[Silent myocardial ischemia].
The concept of myocardial ischaemia without functional symptoms and anginal pain is supported by the results of various examinations which have proved reliable in detecting ischaemia. Silent ischaemia is common in different forms of coronary disease. It may be due to the ischaemia being moderate or occurring in patients with a "defective anginal warning system", i.e. a defect in the genesis, transmission or perception of pain. The prognosis of silent ischaemia is uncertain, but it seems to be better than that of various types of angina pectoris. Because it is repetitive ischaemia, even without pain, has been shown to alter the ventricular function, resulting in ischaemic myocardiopathy. This may be a reason for treating this insidious but unrelenting syndrome.
