Six of the 48 patients had coronary events. non reversible would indicate necrotic (dead) 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).
