Text: (1) 4 approximately 24 hours after the aortic cross-clamping the heart rates of the experimental group was 98 + / - 18 approximately 96 + / - 13 times/min, significantly lower than those of the control group (111 + / - 16 approximately 105 + / - 14 times/min, P < 0. 05) ; the values of rate-pressure product (RPP) of the experimental group were 13. 0 + / - 3. 7 approximately 11. 7 + / - 3. 0 mm Hg/min/10 (3), significantly lower than those of the control group (14. 1 + / - 1. 9 approximately 5. 8 + / - 3. 6 approximately mm Hg/min/10 (3), P < 0. 05) (2) The postoperative peak value of creatine kinase (CK) was not significantly different between these 2 groups.
