Abstract

The present study was conducted to investigate whether upper-extremity vascular access (VA) creation increases the risk for major adverse cardiac events (MACE) and death in patients undergoing coronary artery bypass grafting (CABG) with an in situ left internal thoracic artery (ITA) graft. A total of 111 patients with CABG with a left ITA graft who underwent upper-extremity VA creation were analyzed retrospectively; 93 patients received left VA creation (83.8%, ipsilateral group) and 18 patients received right VA creation (16.2%, contralateral group). The primary outcome was the occurrence of MACE, and the secondary outcome was the composite of MACE or late death. There were no significant differences in the incidence of primary (P = 0.30) or secondary (P = 0.09) outcomes between the two groups. Multivariate regression analysis indicated that prior cerebrovascular accidents (hazard ratio [HR] 3.30; 95% confidence interval [CI] 1.37-7.97; P = 0.01) and type of VA (HR 3.44; 95% CI 1.34-8.82; P = 0.01) were independently associated with MACE; prior peripheral arterial occlusive disease (HR 4.22; 95% CI 1.62-10.98; P<0.01) and type of VA (arteriovenous fistula vs. prosthetic arteriovenous grafting) (HR 3.06; 95% CI, 1.42-6.61; P<0.01) were associated with the composite of MACE or death. The side and location of VA were not associated with MACE or death. Our study showed no definite evidence that ipsilateral VA creation affects the subsequent occurrence of MACE or late death from any cause. The type of VA (a prosthetic arteriovenous grafting) is a significant predictor of the subsequent occurrence of MACE or late death.
