Brief Summary

Coronary artery bifurcation lesions prone to occur with the worsening of atherosclerosis. Their structural properties make angioplasty technique to increase the difficulty of implementation, but also increased the risks of the in-stent thrombosis and restenosis. Standard treatment of coronary bifurcation lesions remains controversial manner, especially when the side branch (SB) was large combined with high angulated bifurcation lesions. Complex procedures and certain types of lesions are associated with poor prognosis. There is no standard treatment for such lesions even with the development of drug-eluting stents solve partial problems. The investigators reviewed patients who received coronary intervention between 2009-2012 years and met the inclusion criteria, and then analyzed the prognostic relevance of these cases the use of different treatment modalities. We introduced a retrospective analysis for high angulated bifurcation lesions treated with either DES or BMS. Primary endpoint: cardiovascular mortality, TLR, MACE. secondary endpoint: procedure time, fluoroscopy time, procedure success, angiographic success.

Outcome Measures

Primary Outcomes (2)

  • Percentage of Participants With Major Adverse Cardiac Events(MACE)

    Percentage of Participants with major adverse cardiac events(MACE) was defined as rates of target lesion revascularization (TLR) and restenosis during first post-treatment year, and rates of acute, subacute, and late in-stent thrombosis, periprocedure MI(myocardial infarction).

    periprocedure up to 12 months

  • Percentage of Participants With Cardiovascular Mortality(%)

    Percentage of Participants with cardiovascular mortality was defined as death related to cardiovascular causes within 2 years.

    periprocedure up to 12 months

Secondary Outcomes (4)

  • Percentage of Participants With Angiographic Success(%)

    periprocedure up to 12 months.

  • Percentage of Participants With Target Vessel Revascularization Rate

    periprocedure up to 12 months.

  • Fluoroscopy Time(Minutes) of Each Participants

    periprocedure up to 12 months.

  • Procedure Time(Minutes) of Each Participants

    periprocedure up to 12 months.

Study Arms (2)
