Researchers for this paper sought “to determine volubility of SPECT in the management of patients admitted to emergency department with atypical manifestations of angina pain, undiagnostic ECG and negative enzyme.” The study looked at data from half of a population 100 patients who upon admission with atypical chest pain and undiagnostic ECG underwent ECG-gated resting SPECT. Low-risk patients were discharged after negative stress SPECT, and patients were followed for major cardiac events such as cardiac death, nonfatal myocardial infarction, and repeat admission for heart failure. According to the results of SPECT myocardial perfusion imaging, almost 70% of in the study sample were classified as low risk and 30% as moderate or high risk. The study intervention group also had lower costs than the control group (P<0.001). “Our study showed that rest SPECT fulfillment in admitted patients in the emergency department was validated method for assessing patients’ risk, which avoids unnecessary hospitalizations and additional costs,” the researchers wrote.
