischemia refers to an inadequate blood supply to the heart muscle.
This can often be seen on an electrocardiogram. Silent ischemia means that this inadequate blood supply is not causing symptoms, although it may cause problems. Many people still believe that all heart disease causes chest pain, and although this is often true, it is not always. Classical angina pectoris is the pain caused by ischemia, but for the last 20 years or so doctors have realized that ischemia can occur without pain, and often does. Even someone who regularly has anginal pains may have silent ischemic attacks.
