Résumé
OBJECTIVE@#To determine the effect of different doses of atorvastatin on the serum soluble intercellular adhesion molecules-1 (sICAM-1) in patients undergoing percutaneous coronary intervention (PCI).@*METHODS@#The study consisted of 38 patients with unstable angina and 10 patients with old infarction who underwent elected PCI for stenotic lesions of the coronary artery. Patients were randomly assigned to either aggressive group or conventional one. After PCI the patients took atorvastatin 20 mg per day or 10 mg per day. Blood lipid profile was examined before, and 3 months after the PCI. SICAM-1 was examined before the PCI, 48 hours and 3 months after the PCI.@*RESULTS@#The total cholesterol and LDL-Cholesterol 3 months after the PCI in the 2 groups were lower than those before the PCI (P0.05). sICAM-1 in the 2 groups 48 hours after the PCI significantly higher than that before the PCI (P<0.01). But sICAM-1 in the 2 groups 3 months after the PCI significantly lower than that before the PCI (P<0.01 or P<0.05). The aggressive group showed greater reduction than the conventional group (P<0.01). TC and LDL-C were positively correlated with sICAM-1(r=0.2413, r=0.2691, all P<0.05).@*CONCLUSION@#Atorvastatin 20 mg per day reduces TC, LDL-C, and sICAM-1 to a greater extent than atorvastatin 10 mg per day. The effect on sICAM-1 is partly related to reduce lipid profile.
