TABLE 2.

The effect of microgravity on ventricular thickness and volume of rats.

	Control	Microgravity
LVM (g)	0.65 ± 0.03	0.39 ± 0.06**
LVEDV (mL)	0.69 ± 0.08	0.50 ± 0.05**
LVPWd (cm)	0.16 ± 0.01	0.14 ± 0.01**
LVPWs (cm)	0.27 ± 0.02	0.24 ± 0.02*

Data are presented as mean ± SD; n = 7. *P < 0.05, **P < 0.01 vs. control group. LVM, left ventricular mass; LVEDV, left ventricular end-diastolic volume; LVPWd, left ventricular posterior wall thickness at end diastole; LVPWs, left ventricular posterior wall thickness at end systole.
