Categorization of abnormal left ventricular function: comparison between radionuclide angiographic and echocardiographic technique in postinfarction patients.
In postinfarction patients, only biplane echocardiographic evaluation of left ventricular ejection fraction (EF) accurately predicts radionuclide EF > or <0.35, 0.40, and 0.45. A wall motion scoring system that does not account for hyperkinesia of healthy myocardium may be used to discriminate between radionuclide EF > or <0.40 or 0.45, but lacks accuracy for 0.35.
