Effects of procyanidin on the serum level of CK-MB, the expression of ROS and cardiomyocyte apoptosis (n = 10 in each group)

group	CK-MB (IU/L)	ROS	AI (%)
control	978.94 ± 8.56	4.58 ± 0.67	4.31 ± 0.74
ischemic	5045.00 ± 7.83★	22.63 ± 1.60★	21.35 ± 3.10★
Procyanidin low-dose	3883.90 ± 10.70▲	16.84 ± 1.37▲	13.45 ± 2.14▲
Procyanidin high-dose	2907.30 ± 1.07◆	12.42 ± 0.95◆	9.43 ± 1.73◆

Note: Values are mean means ± standard deviation (SD). CK-MB: creatine kinase mb isoenzyme; ROS: reactive oxygen species; AI: apoptotic index. ^★indicates compared with control group, P<0.05; ^▲indicates compared with ischemic group, P<0.05; ^◆indicates compared with procyanidin low-dose group, P<0.05
