The ejection fraction was normal (65%) in the youngest patient but < 55% in the others (mean (SD) 47 (11)%). Even at a similar mass of viable myocardial tissue (as reflected by the final radiotracer content), the presence of inducible ischemia (reversible defect) was associated with an increased likelihood of functional recovery, Because improvement in global left ventricular function after revascularization is associated with enhanced survival, it is clinically important to prospectively identify patients with functionally reversible myocardium from those who have predominantly scarred, non-recoverable myocardium.

Therefore, the process can be reversed as it was not always there, which shows a presence of a dead heart muscle There will be no benefit from revascularization; (see myocardial infarctionfor more details). Soft tissue attenuation may result in an apparent fixed or reversible perfusion abnormality or defect. As myocardial blood flow at rest may remain normal, even with high-grade coronary stenosis, 7 a stress test prior to injection of the radiotracer is needed to produce flow heterogeneity between the normal and the diseased myocardial segments and to noninvasively identify hemodynamically significant coronary artery disease (CAD). Radiation can harm a developing baby or be passed to a child through breast milk. Fixed defect" vs "reversible defect"?
