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.
各种检查结果支持了无功能症状和心绞痛的心肌缺血概念，这些检查已被证明在检测缺血方面可靠。无症状性缺血在不同形式的冠心病中很常见。这可能是由于缺血程度较轻，或发生在有“心绞痛预警系统缺陷”的患者中，即疼痛产生、传导或感知方面的缺陷。无症状性缺血的预后尚不确定，但似乎比各类心绞痛要好。因为即使没有疼痛，反复发生的缺血也已被证明会改变心室功能，导致缺血性心肌病。这可能是治疗这种隐匿但持续存在的综合征的一个原因。
