Abstract:

Importance: despite generally promising outcomes after stenting for unprotected left main coronary artery (ULMCA) disease, the ULMCA bifurcation lesions remain challenging, and their restenosis rate is still relatively high.

Objective: aim of the current study was to analyze possible factors influencing one year MACE rate in distal ULMCA patients.

Design, setting and patients: from year 2002 until end of year 2011 at Latvian Centre of Cardiology Pauls Stradins Clinical University hospital in ULMCA registry 1052 patients were enrolled. Interventions: In 723 patients distal bifurcations were treated, out of them in 449 patients one year follow-up were completed and those patients were included in current analyses Main outcome measures: cardiac death, target vessel revascularization (TVR), target lesion revascularization (TLR), major cardiac adverse events (MACE) were assessed at one year.

Results: two stent technique was used in 8,5% of cases. MACE, cardiac death, TVR and TLR rates at one year was 15,6%, 2,9%, 4,7% and 12,9%, respectively Cardiac death was associated with diabetes mellitus and NSTEMI, however, TLR was associated with SYNTAX score >30. MACE was associated with NSTEMI and 2 stent technique. True bifurcation was not associated with adverse cardiovascular outcomes.

Conclusions: Use of two stent technique and NSTEMI at presentation were associated of MACE at one year in distal ULMCA patients.
