Brief Summary:
The CLEAR SYNERGY trial will study the long term effects of treatments following PCI to treat myocardial infarction. These treatments address both the culprit artery (PCI with SYNERGY stent) as well as the non-culprit arteries (randomization to routine colchicine and spironolactone).

Condition or disease Intervention/treatment Phase
ST Elevation Myocardial Infarction Non ST Elevation Myocardial Infarction Drug: Colchicine Drug: Spironolactone Device: SYNERGY Bioabsorbable Polymer Drug-Eluting Stent Drug: Colchicine-Placebo Drug: Spironolactone-Placebo Phase 3

Detailed Description:
This is a multicenter, international SYNERGY stent registry that is embedded within a randomized, blinded, double-dummy, 2x2 factorial design trial of colchicine versus placebo and spironolactone versus placebo in patients with myocardial infarction who have undergone primary percutaneous coronary intervention (PCI).

Primary Outcome Measures :
  1. Major Adverse Cardiac Events (MACE) [ Time Frame: up to 1 year ]
    Major Adverse Cardiac Events (MACE) for SYNERGY Stent (defined as the composite of death, recurrent target vessel MI, stroke, or ischemia driven target vessel revascularization) compared to performance goal

  2. Composite of cardiovascular death, recurrent myocardial infarction, or stroke [ Time Frame: through study completion, an estimated average of 2 years ]
    The first occurrence of cardiovascular death, recurrent myocardial infarction, or stroke in the colchicine comparison

  3. Composite of cardiovascular death or new or worsening heart failure [ Time Frame: through study completion, an estimated average of 2 years ]
    The first occurrence of cardiovascular death or new or worsening heart failure in the spironolactone comparison
