Transient LV cavity dilation is frequent on stress sestamibi SPECT. Ventricular cavity dilation is more common than global dilation and suggests subendocardial ischemia. It is related to a greater amount of jeopardized myocardium and is strongly associated with electro-cardiographic signs of ischemia.

To our knowledge, this is the largest study comparing the degree of hypoperfusion and the presence of symptoms during exercise stress testing in a consecutive cohort of patients with ischemic heart disease and reversible hypoperfusion. The results suggest that the ischemic burden is greater in painful than in silent ischemia.

In patients with severe postischemic left ventricular dysfunction undergoing rest-redistribution (201)Tl imaging, an increased lung tracer uptake showed incremental prognostic value over clinical and other imaging findings, providing clinically useful risk assessment.
