Long-term prognosis after coronary bypass surgery depends on interleukin 6 polymorphism and past acute infections

Int J Cardiol. 2007 Jun 12;118(3):421-2. doi: 10.1016/j.ijcard.2006.07.092. Epub 2006 Oct 4.

Abstract

We were seeking for a mutual link between the -174G>C IL6 promoter polymorphism, history of the past acute respiratory infections and the long-term post-coronary artery bypass grafting (CABG) major adverse cardiovascular events (MACE) incidence. Two hundred thirty seven post-CABG patients have been followed up for a median period of 36 months. We found that past acute infections, influenza-like illness and lack of vaccination against influenza confer a significant risk of the post-CABG MACE incidence in the -174G allele carrying patients.
