Abstract:
OBJECTIVE: Left ventricular ejection fraction is an important clinical variable with respect to diagnosis, treatment and prognosis in various cardiovascular diseases. Measurement of left ventricular ejection fraction is performed by three commonly used methods, M-mode and two dimensional echocardiography, radionuclide angiography and contrast cineangiography. We compared echocardiographic and contrast cinean-giographic ejection fraction by correlation coefficiency to determine the accuracy of echocardiography determined ejection fraction at our institution and to assess the agreement of left ventricular ejection fraction between two methods. METHODS: We measured left ventricular ejection fraction by M-mode, two-dimensional echocardiography and contrast cineangiography in 144 cases of normal and cardiovascular heart disease patients from September 1993 to April 1995 in the cardiology division of Ewha Womans University hospital. The echocar-diography and contraat cineangiography were performed within 7 days of each other. RESULTS: M-mode echocardiographic ejection fraction correlated with contrast cineangiographic ejection fraction (r=0.7841). M-mode echocardiographic ejection fraction corrected with two-dimensional echocardiography in the presence of regional wall motion abnormality correlated with contrast cineangiographic ejection fraction (r=0.8149). By agreement analysis, the difference of mean of ejection fraction measured by M-mode echocardiography and contrast cineangiography was within 95% confidence limits. The mean was 4.08% and the standard deviation was 8.29%. The difference of mean of ejection fraction corrected by two-dimensional echocardiography and contrast cineangiography was within 95% confidence limits. The mean was -3.19% and the standard deviation was 7.74% CONCLUSION: The values of left ventricular ejection fraction by echocardiography showed good correlation with those of contrast cineangiographic ejection fraction, Therefore, echocardiography would be a useful tool as contrast cineangiography in evaluating the left ventricular function.
