LVAW;s	1.39 ± 0.03	1.51 ± 0.04	0.03
LVPW;d	0.74 ± 0.03	0.77 ± 0.03	0.40
LVPW;s	1.00 ± 0.03	1.01 ± 0.03	0.84
%FS	28.21 ± 0.59	30.34 ± 0.96	0.06
%EF	55.06 ± 0.91	58.20 ± 1.37	0.06

LVID: left ventricular internal diameter, LVAW: left ventricular anterior wall thickness, LVPW: left ventricular posterior wall thickness, %FS: percentage fractional shortening, %EF: percentage ejection fraction, ;d is during diastole, and ;s is during systole. Data are presented as mean ± sem, and were tested with a 2-tailed Student’s t-test.
