Dipyridamole technetium 99m sestamibi myocardial tomography as an independent predictor of cardiac event-free survival after acute ischemic events

Abstract

We conclude that predischarge dipyridamole MIBI tomography provided independent prognostic information in this population of patients who were unable to exercise after a recent acute ischemic coronary event.

Impact of Diabetes on the Risk Stratification Using Stress Single-Photon Emission Computed Tomography Myocardial Perfusion Imaging in Patients With Symptoms Suggestive of Coronary Artery Disease

“…Although several previous studies do not show this relationship, 21 others have, particularly if the study included a high-risk population. [22][23][24] For example, in cardiac patients with ischemic events, Miller et al 23 demonstrated similar predictive values of both fixed and reversible MPI defects. Stratmann et al 24 evaluated 285 patients before nonvascular surgery and found a fixed MPI defect was associated with a cardiac event rate of 17%, compared with a rate of 12% with a reversible defect.…”

Diabetes mellitus: evaluation of patients with known or suspected coronary artery disease and the role played by myocardial perfusion imaging

“…The role of fixed perfusion defects and their relationship to the development of coronary episodes, however, has been debated in older studies. Thus, while Eagle et al [23] did not show any correlation, Miller et al [24], who studied patients with previous cardiac events, indicated the same predictive value for both reversible and fixed defects. Stratmann et al [25], who evaluated 285 patients prior to noncardiovascular surgery, found that a fixed defect on MPS was associated with an incidence of development of cardiac events of 17% compared to an incidence of 12% in patients who had a reversible defect.…”

A Technical Approach for Optimizing Surveillance of Patients with Unstable Coronary Syndromes: Continuous Vectorcardiography Ischemic Monitoring

“…More objective techniques for risk assessment of patients have been proposed during the last decades as a supplement to the medical history and examination. These include methods that assess the electrical consequences of UCS, i.e., 12-lead electrocardiogram (ECG) [3, 4], predischarge exercise ECG testing [5, 6], and continuous QRS and S-T segment monitoring [7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28]; analyses that assess the myocardial damage, i.e., myocardial biochemical markers, e.g., the troponins [6, 19, 27, 29], and tests that assess the contractile function, i.e., stress echocardiography [30], and myocardial blood flow, i.e., sestamibi SPECT scintigraphy [31]. The method of continuous vectorcardiography ischemic (QRS and S-T segment) monitoring (VCG) is increasingly used in this respect.…”
