title: Ambulatory electrocardiography evaluation of asymptomatic, unstable, and stable coronary artery disease patients for myocardial ischemia.
abstract: Transient episodes of myocardial ischemia can be reliably detected by AEM in patients with known CAD. AEM appears to be particularly useful for patients in whom symptom control has been achieved with conventional antianginal drugs because many of these patients (up to 50%) continue to have residual silent ischemia that would otherwise remain undetected. Despite the lack of symptoms, numerous studies in patients with stable and unstable coronary syndromes have shown that the presence of silent ischemia during AEM is associated with an increased risk of subsequent coronary events and cardiac death. Although Holter monitoring is a practical and reliable tool for prolonged evaluation of myocardial ischemia, its routine use can not be advocated until its clinical role has been clearly defined in the ongoing large prospective studies.
