Brief Summary:
A number of 1448 patients scheduled for elective percutaneous coronary intervention (PCI) with a native coronary stenosis suitable for DES implantation and IVUS imaging are openly randomized 1:1 to either IVUS guidance or angiographic guidance groups.

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Procedure: Angiography Procedure: IVUS Procedure: DES implantation Not Applicable

Detailed Description:
The study is prospectively conducted at 8 high-volume PCI centers in China with IVUS expertise. Clinic follow-up are planned in all patients 12 months after implantation of drug eluting stents. Primary endpoint is target vessel failure. The study is powered for primary endpoint, which are likely to reach significance at the level P < 0.05 even at a follow-up drop-out rate up to 10%.

Arm Intervention/treatment
Experimental: IVUS guided DES implantation
Stent size and length were selected by online IVUS measurements, and adjunct high-pressure dilation was performed according to the discretion of operators based on the IVUS criteria for stent optimization.
 Procedure: IVUS
The size and number of stents and post-dilation will be determined on physician's discrete within the range allowed in this study protocol. All procedure will be performed according to current standard technique. IVUS will be used to assess the anatomic characteristics of lesion and determine appropriate stent size and length. Additional stent implantation or post dilation will be allowed according to attending physician's discrete based on IVUS results.
Other Name: Intravascular ultrasound

Procedure: DES implantation
Other Name: Percutaneous coronary drug-eluting stents implantation
Active Comparator: Angiography guided DES implantation
Stent size and length were chosen by visual estimation, and adjunct high-pressure dilation was performed if an optimal result was not achieved, which was defined as angiographic residual diameter stenosis 20% and absence of angiographically detected dissection.
 Procedure: Angiography
The size and number of stents and post-dilation will be determined on physician's discrete within the range allowed in this study protocol. All procedure will be performed according to current standard technique. Additional stent implantation or post dilation will be allowed according to attending physician's discrete. IVUS will be not used in this arm.

Procedure: DES implantation
Other Name: Percutaneous coronary drug-eluting stents implantation


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Target Vessel Failure [ Time Frame: 12 months ]
    The occurrence of cardiac death, target vessel myocardial infraction and target vessel revascularization.


Secondary Outcome Measures :
  1. Mortality [ Time Frame: 12 months ]
    the occurrence of 1-year all cause death

  2. Cardiac death [ Time Frame: 12 months ]
    Death that could not be attributed to a noncardiac etiology was considered cardiac death.

  3. Myocardial infarction [ Time Frame: 12 months ]
    Myocardial infarction was diagnosed by electrocardiographic changes and/or a rise and fall of creatine kinase‐myocardial band fraction in the presence of ischemic symptoms.

  4. Target vessel revascularization [ Time Frame: 12 months ]
    Target vessel revascularization was defined as repeated revascularization by PCI or surgery of the target vessel.

  5. Target lesion revascularization [ Time Frame: 12 months ]
    Target lesion revascularization was defined as any revascularization procedure performed at the site of the treated lesion associated with clinical and/or objective evidence of inducible myocardial ischemia.


Other Outcome Measures:
  1. Stent thrombus [ Time Frame: 12 months ]
    Stent thrombus was classified as definite, probable, or possible, according to the definitions provided by the Academic Research Consortium (ARC).Regarding timing, ST was defined as early (<30 days), late (30 days to 1 year), or too late (>1 year).
