Twenty-five patients with myocardial infarction underwent thallium-201 exercise myocardial imaging in chronic phase. Nine of these patients were treated by percutaneous transluminal coronary recanalization (PTCR), six were treated by intravenous coronary recanalization (IVCR), 15 minutes intravenous infusion of 1,920,000 IU of urokinase (UK), within 6 hours after the onset of myocardial infarction. Recanalization was angiographically recognized in these patients both in acute and chronic phases. In ten patients who were not treated by UK, recanalization was recognized in acute or chronic phase. The washout rate of thallium-201 at the center of diseased area was obtained. The improvement rate on defect score was calculated from the circumferential profile curves at 5 minutes and 3 hours after exercise. It was possible to distinguish the patterns of redistribution by the combination of washout rate and improvement rate on defect scores. In PTCR-treated group, incomplete redistribution (IR) was observed in four patients. In IVCR-treated group, partial redistribution (PR) was observed in one patient and IR was observed in two patients. In Non-UK group, PR was observed in one patient and IR was observed in two patients. The percentage of redistribution in PTCR and IVCR-treated groups was larger than that in Non-UK group.
