OBJECTIVE: To investigate whether intensive statin therapy during the perioperative period improves outcomes in patients undergoing middle cerebral artery (MCA) stent implantation for ischemic stroke.
METHODS: Forty patients with ischemic stroke undergoing delayed stent implantation in our department from January, 2010 to November, 2014 were randomized to intensive statin group (atorvastatin, 80 mg/day, 3 days before till 3 days after intervention; n=20) and standard therapy group (atorvastatin, 20 mg/day, n=20). All the patients received long-term atorvastatin treatment thereafter (20 mg/day). Serum levels of C-reactive protein (CRP), vascular cell adhesion molecule-1 (VCAM-1), and soluble extracellular matrix metalloproteinase inducer (EMMPRIN/CD147) were measured at 24 h before and 24 h after the intervention. The primary end point was procedure-related intra-stent thrombosis, 1-month incidence of major adverse cerebrovascular events (stroke, transient ischemic attack, in-stent restenosis, death or unplanned revascularization).
RESULTS: The basic clinical data were similar between the two groups before the intervention (P>0.05). In the intensive therapy group, the levels of CRP, VCAM-1, and sCD147 were significantly lower at 24 h after the intervention than the levels before intervention (P<0.05) and the postoperative levels in the standard therapy group (P<0.05). The levels of CRP, VCAM-1, and sCD147 were all increased after the intervention in the standard therapy group (P>0.05). The incidence of primary end point was lower in intensive therapy group than in standard therapy group (P<0.05).
CONCLUSION: In patients undergoing MCA intravascular stent implantation for ischemic stroke, perioperative intensive statin therapy improves the patients' outcomes, reduces the levels of CRP, VCAM-1 and sCD147 molecules, and lowers the incidences of cerebrovascular events.
