Results of Hemodynamic Parameters (LVSP, LVEDP, and ± dp/dtmax) in Normal Rats and MI Rats

Group	N	LVSP (mm Hg)	LVEDP (mm Hg)	+dp/dtmax (mm Hg/ms)	−dp/dtmax (mm Hg/ms)
Sham	20	100.89 ± 10.34	7.44 ± 4.13	5.02 ± 0.39	−4.04 ± 0.31
Model	40	50.86 ± 7.92*	24.99 ± 8.05*	2.02 ± 0.34*	−2.61 ± 0.28*

Data are presented as mean ± SD. Statistical analysis was performed by Student’s t test (two-sided). LVEDP, left ventricular end-diastolic pressure; LVSP, left ventricular systolic pressure; MI, myocardial infarction. *p < 0.05 versus the sham group.
