Primary Outcome Measures:
  • Composite of death, nonfatal myocardial infarction (MI), or ischemic-driven Target- Vessel Revascularization (TVR) [ Time Frame: 12 months post stenting procedure ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Death (all-cause and cardiac) [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
  • Myocardial infarction [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
  • Composite of death or MI [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
  • Composite of cardiac death or MI [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
  • Target Vessel Revascularization [ Time Frame: 30 days ] [ Designated as safety issue: No ]
  • Target lesion revascularization [ Time Frame: 30 days ] [ Designated as safety issue: No ]
  • Stent thrombosis [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]
  • Procedural success(defined as achievement of a final diameter stenosis of <30% by visual estimation, without the occurrence of death, Q-wave MI, or urgent revascularization during the index hospitalization) [ Time Frame: 3 days in average ] [ Designated as safety issue: No ]
    At discharge from the index hospitalization, participants will be followed for the duration of hospital stay, an expected average of 3 days.

  • Death (all cause and cardiac) [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • Death (all cause and cardiac) [ Time Frame: yearly up to 5 years ] [ Designated as safety issue: Yes ]
  • Myocardial infarction [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • Myocardial infarction [ Time Frame: yearly up to 5 years ] [ Designated as safety issue: Yes ]
  • Composite of death or MI [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • Composite of death or MI [ Time Frame: yearly up to 5 years ] [ Designated as safety issue: Yes ]
  • Composite of cardiac death or MI [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • Composite of cardiac death or MI [ Time Frame: yearly up to 5 years ] [ Designated as safety issue: Yes ]
  • Target Vessel Revascularization [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Target Vessel Revascularization [ Time Frame: yearly up to 5 years ] [ Designated as safety issue: No ]
  • Target lesion revascularization [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Target lesion revascularization [ Time Frame: yearly up to 5 years ] [ Designated as safety issue: No ]
  • Stent thrombosis [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • Stent thrombosis [ Time Frame: yearly up to 5 years ] [ Designated as safety issue: Yes ]

Promus Element stent
Patients receiving Promus Element stents

Detailed Description:

The Element Stent platform features a proprietary Platinum Chromium Alloy, designed specifically for coronary stents. This alloy, coupled with a new stent architecture, is designed to enable thinner struts, increased flexibility and a lower profile while improving radial strength, recoil and visibility. In addition, the PROMUS Element Stent System incorporates the new Apex™ Dilatation Catheter technology, designed to enhance deliverability to complex lesions.

Currently, there have been limited data regarding comparison of PROMUS Element stent with first-generation DES in routine clinical practice. Therefore, we perform large-scale real-world registry of PROMUS Element stents.
