Brief Summary:
In this study, simvastatin combined with Ezeimebum was used to enhance lipid reduction, and IVUS was used to evaluate the volume and composition of coronary plaque before and after treatment. The aim is to evaluate the overall intervention effect of Ezeimebum on stable angina pectoris with diabetes mellitus on the basis of statins.

Condition or disease Intervention/treatment Phase
Coronary Heart Disease Drug: Ezetimibe with simvastatin Drug: Simvastatin Not Applicable

Detailed Description:
This study was conducted in patients with stable angina pectoris complicated with diabetes mellitus in Chinese PLA General Hospital and coronary arteriography confirmed as critical lesion of coronary artery. The patients were randomly divided into two groups: ezeimebum combined with simvastatin group and simvastatin group. The patients of the former group were given ezeimebum 10mg combined with simvastatin 40mg for 12 months while the patients of the latter group were given simvastatin 40mg for 12 months. Assessed coronary atherosclerotic plaque volume percentage (PAV) and standardized total atherosclerotic plaque volume (TAV) by intravascular ultrasound (IVUS) at the time of entry and out of the group after 12 months. The changes of PAV level in both groups were taken as the main endpoints, and the changes of TAV levels in the two groups as the secondary endpoints. The changes of serum lipids and hypersensitive C-reactive protein levels were compared between the two groups before and after the treatment. Major cardiovascular events (non-fatal myocardial infarction, all-cause death, readmission to acute heart failure, and revascularization of recurrent angina pectoris) were followed up for 12 months.

Primary Outcome Measures :
  1. Change from Baseline coronary plaque volume percentage(PAV) at 12 months [ Time Frame: 12 months after PCI ]
    PAV=∑((ESA CSA-lumen CSA)/(ESA CSA))x100, EEM CSA:cross-sectional area of outer elastic membrane boundary; lumen CSA: cross-sectional area of tube boundary


Secondary Outcome Measures :
  1. Change from Baseline standardized coronary plaque volume(TAV) at 12 months [ Time Frame: 12 months after PCI ]
    TAV= (median number of images in ∑ (ESA CSA-lumen CSA) / retracement) x number of images (standardized according to the length of IVUS retracement, To ensure that each individual patient has the same weight)

  2. LDL-C [ Time Frame: follow up in one year ]
    Low density lipoprotein cholesterol (LDL-C)

  3. HDL-C [ Time Frame: follow up in one year ]
