Abstract
Objective: The aim of our study was to evaluate the effects of two different statins and a statin/ezetimibe combination on high sensitive C-reactive protein (hsCRP) values, which were given at high doses in the early period of acute coronary syndromes. Methods: A total of 150 patients with non-ST elevation myocardial infarction and unstable angina pectoris were enrolled to our prospective, randomized, single-blind study. Patients were divided into three groups by block randomization method. One group received 20mg/day atorvastatin, one group received 10 mg/day rosuvastatin and the other group received 10 mg/day ezetimibe/simvastatin combination therapy, which was initiated within the first 24 hours of admission. Follow-up duration was 2 months. Biochemical investigations and hsCRP levels (by nephelometric method) were performed with 138 patients evaluated at baseline, 10th and 60th days of therapy. Decreases of hsCRP levels were analyzed with one-way MANOVA and repeated measures of ANOVA methods. Post-hoc Tukey HSD test was performed for finding the different group, when the difference was detected between the groups. Results: Tenth day hsCRP levels in ezetimibe/simvastatin group was significantly lower than the other groups (p<0.001). Further, after 60 days of follow-up a significant reduction was seen in hsCRP levels in ezetimib/simvastatin group (in ezetimibe/simvastatin group the mean hsCRP was reduced from 38.4±15.0 mg/L to 2.4±1.3 mg/L, in atorvastatin group the mean hsCRP was reduced from 27.3±11.7 mg/L to 4.1±2.4 mg/L and in rosuvastatin group the mean hsCRP was reduced from 22.0±6.9 mg/L to 3.6±1.7 mg/L (F (1.1, 148.2) = 746.9, p<0.01 and the difference between drugs; F (2.2, 148.2) = 32.1, p<0.01). No side effects related to drugs were seen during follow-up in all three treatment groups. Conclusion: This study showed that ezetimibe/simvastatin 10 mg/day combination treatment was superior to atorvastatin 20 mg/day and rosuvastatin 10 mg/day treatment in reducing the inflammatory markers when high dose statins was started in the early period of unstable angina and non ST elevation myocardial infarction.
