Abstract

Nonperfusion information on single photon emission computed tomographic (SPECT) myocardial perfusion imaging provides information that has implications for both diagnosis, and in cardiac prognosis and risk. The widespread implementation of (electrocardiography) ECG-gated SPECT imaging allows routine assessment of left ventricular function parameters, both at rest and following stress imaging. This review will discuss and review the recent literature surrounding a number of nonperfusion parameters that have improved the diagnostic accuracy of SPECT myocardial perfusion imaging (MPI), including transient ischemic dilation, poststress left ventricular function, regional wall motion abnormalities, and myocardial stunning. Also addressed will be the diagnostic value of pharmacologic stress ECG variables, and assessment of LV dyssynchrony and diastolic function within the setting of stress MPI.

Circ Cardiovasc Imaging. 2013;6:466–77. This prognostic study confirmed a high level of cardiac events (56 %) in diabetic patients with normal perfusion on ECG gated MPI. The presence of nonperfusion abnormalities identified a further 30 % of patients with no identified abnormality on MPI who subsequently suffered a cardiac death. This study, therefore, contributes to the evidence that not incorporating the available nonperfusion data into routine ECG gated MPI reports results in a significant risk of false negative scans in high-risk populations.

This large study evaluated the cardiac risk and its relation to both ischemia and left ventricular function in ECG gated MPI in 4575 patients. It was found that patient risk could be effectively stratified by a combination of poststress LVEF (LVEF ≤45 %, >45 %), and the percentage ischemic myocardium. Poststress LVEF is, thus, a powerful predictor of cardiac risk, and adds important prognostic information to routine ECG gated MPI.

This study confirms that dilation of the left ventricle poststress, or transient ischemic dilation (TID) is a powerful predictor of poor outcome. It was shown to be highly specific for hemodynamically significant left main coronary artery disease, high grade LAD disease and triple vessel disease and, hence, to add significant predictive value for cardiac risk.

Use of validated quantitative cutoffs has been limited by a lack of data in all protocols. This study, therefore, is important for its contribution of a validated cutoff for single day 99mTc-sestamibi rest/stress protocols. A TID ratio of 1.19 was defined as the upper limit of normal in patients with low likelihood of CAD. Validating an ED TID ratio using Gated SPECT data, with a TID ratio cutoff of 1.23, demonstrated similarly strong correlation to the presence of severe CAD, and low incidence in the low likelihood group (2 %).

This study forms part of the growing number of publications assessing the prognostic benefit of left ventricular mechanical dyssynchrony on ECG gated SPECT myocardial perfusion imaging using specialized software. In 278 patients undergoing exercise MPI, it was found that both phase standard deviation and histogram bandwidth (measures of LV dyssynchrony) were able to differentiate between patients with no or single vessel disease on angiography, and multivessel disease. It significantly improved diagnostic accuracy for the detection of multivessel disease.

This study assessed the prognostic and diagnostic value of both exercise and vasodilator stress ECG abnormalities and found that they add limited information to the MPI data. Outcome data of 3566 patients were evaluated assessing the incremental prognostic value of ST segment changes during vasodilator stress. Using a cutoff of >1 mm ST segment depression, a strong association was found between ECG changes during stress, and an abnormal perfusion scan. However, this was not independently predictive of outcome and provided no additional risk stratification.
