Thus, a dysfunctional but viable myocardial region may have reduced (but not absent) blood flow at rest (termed hibernation), or transient reduction in blood flow after a period of ischemia (termed stunning).4,5 Regional left ventricular dysfunction arising from a transient period of myocardial ischemia (reversible defect) may improve after revascularization, while regional dysfunction arising from transmural or non-transmural myocardial infarction (fixed defect) may not recover function after revascularization. We consider a fluctuation test experiment in which cell colonies were grown from a single cell until they reach a given population size and were then exposed to treatment. Small defect in the apical anterior wall,which is completely reversible, consistent w/ ischemia.Attenuation artifact cannot be ruled out. When both viable myocardium and scarred myocardium are present, the defect may be characterized as mild-moderate fixed, which connotes non-transmural infarction, and can also be seen after percutaneous coronary intervention in the setting of acute coronary syndrome (Table 1 ).

Of the 11 asynergic regions with normal stress thallium, 10 (91%) demonstrated improved systolic wall thickening after revascularization. In other cases, ischemia is possibly reversible when the affected tissue resulted in death. This may be achieved with improvement in coincidence time resolution (lower than 100 ps) through new PET detector designs, and some day even crossing the 10 ps, which will increase the performance of time-of-flight PET dramatically, resulting in a better signal-to-noise ratio of the activity measurement (e.g., F-18 Flurpiridaz), improving the reconstruction process and rendering quantifying the endocardial-to-epicardial distribution of myocardial blood flow achievable and attainable. This may involve either a stress echocardiogram or a nuclear stress test because these tests are more accurate.
