Abstract
OBJECTIVE To conduct a randomized double-blind prospective study to investigate effect of different doses of atorvastatin, rosuvastatin, and simvastatin on elderly patients with ST-elevation AMI after PCI. METHODS One hundred and ninety-two AMI patients over 60 years old who underwent PCI were randomly divided into six groups: the low atorvastatin group, high atorvastatin group; low rosuvastatin group; high rosuvastatin group; low simvastatin group; high simvastatin group. Demographic data and clinical information as well as coronary angiography parameters were recorded. Plasma levels of CK-MB, BNP, ALT, and TnI were measured at 12 hr, 24 hr, and 1 week after PCI. Major cardiovascular events (MACE) were recorded and analyzed using Kaplan-Meier (K-M) curve. RESULTS No significant differences were observed in angiographic and procedural characteristics. In all high dose groups, all levels of CK-MB, BNP, ALT, and TnI were significantly lower. However, after 1 week of PCI, only CK-MB, BNP, and TnI showed significant difference between high and low dose groups. Patients in high dose groups had significantly lower rates for surgical or percutaneous intervention, recurrence of angina, and rehospitalization. K-M curve analysis also showed cumulative incidence freedom time of overall MACE in high dose groups was significantly longer. No significant differences were found among different drugs with the same doses. CONCLUSION Patients with higher doses had lower level of CK-MB, BNP, ALT, and TnI and lower occurrence of MACE after PCI.

Abstract
BACKGROUND Since the withdrawal of cerivastatin, statin-fibrate combination therapy has been questioned in China due to safety concern. The objective of this study was to evaluate the efficacy and safety profile of fenofibrate as an add-on in patients with dyslipidemia despite receiving statin therapy. METHODS This was a prospective, multi-center, single-arm, open-label study conducted in Chinese dyslipidemia patients with high CV risk. Fenofibrate (200mg daily) was added to the existing statin treatment for 8weeks. Lipid profile and safety parameters were measured and compared between baseline and after the treatment. Five hundred and six subjects were enrolled from 28 sites from 14 cities nationwide across China. RESULTS After 8weeks of fenofibrate treatment, the mean blood triglyceride level decreased to 1.77mmol/L (38.1% reduction vs. 3.00mmol/L at the baseline; p<0.01). Mean high-density lipoprotein cholesterol (high density lipoprotein cholesterol) was increased to 1.22mmol/L (by 17.4% from 1.07mmol/L at the baseline; p<0.01). No case of severe muscle damage (defined as elevated creatine kinase over 5 times of upper limit of normal (ULN) or rhabdomyolysis was observed. CONCLUSION In statin-treated patients with high CV risk who had elevated triglyceride, adding fenofibrate could improve lipid profile with acceptable safety profiles.
