SAN FRANCISCO – Among patients with left main coronary artery disease and low or intermediate coronary disease complexity, no significant differences were observed between percutaneous coronary intervention and coronary artery bypass graft surgery with respect to the composite rate of death, stroke, or myocardial infarction at 5 years.
The findings come from an analysis of data from the EXCEL trial, which lead investigator Gregg W. Stone, MD, presented at the Transcatheter Cardiovascular Therapeutics annual meeting.
“PCI may be considered an acceptable revascularization modality for selected patients with left main coronary artery disease, a decision which should be made after heart team discussion, taking into account each patient’s individual risk factors and preferences,” said Dr. Stone, professor of medicine and professor of population health sciences and policy at the Icahn School of Medicine at Mount Sinai, New York.
Between September 2010 and March 2014, Dr. Stone and his colleagues at 126 sites in 17 countries enrolled 1,905 patients with left main CAD and site-assessed low or intermediate CAD complexity (SYNTAX score of up to 32) for randomization into one of two arms: 948 to revascularization with the Xience everolimus-eluting stent and 957 to coronary artery bypass graft surgery (CABG). The primary outcome was the composite of death, stroke, or myocardial infarction at 5 years. Long-term additional secondary outcomes included their components at 5 years, as well as therapy failure (definite stent thrombosis or symptomatic graft stenosis or occlusion), all revascularizations, and all cerebrovascular events (stroke or transient ischemic attack).
