Coronary Artery Bypass Grafting in Argentina. Subanalysis of the ARGEN-CCV Registry

pp. 353-358

Abstract

Background: Coronary artery bypass grafting (CABG) continues to be widely used to treat coronary artery disease, mainly in patients with technical difficulties in performing angioplasty, as well as in patients with diabetes mellitus. CABG data from the ARGEN-CCV registry are presented. This registry shows the current data on cardiovascular surgery (CVS) in Argentina.
Objective: To determine the in-hospital course of patients undergoing CABG.
Methods: ARGEN-CCV is a prospective, multicenter registry of patients undergoing CVS in Argentina, from which peripheral vascular surgery and repair of congenital heart disease were excluded. For this analysis, only patients who underwent CABG were analyzed.
Results: A total of 700 patients were included. Seventy percent (70%) were elective surgeries, and extracorporeal circulation (ECC) was used in 50.6% of the cases. In total, 38.6% of patients were diabetic, 22.4% had a history of left ventricular dysfunction and 38.1% had left main coronary artery disease. The left internal mammary artery to the left anterior descending artery graft was the most commonly used (94.6%). The recorded mortality was 6.9% and in patients with left ventricular dysfunction it was 13.1% vs. 5.1% in the rest (p<0.001). In the multivariate analysis 3 post-surgical variables, inotropic use, low cardiac
output syndrome and renal failure, were predictors of mortality, strongly influenced by a history of left ventricular dysfunction.
Conclusion: We observed a high percentage of patients with diabetes and patients with left main coronary artery disease as well as high surgical morbidity and mortality, particularly in those patients with left ventricular dysfunction.
