It is increasingly clear that PVD is a marker for the diffuse nature of the process and increases the risk of intervention, particularly in coronary artery bypass. The authors have reported on an impressively large series of patients, both with and without PVD, who have undergone coronary artery bypass and demonstrated both increased severity of the preoperative risk factors and the higher chance of an adverse outcome. I believe this report represents the largest single institutional evaluation of the effect of PVD on outcomes of coronary bypass.
