LVIDD, cm	0.68±0.06	0.64±0.05	0.316
IVSD, cm	0.16±0.01	0.19±0.02	0.087
EF, %	80.43±3.45	70.66±8.10	0.022
E, cm/sec	68.66±9.81	33.00±13.17	<0.001

DT, ms	126.66±18.07	436.66±0.18	<0.001

Values are expressed as mean±SD. Student t test was used to compare the parameters of the standard diet and high-fat diet groups.

LVPWS, left ventricular posterior wall at systole; LVIDS, left ventricular intraventricular dimension at systole; IVSS, interventricular septum at systole; LVPWD, left ventricular posterior wall at diastole; LVIDD, left ventricular intraventricular dimension at diastole; IVSD, interventricular septum at diastole; EF, ejection fraction; E, early wave in diastole; A, atrial wave in diastole; DT, deceleration time.
