[Influence of pravastatin on blood lipids and serum high sensitive C-reactive protein in patients undergoing conventional coronary artery bypass grafting under on-pump: a clinical study of 81 cases].

OBJECTIVE: To investigate the effect of pravastatin on blood lipids and serum high sensitive C-reactive protein (HsCRP) in patients undergoing conventional coronary artery bypass grafting under on-pump bypass (CCABG). METHODS: Eighty-one patients underwent CCABG. Among which 40 took orally pravastatin 20 mg once daily to at least 28 days after operation, and 41 were used as control group. The serum levels of total cholesterol (TC), triglyceride (TG), HDL-C cholesterol (HDL-C), LDL-C cholesterol (LDL-C), and HsCRP were monitored before and 24 h, 72 h, 7 days, 10 days, 14 days, and 28 days postoperatively. RESULTS: In the control group the levels of different blood lipids after operation remarkably decreased after operation compared with those before operation (all P < 0.05), reached the lowest levels 24 h after operation, then gradually increased, however, still lower than those before operation (all P < 0.05), and recovered to the baseline level 28 hours after operation; and the HsCRP level increased 24 h after operation and peaked 72 h after, then gradually decreased, and recovered to the baseline level 28 days after operation. In the pravastatin group the TC level reached its lowest level 24 h after operation, then gradually increased, however, still lower than that before operation, and recovered to the baseline level 28 days after operation; and the TG level reached the lowest level 24 h after operation (P < 0.05), and then gradually increased 3 d after operation (P > 0.05). The TC, TG, and LDL-C levels 7, 10, 14, and 28 d after operation of the pravastatin group were all significantly lower than those of the control group (all P < 0.05). The HsCRP levels at different time points of the pravastatin group were all significantly lower than those of the control group (all P < 0.05). CONCLUSION: The use of pravastatin in the early stage of CCABG is safe and can decrease systemic inflammatory reaction.
