The objective evidence of silent myocardial ischemia--ischemia in the absence of classical chest pain--includes ST-segment shifts (usually depression), momentary left ventricular failure, and perfusion defects on scintigraphic studies. Assessment of angina patients with 24-hour ambulatory monitoring may uncover episodes of silent ischemia, the existence of which may give important information regarding prognosis and may help structure a more effective therapeutic regimen. The emerging recognition of silent ischemia as a significant clinical entity may eventually result in an expansion of current therapy--not only to ameliorate chest pain, but to minimize or eliminate ischemia in the absence of chest pain.
无症状心肌缺血的客观证据——无典型胸痛症状时的心肌缺血——包括ST段改变（通常为压低）、短暂性左心室功能衰竭以及闪烁扫描研究中的灌注缺损。对心绞痛患者进行24小时动态监测，可能会发现无症状缺血发作，其存在可能提供有关预后的重要信息，并有助于制定更有效的治疗方案。无症状缺血作为一个重要临床实体逐渐被认识，最终可能导致当前治疗方法的扩展——不仅是为了缓解胸痛，而且是为了在无胸痛时将缺血降至最低或消除。
