Reduced P-selectin in hearts pretreated with fluvastatin: a novel benefit for patients undergoing open heart surgery

P-selectin is an adhesion molecule that plays a role in the pathogenesis of atherosclerosis. The aim of this study was to assess whether or not the treatment with fluvastatin for 3 weeks preoperatively would reduce the levels of circulating P-selectin in patients with coronary heart disease undergoing coronary artery bypass grafting surgery (CABG).

Forty-six patients referred to CABG operation were included in the study. The patients were randomized into two groups (1:1): one treated with fluvastatin (80 mg/day, fluvastatin group, n = 23), and the other one treated with placebo (placebo group, n = 23) for three weeks before surgery. All patients underwent CABG using CPB. Blood samples were collected at baseline (the day before surgery), before and after aortic cross-clamping (ACC), at postoperative 0 h (the end of surgical intervention), and at 4, 12, and 24 hours postoperatively. Concentrations of soluble P-selectin (sP-selectin) were analyzed.

The sP-selectin values measured in the fluvastatin group were significantly lower than the values measured in the placebo group. There was less use of intraoperative inotropic agents in the fluvastatin group ( P < 0.015) and the difference in the length of ICU and hospital stay showed a significantly shorter stay for the fluvastatin group.

Pretreatment with fluvastatin seemed to reduce P-selectin levels compared to patients given placebo, and hence, we think that pretreatment with a statin, fluvastatin in our study, might reduce the perioperative cardiac injury caused by cardiopulmonary bypass-induced inflammatory changes. We believe that routine preoperative use of fluvastatin should be carefully considered.
