[Drug-eluting stent implantation for unprotected left main coronary artery disease: immediate and long-term outcomes].

Objective: To evaluate the safety and efficacy of drug-eluting stent (DES) implantation in selective patients with left main coronary artery disease.

Method: From October 2002 to November 2007, 44 consecutive patients underwent percutaneous coronary interventions (PCI) on left main coronary artery lesions, including 5 patients with concurrent left ventricular dysfunction (ejection fraction<40%), 2 with chronic respiratory dysfunction and 5 with chronic renal failure. The findings in coronary angiography, procedural success rate, severe complications and the follow-up results of the patients were analyzed.
