Abstract
Fourteen patients undergoing intracoronary thrombolysis for acute myocardial infarction had intracoronary injection of thallium-201 to assess myocardial salvage after reperfusion. Scintigrams of the perfused myocardium were gated and compared with both ungated scans and radionuclide ventriculograms (multigated blood pool scintigrams) to determine the value of gated perfusion images for studies of both perfusion and regional wall motion. Multigated and ungated thallium images provided comparable information about regional myocardial perfusion. Correlation between multigated thallium images of regional wall motion and radionuclide ventriculograms was poor (τ = 0.44). Assessment of wall motion was most accurate in well-perfused segments and least accurate in partially perfused segments.
