Brief Summary:
An investigator-driven, retrospective study to compare long-term survival-data (10-year follow-up) of patients with coronary artery disease (CAD), previously enrolled in the SYNTAX trial, who were randomized to percutaneous coronary intervention (PCI) using a paclitaxel (TAXUS) drug-eluting-stent (DES) or coronary artery bypass grafting (CABG).

Condition or disease Intervention/treatment
Coronary Artery Disease Other: No intervention will take place for this retrospective and observational study.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Patients enrolled in the SYNTAX trial and registries had to be diagnosed with three-vessel (3VD) or left main (LM) coronary artery disease. The vessels (diameter ≥1.5 mm and significant stenosis > 50%) deemed important to revascularize were determined by the Heart Team prior to randomization. The group of 3VD consists of patients with significant stenosis in vessels supplying all three major epicardial territories in absence of LM disease, as determined by the site investigators. The group of patients with LM disease consists of patients with a significant stenosis of the left main coronary artery, irrespective of additional vessel disease.
Criteria
Patients which have previously been enrolled in the SYNTAX trial (randomized and registry patients)
