Treatment for myocardial ischemia involves improving blood flow to the heart muscle. The degree of reversibility of a perfusion defect is identified on post-stress images as an area of decreased radiopharmaceutical activity that improves or disappears on rest or redistribution images. Find out in this article from Missouri Medicine. Severe fixed defect most likely represents scarring or fibrosis from prior MI, but a mild or moderate fixed defect may indicate hibernating myocardium or prior nontransmural MI. It also shows how well the heart muscle is pumping. A mycocardial perfusion scan is an imaging study that shows how well blood flows through the heart muscle. Furthermore, in these patients, limited available data suggest that reversible perfusion defects on MPI confer a significantly poorer prognosis both in terms of hard event rate (MI and cardiac death) and total event rate (MI, cardiac death or late revascularization). These blood clots most commonly come from the deep veins of your legs, a condition known as deep vein thrombosis (DVT). 24 A defect was considered completely reversible if the increase in thallium activity from stress to redistribution or reinjection images resulted in final thallium uptake 85%.
