In patients with unprotected left main disease (ULMD), angioplasty is emerging as an alternative technique. The investigators aimed to determine the rate of major cardiovascular events in patients treated by angioplasty for ULMD in a "real world" registry.

Primary Outcome Measures:
  • Major cardiovascular events (MACCE) [ Time Frame: One year ]
    Major cardiovascular events (MACCE)were measured after 1 year follow-up. MACCE included all-cause of death, stroke, myocardial infarction, and repeat revascularizations. Non-Q-wave myocardial infarction was defined using universal definition with troponin I. Stent thrombosis was defined according to the Academic Research Consortium definition as definite, probable, or possible and as early or late after the index procedure. Repeat revascularization was composed of any repeat percutaneous intervention or surgical bypass.

Angioplasty of left main

Patients with:

  • stable or unstable angina and/or documented ischemia
  • de novo ≥50% stenosis in the left main stem referred for angioplasty

Detailed Description:

Current guidelines recommend coronary artery bypass graft surgery as the "gold standard" treatment in patients with unprotected left main disease. However, patients with ULMD and high surgical risk score or favourable anatomy are still referred for angioplasty. Recently, several studies and registries comparing surgery and percutaneous intervention with drug eluting stents report similar results regarding cardiovascular death and myocardial infarction in patients with multivessel coronary artery disease including unprotected left main disease.

The aim of the study is to evaluate major cardiovascular events in a "real world" registry.
