The Study on the Correlation of the Ejection Fraction(EF) of Multi Gated Blood Pool Scan(MUGA) and Echocardiography according to the condition of cardiac function

Objectives We considered the correlation of EF which was analyzed by MUGA and echocardiography for the patients who were classified according to the condition of cardiac function.

Methods We analyzed the patients (female 60) who were diagnosed with breast cancer and were examined by both MUGA and echocardiography. The 30 patients (age: 58.27 ± 13.48) who were analyzed into less than 50% to 70% of EF were categorized as normal group and the other 30 patients (age: 53.70 ± 8.45) who were analyzed into less than 50% of EF were categorized as abnormal group. Statistical analysis with SPSS ver.18 was applied.

Results Each of the value of mean and standard deviation of normal group was 66.43 ± 5.80 (MUGA), 60.50 ± 4.93 (Echocardiography). There was a significant difference (p<0.005). Each of the value of mean and standard deviation of abnormal group was 41.93 ± 7.58 (MUGA), 41.70 ± 11.49 (Echocardiography). There was no significant difference (p>0.005). In the result, all 30 cases of normal group showed the same reading. 8 out of 30 cases in abnormal group showed inconsistency of the reading.

Conclusions We could confirm the correlation of the EF in MUGA and echocardiography statistically. There was difference between abnormal groups from the result of reading. If we are aware of the result according to the different cardiac function categorization, MUGA and echocardiography can be used as even more accurate interchangeable test.
