Outcome and selection of revascularization strategy in left main coronary artery stenosis.

Objectives: To investigate clinical outcome in unselected real-life patients with unprotected left main coronary artery (ULMCA) stenosis and determine factors associated with selection of revascularization strategy.

Design: Consecutive patients with ULMCA stenosis at our institution in 2009-2013 (n = 308) were retrospectively analyzed with propensity score adjusted Cox proportional hazards models for outcome. Baseline characteristics in relation to selection of revascularization strategy were analyzed with multivariate logistic regression.
