摘要

Objectives In addition to its lipid-lowering properties, statin decreases the level of C-reactive protein (CRP) resulting in reduction of cardiovascular events. However, information about discontinuation of statin therapy in stable cardiac patients is limited. This was a prospective cohort study to explore whether withdrawal of statin treatment could result in rebound of inflammation in patients with stable angina pectoris in a short-term course.Methods and Results 75 patients with stable angina pectoris were randomly divided into three groups: ① Pretreatment with Xuezhikang (XZK, an extract of cholestin) for 6 weeks and then replaced by placebo; ②Treatment with XZK throughout the study; ③ Placebo. Lipid levels, highly sensitive CRP (hs-CRP) and serum cardiac troponin T (cTnT) were assessed before receiving the XZK therapy, 1 day before discontinuation of XZK, and on day 1, 2, 3,7 and 14 after discontinuation of XZK, respectively.At day 14 after discontinuation of XZK therapy,total cholesterol, LDL-C and triglyceride significantly increased, whereas HDL-C level significantly decreased. The median level of hs-CRP increased significantly from the second day after withdrawal of XZK therapy. There was a prominent rebound of hs-CRP concentration 3 days after discontinuation of XZK therapy. 7 to 14 days after discontinuation of XZK therapy, the hs-CRP concentration declined to a similar level as in the placebo group. Elevated cTnT level did not occur throughout the study course in either group. Conclusions Short-term discontinuation of statin therapy could induce a rapid rebound phenomenon of inflammatory response independently of changes of lipid parameters. However, it was not enough to induce myocardial injury in this cohort of patients with stable angina pectoris.
