Ausscore Relates to Cost of Isolated CABG Surgery

Abstract

sity adjusted multivariable Cox regression did not show radial artery to be protective from mid-term mortality (p= 0.79, HR 0.97, 0.78–1.20). Furthermore, 548 patients in the radial groupwerepropensity-matched to 548 receiving only veins.At 30days, therewere comparable rates ofmortality (radial: 2% vs. vein: 3%, p= 0.19), stroke (1% vs. 1%, p= 0.51), myocardial infarction (1% vs. 1%, p= 0.77), composite MACCE (2% vs. 4%, p= 0.12), return to theatre (5% vs. 7%, p= 0.19) and hospital readmissions (12% vs. 12%, p> 0.99). At seven years, survival between radial and vein groups were also similar (79± 2.5% vs. 80± 2.5%, p= 0.74). Discussion and conclusion: This substantial multicentre analysis suggests that patients with the greatest coronary instability, urgency of surgery, or impairment of ventricular function are not disadvantaged in short-term outcome or mid-term survival by use of only a single arterial graft. Limitations include the inability to correct for unquantifiable variables retrospectively. In spite of this, surgeons may utilise clinical judgement to select radial or venous conduits to supplement the LITA according to other patient factors or technical preference without prejudicing outcome. doi:10.1016/j.hlc.2010.11.030 Ausscore Relates to Cost of Isolated CABG Surgery Diem Dinh2,∗, Andrew E.
