Non-ST-Elevation Acute Coronary Syndrome Prognosis

2010, Annals of Emergency MedicineCitation Excerpt :With more than 5 million annual hospital admissions, and at a cost of more than $10 billion, most patients (>60%) are found to have noncardiac chest pain.1 Stress tomographic myocardial perfusion imaging (SPECT) can effectively identify these low-risk patients2 but generally requires a prolonged stay in the ED or admission to an observational chest pain unit. To develop an efficient ED-based approach, an accurate, readily available imaging method is needed to rapidly distinguish ischemic from nonischemic conditions, thereby facilitating direct discharge home or appropriate hospital admission.
Patient preparation for nuclear imaging: When should anti-ischemic medications be withheld?
2007, Journal of Nuclear CardiologyMyocardial metabolic imaging in the acute care setting
2007, Journal of Nuclear CardiologyCitation Excerpt :Typically, exercise or pharmacologic stress testing in conjunction with perfusion imaging is used to rule out myocardial ischemia and thereby determine who can be discharged home or admitted for further evaluation. Considerable prognostic data for patients with unstable angina17-21 and for post-AMI patients22-29 have been published, indicating that the presence and extent of stress-induced myocardial ischemia predict subsequent outcome. Recently, the adenosINe Sestamibi SPECT Post-InfaRction Evaluation (INSPIRE) investigators showed in 728 patients that adenosine Tc-99m sestamibi SPECT performed early after hospital admission for AMI with ST-segment elevation and AMI with non–ST-segment elevation could identify a low-risk population accurately where medical therapy and early hospital discharge are appropriate.30,31
