Abstract

We compared the left ventricular ejection fraction by echocardiography with the ejection fraction determined by computerized radionuclide ventriculography in 59 patients who were admitted to the Soon Chun Hyang University Hospotal under the impression of cardiovascular disease from May 1984 to August 1985. The results were as follow : 1) In all patients the ejection fractions by both methods were significantly correlated with each other(r=0.77, P<0.001). 2) In 10 patients with ischemic heart disease the ejection fractions by both methods were not correlated significantly(r=0.42, P>0.10). 3) Except the 10 patients with ischemic heart disease, the ejection fractions by both methods were correlated significantly(r=0.87, P<0.001). 4) In conclusion, though the ejection fraction by the above 2 methods represent the left ventricular function well, the ejection fraction by echocardiography can not represent the left ventricular function precisely in patients in patients with ischemic heart disease because of abnormal left ventricular wall motion and left ventricular function more precisely than that by echocardiography.
