Stents Versus Bypass Surgery for Left Main Coronary Artery Disease: 3-Year Clinical Outcomes Depending on SYNTAX Score.

The purpose of our study was to compare the 3-year of follow-up clinical outcomes in patients suffering from left main coronary artery disease (LMCAD) treated either by percutaneous coronary intervention (PCI) or by coronary artery bypass grafting (CABG) depending on SYNTAX score tertiles. The primary end point of the study was all-cause mortality for the PCI arm versus CABG arm depending on SYNTAX score tertiles. The secondary end points were the recurrence of angina pectoris following revascularization, the acute nonfatal myocardial infarction, the reduction of the left ventricular ejection fraction or the need for myocardial revascularization.

The Impact of the Risk Factors in the Evolution of the Patients with Left Main Coronary Artery Stenosis Treated with PCI or CABG.

The aim of our study was to identify the cardiovascular risk factors present in patients with left main coronary artery disease (LMCAD), which influenced the progression of these patients in both percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). We performed a clinical observational descriptive study in which, during three years, we followed the evolution of 81 patients who were diagnosed with left main coronary artery disease and who were treated either by interventional revascularization by stent implantation, by surgical revascularization by performing an aortic-coronary bypass. In our study the risk factors according to which the evolution of the patients was observed were represented by diabetes, smoking, age and gender.
