Brief Summary:
To determine whether, on a background of optimal medical therapy, including ticagrelor, opening of all suitable narrowings or blockages found at the time of primary PCI for an acute heart attack is better than treating only the culprit lesion in patients with multi-vessel disease.

Condition or disease Intervention/treatment Phase
Acute Myocardial Infarction Coronary Artery Disease Procedure: Complete Revascularization Strategy Not Applicable

Detailed Description:
To determine if a strategy of multivessel revascularization involving PCI of all suitable non-infarct related artery lesions plus optimal medical therapy is superior to a strategy of optimal medical therapy alone in reducing (1) the composite outcome of cardiovascular (CV) death or new myocardial infarction (MI), or (2) the composite of CV death, new MI or ischemia driven revascularization (IDR) in patients with multivessel disease who have undergone early successful culprit lesion PCI for STEMI.

Arm Intervention/treatment
Active Comparator: Complete Revascularization Strategy

Complete Revascularization Strategy (Staged Non-Culprit Lesion PCI plus Optimal Medical Therapy): Staged PCI using second generation drug eluting stents (Promus Element Plus drug-eluting stent or newer version in this series is strongly recommended) of all suitable non-culprit lesions.

All patients, regardless of randomized treatment allocation will receive optimal medical therapy consisting of risk factor modification and use of evidence-based therapies (including low dose acetylsalicylic acid (ASA) and ticagrelor).

 Procedure: Complete Revascularization Strategy
Staged PCI using second generation drug eluting stents (Promus Element Plus drug-eluting stent or newer version in this series is strongly recommended) of all suitable non-culprit lesions plus optimal medical therapy.
Other Name: Staged Non-Culprit Lesion PCI plus Optimal Medical Therapy
No Intervention: Optimal Medical Therapy Alone

Culprit lesion only Revascularization Strategy (Optimal Medical Therapy Alone): No further revascularization of non-culprit lesions.

All patients, regardless of randomized treatment allocation will receive optimal medical therapy consisting of risk factor modification and use of evidence-based therapies (including low dose ASA and ticagrelor).

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Men and women within 72 hours after successful PCI (preferably using a drug eluting stent) to the culprit lesion for STEMI. PCI for STEMI can be either primary PCI or rescue PCI for failed fibrinolysis or a combination strategy where PCI is performed routinely 3-12 hours after fibrinolysis AND

  2. Multi-vessel disease defined as at least 1 additional non-infarct related coronary artery lesion that is at least 2.5 mm in diameter that has not been stented as part of the primary PCI and that is amenable to successful treatment with PCI and has:

    • At least 70% diameter stenosis (visual estimation) or
    • At least 50% diameter stenosis (visual estimation) with fractional flow reserve (FFR) ≤ 0.80

Exclusion Criteria:

  1. Planned revascularization of non-culprit lesion
  2. Planned surgical revascularization
  3. Non-cardiovascular co-morbidity reducing life expectancy to < 5 years
  4. Any factor precluding 5 year follow-up
  5. Prior Coronary Artery Bypass Graft (CABG) Surgery
