Table 3. Comparison of Echocardiography Parameters before (0 Month) and after (3 Months) RT.

Parameters	0 Month	3 Months	P
LVEF (%)	69.2 ± 5.0	71.5 ± 7.4	0.398
LVEDd (mm)	31.3 ± 3.2	32.4 ± 3.1	0.418
LVEDs (mm)	19.9 ± 2.0	18.2 ± 3.9	0.236
E/A	1.87 ± 0.35	2.23 ± 0.11	0.449

Date are presented as mean ± standard deviations; paired Student's t test was used. A = transmitral late diastolic velocity, E = transmitral early diastolic velocity, LVEDd = left ventricular end-diastolic diameter, LVEDs = left ventricular end-systolic diameter, LVEF = left ventricular ejection fraction, RT = radiotherapy
