Table 2. Conditions affecting the susceptibility to ischemia/reoxygenation (I/R)-induced injury obtained by substracting the LDH values of the AC group from the I/R alone group for each individual patients and then compared with the mean value of the remainder study population.

Condition	N	Average LDH (AU/g. wet wt)	P–value*
With aortic valve disease	137	1.1	0.049
Without aortic valve disease	163	0.9
With dyslipidemia	161	0.9	0.045
Without dyslipidemia	139	1.1

*p values were calculated using the Mann Whitney test.
