Pericardial fat and postoperative atrial fibrillation after coronary artery bypass surgery

Abstract

[3], as we have a 12-year survival of 75% for left internal mammary artery (LIMA) and saphenous vein grafts and 85% for LIMA with the radial as the second graft, compared with theirs of 31 and 49%, respectively. Obesity differences between the USA and Europe may be an issue [4]. It should not be forgotten that speculation on hormone status and outcomes remains an association and not a mechanism. In addition, we are wondering why no patients after 2001 are included in their study. As pointed out in our work, males and females should be analysed separately to identify the gender differences in outcome, and we wonder if Lin et al. [2] would consider doing the same with their cohort. We have written to Buxton on this issue, but received no response. Buxton, who conducted a randomized trial regarding the radial artery and its effect on survival, failed to identify the radial artery as a beneficial factor affecting long-term survival [5, 6], and needs to be remembered by both of our groups when interpreting retrospective extensively statistically manipulated data.
