Two-dimensional echocardiography and gated blood radionuclide angiography was performed in 50 patients (mean age 51.3 years; 48 men and 2 women) after acute myocardial infarction, before discharge from the hospital. The aim of this study was to compare the wall motion score, determined by two-dimensional echocardiography (2DE), with the ejection fraction obtained by radionuclide angiography (RNA). The correlation between the results obtained by 2DE and RNA was good (r = 0.75; p less than 0.0001). We conclude that 2DE is a powerful diagnostic tool for the evaluation of left ventricular function.
