LAP +10 mmHg	13.9 ± 0.5‡	28.6 ± 2.5§	172.6 ± 8.3	7.4 ± 0.4
Rabbits with chronic mitral regurgitation
Baseline	5.8 ± 0.7†	56.8 ± 9.3	196.8 ± 9.0	.6 ± 0.6
LAP +25 mmHg	27.1 ± 3.9‡	27.7 ± 5.5§	144.0 ± 6.0‡	6.0 ± 0.8
Age-matched intact control rabbits
Baseline	2.4 ± 0.3	58.2 ± 4.5	169.0 ± 8.0	5.0 ± 0.5
LAP +10 mmHg	13.6 ± 0.5‡	32.6 ± 4.9‡	170.6 ± 5.8	5.8 ± 0.4

^†Significantly higher than that of age-matched control rabbits at baseline (P < 0.01, t test).

^‡Significantly different from the baseline value of the same group of rabbits (P < 0.01, t test).

^§Significantly lower than the baseline value of the same group of rabbits (P < 0.05, t test).

^‖Significantly higher than that of the baseline value of the age-matched control group and the other group of rabbits with chronic mitral regurgitation (P < 0.05, t test).
