Brief Summary:
The purpose of this study is to assess the long-term clinical outcomes after stenting bifurcation coronary artery lesions, and to determine whether simple or more complex techniques are associated with a better clinical outcome. We will also assess the risk factors associated with poorer clinical outcomes

Condition or disease Phase
Coronary Artery Disease Death Myocardial Infarction Phase 4

Detailed Description:

Coronary artery disease affecting the branch points of coronary arteries (bifurcation lesions) has a higher rate of restenosis after angioplasty than disease in regions not involving branch points. Post-procedural angiographic outcomes and in-hospital outcomes have been documented for a variety of techniques, but none have examined the long-term clinical outcomes.

Long-term clinical outcomes are important from the patients point of view and also determine the use of resources. Knowledge of the long-term outcomes from the various techniques used to treat bifurcation lesions would be important in determining guidelines for the treatment of bifurcation lesions. If simple techniques offer similar or better outcomes than more complex strategies, then this would justify simpler techniques such as main vessel stenting that would use less resources, expose the patient to less radiation, and contrast related to prolonged angioplasty procedures.

Comparisons: We will compare the long-term outcomes of simple versus complex stent techniques, and determine other risk factors for long-term outcome
