Hemodynamics for the four different groups of rats ( n = 8 per group). Right ventricular systolic pressure for the four groups: Group A: 25.2 ± 3.3 mmHg, Group B: 26.8 ± 2.1 mmHg, Group C: 34.3 ± 4.2 mmHg, Group D: 28.6 ± 4.6 mmHg. Data are expressed as means ± standard error of mean. * P < 0.001 vs Group A and Group B; # P < 0.05 vs Group C; $ P < 0.05 vs Group A and Group B.
