Primary Outcome Measures:
  • Cardiac Death or Myocardial Infarction Rate in PLATINUM-like Patients [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    Cardiac death or myocardial infarction rate at 12 months post implantation in PLATINUM-like patients (no acute myocardial infarction, graft stenting, chronic total occlusion, in-stent restenosis, failed brachytherapy, bifurcation, ostial lesion, severe tortuosity, moderate/severe calcification, 3-vessel stenting, cardiogenic shock, left main disease, or acute/chronic renal dysfunction; lesion length ≤28 mm with reference vessel diameter ≥2.25 mm and <2.5 mm, or lesion length ≤24 mm with diameter ≥2.5 mm and ≤4.25 mm); statistical testing will assess if rate meets the performance goal (3.2%)


Secondary Outcome Measures:
  • Definite + Probable Stent Thrombosis (ST) Rate Based on Academic Research Consortium (ARC) Definition in PLATINUM-like Patients [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
    ARC definite/probable ST rate in PLATINUM-like patients (no acute myocardial infarction, graft stenting, chronic total occlusion, in-stent restenosis, failed brachytherapy, bifurcation, ostial lesion, severe tortuosity, moderate/severe calcification, 3-vessel stenting, cardiogenic shock, left main disease, or acute/chronic renal dysfunction; lesion length ≤28 mm with reference vessel diameter ≥2.25 mm and <2.5 mm, or lesion length ≤24 mm with diameter ≥2.5 mm and ≤4.25 mm); statistical testing will assess if the annual ST rate increase after the first year meets the performance goal (1.0%)

  • Definite + Probable Stent Thrombosis (ST) Rate Based on Academic Research Consortium (ARC) Definition in All Patients [ Time Frame: ≤24 hours, 30 days, 180 days, annually through 5 years ] [ Designated as safety issue: Yes ]
    DEFINITE ST: acute coronary syndrome and angiographic or pathologic evidence of stent thrombosis; PROBABLE ST: unexplained death within 30 days or target-vessel infarction without angiographic information ARC ST is reported as a cumulative value at different time points and within the different separate time points. Time 0 is the time point after the guide catheter has been removed. Acute ST: 0-24 hours after stent implantation; Subacute ST: >24 hours to 30 days post; late ST: >30 days to 1 year post; Very late ST: >1 year post; NOTE: Acute/subacute can be replaced by early ST (0-30 days)

  • Rate of Longitudinal Stent Deformation [ Time Frame: Index Procedure ] [ Designated as safety issue: Yes ]
    Compression/elongation of a stent along its long axis resulting from interaction with an ancillary device (e.g., guide catheter) which catches the stent end or an internal stent strut; can occur with advancement or withdrawal of ancillary device. Under fluoroscopy, longitudinal compression usually results in increased strut density and elongation in decreased strut density ('pseudo-fracture'); both can occur in the same stent. Limited data suggest coronary artery calcification, vessel tortuosity, and stent malapposition may be associated with increased risk of longitudinal stent deformation.

  • Major Adverse Cardiac Event Rate (MACE) [ Time Frame: ≤24 hours, 30 days, 180 days, annually through 5 years ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Experimental: PROMUS Element
Subjects who receive the PROMUS Element everolimus-eluting coronary stent

PROMUS Element is a device/drug combination product composed of two components, a device (coronary stent) and a drug product (a formulation of everolimus contained in a polymer coating).
Other Name: PROMUS Element stent
Drug: Aspirin
Aspirin should be taken daily (81 mg) for 3 days prior to the procedure or as a peri-procedural loading dose of 250-500 mg. A maintenance dose of aspirin of at least 81 mg daily, or as indicated by the treating physician, should be continued indefinitely.

Detailed Description:

The wide-spread use of drug-eluting stents (DES) has evolved as standard of care in de novo lesions. The PROMUS Element Plus Everolimus-Eluting Platinum Chromium Coronary Stent System is indicated for improving luminal diameter in patients with symptomatic heart disease or documented silent ischemia due to de novo lesions in native coronary arteries ≥2.25 mm to ≤4.00 mm in diameter in lesions ≤34 mm in length. The proposed study will compile real-world clinical outcomes data for the PROMUS Element Plus Everolimus-Eluting Platinum Chromium Coronary Stent System in routine clinical practice.

Patients enrolled in this study are expected to follow antiplatelet therapy recommendations per American College of Cardiology (ACC)/American Heart Association (AHA)/Society for Cardiovascular Angiography and Interventions (SCAI) guidelines for percutaneous coronary intervention (PCI). Recommended medications include aspirin, which should be taken for 3 days prior to the procedure or as a peri-procedural loading dose and then continued indefinitely. Additionally, one of the following P2Y12 antagonists may be given in a peri-procedural loading dose and in a maintenance dose per physician discretion: clopidogrel, prasugrel, ticagrelor, or ticlopidine.
