摘要: To investigate the serial changes of infarcted and noninfarcted areas, first-pass radionuclide angiocardiography was performed in 16 patients with uncomplicated anterior myocardial infarction (MI) at four weeks, one year, two years after onset MI. Global ejection fraction (EF) regional EF area improved significantly from weeks to year MI (from 39 ± 44 percent, 23 3 29 5 both p
