Abstract

|
|
Radionuclide cardioangiography has been widely applied and has played major roles in noninvasive assessment of cardiac function. Three techniques, first-pass, gated first and gated equilibrium methods, have commonly been used to evaluate right
ventricular ejection fraction which usually abnormal in the patients with cardiopulmonary disease. It has been known that the gated first pass method is the most accurate method among the three techiques in assessment of right ventricular
ejection
fraction.
The radionuclide right ventricular ejection fraction values were determined in 13 normal subjects and in 15 patients with chronic obstructive pulmonary disease by the gated first pass method and compared with those of the first pass method
because
there
has been no published data of right ventricular ejection fraction by the gated first pass method in Korea. The values of right ventricular ejection fraction by the gated first pass method were compared with the detas from the pulmonary function
test
performed in the patients with chronic obstructive pulmomary disease.
@ES The results were as follows:
@EN 1) The values of right ventricular ejection fraction by the gated first pass method were 50.1±6.1% in normal subjects and 38.5±8.5 in the patients with chronic obstructive pumonary disease. There was statistically significant difference
between
the right ventricular ejection fraction of each of the two groups (p<0.05).
2) The right ventricular ejection fraction by the gated first pass method was not linearly correlated with FEV1, VC, DLCO, and FVC as well as PaO2 and PaCO2 of the patients with chronic obstructive pulmonary disease.
We concluded that right ventricular ejection fraction by the gated first pass method using radionuclide cardioangiography may be useful in clinical assessment of the right ventricular function.
